BMW 7-Series
BMW 7-Series review:
The launch of the fifth generation of the BMW 7 Series sets a new benchmark in automotive luxury, technical innovation and class-leading driving dynamics, combined with emissions reducing and fuel saving technology.
The flagship of the BMW model range debuts in November with a host of world firsts and will initially be offered with a choice of three powerplants, one diesel and two petrol engines. The two petrol-powered cars will be offered with a long-wheelbase body too. All three engines produce more power yet use less fuel and produce less emissions than the models they replace.

The BMW 730d sets a new benchmark in terms of drivetrain performance. The new all-aluminium 3.0-litre straight-six cylinder diesel engine produces 245hp at 4,000rpm. Its effortless real world driving smoothness comes courtesy of a peak torque figure of 540Nm attained from 1,750rpm through to 3,000rpm.
The 2,993cc powerplant posts the lowest ever CO2 figure of any previous BMW 7 Series and it is also the most economical 7 Series ever. Its 192g/km emission figure is class-leading for conventionally powered luxury cars, while no other competitor comes close to its 39.2mpg combined consumption figure. It can accelerate from zero to 62mph in 7.2 seconds and has a 153mph top speed.
To put the BMW 730d’s competitive advantage in context this luxurious vehicle records near identical fuel consumption and CO2 emissions to the Mercedes C320CDi – a car that is two market segments below the 7 Series and is smaller and lighter than the BMW.
The impressive performance of the 730d is, in part, possible due to third-generation common-rail direct injection technology, 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 730d is set to be the biggest seller in the UK, accounting for approximately 85 per cent of sales.
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; impressive figures that are backed up by an equally stunning 600Nm of torque from 1,750rpm to 4,500rpm. Such breathtaking performance 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 world first - 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. Double-VANOS variable valve technology and high-precision direct injection technology further aid engine performance to the degree that all the innovations combine to offer a V8 engine that has an equivalent output of a traditional 12-cylinder unit.
Aimed at customers who prefer the characteristics of a petrol-powered BMW six-cylinder engine, the BMW 740i and 740Li are also offered. Using an internationally-acclaimed 2,979cc powerplant, the BMW 740i musters 326hp and 450Nm of torque for rapid yet serene performance. The twin-turbocharged engine features high-precision direct injection and Double-VANOS variable valve technology to achieve optimum performance. The car accelerates from zero to 62mph in 5.9 seconds (6.0 seconds for the 740Li) before going on to an electronically-limited top speed of 155mph. The 3.0-litre BMW 740i and 740Li post combined fuel consumption figures of 28.5mpg and 28.2mpg 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.
