Latest Porsche EV intel

0 comments


Porsche is investigating ways of differentiating the power delivery of electric powertrains in an effort to produce a more Porsche-like driving experience, and to distinguish the performance characteristics of its future electric models from those of its competitors, says Dr. Michael Steiner, who led the development of the just-introduced Panamera Hybrid.

Electric motors produce their peak torque from the moment they start turning, a useful quality but one that threatens to homogenize the acceleration experience, especially as they produce similar sounds.

Steiner says Porsche is looking to combine PDK dual-clutch transmissions with electric motors, the aim being to encourage the driver to rev the motor more, even though this may be slightly less efficient. Changing the windings on motor armatures and using DC current rather than AC also allow the motor's characteristics to be altered.

Steiner says that extended-range electric vehicles, which use an internal-combustion engine as an on-board generator, will not feature in Porsche's plans "because we want the driving pleasure that comes from a responsive engine."

"Extended range EVs are not suitable for Porsche," he says, as demonstrated by the company's just-announced experimental Boxster E, which is pure electric.



Höchsmann Günther, Senior Engineer of Porsche and one of the fathers of the Bosxter E is seen here driving the new EV. It's not easy to understand the behavior of a car like this from the clip, however the silence presents proof of 100% electric.

The Boxster E delivers 90 kW, which should be equivalent to about 120 hp, while torque is 270 Nm settles on This translates into performance claims for the 0 to 100 km / h in 9.8 seconds against the 6.5 Boxster traditional.

At this point we say that for those not satisfied, there is the possibility of the car having two engines. If this is the case you would get 240 hp, with torque of 540 Nm and a value for the test from 0 to 100 km / h in 5.5 seconds.
