“Formula E must be the fastest-accelerating [circuit] racing car in the world,” said the 2016-17 champion.
“It has to accelerate zero to 200 quicker than F1, quicker than rallycross, quicker than all these cars. Because electrical power trains are made for acceleration – like Teslas, like all these super-fast electric cars.”
Formula E introduced its second-generation chassis this season but Di Grassi said his vision will require “massive” changes in design.
“You have to go to four-wheel-drive, you have to go to a different weight distribution, you have to do a lot of different stuff. You have to improve the tyres too to increase the grip.
“You can maybe put move-able aerodynamics. You can go as wild as you think.”
Di Grassi wants Formula E designers to use the unique aspects of electric racing to find unconventional new ways of generating performance.“What I don’t see at the moment is people being very brave to try to adopt Formula E as pure electric,” he said. “They still follow traditional motorsport ways of thinking, of designing, of sporting rules, of technical rules.
“I think Formula E has to be thought [of] separately. Motorsport is going through a transition, let’s use this transition to our advantage instead of copying something which has failed. That’s how I would see it.”
Di Grassi suggested the amount of power produced by the cars and even the number of driven wheels permitted could vary at each circuit in order to suit Formula E’s tighter tracks. The latest Formula E cars produce up to 250 kilowatts (approximately 335 bhp), a figure which he believes needs to increase significantly.
“I would go at least with the same motor we have now but twice,” said Di Grassi. “700 horsepower electric with the with the same weight, 900 kilos. Then it’s starting to get to where I would like to.”
