Chevrolet Indy 500 aero kit revealed

The public now has their first look at Chevy's superspeedway aero kit.

Ahead of Sunday’s Opening Day open test for the Verizon IndyCar Series at Indianapolis Motor Speedway (IMS), site of the 99th Indianapolis 500 on May 24, Chevrolet Racing revealed the specifications of its Super Speedway aero kit, just a few days after competitor Honda Performance Development, whose similar kit took a bow earlier in the week.

Chevrolet, whose road and street course aero kit has won three of the four races held thus far in the short season, has features it developed specifically for racing at Indy. Chevrolet’s two aero kits were developed side by side but the Super Speedway kit, made for ovals in excess of a mile in length - emphasizes the low-drag attributes that allow cars to speed to more than 230-mph on the iconic IMS 2.5-mile, near-flat oval.

“With the speedway configuration, the emphasis is on reducing aerodynamic drag for greater speed, while maintaining sufficient downforce,” explained Chris Berube, Chevrolet’s INDYCAR program manager. “Innovative designs were used to develop the right combination of downforce and drag, along with engine performance” that is unique to the Speedway.

A detailed look

The front wing on Chevrolet’s Super Speedway aero kit features a unique mainplane surface contour. It serves dual purposes where the inboard section directs air to the radiator inlets to enhance engine cooling, while the outboard section creates airflow around the front tire to minimize drag, Chevrolet stated.

The engine cover and side pods are shared with the road course model, but they feature close-out panels to their trailing edges that are intended to reduce drag. Louvers in the side pods provide added cooling benefits and clean airflow to the rear of the car, all of which delivers a higher level of diffuser and rear wing efficiency.

The wheel wedge configuration for this aero kit is fully adjustable, Chevrolet said. It provides various levels of downforce and efficiency to meet Indy’s ever-changing track conditions, which can force adjustments throughout the 500-mile, 200-lap race on the final Sunday in May.

Chevrolet’s rear bumper pods and its wheel wedges were designed as an integrated solution to reduce vehicle drag, the manufacturer touted. Finally, Chevrolet opted for a high-efficiency upper rear wing that will be unique to the Indianapolis 500. It features low-mass rear wing pillars and a low-mass rear mainplane.

Sunday test at IMS

The Opening Day open test scheduled for May 3 allows Chevrolet and competing Honda teams a first opportunity to test together with the homologated pieces of their Super Speedway aero kit modifications on the Brickyard oval. Many stands and vista mounds will be open to the public and the pomp of opening day will be observed with a ribbon cutting ceremony featuring honorary starter and racing enthusiast, Indianapolis mayor Greg Ballard.

Indy car veterans may test between 9:30-10:45AM on Sunday, while rookies and those needing refresher testing will be on-track from 10:45-noon. All-skate practice runs from 1-5PM.
