Competition Updates, Race for Milestones To Begin on Streets of St. Petersburg for NTT INDYCAR SERIES, INDY NXT by Firestone

INDIANAPOLIS (Monday, Feb. 23, 2026) – With a record four races in March, there has never been a faster-paced start to an NTT INDYCAR SERIES season, and the 2026 championship begins Sunday, March 1, at the Firestone Grand Prix of St. Petersburg on the Streets of St. Petersburg, Florida.

A return to historic Phoenix Raceway, a can’t-miss and much-anticipated inaugural event on the Streets of Arlington and another trip to the picturesque and physically demanding Barber Motorsports Park will set the stage for another record-making 2026 season.

For the first time since 2014, North America’s premier open-wheel series will feature an 18-race championship. For the second year, FOX Sports will provide coverage of all on-track sessions, including all 18 races scheduled to air on FOX. With two additional appearances on broadcast television during PPG Presents Armed Forces Qualifying on May 16-17 ahead of the 110th Running of the Indianapolis 500 presented by Gainbridge, FOX will provide a record 20 network windows for “The Fastest Racing on Earth.”

The NTT INDYCAR SERIES is the only premier motorsport series in North America with all races broadcasting on network television. All INDYCAR programming also streams live on FOX One and the FOX Sports app.

“Coming off a 2025 season of massive and historic growth with FOX Sports, 2026 has all the makings of another incredible year,” INDYCAR President J. Douglas Boles said. “The addition of new events at Phoenix, Arlington, Markham and Washington D.C., combined with integration around this summer’s FIFA World Cup 2026™ on FOX, will provide even greater opportunity to showcase the ultra-competitive, wheel-to-wheel racing and dynamic driver personalities that the NTT INDYCAR SERIES is known for.

“We cannot wait to see what happens during the 2026 championship and the battle for the Astor Challenge Cup, beginning with the Firestone Grand Prix of St. Petersburg.”

Milestones in the Making

Drivers will take aim at several milestones throughout the 2026 NTT INDYCAR SERIES season. The next first-time winner in the series will mark the 300th all-time race winner in the history of the INDYCAR SERIES.

Four-time series champion and winner of three consecutive titles, Alex Palou of Chip Ganassi Racing, looks to become only the second driver to win four consecutive championships, joining Sebastien Bourdais in 2007.

Six-time series champion Scott Dixon of Chip Ganassi Racing will attempt to extend all-time records for:

  • Seasons with a win (23)
  • Consecutive seasons with a win (21)
  • Consecutive starts (356)
  • Starts (419)
  • Podiums (145)
  • Top fives (216)

Will Power, who joined Andretti Global starting this season, looks to extend his all-time record for pole positions earned (71).

Several other drivers are on pace to make a milestone 100th career NTT INDYCAR SERIES race start:

  • Palou: scheduled at Phoenix Raceway
  • Rinus VeeKay (Juncos Hollinger Racing): scheduled at Streets of Arlington
  • Santino Ferrucci (AJ Foyt Racing): scheduled at Indianapolis 500 presented by Gainbridge
  • Scott McLaughlin (Team Penske): scheduled for Milwaukee Mile race 1

Doubling Down on the Streets

INDYCAR is updating the race tire usage requirements for all street circuit events in 2026. Beginning with the Firestone Grand Prix of St. Petersburg, teams will be required to use:

  • One set of primary compound tires
  • Two sets of alternate compound tires (one more than previously required)

There are no requirements in terms of new (sticker) sets of tires used in the race. The two completed laps needed to satisfy the tire requirement rule, where one lap must begin once the Green Flag has been displayed to the Race Leader (Rule 15.3.3.2.3.) for each of the three sets (Rule 15.3.3.2.) remains in effect.

The update challenges drivers and teams to compete with a more varied strategy choice on higher drop-off (alternate) Firestone race tires, which INDYCAR believes will bring race quality to an even higher level and create even more wheel-to-wheel action.

Ultimately, doubling the use of street circuit alternate tires, which Firestone has designed to have less drop-off in 2026, strives to ensure an all-out driving on the limit, a thrilling and entertaining product for fans that generates even more strategic challenges.

“INDYCAR is always looking into ways to improve the quality of what is already exceptional on-track action,” INDYCAR Senior Vice President, Competition and Operations Mark Sibla said. “This street circuit update will challenge drivers and strategists alike and provide an avenue for even more memorable wheel-to-wheel action at our fan-favored street events in 2026.”

Process and Practice

INDYCAR is also updating late-race procedures for 2026. To generate more lead-lap battles in the closing stages of races, the lap windows – in which cars that are a lap down to the leader and moved to the rear of the field before restarts – will be expanded at almost all races.

Additionally, updates to NTT INDYCAR SERIES road and street course practices include:

Practice 2 will now mirror the “group” format of Practice 1, where the field is split by odd and even numbered pit boxes. All cars will receive an initial 40-minute practice segment before the start of two 12-minute group segments.
With the change to Practice 2, qualifying groups will now be determined by the qualifying results from the previous 2026 race (2025 championship entrant points for the season opener on the Streets of St. Petersburg).
Traditional pre-race “warmup” sessions will expand from 25 to 30 minutes in 2026. FOX Sports’ coverage of warmup sessions will also increase to robust one-hour telecasts.

