Volkswagen Group brands to offer electrified version of every model by 2030
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.
The previous cadence was the Carrera GT in 2004, prompted by the availability of carbon-fibre tub technology, followed nine years later in 2013 by the 918 Spyder, which exploited advances in hybrid technology linked to Porsche’s return to front-line endurance racing.
“The next one might be even longer,” said Steiner. That suggests a date no earlier than 2021.
Having pulled out from the WEC at the end of this year, many of the WEC team’s engineers will be redeployed to build Porsche’s Formula E car for next season.
