NASCAR and manufacturers have discussed the hybridization of future cars but one manufacturer executive said it won’t happen soon.

“Relative to hybridization and electrification, quite simply, it’s not a question of if, it’s a question of how and when,” David Wilson, president of Toyota Racing Development said Thursday morning on SiriusXM NASCAR Radio. “A hybrid type of strategy is absolutely something that we’re looking at.

“Candidly, it won’t be something that we see as early as ’21. That’s, realistically, a little further down the road.”

NASCAR Vice Chairman Mike Helton said May 20 on the Dale Jr. Download that a key to the Gen 7 car — expected to debut in 2021 — would be to “make room for what might happen next. Not in the short-term, but if the automobile industry and the racing industry go down the road with some type of electrification, the chassis should have room for that. In the motor component, whatever evolution we go to in the next generation of power plants for the cars … we have the opportunity with a clean sheet of paper to build a chassis that can accommodate that easily without having to tear a car apart.”

Brad Keselowski wrote an essay last May titled: It’s time: The NASCAR hybrid. Keselowski wrote: “Not only am I sure that hybrids are the future of NASCAR — I believe it’s essential to the success of the sport that we embrace hybrid technology as soon as possible.”

Hybrids have become more important for manufacturers, Wilson said on “The Morning Drive” on Thursday.

“You look across the motorsports landscape, you’re seeing hybridization and electrification everywhere you look,” he said. “That again is simply a reflection of the automotive culture on a global basis. Today, Toyota has eight different hybrid vehicles in their lineup.”

Jim Campbell, Chevrolet’s U.S. Vice President of Performance Vehicles and Motorsports, also was on “The Morning Drive” on Thursday and expressed the value of the Gen 7 car being able to incorporate hybrid elements in the future.

“I think Gen 7 gives an opportunity to bring more relevant elements of the car and the technology to what we’re selling in the showroom or what we’ll be selling more of in the future,” Campbell said. “Along with that is the ability of if we do that have an opportunity to attract more (manufacturers). So it all does really fit together. There’s still much work going on with the Gen 7.

“In terms of hybrid, I will tell you that every series we’re involved in, every single series Chevy is involved in … is looking at what is the opportunity to package protect or what are the options to include some element of hybridization. That’s really where it is right now. It’s in a discussion phrase. It hasn’t been locked down.”

In regards to hybridization coming to NASCAR, Wilson said on SiriusXM: “It is an inevitability from our perspective.”

Before the season, Mark Rushbrook, global director of Ford Performance, said of hybrids: “As we change road cars, we’re not going directly from an internal combustion engine to electric. We’ll have hybrids along the way. I don’t know NASCAR needs to go full electric.

“Even if you continue racing the internal combustion engine, we get a ton of benefit from that and connection with the fans. The ability to put the hybrid in when the time is ready, that’ll continue to connect as fans’ cars and trucks go hybrid.”
