This is an odd-shape BMW 1 Series with new-age propulsion; dash has been modified to show battery charge and energy status.
The all-electric BMW ActiveE serves as a real-world test-bed for BMW’s upcoming eco sub-brand, “i”. The German automaker has registered the first batches of ActiveE test cars for trials in Europe, the US and China, with the international test fleet eventually numbering a thousand units. We got to drive one of the first in BMW’s hometown.
The “range anxiety” of potential buyers is still a major roadblock for the mass market commercialisation of electric vehicles (EVs). Having driven the ActiveE under normal traffic conditions around Munich, I can attest to a realistic range of about 140km in maximum-efficiency Eco Pro mode – more than enough for the typical daily commute in an urban environment.
Incidentally, the figure I achieved is not far off the claimed 160km range. The catch is, Eco Pro limits the car’s electric power output.
With the motor’s full 125kw (equivalent to 170bhp) and 250Nm made available, the 1.8-tonne ActiveE accelerates to 100km/h in a respectable 9 seconds. More importantly, it handles like a compact BMW should. The ride quality and steering are spot-on, despite the 480kg weight penalty over a conventional 120i.
Credit goes to the perfect 50:50 weight distribution. This was made possible by the neat replacement of the engine block, transmission and fuel tank by the three large lithium-ion battery modules, which are protected by a steel plate housing with an integrated liquid cooling system.
On the move, there is a very high amount of regenerative braking when you lift your foot off the “throttle” pedal. What this means in practical terms is that about 75 percent of so-called situational deceleration can be achieved without ever pressing the brake pedal – translating into about 20 percent more range.
When its juice runs out, the ActiveE can be recharged overnight from a conventional socket at home or the office, or in around five hours using a wall-mounted 32-amp quick-charger.
The ActiveE feels complete and well-made for what is ostensibly a research vehicle. It will be leased out to select “customers” under a special 24-month programme to collect data and feedback on BMW-style electric motoring.
