BMW has been
developing full electric vehicles and hybrids for a while. In August,
BMW unveiled its EfficientDynamics
Diesel Plug-in hybrid concept. The car was very sporty looking
and offered impressive performance with a 0-62 mph run of 4.8
seconds. The electric engine and diesel engines combined produced 356
hp and 590 lb-ft of torque.
BMW also unveiled its Mini
E all-electric vehicle and several of the cars came to America
for testing in California. The Mini E has a 204 hp electric motor and
promises an all-electric range of 150 miles.
BMW is now set for the next phase in
its electric vehicle program and has unveiled the Concept
ActiveE. The car is a modified BMW 1 series sedan that swaps the
gasoline motor for an all-electric powertrain.
will be premiered for the first time at the North American
International Auto Show 2010 in Detroit. The new EVs will be fleet
trialed much as the Mini E was with real drivers and governments
getting hands on the vehicles for testing. The concepts behind the
ActiveE will be used to developed n all-electric production car that
BMW will sell under a sub brand in the next five years.
for the vehicle comes from advanced lithium-ion batteries that were
jointly developed by BMW and SB LiMotive. The batteries will give a
range of about 100 miles in everyday use. The new liquid-cooled
battery packs charge quickly as well. On a 50 amp, 230/240 volt
connection, the car will charge fully in three hours. On the circuits
used in America, the car will recharge in about 4.5 hours.
vehicle will be able to hit 60 mph in about 8.5 seconds. The maximum
power output is 170 hp with 184 lb-ft of torque. BMW also uses a
system to convert the vehicle's kinetic energy into power and the
system is able to increase the vehicles range by 20%. The car will
also interface with an app for smartphones allowing the driver to
check the battery level and start the climate control system to cool
or heat the car while it is on AC power.
The vehicle complete
with its battery packs weighs 3,900 lbs compared to 3,252 lbs and
3,373 lbs for a conventional BMW 128i and 130i respectively. BMW also
points out that the battery pack doesn't interfere with the 50/50
weight distribution of the vehicle and that the trunk is larger than
that of the standard 1-Series convertible at 7 cu. ft.