Technical Updates Focus on Safety at Indianapolis 500

In collaboration with Dallara, INDYCAR is mandating the use of superspeedway tire ramp flaps for all sessions at Indianapolis Motor Speedway, including the Indianapolis 500.

The carbon fiber flaps, connected to the aerodynamic “ramps” located directly in front of the rear tires, are a continuation in the effort to increase aero stability of cars and will deploy – rising from the aft area of the flap – to disrupt air flow “lift” during a spin.

“Dallara is a tremendous partner and have joined us to closely examine spins that have occurred over the last few years at IMS,” INDYCAR Director of Aerodynamic Development Engineering Tino Belli said. “This update to the rear tire ramps has proven in computational fluid dynamics testing to decrease, by nearly 9 percent, the likelihood of a car at speed ‘lifting’ after a 180-degree spin. We are always evaluating safety and, from a car perspective, believe this is an effectual development for a superspeedway.”

Use of these new tire ramp flaps will be required beginning at the Indy 500 Open Test on April 28-29 at IMS.

Additionally, oval testing at IMS performed by “500” champions Alexander Rossi and Takuma Sato in October 2025 validated the performance of Performance Friction Corporation’s speedway-specific brake configuration. In recent Indy 500s, incidents have occurred where drivers have struggled to slow or control their cars coming off Turn 4 and entering pit lane. The new brake configuration is more predictable and responsive, increasing safety.

What’s NXT: Larger Field, More Opportunities on FOX Sports for INDY NXT

An era of unprecedented exposure continues for INDYCAR’S development series, INDY NXT by Firestone, as a record 17 races will air on live television. Last year marked the first year a full INDY NXT season was available on live TV. In 2026, 15 of the 17 championship rounds will air on FOX Sports’ FS1, with two airing on FS2.

Once again this season, all INDY NXT practice and qualifying sessions also will air on a combination of FS1, FS2, the FOX One and the FOX Sports app.

The 17-race schedule includes a series-record-tying four races in March and the addition of three new doubleheader weekends as the series looks to better prepare drivers and team personnel for the skills required to advance to the NTT INDYCAR SERIES.

For the second consecutive season, a growing paddock will compete for the championship, with 24 drivers representing 11 countries beginning the season on the Streets of St. Petersburg. It is the most entries to start a season since 2009 (27 entries).

Team lineups again will be a key storyline, with eight powerhouse organizations helping fuel the series’ competitive balance and championship intrigue. AJ Foyt Racing will make its second foray in INDY NXT and first full-time effort since 2004.

Cusick Morgan Motorsports competes in INDY NXT for the first time, fielding two cars in the championship. Chip Ganassi Racing enters its second consecutive season and expands to four cars this season.

Additionally, Cape Motorsports powered by ECR marks ECR’s debut in the INDY NXT paddock, entering two cars into the championship. Juncos Hollinger Racing also returns for its 10th season in INDY NXT.

“The 2026 INDY NXT by Firestone season reflects the momentum our series has built over the past few years, with an expanded number of races that deliver more competition, more chances for drivers to sharpen their race craft and more value for the series overall,” INDY NXT director Kirk Dooley said. “That added on-track action comes alongside growth in car counts and new teams joining the grid, making 2026 one of our most exciting seasons yet.”

From a rules perspective, group qualifying sessions on road and street courses have been updated to 10-minute sessions, with the provision of one clock stoppage should a red flag occur in each group. The updated timing format more closely matches that of the NTT INDYCAR SERIES and continues the series’ integration with INDYCAR, which began in 2022.

The pathway to North America’s premier open-wheel series once again features a total purse of just over $1 million. The series champion will receive $850,000 to be applied to a rookie oval test, the Indy 500 Open Test and Rookie Orientation Program, an entry for the 2027 Indianapolis 500 and an entry for an additional NTT INDYCAR SERIES event.

INDYCAR’s worldwide direct-to-consumer streaming platform, INDYCAR LIVE, has access to a full library of archived INDY NXT practices, qualifying sessions, races and additional content. 2026 INDY NXT sessions and races will stream live in certain countries and territories. More information is available here.

Coverage of the 2026 NTT INDYCAR SERIES season debut at the Firestone Grand Prix of St. Petersburg begins at noon ET Sunday, March 1 on FOX. A Spanish-language version will be available on FOX Deportes.

INDY NXT by Firestone’s season opener begins earlier that day on the Streets of St. Petersburg at 10 a.m. ET on FS1.

The award-winning INDYCAR Radio Network also will provide coverage throughout the 2026 NTT INDYCAR SERIES and INDY NXT seasons with audio available via SiriusXM channel 218 and the INDYCAR App powered by NTT DATA.

COTA Keeps Austin ‘Wheeled’: Cody Ware Relishes NASCAR’s Brand of Road Racing at Formula 1 Facility

By
Official Release

MOORESVILLE, N.C. (Feb. 23, 2026) – The unofficial slogan is “Keep Austin Weird,” an acknowledgement of the Texas city’s eclectic style whose inhabitants take pride in zigging while others zag.

