High-performance hybrid technology from the Porsche 918 Spyder will trickle down to the mainstream sports car range, according to Porsche’s R&D boss Wolfgang Hatz. We already have a hybrid version of the Panamera and Cayenne, but a hybrid Porsche 911 is next, but not until 2018 at least, when the next-generation 911 is predicted to arrive.
“The flywheel in our 911 GT3 R Hybrid race car is very much a race car solution – we need something different for a road car,” Hatz explained. “In my opinion if you do a hybrid for the road it has to be able to drive on pure electric power.”
How far it should be able to travel before the petrol engine kicks in is a crucial factor. “The biggest enemy of hybrids is weight, so 20km to 25km for a sports car is enough. There is no need for 50km, it will add too much weight,” said Hatz.
“There are packaging issues too of course. We want to keep the proportions of the 911 and the 2+2 layout, which is a challenge,” he added. “It was the same with the 918 Spyder – presenting a concept and showing our intention is one thing, but keeping that shape for production is very difficult.”
