IndyCar to use more powerful engines in 2021

Leave a comment

The Verizon IndyCar Series will make use of a new engine formula beginning with the 2021 season.

The updated formula increases the size of the current V-6 twin-turbo engines to 2.4 liters – they’re currently 2.2 liters in displacement – with over 900 horsepower expected to be available when push-to-pass is engaged, and engines will continue with a maximum RPM range of 12,000.

The engine formula is expected to be in place from 2021 through 2026.

Jay Frye, INDYCAR president of competition and operations, explained the decision for more displacement and an increase of power is in response to driver feedback.

“Our drivers have been asking for more horsepower and thanks to the hard work of Chevrolet, Honda and the INDYCAR engine group, they’re going to get it,” Frye asserted in an announcement.

Officials from both Honda and Chevrolet detailed that the engine regulations will nicely align with their marketing and performance goals.

Said Jim Campbell, U.S. vice president of performance vehicles and motorsports for General Motors, “The 2.4-liter, twin-turbo V-6 engine formula that will be introduced for the 2021 season will continue to showcase relevant technologies that we incorporate in our production engines. The opportunity to transfer learnings in performance, reliability and efficiency between the racetrack and the showroom is very important to Chevrolet.”

Added Art St. Cyr, president of Honda Performance Development, “The new INDYCAR engine formula should be exciting for the fans and an interesting technical challenge for Honda Performance Development. While the overall architecture remains similar to the current engine, the increased displacement will bring many changes, including a notable increase in power that should please all fans of the sport. In addition, it provides our designers and engineers with an opportunity for significant development, which is a challenge we welcome at Honda.”

Testing of the new engine platform will begin in the summer of 2020.

IMSA’s Bill Auberlen joins NASCAR America to discuss this weekend’s race at Lime Rock

Leave a comment

Turner Motorsport GTD driver Bill Auberlen joined NBC Sports’ Marty Snyder on NASCAR America Presents the Motorsports Hour Thursday to discuss a variety of topics, including Saturday’s IMSA WeatherTech Sports Car Championship race at Lime Rock Park.

Auberlen, alongside co-driver Robby Foley, enters Lime Rock with a great amount of momentum after finishing on the GTD podium at Watkins Glen and taking the GTD class honors in the most recent IMSA race at Canadian Tire Motorsports Park.

There’s also an extra incentive for the duo to win this weekend as well, as Auberlen is one win away from tying Scott Pruett for the most IMSA victories all-time.

Both drivers will have to be on their A-game this weekend, however, as Auberlen stated that Lime Rock is one of the tougher circuits on the IMSA calendar and compared the 1.5-mile Connecticut road course to a short track.

“It’s what we call the bullring of our season,” Auberlen said. “It is a 54-second lap and we’re going to go around it a million times before the end of the day. It’s going to be a hot one, and I think whoever survives this is going to be on the podium.”

Luckily for the GTD and GTLM teams, with no Protoype and LMP2 entries competing at Lime Rock this weekend, the worry of having to yield to entries from the faster classes is gone.

“These Protoypes are so fast now, that interacting with them, you can’t imagine,” Auberlen said. “We have radars in our car that can alert us when they are coming.

“They get on you so fast that if you’re not always looking or something is not telling you they’re coming, you could have a problem and catch into them. That’s gone. Now it’s going to be focus-forward. You’re going to be focused on everything ahead of you. You got GLTM in there at the same time, but they’re virtually the same speed as us – just a little bit faster.

“It’s going to be nice. When you stand on that podium you might be able to go for an overall victory.”