That Austin is also home to the first road-course race on the NASCAR Cup Series schedule fits with the town’s mantra. The predominantly oval racing series switches things up at Circuit of the Americas (COTA) and keeps Austin “wheeled” as drivers wrestle their 3,400-pound stock cars around the track’s 2.4-mile, 20-turn layout in Sunday’s DuraMax Grand Prix powered by RelaDyne.

And unlike Formula 1, the globe-trotting open-wheel series for which COTA was purposely built for in 2012, you won’t hear talk of track limits or avoidable contact or anything being referred to stewards for review. No, Cup Series drivers prefer to handle things on the racetrack, and at COTA, justice is served with a slam of the bumper and a wheel to the door.

“NASCAR is a contact sport on road courses,” said Cody Ware, driver of the No. 51 Parts Plus/Costa Oil 10-Minute Oil Change Chevrolet for Rick Ware Racing (RWR). “We go into it with a have-at-it mentality, to where if there’s a racing surface that you can plant four tires on, you do it. Beating and banging is expected. It’s very different from the etiquette and thought process behind road racing anywhere else.”

Ware knows. He won the 2019-2020 LMP2 championship in the Asian Le Mans Series with co-driver Gustas Grinbergas, and in a prelude to that title, Ware was the 2014 Lamborghini Super Trofeo North America Rookie of the Year. In January 2024 at Daytona (Fla.) International Speedway, Ware piloted a Ligier JS P320 to a podium finish in the IMSA VP Racing SportsCar Challenge LMP3 class. He has also competed in Whelen Mazda MX-5 Cup and the NTT IndyCar Series.

“If you go anywhere else and you even breathe on someone the wrong way, you’re penalized and get a drive-thru penalty,” Ware said. “In other series, there are so many rules and regulations on how to pass and when to pass and when you have to let somebody go, you feel like you’re not able to race at your full capacity.”

Full capacity is the name of the game in NASCAR. It’s expected of the drivers, and it’s the drivers’ expectation of their racecars.

“Our cars can take the hits, they can take the rubbing, they can take the racing. They’re very durable. Our races have become more of a left-and-right-turn short-track race than a road-course race,” Ware said.  

“Sportscars are very fragile compared to stock cars. If you’re in a dedicated sportscar series, you give someone a donut, that can rip off a body panel, or if you hit them too hard from behind, their wing falls off.”

The no-holds-barred nature of Cup Series road-course racing has made for compelling viewing, be it in person or on TV.

“NASCAR racing on road courses right now is some of the best it’s ever been. We have a lot of parity from first to last,” Ware said. “Whether we’re racing in the dry or racing in wet conditions, everyone’s gotten really good at road racing, so we put on a great race.”

COTA delivers great racing from the outset, as its most drama-filled corner is turn one. That’s where the 38-car field attempts to funnel itself through an ultra-tight left-hander after scaling a 133-foot hill with a 17 percent gradient.

“The aggression level of the guys you have in front of you and behind you, it’s almost similar to a speedway race,” said Ware about tackling turn one at the start and on subsequent restarts. “It’s about knowing who you can work with to try to get some track position on those restarts versus not wanting to be around someone that might approach turn one like a wrecking ball.”

After turn one, the remaining 19 corners remain on brand for Austin.

“COTA takes a blend of everything,” Ware said. “It’s finesse and perfection, but also ruggedness and manhandling where you’re throwing the car around in different directions.”

Ware and his Cup Series counterparts begin navigating COTA’s confines on Saturday at 9 a.m. CST/10 a.m. EST for a one-hour practice before qualifying at 10:10 a.m. CST/11:10 a.m. EST. Prime Video and SiriusXM NASCAR Radio will provide live coverage of both. Sunday’s DuraMax Grand Prix powered by RelaDyne goes green at 2:30 p.m. CST/3:30 p.m. EST with live, flag-to-flag coverage delivered by FOX and SiriusXM NASCAR Radio.

About Rick Ware Racing:

Rick Ware has been a motorsports mainstay for more than 40 years. It began at age 6 when the third-generation racer began his driving career and has since spanned four wheels and two wheels on both asphalt and dirt. Competing in the SCCA Trans Am Series and other road-racing divisions led Ware to NASCAR in the early 1980s, where he finished third in his NASCAR debut – the 1983 Warner W. Hodgdon 300 NASCAR Grand American race at Riverside (Calif.) International Raceway. In 1995, Rick Ware Racing was formed, and with wife Lisa by his side, Ware transitioned out of the driver’s seat and into fulltime team ownership. He has since built his eponymous organization into an entity that competes full-time in the elite NASCAR Cup Series while simultaneously campaigning winning teams in the Top Fuel class of the NHRA Mission Foods Drag Racing Series, Progressive American Flat Track (AFT), FIM World Supercross Championship (WSX) and zMAX CARS Tour.

TopLiner Makes Standout Debut Performance at EchoPark Speedway

Atlanta, GEORGIA — February 23, 2026 – TopLiner™ proudly celebrates a remarkable NASCAR Craftsman Truck Series debut for Adam Andretti at EchoPark Speedway, where the experienced road racer showcased his resilience, race craft, and determination en route to an impressive 12th-place finish on the 1.54-mile paved oval.

