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.
Another consideration with an all-electric supercar is the extra weight, which would put the tyres, brakes and steering under excessive strain at the cornering and stopping speeds that are common on the Nurburgring.
The next major technology advance coming in electrification is solid state batteries, but they are in the R&D development phase now with series production a number of years away.
“Porsche has never had a plan to bring out a super sports on a regular cycle,” said Steiner.
