The obvious next-step for a Porsche ‘super-sports’ is an all-electric powertrain, but company engineers have warned that the high weight of today’s batteries makes such a car unlikely in the near future.
“A future super-sports is a matter of technology. If we were to do it now, it would be a hybrid. But we have already done that with the 918,” said R&D boss Michael Steiner.
An all-electric supercar could produce acceleration times that would fit Porsche’s performance criteria, but the car would also have to beat the 918 Spyder’s lap time around the Nuburgring Nordschleife.
While that might be possible with an all electric car, Steiner warned that the rate at which charge would have to be drawn from a supercar’s batteries is likely to lead to cell damage, cutting the working life of the battery.
“And I don’t think our customers are ready to treat the battery as a replaceable item, yet,” said Steiner.