Driving the rotating No. 5 entry for TRICON Garage, Andretti wasted no time making his presence known. In qualifying, he powered the TopLiner™ supported truck to an outstanding eighth-place starting position (P8), immediately turning heads in his NASCAR Craftsman Truck Series debut. His smooth and confident single-lap run signalled that he was ready to compete at a high level.

While qualifying went according to plan, the race itself presented a far greater challenge. From the drop of the green flag, Andretti battled an extremely loose condition in his truck. Demonstrating a high level of control, he twice saved the TopLiner™ truck from near spins in the opening laps. However, midway through Stage 1, the handling issues finally caught up with him, and the truck snapped around for a solo spin.

In a display of composure beyond that of a series rookie, Andretti gathered the truck up on the apron and avoided significant damage, allowing him to continue without losing a lap. His ability to minimize the impact of the incident kept the TopLiner™ Toyota in contention and underscored his experience under pressure.

Despite the early adversity, Andretti fought back to finish Stage 1 in 26th position on the lead lap. Recognizing the need for adjustments, the TRICON Garage crew went to work. Through strategic changes during Stage 2, they tightened the truck’s handling, giving Andretti the stability he needed to begin his charge forward.

The improvements were evident almost immediately. Andretti steadily worked his way toward the top 20, ultimately closing Stage 2 in 22nd position and trending in the right direction. The combination of precise crew chief adjustments and Andretti’s adaptability behind the wheel began to unlock the speed that had been apparent in qualifying.

As the final stage unfolded, the TopLiner™ emblazoned contender continued to build performance. Through crafty strategy and showcasing pure pace, Andretti maneuvered the No. 5 truck through the field. With confidence growing each lap, he executed clean passes and maintained consistent speed, ultimately crossing the finish line in an impressive 12th-place position.

The result marked a significant achievement for both Andretti and TopLiner™. At a track where expectations were undefined, Andretti exceeded them all — delivering a performance that demonstrated speed, resilience, and race-day growth. His debut not only validated the team’s preparation but also established him as a driver to watch in the NASCAR Craftsman Truck Series paddock.

“Adam showed incredible determination and adaptability,” said TopLiner™ chief Claudio Burtin. “Qualifying P8 set the tone, and the way he rebounded from early challenges speaks volumes about his talent and professionalism. We’re extremely proud of the entire team’s effort.”

With momentum firmly on his side, Andretti now shifts focus to the Streets of St. Petersburg, where the road course layout is expected to play directly into his strengths as an accomplished road racer.

Building on a breakthrough debut at EchoPark Speedway, TopLiner™ are poised for even greater success in the races ahead.

How Diesel Tuning Improves Torque for Motorsport Use

By

Torque is literally why diesel engines should be in motorsport. While the gas engines are after horsepower at high RPM, a perfectly tuned diesel engine is capable of delivering a huge twisting force at low revs which is exactly what you need when you get out of a corner, climbing a steep trail, or launching off the line in a drag race. Diesel has an undeniable advantage from a physics perspective.

However, the maps of stock diesel tuning are basically compliance-oriented, not competition-oriented. Manufacturers are under pressure to meet emissions regulations, warranty issues, fuel economy goals, and also have to consider the vehicle’s drivability in a wide range of situations. Hence, they come up with a very cautious tune that still allows for a significant amount of the performance to be unused. To unlock this performance, one has to understand what tuning really changes and why those changes directly result in more usable torque on the track.

What ECM Tuning Actually Changes

The engine control module is responsible for governing all aspects that determine torque output, injection timing, fuel rail pressure, boost targets, torque limiters, and rev limits. When the car is in stock form, these parameters are set conservatively. A performance tune changes those conservative values to parameters that are optimized for maximum output, within the mechanical limits of your engine and supporting components.

Injection timing is by far the most impactful of all variables. Advancing timing causes fuel to be ignited earlier in the compression stroke, which means combustion pressure is acting on the piston for a longer time and with greater force. Even small timing advances can yield significant torque gains, however, if you push too far without the proper supporting upgrades you run the risk of damaging pistons and head gaskets under sustained load.

Fuel quantity per injection event is also a lever. More fuel means more energy is released per combustion cycle, which results directly in higher torque. This is the reason why fueling upgrades such as larger injectors, upgraded lift pumps, and dual CP3 setups, are required to be able to accompany aggressive tunes. The tune can command more fuel, but the hardware must be capable of delivering it consistently.

The Role of Torque Management in Stock Tunes

Factory tunes incorporate torque management strategies that limit power output in certain scenarios. These are mainly designed to keep the transmission, driveline, and engine safe from stress, but on the other hand, they also reduce the performance that you are actually paying for each time you accelerate.

Transmission torque limiters refer to a situation where the transmission is told to request less torque from the engine during gear changes and under certain throttle conditions to prevent clutch pack damage. If the transmission is built with upgraded clutch packs and a performance valve body, those limits are not necessary. A tuner who knows your complete build can eliminate or lift these limiters so that the engine produces what the driver is asking for.

Automatics in the diesel category also allow for tuning of shift points and shift firmness. In a racing or motorsport situation, firmer and quicker shifts are usually preferred in order to keep the engine in its power band. Stock programming puts the emphasis on smoothness and comfort, which is not what you want when you are racing.

