The revised BMW i3 concept reveals a more production realistic interior and exterior, ahead of the car’s mainstream production in 2013. Seen here, the i3's cabin is all-new, while the exterior remains the same as before apart from a new paint colour. The BMW i3 was unveiled alongside a 20kg electric bicycle concept, called the BMW i Pedelec.
According to Benoit Jacob head of i design, "What we see here is 85 to 90 per cent production ready. Very close, but visual details like doors can be expected to change - the i8 spider shown in Beijing didn't have see through doors so that gives clues."
The BMW i3 is constructed using two independent modules. The structural Drive module is made of aluminium and incorporates the battery, drive system and chassis. The second, so-called Life module is made of lightweight carbonfibre reinforced plastic. The car’s target weight will not exceed 1250kg.
The BMW i3 is powered by a 168bhp electric motor that sits over the rear axle the electronics systems, transmission and differential, ensuring no cabin encroachment. It produces 170 lb ft of torque from a standstill and a single-speed gearbox delivers power to the rear wheels. BMW claims the i3 will accelerate from 0-37mph in under four seconds and to 62mph in under eight seconds. The i3 has a top speed of 93mph.
Energy comes from lithium ion batteries positioned under floor to ensure the best weight balance. BMW claims that the i3 will achieve a pure electric range of 100 miles and has confirmed that the model will be made available as a range extender model too, which is where BMW sees most potential for growth of sales.
