BMW hybrid car to enter production

LEIPZIG: BMW will be making a hybrid sports car based on the four-seat BMW Vision EfficientDynamics concept study.

Since its introduction at the Frankfurt Motor Show in 2009, it has won several awards for its futuristic design and its engine technology.

Just 1.24 metres high, the 2+2-seater takes up the characteristic BMW shaping style. Wing doors facilitate entry to both rows of seats, while extensive aerodynamic measures reduce the drag coefficient to 0.22.

The combination of a 3-cylinder turbo diesel with a hybrid synchronous motor at the front axle and a full-hybrid engine at the rear axle enables an overall system output of 328 bhp.

The design of the BMW ActiveHybrid technology allows performance figures at the level of a sports car, with 4.8 seconds required for the sprint from zero to 100kph - with an average fuel consumption in the EU test cycle (KV01) of 3.76 litres/100km, and a CO2 emission rating of 99 grams per kilometre. and 33g CO2/km.

All engine components were designed for maximum efficiency. The intelligent linking of the power output of the three engines, as well as precisely controlled energy management including brake energy regeneration contributes to the efficiency.

The concept car was conceived as a plug-in hybrid. The lithium-polymer rechargeable battery housed centrally in a longitudinal chassis element and designed specially for this hybrid sports car can be fully charged at a conventional power socket within just two and half hours.

The use of electrical energy alone permits zero-emissions motoring with a range of some 50km, while a 24-litre diesel tank extends the total action radius of the vehicle to up to 700km.

All current models are fitted as standard with extensive measures for the reduction of fuel consumption and CO2 emissions.
