The 730d engine has been revised and has an all-aluminium cylinder block that reduces the weight of the engine by 25kg.
As a result of this weight reduction and BMW’s new third-generation common rail diesel technology, power is increased by 12% to 228bhp at 4,000rpm.
The 730i now features the new lightweight 3.0-litre magnesium aluminium composite engine recently unveiled in the 630i and 330i. The new engine delivers 258bhp at 6,600rpm.
The new BMW 740i replaces the previous 735i with a 4,000cc V8 engine developing 302bhp at 6,300rpm.
The 745i now becomes the BMW 750i, featuring an all-new 4,799cc engine. Delivering 362bhp at 6,300rpm, it reaches zero to 62mph in 5.9 seconds.
The 760i is equipped with a 5,972cc V12 engine delivering 445bhp at 6,000rpm. This engine model achieves a zero to 62mph time of 5.5 seconds.
Standard specification of all 7-series models has increased. All cars now feature xenon headlamps, headlamp cleaning system, Brake Force Display, BMW’s two-stage brake light system, now standard across the BMW range, that alerts drivers travelling behind that the 7-series is undertaking an emergency stop.
Also, all cars specified with the navigation system and a car telephone come as standard with BMW Assist, the emergency service that uses the navigation system to pin-point the car (SE models feature navigation as standard).
