2 Comments

Chevrolet has now released its super speedway manufacturer aero kit, after Honda released its on Thursday.

See the full release below.

Chevrolet introduced its speedway aero kit to be used on high-speed ovals in the 2015 Verizon IndyCar Series – including features developed exclusively for running the Indianapolis 500.

The speedway configuration, which was developed in conjunction with the road course configuration, emphasizes the low-drag attributes that enable Chevrolet race cars to achieve speeds of more than 230 mph at the Indianapolis Motor Speedway’s famous 2.5-mile oval.

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

Highlights of the new design include:

Front wing

  • Unique mainplane surface contour serves 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 to minimize drag.

Engine cover and side pods

  • The engine cover and side pods are shared with the road course configuration, but are optimized in their speedway configuration by adding close out panels to their trailing edges to reduce drag.
  • Louvers in the side pods provide cooling benefits and clean airflow to the rear of the car, delivering higher levels of diffuser and rear wing efficiency.
  • The wheel wedge configuration is fully adjustable, providing various levels of downforce and efficiency to meet changing track conditions.

Rear bumper pods

  • The rear bumper pods and wheel wedges were designed as an integrated solution to reduce vehicle drag.

Rear wing

  • A high-efficiency upper rear wing, unique for the Indy 500, features low-mass rear wing pillars and a low-mass rear mainplane.

Chevrolet race teams will compete with the road course aero kit on May 9 for the Angie’s List Grand Prix of Indianapolis, on Indy’s infield road course, before converting their cars to the speedway aero kit for the Indianapolis 500 on May 24.

Zach Veach will be leaving his Andretti Autosport ride with three races remaining in the season, choosing to explore options after the decision was made he wouldn’t return for 2021.

In a Wednesday release, Andretti Autosport said a replacement driver for the No. 26 Dallara-Honda would be named in the coming days. The NTT IndyCar Series will race Oct. 2-3 at the Indianapolis Motor Speedway road course and then conclude the season Oct. 25 on the streets of St. Petersburg, Florida.

Veach was ranked 11th in the points standings through 11 races of his third season with Andretti. Since a fourth in the June 6 season opener at Texas Motor Speedway, he hadn’t finished higher than 14th.

“The decision was made that I will not be returning in 2021 with Andretti Autosport in the No. 26 Gainbridge car,” Veach said in the Andretti release. “This, along with knowing that limited testing exists for teams due to COVID, have led me to the decision to step out of the car for the remainder of the 2020 IndyCar season. I am doing this to allow the team to have time with other drivers as they prepare for 2021, and so that I can also explore my own 2021 options.

“This is the hardest decision I have ever made, but to me, racing is about family, and it is my belief that you take care of your family. Andretti Autosport is my family and I feel this is what is best to help us all reach the next step. I will forever be grateful to Michael and the team for all of their support over the years. I would not be where I am today if it wasn’t for a relationship that started many years ago with Road to Indy. I will also be forever grateful to Dan Towriss for his friendship and for the opportunity he and Gainbridge have given me.

“My love for this sport and the people involved is unmeasurable, and I look forward to continuing to be amongst the racing world and fans in 2021.”

Said team owner Michael Andretti: “We first welcomed Zach to the Andretti team back in his USF2000 days and have enjoyed watching him grow and evolve as a racer, and a person. His decision to allow us to use the last few races to explore our 2021 options shows the measure of his character.

“Zach has always placed team and family first, and we’re very happy to have had him as part of ours for so many years. We wish him the best in whatever 2021 may bring and will always consider him a friend.”

Andretti fields five full-time cars for Veach, Alexander Rossi, Ryan Hunter-Reay, Marco Andretti and Colton Herta.

It also has fielded James Hinchcliffe in three races this season.