Emissions Systems and Performance Tuning

Here is where the discussion gets down to earth for those who are into serious motorsport builds. So, the diesel emissions system or more exactly the EGR (exhaust gas recirculation) and DPF (diesel particulate filter), is what creates real performance constraints.

EGR recirculates the heated exhaust gas back into the intake thus lowering combustion temperature but obviously this also reduces power and generates soot. DPF basically is a filter that traps particulate matter and it has to be regularly burned off through the regeneration cycles which can be very unpredictable and troublesome during racing conditions.

Many competitive motorsport builds address this by going further than a tune alone. Combining ECM calibration with a diesel delete kit removes the EGR and DPF systems entirely, allowing the tune to operate without the constraints those systems impose. The result is cooler, denser intake charge temps, cleaner combustion, and elimination of the regeneration cycle that can cut power at the worst possible time.

It’s worth being clear that emissions deletions are not street-legal in most jurisdictions and are intended for closed-course competition use. Motorsport and off-road racing vehicles that run in sanctioned events on private land operate under different rules than road-registered vehicles. Understanding the legal context for your specific application matters before going down this path.

Torque Curve Shaping for Different Motorsport Applications

Not all forms of motorsport require the same torque delivery. For instance, a diesel drag truck eagerly desires a maximum torque right at the start, and it wants this to be maintained throughout the entire run. On the other hand, a desert racer is in need of a powerful mid-range response to the throttle when speeding through the rough parts of the track. A rock crawler, however, prefers the torque curve to be smooth and predictable at very low speeds, which is the area of most critical throttle modulation.

An expert diesel tuning technician is able to shape the torque curve so that it fits the application, rather than simply aiming at the highest peak figures. This means the tuner, for example, can control how fueling and boost level aggressively ramp up from idle, decide the location of peak torque in the RPM range, and determine how the engine behaves under partial throttle conditions. A dyno-optimized tune that results in a sharp peak at a very narrow RPM band may look very good in theory but it gives the worst performance in real race conditions, where the engine speed and load vary over a wide range.

Compound turbo systems also take this to a higher level. A proficient tuner is able to fine-tune the interaction between the two turbos in a small, over, large turbo configuration so that the resultant engine has an excellent low-RPM response, yet it can still develop substantial power at higher RPMs. 

Real-World Gains and Managing Expectations

For a stock, hardware diesel, the increase in torque through tuning is mostly between 15 25% if the performance tune is a conservative street one. With a built engine, upgraded injectors, a bigger turbo, and supporting modifications, a full, build tune can elevate the torque figures by 60, 80% or even more in comparison to factory numbers. The maximum limit is mostly the mechanical strength of your engine internals, rods, and head fasteners.

The aspect where reliability during sustained motorsport use separates the quality of tuning is entirely up to the person writing it. Everyone can make a tune that puts up huge numbers on a dyno for a couple of pulls. The tune that lasts through a 500-mile desert race or a full day of competitive rock crawling is totally different. The heat cycles, sustained load, and vibration environment of off-road racing expose every component to stress in a way that is not typical for either a street or a drag strip application.

A difference can be seen in the tunes that a person who has raced diesel trucks writes and those that are primarily for street performance. Major differences in racing are revealed exclusively through conditions.

MOORESVILLE, N.C. (February 23, 2026) – TRD U.S.A. (Toyota Racing Development) announced a long-term commitment to third-generation driver Keelan Harvick, who will continue his development through pavement opportunities as a part of the TOYOTA RACING family. During the 2026 motorsports season, Harvick will partner with RACKLEY W.A.R. and Kevin Harvick, Inc. to compete in dozens of late model races nationwide, piloting the No. 62 Toyota Camry with ExxonMobil serving as primary sponsor for several of those events.

“I’m really grateful to have this kind of opportunity with Toyota Racing Development,” said Harvick. “To have their support and be able to represent ExxonMobil, it doesn’t get much better. I’m still getting experience, but it’s going to be a privilege to be part of the TRD program and learn from the other drivers.”

The 13-year-old continues to make history with his success across multiple racing series. In December, Harvick became the youngest-ever winner of the Snowflake 125 at Five Flags Speedway. He followed up with a victory in Florence Motor Speedway’s Icebreaker earlier this month, crowning him the youngest winner of that event while also earning his first career LMSC victory. The 2024 INEX Young Lions National Champion made the successful transition from Legends to Late Models as he won four zMAX CARS Tour Pro Late Model events and two CARS Tour West Pro Late Model Series races in 2025, becoming the first driver to win PLM events in both series in the same season.

Big Names, Big Field for Mazda MX-5 Cup at St. Pete

By
Official Release
-

ST. PETERSBURG, Fla (Feb. 23, 2026) – After a record-breaking grid size to open the season, Whelen Mazda MX-5 Cup presented by Michelin is headed to the streets of St. Petersburg, Florida with 42 cars. Two of those Mazda MX-5 Cup machines will be piloted by world-renowned drivers Sebastien Bourdais (No. 38 McCumbee McAleer Racing) and Earl Bamber (No. 21 Hendricks Motorsports), who are making guest appearances in Rounds Three and Four.

The 1.8-mile temporary street circuit is a favorite for many Whelen Mazda MX-5 Cup drivers. Despite being made up of various roads and runways along the Port of St. Petersburg, the track still has a good flow to it, with several decent passing areas. The sun is always shining, and the atmosphere feels like a city festival for the traditional INDYCAR season opening weekend.

