The Porsche Mission E will be smaller than the
Panamera, but the company aims to offer the same amount of room in the cabin
with a car from the class above; using an electric powertrain frees up a lot of
space but Porsche goes even further, creating a recess in the floorpan where
the rear passengers’ legs go that splits the battery tray.
The other goal with the Mission E is to feel like a
proper Porsche down the road; the company is hard at work in making the
electric four-door model a true performance car, giving it a sharp steering and
lots of grip but they also work on making the batteries and motors resistant to
heat. Using a complex cooling circuit is their way of ensuring that performance
will be constant and repeatable, unlike other electric models currently on the
market.
Porsche is considering to offer the Mission E in
three different power versions: an entry-level 402 hp, a mid-range 536 hp and a range-topping 670 hp model, with all of them being
all-wheel drive. Porsche might even add a cheaper rear-drive version later on.
The front electric motor produces 215 hp and 221 lb-ft
of torque constantly, offering up to 325l b-ft for brief sessions of wide-open
throttle. As for the rear electric motor, there will be two different versions
of it: the base one with 322 hp and 251 lb-ft of torque and the performance one
with 429 hp and 406 lb-ft of torque. A two-speed transmission is being developed
to offer full-throttle upshifts, as well as an electronically controlled rear
differential.
0-60 mph is expected to be in the mid-3 second range
while top speed will be limited to 155 mph. Porsche targets a real-world driving
range of 300 miles but most importantly, it wants the Mission E to recharge its
battery to at least 80 percent capacity in 20 minutes or less. In order to do
so, the battery cells will be able to charge with either a 800-volt capacity or
a 400-volt capacity.
Pricing for the Porsche Mission E will be set
between the Cayenne and the Panamera, meaning around the US$ 75,000 to US$ 80,000
mark, positioning it directly against the Tesla Model S when it finally arrives
in the market in 2019.
