BMW i3

?The BMW i3 is a well-resolved all-round concept, with every detail conceived and optimised to fulfil its eventual purpose. Central to its design is the innovative LifeDrive architecture, the key to the BMW i3 Concept's appeal as a light, safe and spacious car. Innovative use of materials and intelligent lightweight design not only enable the i3 Concept to travel long distances on a single charge and provide superb safety in the event of a collision, they also help give the car its excellent driving dynamics. The secure arrangement of the battery in the Drive module gives the vehicle a very low centre of gravity and optimum weight distribution. The electric motor over the rear axle - which generates output of 125 kW/170 hp and impressive torque of 250 Nm (184 lb-ft) from a standstill - and a small turning circle combine to deliver pleasingly crisp driving characteristics and give the driver a very immediate experience of the BMW i3 Concept's lightweight design. The BMW i3 Concept accelerates from 0 to 60 km/h (37 mph) in under four seconds and from rest to 100 km/h (62 mph) in less than eight seconds. The extremely direct sensation at the wheel is expressed in outstanding agility at low speeds and during turning manoeuvres, and makes parking in tricky situations that much easier.

The electric motor developed by BMW and the optimised lightweight design of the LifeDrive architecture cannot take all the credit for imbuing the car with such efficiency and enabling it to travel such long distances on each charge. Indeed, the ability of the car to recoup energy while on the move and special range-extending functions, such as ECO PRO mode, also add miles to the clock. With ECO PRO mode activated, all the vehicle functions operate with maximum efficiency. For example, the accelerator mapping is tweaked to limit the output summoned when the driver flexes his right foot, and the climate control functions also use as little energy as possible. Added to which, sophisticated aerodynamics and slim, low rolling resistance wheels minimise resistance to the car's forward progress and maximise its range.