Four drivers on the grid know what it feels like to win at St. Pete: Jared Thomas (No. 96 JTR Motorsports Engineering), Gresham Wagner (No. 5 JTR Motorsports Engineering), Tyler Gonzalez (No. 57 BSI Racing) and Bourdais. Of course, Bourdais’ two prior victories came in an IndyCar rather than a Mazda MX-5.

The Frenchman who has called the Bay area home since 2003 is venturing into MX-5 Cup in the name of charity. To raise money for Karts4Kids, donors can put their name on the car Bourdais is set to race at St. Pete.

What of the other drivers with St. Pete-winning experience? Well, none of them had a great start to the season at Daytona. In fact, all three had a DNF in one of the two races and Gonzalez was the only one who made a trip to the podium. Now, all three need to bank major points at St. Pete to regain momentum toward the $250,000 prize from Mazda that goes to the season champion.

Thomas has twice won MX-5 Cup races at St. Pete, the most recent being last year. Winning Race 1 and finishing third in Race 2 propelled him to the point lead leaving Florida. In contrast, Wagner did not compete in last year’s event at St. Pete, but he was part of a classic Mazda MX-5 Cup moment in 2023, when he drag-raced Connor Zilisch out of the final turn and to the line, winning by 0.021-second.

For Gonzalez, St. Pete had been a cruel track until last year, when he won Race 2. To that point he’d never even been in the top five at the street circuit.

All three of these drivers have an important thing in common; experience, and it’s going to take experience to navigate the narrow, concrete-lined street circuit.

“I think it takes a good setup and a lot of consistent driving to have a chance to win at St. Pete,” Wagner said. “In terms of making lap time, the walls aren’t much of a consideration for me, and I’m sure there’s a lot of quick drivers that don’t let it get in the way of their driving.

“Really, the track becomes tight and punishing when it comes to racing other drivers, both when defending and overtaking. I think that’s what stands out the most — the wheel-to-wheel racing becomes that much more aggressive, with much less margin for error. You really have to think a lot more about the moves you’re going to make at St. Pete, because in plenty of spots, there aren’t many options besides hitting the wall.

“I think the drivers that come out in front usually have done a great job of managing their aggressiveness, and not getting too caught up in the moment. More than most tracks, you have to give a bit more consideration and margin to every decision you make.”

The big winner coming into St. Pete is Justin Adakonis (No. 23 McCumbee McAleer Racing). He leads the points after scoring a career-best finish of second in Race 1 and backing it up with a 10th-place finish in Race 2. The sophomore has been on a streak of strong finishes since VIRginia International Raceway last August.

Of the three current MX-5 Cup Shootout Scholarship recipients, Ethan Lampe (No. 31 Advanced Autosports) had the best results at Daytona and arrives in St. Pete 11th in points.

Then there’s the Kiwi wildcard: Bamber. He’s never raced the St. Pete street course, but he has raced MX-5 Cup before, at Martinsville, an oval. That race was going great until contact took him out in the second half. Can he duplicate his performance this week on a street circuit? More importantly, which of the pros will finish higher: Bamber or Bourdais?

Watch and find out the answers when Race 1 goes green at 7:30am ET on Saturday, February 28 and again on Sunday, March 1, when Race 2 gets going at 4pm ET. Both races will be streamed live on the IMSA and RACER YouTube channels.

About: The Whelen Mazda MX-5 Cup presented by Michelin is the signature spec series for Mazda Motorsports. The series has been operated by Andersen Promotions since 2017 and is currently sanctioned by IMSA. Mazda-powered grassroots champions can earn Mazda scholarships for this pro-level series. The Whelen Mazda MX-5 Cup awards more than $1 million in prizes and scholarships.

INDYCAR Officiating Ready for 2026 Season Opener in St. Petersburg

By
Official Release
-

INDIANAPOLIS (Monday, Feb. 23, 2026) – The Independent Officiating Board (IOB) remains focused on establishing and launching INDYCAR Officiating to clearly define operational and governance separation and transparency as preparations continue for the upcoming 2026 NTT INDYCAR SERIES and INDY NXT by Firestone seasons.

In the last few months, the IOB, with chairman Raj Nair, secretary and treasurer Ray Evernham and FIA appointee Ronan Morgan, has been diligent in the work needed to arrive to this point of the year, which has included the following:

  • Establishment of the not-for-profit INDYCAR Officiating Inc. corporation
  • Finalizing the 2026 INDYCAR Officiating budget
  • Reviewed INDYCAR’s established processes and personnel
  • Determined a need for additional experienced personnel for the tech team
  • Determined the need for a separate INDY NXT race director
  • Reviewed the steward positions and determined to make no changes

“The board has been meticulous and thorough in our review of INDYCAR’s officiating process and procedures,” board chairman Nair said. “While we are pleased with the early achievements, there is plenty of work still to do. Among our major goals is to implement a more detailed transparency reporting structure to teams – related to technical and race infractions – as well as establishing consistency of rule implementation and enforcement. As a collective, we are confident in the results our team will achieve over the season.”

