Corvette commits to V8 long term as EV still "science fiction"

“But when you drive an E-Ray, you just fire it up and drive it. It's just a hybrid. It charges the battery for you. It does everything. If you want to override and make it charge the battery faster, there's a button for that. But other than that, that's pretty much it, and keep it simple, keep it usable.”

He added that if manufacturers were given “some kind of credit from the regulators” in order to hit a certain electric-only range, “then I would consider [PHEV] for this version of the car”.

Looking forward, Roma said that when it does eventually come, the electric Corvette will need to be “engaging” instead of just fast because 0-62mph times are becoming a “meaningless metric” as “every car is incredibly fast.”  

Instead, the brand will need to look at how to be different because buyers will soon drive “a brutally fast [electric] sedan” every day and so will “want something different”.

Roma said: “And so that's our challenge – to come up with that something different, that something engaging. 

“When you're buying a car like a Corvette, why are you buying it? You're buying it because you want something special. You want to be engaged in the art of driving. 

“And so when we can figure out how to do that, and as we put more electrification in the car, we will, but we're not going to do an electric version of this car just to do it. That would defeat the entire purpose.

“Everybody should just take a deep breath and relax, and we'll get there when it's time.”

Roma also said GM won't accelerate development of an EV Corvette just so the car can stay on sale in Europe after 2035. “We will not make a car just to meet that regulation,” he said.

From 2035, all new cars sold in the European Union and the UK must emit zero emissions when driven, meaning that only electric cars will be allowed on sale. As such, to continue being sold here, Corvette must bring to market an EV.

“I'm not gonna make an EV and put a Corvette badge” if it is not worthy of the brand’s “70-plus years of history”, said Roma “Nobody wants that. Sorry, I will stand firm on that. The badge means something to people.”

A key reason for not rushing out an electric Corvette, Roma told Autocar, was that the Corvette is a global car, so when an electric Corvette is finally released, it needs to appeal to all markets.

Asked what needs to happen to get to that point, he said: “The things that we would need to be true – the power-to-weight ratio of the electrification components, the cost, the range. All of the things that you would need to make a car that we think would be worthy. I'm not sure you could do it, or if you could, it would be just brutally expensive.

He added: “Our cars will be all-electric when an all-electric car is better than what we have right now. And until then, we'll continue to do what we're doing right now. 

“What we need to figure out to get to that point is how do you get that visceral connection, that personality that you want to engage with, in an electric car. 

“Frankly, and I've driven a lot of really good electric cars, most of them don't have that emotional connection and the computer does so much of the work. But when I want to go on a Saturday morning and go for a drive, I want to fire up [an engine] and listen to all those noises.”
