German automaker Porsche is planning to introduce all-electric and hybrid models of its 911 series, Cayman and Boxster. But the challenge is to maintain the low ride height and class-leading handling.
Autocar reports that the German carmaker is evaluating the use of solid-state batteries instead of lithium-ion batteries.
Porsche aims to launch an electrified version of each of its model by 2030 as part of Volkswagen Group's corporate goal which was announced at the 2017 Frankfurt Motor Show.
Porsche will offer the hybrid variant of the 911 series by the end of 2017, whereas an all-electric Boxster is expected to be the first fully electrified model. The company is already testing the prototype version of the electric Boxster.
The electric version of the Boxster has performed well, but its track times were slower due to the added weight of the battery which also affected the handling of the car. Placing a battery in the 911 will be an even bigger challenge due to its aesthetics.
If the battery is placed between the wheel in the chassis, it will result in the increased ride height which will also increase the centre of gravity. A potential solution is to replace the rear seats with the battery. But it will be no longer a 2+2 sports car.
Another solution is to use a T-shaped battery which will be fitted into the centre tunnel and the rear seat. The 911, Boxster and Cayman are also expected to borrow battery technology and other components from the Mission E, an all-electric four-door EV from Porsche which will go on sale by 2020 in the global markets.
Volkswagen Group has an ambitious plan of having electrified vehicles across all the brands by 2030. Porsche is also working towards achieving the goal and planning to utilise the solid-state batteries due to its compact size.
