Over the course of the weekend, Chevrolet unveiled their brand new superspeedway aerodynamic kit that combines a reduction of drag to increase speed while maintaining a significant amount of downforce.
“Innovative designs were used to develop the right combination of downforce and drag, along with the engine performance,” Chevrolet IndyCar Program Manager Chris Berube said.
The new kit combines what they learned from their road/street course and short oval configuration and what they learned about superspeedway aerodynamics.
“Sidepods and the engine cover carry over, and they optimized for Indianapolis efficiency targets,” Chevrolet Racing Chief Aerodynalisist Arron Melvin said. “The wheel wedge is a carry over, although different add-ons are used with the wedge.”
The wheel wedge configuration is adjustable, providing various levels of downforce while being designed to reduce drag. The low-mass rear wing plane and pillar will be unique for the Indianapolis 500.
On the front wing, the surface will serve two purposes – the inboard section directs air to the radiator inlets to enhance engine cooling, while the outboard section creates airflow around the front tire.
“Downforce contribution required from rear wing is generally reduced compared to the Dallara IR-12 aerodynamics,” Melvin added. “Design is more efficient, event at the same wing force level. Lightweight design was important to us.”
The new kit proved to be fast as Chevrolet driver Juan Pablo Montoya led the first day at testing at Indianapolis Motor Speedway on Sunday.
