A new all-aluminium 3.0-litre straight-six cylinder diesel engine produces 245hp at 4,000rpm and a torque figure of 540Nm attained from 1,750rpm through to 3,000rpm. The 2,993cc powerplant posts the lowest ever CO2 figure of any BMW 7 Series before it and it is also the most economical 7 Series ever (39,2mpg, 192g/km). It can accelerate from zero to 62mph in 7.2 seconds and has a 152mph top speed. The performance of the 730d is, in part, possible due to third-generation common-rail direct injection incorporating piezo injectors that operates at a peak pressure of 1,800 bar. This system ensures a near perfect combustion process. Weighing 185kgs the new six-cylinder diesel engine is also 5kgs lighter than its predecessor.
The BMW 750i and 750Li are the range flagships. The new 4,395cc V8 engine from the recently launched X6, featuring twin-turbochargers and high-precision direct injection technology, produces 407hp from 5,500rpm to 6,400rpm. Figures that are backed up by 600Nm of torque from 1,750rpm to 4,500rpm. This sees the BMW 750i accelerate from zero to 62mph in 5.2 seconds (5.3 seconds for the 750Li) before going on to an electronically-limited top speed of 155mph. Consumption on the combined cycle is 24.8mpg, while CO2 emissions equate to 266g/km.
The all-aluminium V8 engine powering the 750i and 750Li also features its own twin-turbochargers and catalysts that are placed within the V-space of the engine block. This not only optimises packaging but the reduction in manifold length and larger cross sections mean the engine breathes better for enhanced performance.
Aimed at customers who prefer the characteristics of a petrol-powered BMW six-cylinder engine, the BMW 740i and 740Li are also offered. Using a 2,979cc powerplant, the BMW 740i musters 326hp and 450Nm of torque for performance. The twin-turbocharged engine features high-precision direct injection and Double-VANOS variable valve technology to achieve optimum performance. The 3.0-litre BMW 740i and 740Li post combined fuel consumption figures of 28.5mpg and 28.3mpg respectively, while returning emissions figures of 232g/km and 235g/km. All BMW 7 Series models come with a six-speed automatic gearbox as standard.
The launch of the new 7 Series completes the line-up of the entire BMW range now being equipped with EfficientDynamics technologies fitted as standard. With its roof, doors, bonnet and side panels all made from aluminium to dovetail with the principle of lightweight engineering, the 7 Series also has other innovative technology which improves engine performance, while cutting fuel consumption and emissions.
All 7 Series can now be specified with Head-up Display incorporating a speed limit warning system. A camera mounted on the back of the rear view mirror scans oncoming road signs to alert the driver of any impending speed restriction. The BMW 7 Series is also available with a Side View camera system that operates in conjunction with Park Distance Control. The system provides an overview of traffic conditions on the iDrive display so the driver can negotiate a partially obscured junction, leave a car park or drive through a narrow gate with absolute confidence.
Completing the host of innovations is speed-related Integral Active Steering. A car specified with this optional equipment allows the rear wheels to turn by up to 3º. At slow speeds it is highly manoeuvrable, while at a faster pace it offers enhanced composure and driving dynamics. BMW's flagship car is also the first to come with full-scale Internet connectivity.
The latest generation BMW 7 Series is the first to have Dynamic Driving Control featuring Dynamic Damping Control as standard. Dynamic Driving Control is the umbrella function that lets a driver customise the characteristics of his or her car. As part of this Dynamic Damping Control can bet set in comfort, normal or sport modes, but, for the first time, with the added benefit that these settings are infinitely variable depending on driving style and road surface condition. Depending on selected mode the throttle response, gear change speed and steering feel are also altered at the same time.
To aid driving dynamics and comfort the 7 Series is the first BMW Saloon to feature race car-like double-wishbone front suspension. This arrangement allows engineers to fine-tune the suspension for the best kinematic configuration. The rear suspension consists of a five-link arrangement made of aluminium which can be further optimised with the inclusion of Adaptive Air Suspension.
