The BMW Group's plans for an electrified future will arrive
in several stages over the next
seven years, and part of the strategy will include a whopping
120-kilowatt-hour battery pack capable of providing over 400 miles of
range.
The battery specifications were noted in an Automotive
News (subscription required) report on Wednesday. BMW Group
research and development head Klaus Fröhlich told the publication that the
automaker will employ three different batteries for its future electric cars.
He also revealed the cars will have up to three electric motors.
At the low end will be a 60-kilowatt-hour battery that
should provide 280 miles of range. In the middle will be a 90-kwh battery good
for around 342 miles of range, and at the top will be a 120-kwh battery with
around 435 miles of range. Fröhlich didn't provide specifics on the
electric motors, but he explained how the system could work in an
all-wheel-drive model. For example, he said a large electric motor may reside at
the rear, while a smaller one only kicks in when the front tires require power.
The final stage of BMW's electrification plans will begin in
2021 with the iNext electric car. An i4
model will enter production shortly after and be one of 12 electric
cars the automaker plans to put into production by 2025. That same year, BMW
wants electrified vehicles to account for 15 to 25 percent of global
sales.
Future electric BMWs will ride on one of two core
platforms: front-wheel drive (FAAR) and rear-wheel
drive (CLAR). Froehlich also pledged that batteries would not
compromise design, and BMW is taking initiatives to tailor battery cell
sizes to specific vehicles.
Shown above is BMW's i Vision Dynamics concept, which was
unveiled at the 2017 Frankfurt auto show and thought to preview the design of
the i4.
