IndyCar: Chevrolet aero kits unveiled (VIDEO)

INDIANAPOLIS – We have evidence that the new IndyCar aero kits not only exist but are being publicly revealed later today here in Indianapolis.

GM has posted the release up to its website. Here is the release, below:

Chevrolet-powered racecars in the 2015 Verizon IndyCar Series will feature Chevrolet-developed aero packages.

Chevrolet introduced the road course/short oval body design today at the Indianapolis Motor Speedway. It is distinguished from the previous racecar with new front wing elements, sculpted side pods and a new rear wing.

A speedway configuration for the aero kit, designed for high-speed ovals, will be introduced ahead of its competitive debut at Indianapolis in May.

“This is an important milestone in Chevrolet’s involvement in IndyCar racing,” said Jim Campbell, General Motors U.S. vice president of Performance Vehicles and Motorsports. “We focused on developing an aerodynamic package that delivers an optimal balance of downforce and drag, along with integrated engine performance. It’s a total performance package.”

The new Chevy road course aero configuration delivers greater aerodynamic performance than the previous design.

“This new aero kit provides Chevrolet drivers the capability to enter and exit corners faster, while maintaining high speeds on the straights,” said Chris Berube, Chevrolet IndyCar program manager.

Development of Chevrolet’s new IndyCar aero package consisted of nine key phases:

  • Conducted baseline analysis of the “DW12” racecar aerodynamics
  • Established clear design goals for the new aero kit, which included making the most of downforce, drag and engine performance
  • Developed design concepts using computer-aided design (CAD)
  • Analyzed structural properties, using finite element analysis (FEA)
  • Simulated aerodynamic properties using computational fluid dynamics (CFD)
  • Produced test parts using rapid prototyping processes, such as 3D printing
  • Conducted testing of a 50-percent scale model in a rolling–road wind tunnel
  • Conducted testing of a full-scale racecar in a rolling-road wind tunnel
  • Conducted track testing of prototype aero kit on select race tracks, including Homestead-Miami Speedway, Circuit of The Americas (Austin, Texas), Texas Motor Speedway and Phoenix International Raceway.

“We took a clean-sheet approach to the aero kit, delivering an optimized and efficient design that should really give our Chevrolet teams an edge,” said Berube.

The road course configuration’s changes over the 2014 DW12 aero package are easily identified by major components, including:

  • Front wing that features new pedestal-mounted “front uppers” toward the outer edges
  • New sculpted “wheel wedges” in front of the rear tires
  • An engine cover and side pods that have more compact shapes, achieved through a revised turbocharger and exhaust system layout
  • New larger rear bumper pods
  • A multi-element upper rear wing, along with louvered end plates.

The all-new Chevrolet racecars will compete for the first time on March 29 at the Firestone Grand Prix of St. Petersburg, Fla. .

X44 Racing win 2022 Extreme E championship as Abt Cupra score first race victory

Abt Cupra Racing’s Nasser Al-Attiyah and Klara Andersson scored their first win in the Extreme E Energy X Prix in the 2022 finale in Uruguay as Lewis Hamilton’s X44 Vida Carbon Racing drivers Sebastien Loeb and Cristina Gutierrez survived a chaotic finale to edge the 2021 champion Rosberg X Prix team of Johan Kristoffersson and Mikhaela Ahlin-Kottulinsky, by two points.

“There are so many emotions,” Andersson said in Extreme E’s coverage. “I’ve been waiting for this for so long. In my second race, first full weekend to be at the top of the podium: it’s big.”

Andersson was behind the wheel at the finish.

Rosberg Racing entered the event with a 17-point advantage over X44, but the standings were close enough that four teams remained in contention in Round 5.

“It’s a crucial weekend for us,” Loeb said in Extreme E’s coverage prior to the race. “We are not in the best position to win the championship, but the only thing we can do is try to win the race and score as many points as possible.”

The top two title contenders each crashed in qualification and were relegated to the Crazy Race, Extreme E’s version of the Last Chance Qualifier (LCQ). For the moment, they had the steepest hill to climb, but then the other two championship contending teams, Chip Ganassi Racing and Acciona Sainz Racing failed to advance from their heats.

Only one team advances from the Crazy Race, so the X44 drivers were in a must-win situation to simply keep hope alive.

Ahlin-Kottulinsky and Gutierrez ran wheel to wheel into the first turn at the start of the LCQ.

The Rosberg racer experienced crash damage in that turn that damaged her front steering, but managed to limp back to the pits at the end of her two-lap stint. The team attempted to fix the steering, but incurred a penalty for having too many mechanics in the pit area.

Meanwhile, Gutierrez took the early lead, but knew she would need to sit through a five-second penalty for an incident earlier in the weekend. The female half of the gender equal pair erased the penalty by entering the Switch Zone with a five-second lead before turning the car over to Loeb.

That was all the nine-time World Rally Championship titlist needed to give him the advantage needed to win the Crazy Race.

But the championship was not over yet. X44 Racing needed to finish third or better in the five-car finale to earn enough points for the title and after advancing from the LCQ, they were forced to take the worst grid position.

A chaotic start to the Finale saw Loeb run as high the lead and low as fourth after getting pushed off course during his first lap. And that is how he entered to Switch Zone.

On her first lap, Gutierrez slammed into Molly Taylor. With one lap remaining, X44 and Gutierrez were still in fourth and the title hope was quickly evaporating, but it was announced halfway through the lap that the third-running Andretti United team would suffer a penalty for a Switch Zone infraction. The seven-second deduction for Timmy Hansen braking too late in the zone made the difference in the title.

Coming off a disappointing Copper X Prix when Tanner Foust and Emma Gilmour crossed under the checkers first, but were relegated to fifth by penalty, the McLaren pair scored their first podium of the season in second.
