The new BMW 6 Series Coupé and Convertible goes on sale on 27th October 2007 and marks the latest in a long line of BMW products revealed in 2007 featuring BMW EfficientDynamics technologies. The new BMW 6 Series range features a host of innovations designed to increase performance, improve fuel consumption and reduce emissions.
The BMW 635d is the world’s first diesel-powered luxury 2+2 Grand Tourer and the launch opens up yet another new market segment by BMW. By mating BMW’s acclaimed twin-turbocharged diesel to the marque’s flagship 2-door Coupé and Convertible models, owners will now savour high-performance and economical motoring. Improved six- and eight-cylinder petrol powered models also join the range alongside the familiar V10-engine M6, while all variants receive a subtle restyling to mark the technological changes.
And to highlight how modern cars have developed, reducing emissions and improving fuel consumption, BMW will showcase two generations of the 6 Series at the SMMT’s Evolution of the Car driving event on 9 October. At the event, the first generation 1986 286hp M635CSi will line up alongside the new BMW 635d, itself delivering 286hp but this time from its class-leading diesel engine.
The new BMW 635d is powered by a twin-turbocharged 2,993cc engine with an all aluminium crankcase and third generation common rail fuel injection system, delivering 286hp and 580Nm of torque. This propels the car from zero to 62mph in 6.3 seconds while the Convertible takes 6.6 seconds. Both have top speeds electronically-limited to 155mph. However, thanks to the EfficientDynamics technologies, the Coupé still achieves 40.9mpg on the combined cycle and a CO2 emissions figure of 183g/km, while the Convertible retains near identical figures recording 39.2mpg and 190g/km.
The BMW 635d is joined in the range by the 630i and 650i, offered in both Coupé and Convertible bodystyles. The six-cylinder magnesium and aluminium engine in the 272hp 630i now features new lean burn technology in the guise of high precision direct injection and double-VANOS variable valve technology. These EfficientDynamics measures enable the 630i Coupé to record a 4.4mpg improvement up to 35.8mpg in combined fuel consumption compared to the previous model. CO2 emissions also drop by 15 per cent from 216g/km to 188g/km. The 630i Convertible attains a combined fuel consumption figure of 34.0mpg compared to 29.4mpg, while CO2 emissions drops from 229g/km to 198g/km.
