Do you remember the Porsche Boxster E,
the electric prototype which was supposed to help gather information as
far as the practicality of an electric roaster and the electric
infrastructure in mid 2011? Well Porsche’s plans are well on track, as
the German automaker has recently revealed the performance figures and
specs of the Boxster E after offering a demonstration with the car at the
Michelin Challenge Bibendum in Berlin.
Out of the three
prototypes Boxster E developed by Porsche, one is AWD and two are RWD.
The AWD version uses two electric motors spinning the front and rear
axles and producing a total of 241 HP (180 kW) and 540 Nm (398 lb-ft) of
torque at 12,000 rpm. These motors enable the AWD Boxster E to sprint
from 0 to 62 mph (0 to 100 Km/h)  in 5.5 seconds and also reach a
limited speed of 124 mph (200 km/h).
The FWD versions Porsche
Boxster E are only powered by a single electric motor positioned on the
rear axle, and in this case the power level reaches 121 HP (90 kW) and
270 Nm (199 lb-ft) of torque. Performance figures for the FWD Porsche
Boxster E are still notable as accelerating from 0 to 62 mph (0 to 100
Km/h) takes 9.8 seconds, while the maximum speed that can be reached is
93 mph (150 km/h).    
The electric engines powering the Porsche Boxster E are backed by a 29 kWh
lithium-iron-phosphate battery pack located where the combustion engine
used to be, which weights 341 kg (752 lbs) and takes up to 9 hours to
recharge. The Boxster E tips the scale at 1,600 Kg (3572 lbs) and
features an Active Sound Design system which replaces the engine noise
in order to make pedestrians aware of its presence on the road.
