The Porsche Mission E is a big deal for the famous Stuttgart automaker. The all electric vehicle will usher the company into a new era of car-making, and we already know that the Mission E is being heavily benchmarked against the highly successful Tesla Model S.

In its most potent P100D guise, the Model S sprints from zero to 96 km/h (0-60 mph) in 2.5 seconds and has a range of 613 km (based on the NEDC) thanks to the larger 100 kWh battery pack. However, when asked about Tesla’s acceleration, Porsche says that the Model S’ system is throttled and the third sprint attempt will “fail”.

Stefan Weckbach, Head of Battery-Electric Vehicles at Porsche, said in an interview that the Model S can achieve 2.5 seconds, “but only twice – the third attempt will fail. The system is throttled. Porsche drivers won’t need to worry about anything like that happening. The Mission E will offer reproducible performance and a top speed which can be maintained for long periods. And that’s not all. The longitudinal and lateral dynamics of the Mission E will be typical of a Porsche and represent a real treat for any driver.”

Electrek however, begs to differ. The publication said the “throttled” comment was actually incorrect, because while Tesla has limited the power output of its performance vehicles in the past, owners can still access the car’s full power through launch mode.

“Furthermore, while it’s true that acceleration is affected by the state of charge of the battery pack and temperature of the powertrain (among many other factors), it would be inaccurate to say that Tesla Model S drivers can’t launch the vehicle more than twice before they can’t achieve a 0-60 mph acceleration in less than three seconds,” added the report.

There is some merit to Weckbach’s comment, though. Tesla cars are not optimised for long periods of high-speed runs, and doing so will cause massive range drainage. Weckbach claims that the Mission E will not suffer from the same problem, but did not back those claims with details.

So far, we only know that the Mission E will get between 402 hp and 670 hp. The power comes from two motors on four-wheel drive versions – a 160 kW (215 hp/300 Nm) front motor with 441 Nm of torque on overboost, and a more powerful rear motor. Two outputs are available for the latter – 240 kW (322 hp/340 Nm) and 320 kW (429 hp/550 Nm) – and there’s also a two-speed transmission and an optional electronic limited-slip differential.

The Mission E will sprint from zero to 100 km/h in less than 3.5 seconds (which is admittedly much slower than the Model S P100D) and to 200 km/h in under 12 seconds. It will get a pure electric range of over 500 km, along with a proprietary Turbo Charging system that will provide more than 400 km of range on a 15-minute charge.
