Porsche’s upcoming Mission E sedan is expected to feature a 95 kWh battery pack and 310 miles of range. Such a generous range is sure to create demand for faster charging times, so the German luxury brand has developed a new charging system that can deliver up to 800 V and 350 kW.
Now Porsche says it plans to install 320 kW DC fast chargers at all 189 Porsche dealerships in the US. The new stations should be able to charge a Mission E to 250 miles in 20 minutes.
Meanwhile, Dr. Stefan Weckbach, Porsche’s VP for Battery Electric Vehicles, took a shot at Tesla, telling a group of journalists that the Mission E’s performance can repeatedly deliver fast acceleration, whereas Tesla vehicles can only hit 60 in 3 seconds twice in a row. “The third attempt will fail,” Weckbach said. “The system is throttled. Porsche drivers won’t need to worry about that [because the Mission E can deliver] reproducible performance and a top speed which can be maintained for long periods.”
As Autoblog pointed out, however, his claim is questionable. “At one time Tesla did restrict the number of consecutive and total Launch Control deployments, as well as “full-pedal acceleration,” in order to save wear and tear on the battery and powertrain,” writes
Jonathon Ramsey. “However, Tesla erased the software restriction late last year after voluminous customer complaints.”