The IOB also continues to interview candidates to find the perfect fit for the roles and responsibilities of the managing director of officiating (MDO). As the process of identifying the ideal person continues and until that hire is announced, the board plans to oversee general independent officiating operations.

“One of the clear takeaways as we analyzed INDYCAR officiating and operations has been that INDYCAR already greatly benefits from the knowledgeable and professional personnel in race control and technical inspection,” said board member Evernham. “With that, combined with the expertise that the board brings, we are going to work with the current team members of each but will add additional resources and support.”

The three members of the IOB will attend and provide oversight for INDYCAR Officiating at the season opener on the Streets of St. Petersburg and will then share responsibilities over the initial races until the MDO can be secured.

Kyle Novak will continue as the race director and vice president of INDYCAR Officiating. Novak has served as the sport’s race director since the 2018 season and leads race control and circuit safety development. He is responsible for developing and enforcing NTT INDYCAR SERIES and INDY NXT by Firestone competition regulations.

Also an attorney, Novak serves as one of 36 judges on the FIA Courts and hears cases as a member of the FIA International Tribunal and International Court of Appeal.

On the technical side, the IOB has determined that Kevin “Rocket” Blanch will continue as the INDYCAR Officiating’s technical director. Blanch will oversee the technical inspection process and will provide technical oversight and ensure compliance of aerodynamic and chassis regulations.

Blanch joined INDYCAR in 2003 after serving six-plus seasons with Panther Racing, where he served as the team’s crew chief. During his tenure there, the team won two INDYCAR SERIES championships and earned 11 victories and five pole positions.

Arie Luyendyk and Max Papis will continue to lend their expertise as chief stewards for INDYCAR Officiating. Luyendyk, who has seven INDYCAR SERIES race wins – including two Indianapolis 500 victories, and Papis, a three-time INDYCAR SERIES race winner, have served as series stewards since their original appointment in 2016. Both officials are stationed in race control and monitor on-track sessions, review incidents for rule violations and enforce penalties.

Working with Blanch, the IOB has added Nick Allen as a technical inspection manager for the NTT INDYCAR SERIES. Allen brings over 20 years of experience as an INDYCAR race team mechanic and chief mechanic. In the coming weeks, INDYCAR Officiating will add a tech inspection manager for INDY NXT and, working with Novak, a dedicated INDY NXT race director.

“The officiating in INDYCAR is not broken; in fact, racing series around the world could learn from its procedures and operation,” said board member Morgan. “At this point, our opinion is that independent INDYCAR Officiating should be framed as a sensible evolution when it comes to general process. By providing and overseeing additional support, transparency and added separation between officials and series management, we firmly believe that INDYCAR Officiating is primed to be successfully implemented for the 2026 season.”

Coverage of the Firestone Grand Prix of St. Petersburg, round one of the 18-race 2026 NTT INDYCAR SERIES championship, begins at noon ET Sunday, March 1 on FOX, FOX Deportes, FOX One and the FOX Sports app. Coverage will also be provided by the INDYCAR Radio Network via SiriusXM Channel 2018 and the INDYCAR App powered by NTT DATA.

“The 2026 season is a milestone moment for NHRA Pro Mod Drag Racing Series, which continues to be one of the most exciting and unpredictable categories in drag racing,” NHRA Senior Vice President Evan Jonat said. “We’re proud to celebrate this anniversary across all 11 events this year and offer fans free coverage on the NHRA YouTube page.

The Complete Guide to Workshop Manuals: What Every Car Owner Should Know

Why the Right Manual Makes All the Difference in Your DIY Repairs

Whether you’re a weekend warrior tackling your first oil change or a seasoned DIY mechanic rebuilding an engine, having the right workshop manual can mean the difference between a successful repair and a costly mistake. In this comprehensive guide, we’ll explore everything you need to know about workshop manuals—and why they’re essential for anyone serious about vehicle maintenance.

What Is a Workshop Manual?

A workshop manual—also called a factory service manual or OEM (Original Equipment Manufacturer) repair manual—is the official technical documentation created by the vehicle manufacturer. Unlike generic repair guides you might find at an auto parts store, these manuals contain the exact procedures, specifications, and torque values that factory-trained technicians use in dealership service centers.

Think of it as the difference between a recipe from a professional chef versus one from the back of a cereal box. Both might help you make breakfast, but one gives you significantly more detail, precision, and professional results.

Workshop Manual vs. Repair Manual: Understanding the Difference

Many car owners use these terms interchangeably, but there are important distinctions that can impact your repair success. Here’s a detailed comparison:

Manual

When Do You Need a Workshop Manual?

Workshop Manual Recommended For:

  • Engine rebuilds or internal engine work
  • Transmission repairs and overhauls
  • Electrical diagnostics and complex wiring issues
  • Suspension geometry adjustments and alignments
  • Any job requiring precise torque specifications
  • Hybrid or EV high-voltage system work
  • Advanced diagnostic procedures

Aftermarket Manual May Be Sufficient For:

  • Oil changes and filter replacements
  • Brake pad replacement
  • Battery replacement
  • Basic fluid checks and top-offs
  • Simple maintenance tasks

What’s Inside a Professional Workshop Manual?

