The BMW ActiveHybrid 5 will receive its world premiere at the 2012 Detroit Motor Show.

The ActiveHybrid 5 combines 340 hp with CO 2 emissions of 149 g/km, and has a 2.5 mile driving range on electric power, along with an electric-only top speed of 37 mph.

It has a coasting mode, with the engine switched off, which is active at up to 100 mph, and an e-boost function delivers dynamic acceleration.

There will also be a new BMW ActiveHybrid 3, which will arrive in autumn 2012. Apart from the ActiveHybrid 3, in the US the new 3 Series will be available with two BMW TwinPower Turbo engines, the 2.0-litre 328i and the 3.0-litre 335i. Auto Start-Stop comes as standard with all engine-gearbox combinations.

The new 3 Series retains a longitudinal front-mounted engine, rear-wheel drive and 50:50 weight distribution.

As well as the new 3 Series, BMW will showcase its new i brand at the Show.

The BMW i3 Concept is driven purely by electric power. Its LifeDrive architecture means that the BMW i3 Concept can travel long distances on a single charge, has high levels of safety in the event of a collision, and has excellent driving dynamics.

The electric motor over the rear axle generates an output of 125 kW/170 hp and torque of 250 Nm (184 lb ft) from a standstill. The BMW i3 Concept accelerates from 0 to 37 mph in under four seconds and from rest to 62 mph in less than eight seconds. It has four seats, wide-opening opposing “coach” doors, a boot capacity of around 200 litres and an additional compartment in the front.

Remote functions accessible via a smartphone enable owners to find their vehicles, flag up nearby charging stations, allow battery charging and preconditioning at the touch of a button, and supply information on the current status of the vehicle.

The BMW i8 Concept is a plug-in hybrid concept combining the modified electric drive system from the BMW i3 Concept – fitted over its front axle – with a three-cylinder combustion engine producing 164 kW/220 hp and 300 Nm (221 lb ft) at the rear. Working in tandem, they allow the two drive systems to deliver the performance of a sports car but the fuel consumption of a small car.

The 2+2 seater has acceleration of 0 to 62 mph in under five seconds combined with fuel consumption of approximately 94 mpg. Its lithium-ion battery can be charged from a domestic power supply, allowing the car to travel up to around 20 miles on electric power alone.

The motor in the front axle module and combustion engine at the rear are connected by an “energy tunnel”, which houses the high-voltage battery. This gives the car a low centre of gravity – and the positioning of the electric motor and engine over their respective axles and the space-saving and well-balanced packaging of all components result in an optimum 50/50 weight distribution.
