BMW M5 UK Version
The heart of any BMW M car is its engine, and never more so than with the new M5. For the first time an M5 features a turbocharged power unit – a high-revving 4.4-litre (4,395cc) V8, here making its world premiere. Developing 560hp from 5,750-7,000rpm, it is the most potent series-production engine ever to emerge from BMW’s high-performance M division. Incorporating the company’s M TwinPower Turbo technology, twin-scroll turbochargers, high-precision direct fuel injection, VALVETRONIC variable valve control and a cross-bank exhaust manifold, it guarantees the legendary BMW M- car thrust with seamless lag-free delivery from little more than tickover speed thanks to 680Nm of torque from only 1,500rpm.
Compared with the previous V10-engined M5, maximum power is up by around 10 per cent and peak torque by more than 30 per cent. As a result, the latest M5 can accelerate from 0-62mph in just 4.4 seconds, and 0-124mph in only 13 seconds. The voluntarily limited top speed is 155mph.
The two banks of the V8 engine are arranged at 90 degrees, leaving space to accommodate the two turbochargers and catalytic converters in their midst. This ensures that the engine is not only extremely compact, but that the catalytic converters reach operating temperature more quickly to boost efficiency, while the short length of the unique intake and exhaust ducts minimizes pressure losses. BMW’s patented cross-bank exhaust manifold optimizes gas flow to the twin-scroll turbochargers, which have been specially developed for the M5 Saloon to deliver a maximum charge pressure of 1.5 bar. The construction principle of the M TwinPower Turbo technology also helps give the M5 Saloon its distinctive V8 soundtrack.
In any BMW, performance goes hand-in-hand with efficiency, and the new M5 Saloon is no exception. With BMW’s seven-speed M Double Clutch Transmission Drivelogic and Efficient Dynamics technology, including engine Auto Start-Stop and Brake Energy Regeneration, the M5’s fuel consumption has been reduced by more than 30 per cent to 28.5mpg, while CO2 emissions tumble to 232g/km.
The transmission offers manual (S) and fully automated (D) shift options, with three programs in each, allowing the driver to select the most sporty, relaxed or efficient driving style at will via a rocker switch. There is also a low speed assistance function to keep the car moving smoothly through heavy traffic with only a light touch on the accelerator. At the same time the engine characteristics can be switched from Efficient to Sport or Sport Plus through another button in the centre console.
The M5 Saloon has bespoke M-specific suspension with specially developed axle kinematics honed not only on the race track but also through extensive testing at the Nürburgring. As a result, the chassis components are both light and strong. The new M5 comes as standard with electronically controlled dampers that allow drivers to select from three settings – Comfort for normal road use, Sport when a more dynamic driving style is preferred and Sport Plus for the most extreme driving, such as on a race track.
The driver can also choose between three settings for the M-tuned Servotronic power assisted steering. Comfort requires only a small amount of steering effort when maneuvering or parking, but still allows the instant changes of direction expected of an M car at higher speeds. Sport delivers more intensive feedback, while Sport Plus requires greater force on the wheel so that the driver gets precisely the response that is intended from every steering input.
The new M5 has six-piston caliper brakes featuring a further development of BMW’s remarkable compound construction so that they resist fade even under repeated heavy loads and deliver an exceptional degree of feel. They are mounted within 19-inch M light alloy wheels with 265/40 R19 tires at the front and 295/35 R19 tires at the rear. Forged 20-inch alloys can be specified as an option.
The dynamic appearance and authoritative stance of the regular 5 Series saloon has been lifted by M-specific design features at the front, rear and sides. These have been almost entirely dictated by the technical demands of an ultra-high-performance car.
The wide-spread M black slats in the grille and the three air intakes in the low front apron are there to satisfy the cooling requirements of the twin-turbo V8 engine, for example, while the air channeling flaps at the lower edge of the front end were developed on the race track and are designed to optimize the aerodynamics of the car.
The contours of the bonnet converge into a V shape to meet the customary BMW double-kidney grille, which sits above a forward projecting central aperture between two curving side intakes that collectively emphasize the width of the new M5 Saloon. Standard bi-xenon front light clusters contain visually unique LED light rings and indicator lights that consist of 10 LED units. LED accent lights cut across the top of the familiar BMW twin round headlamps.
A long wheelbase, set-back passenger compartment and high-gloss black side window surround accentuate the stretched profile of the new M5 Saloon. Flared wheel arches, flush 19- or 20-inch wheels and lowered M suspension ensure the car’s sporting characteristics do not go unmistaken. The wheels give a clear view of the six-piston fixed calipers of the high-performance braking system.
At the rear, horizontal lines give the M5 a wide, sporty stance, and a diffuser is incorporated in the lower edge of the apron to allow sufficient airflow through the underfloor section. A signature feature of the new M5 is the twin-tailpipe exhaust system, positioned wide on either side of the diffuser.
The instrument cluster with black-panel technology includes classic BMW M circular dials with red needles and white illumination. The multifunction buttons on the M leather steering wheel operate the cruise control, radio and telephone. On the left-hand side the driver will now find two M Drive buttons which can call up a pre-configured setting for the car – for example, a sports or a more comfort-orientated set of driving characteristics.
The driver can adjust no fewer than six parameters: engine management, the Servotronic power steering, the M DCT Drivelogic gearshift program, DSC mode, the electronically variable Dynamic Damper Control and the information relayed in the standard driver Head-up Display. These can be re-configured at any time via the iDrive menu.
The new BMW M5 offers an extensive range of standard and optional innovative driver assistance systems and mobility services in a sports car-like cockpit that meets every requirement of a premium high-performance saloon.