A comprehensive workshop manual typically includes these detailed sections:

  • General Information – Vehicle identification, specifications, maintenance schedules, special tool requirements
  • Engine Mechanical – Complete disassembly/assembly procedures, timing procedures, head gasket replacement
  • Fuel & Emissions Systems – Fuel injection diagnostics, sensor locations and testing procedures
  • Electrical Systems – Complete wiring diagrams, diagnostic trouble codes, circuit testing
  • Transmission & Drivetrain – Manual/automatic transmission procedures, differential service
  • Steering & Suspension – Alignment specifications, component replacement procedures
  • Braking Systems – Brake bleeding procedures, ABS diagnostics, pad replacement
  • Body & Interior – Trim panel removal, airbag system precautions, interior service

Pro Tips for Using Workshop Manuals Effectively

Read the Entire Procedure First: Before starting any repair, read through the complete procedure to understand required tools, time estimates, and step order.

Note the Torque Specifications: Write down all torque specs before you pick up a wrench. This prevents stopping mid-job to check values.

Pay Attention to Warnings: Safety warnings and cautions aren’t suggestions—they exist for critical safety reasons and to prevent component damage.

Cross-Reference Part Numbers: Use the manual’s part numbers to ensure you’re ordering exactly the right components for your specific vehicle.

Document Your Work: Take photos during disassembly. Your manual shows what things should look like, but photos show what YOUR vehicle looked like.

Use the Wiring Diagrams: Learn to read wiring diagrams—they’re invaluable for electrical diagnostics and can save hours of troubleshooting.

Common Mistakes When Working Without a Manual

Working without the proper manual—or using generic instructions instead of manufacturer specifications—can lead to these costly errors:

  • Incorrect Torque Values — Stripped threads, loose components that vibrate apart, or failed repairs that need to be redone.
  • Wrong Fluid Types — Using incorrect transmission fluid or coolant can cause seal deterioration and expensive damage.
  • Missed Critical Steps — Forgetting to bleed brakes properly, not resetting ECU adaptations, or skipping safety procedures.
  • Electrical System Damage — Blown fuses, damaged control modules, or airbag system problems from improper procedures.
  • Incorrect Assembly Order — Reassembling components in the wrong sequence, leading to parts that don’t fit or function properly.

Real-World Impact: Why Specifications Matter

Consider a simple head bolt torque specification. A generic manual might say “torque to 65 ft-lbs.” But a factory workshop manual provides the complete procedure: “Torque in sequence to 22 ft-lbs, then 45 ft-lbs, then an additional 90 degrees, then a final 45 degrees.” 

Following the generic instruction could result in a blown head gasket within months. Following the factory procedure ensures proper clamping force and gasket seal for years of reliable operation. That’s the difference a proper workshop manual makes.

How to Choose the Right Workshop Manual for Your Vehicle

Match Your Vehicle Type:

  • Domestic Vehicles (Ford, GM, Chrysler) — OEM workshop manuals are widely available and affordable. Essential for modern vehicles with complex electronics.
  • Japanese Vehicles (Toyota, Honda, Nissan) — Excellent OEM documentation available. Japanese manufacturers produce particularly detailed electrical diagrams.
  • German Vehicles (BMW, Mercedes, Audi, VW) — OEM manuals are essential due to complex electronics and proprietary systems. Generic manuals often lack critical information.
  • Classic & Vintage Cars — Original factory manuals are preferred and often available as reprints. Period-correct procedures and specifications are crucial.
  • Hybrid & Electric Vehicles — OEM manuals are mandatory—these contain critical high-voltage safety procedures that aftermarket manuals cannot replicate.

The Bottom Line: Workshop Manuals as an Investment

Whether you’re maintaining a daily driver, working on a project car, or restoring a classic, having access to accurate technical information is absolutely essential. A quality workshop manual pays for itself with the very first repair you complete correctly—or the first costly mistake you avoid.

Consider this: the average shop labor rate is $100-150 per hour. A workshop manual typically costs $50-200. If it saves you just one or two hours of labor on a single repair—or prevents one mistake—it has already paid for itself many times over.

For DIY mechanics serious about working on their vehicles, investing in a proper workshop manual isn’t an expense—it’s an investment in doing the job right the first time, every time.

Frequently Asked Questions

Q: What’s the difference between a workshop manual and a Haynes manual?

A: A workshop manual is the official factory documentation created by the vehicle manufacturer, containing exact specifications and complete procedures. Haynes manuals are aftermarket publications that provide good overviews but with less technical detail and generic specifications.

Q: Are workshop manuals worth the money?

A: Absolutely. The cost ($50-200) is typically less than one hour of shop labor. Having accurate specifications prevents costly mistakes, saves time, and ensures repairs are done correctly the first time.

Q: Do I need the workshop manual for my specific year and model?

A: Yes, this is crucial. Specifications, procedures, and even component designs can vary significantly between model years. Always match the manual exactly to your vehicle’s year, make, and model.

Q: What format should I get—PDF or printed?

A: PDF manuals offer searchability, portability (view on a tablet in your garage), and instant access. Printed manuals don’t require batteries or screen brightness. Many mechanics prefer PDF for the search function alone.

Q: Where can I find reliable workshop manuals?

A: Reputable sources like WorkshopManuals.com offer OEM and OEM-equivalent manuals for most makes and models, with instant PDF downloads and verified accuracy.
