The New BMW M5 Takes BMW M GmbH Into New TerritoryAug 21th, 2017
The new BMW M5 takes BMW M GmbH into new territory, with M xDrive all-wheel drive featuring in the high-performance sedan for the first time. This change of tack sees the M5 exploring new dynamic dimensions and offering greater everyday practicality in all driving conditions. The new car is committed to building on the tradition of a concept – the luxurious four-door business sedan with a taste for the race track – first glimpsed in 1984 with the original BMW M5.
The new M xDrive developed by BMW M GmbH is the most emotionally engaging all-wheel-drive system yet to grace the high-performance segment. It works with a central transfer case with multi-plate clutch and distributes drive fully variably between the front and rear axle, as required. Another ingredient in the car’s supreme traction in all road and weather conditions is the Active M Differential at the rear axle, which also works fully variably and has a locking effect between 0 and 100 per cent. The character of M xDrive can be adjusted as desired. The driver has five different configurations to choose from based on combinations of the DSC modes (DSC on, MDM, DSC off) and M xDrive modes (4WD, 4WD Sport, 2WD). In the basic setting with DSC (Dynamic Stability Control) activated and 4WD, the system permits slight slip through the rear wheels when accelerating out of corners – and therefore plays its part in giving the new BMW M5 its sporting agility. In M Dynamic mode (MDM, 4WD Sport) M xDrive allows easily controlled drifts. The three M xDrive modes with DSC switched off have been conceived to sate the appetites of keen drivers and primarily for use on the track. Here, the driver can choose from three configurations up to and including pure rear-wheel drive (2WD). This mode allows the driver to pick their own drift angle and treats connoisseurs to driving dynamics in their purest form.
Providing ample power for the new BMW M5 is a 4.4-litre V8 bi-turbo engine with M TwinPower Turbo technology. The M engineers have carried out significant revisions to the outgoing model’s power unit. For example, newly developed turbochargers, ultra-efficient indirect charge air cooling and increased fuel injection pressure together help to raise output and, above all, torque. The engine develops 441 kW/600 hp at 5,600 – 6,700 rpm, while a monumental 750 Nm (553 lb-ft) of torque is placed at the driver’s disposal from as low down as 1,800 rpm and remains there until 5,600 rpm. A map-controlled, fully variable oil pump ensures oil is supplied as and when the new BMW M5 needs it, even on the track. The car’s impressive performance figures speak for themselves: 0 to 100 km/h (62 mph) in just 3.4 seconds, 0 to 200 km/h in 11.1 seconds (124 mph). Top speed, meanwhile, is an electronically limited 250 km/h (155 mph), but the optional M Driver’s Package can keep the fun coming to 305 km/h (189 mph).
The new BMW M5 channels all that power through a specially tuned eight-speed M Steptronic transmission with Drivelogic. In D mode it provides all the comfort and convenience of fully automatic gear changes, but can then also switch to sequential manual shifts. The driver can do this using either the compact selector lever on the centre console or the steering wheel-mounted paddles. Drivelogic allows the driver to adjust the transmission’s characteristics to their personal preferences. For track use, the eight-speed M Steptronic unit serves up lightning-fast shift times, helping to give the new BMW M5 its exceptional agility and dynamic flair. The suspension of the new BMW M5 is likewise designed to deliver both maximum traction for everyday use and supreme dynamic performance on the track. Like the engine, transmission and M xDrive system, it has been tuned by experts and racing drivers at venues including the world’s most exacting test facility – the Nürburgring Nordschleife circuit. Sophisticated stiffening elements in the front and rear structures ensure the body structure is extremely rigid and therefore that the car provides instantaneous feedback, in particular when the driver is pushing hard on the road or track.
The driver can also choose from Comfort, Sport and Sport Plus modes for the Variable Damper Control (VDC) system – which has M-specific tuning – and the M Servotronic steering. And the engine’s characteristics can also be configured to the driver’s tastes via the Efficient, Sport and Sport Plus modes. The two M1 and M2 buttons on the M leather steering wheel can be used to store two set-ups combining the driver’s preference of engine, transmission, suspension and M xDrive modes, the DSC mode and Head-Up-Display settings. The driver can then activate their preferred set-up by pressing the relevant button. The new BMW M5 includes revisions to its bodywork over the regular BMW 5 Series to satisfy its challenging dynamic brief. The M engineers have redesigned the broader front side panels and front bumper trim to include larger apertures for the air feeding the cooling systems and brakes. Also new is the rear diffuser. The exhaust system’s quartet of tailpipes are a visual pointer to the power generated by the BMW M5 and also lay on a suitably sporting soundtrack for the job in hand, courtesy of their flap control system. The driver can use a button to adjust the engine sound as desired.
The bonnet, which also has an M-specific design, is made from aluminium and boasts eye-catching sculpture lines. These extend into the extremely lightweight carbon fibre-reinforced plastic (CFRP) roof – a standard feature of the new M5. The weight savings contributed by the CFRP roof and other components such as the exhaust system help to ensure the new BMW M5 with M xDrive all-wheel drive is lighter than its predecessor. The new BMW M5 is fitted as standard with M compound brakes, which are lighter than conventional grey cast iron items and therefore also bring down the car’s weight. With blue-painted six-piston fixed callipers at the front and single-piston floating callipers at the rear, plus perforated, inner-vented brake discs all round, the M compound brakes have the speed-shedding power to befit the car’s dynamic potency. The optional M carbon ceramic brakes, which can be identified by callipers painted in a gold colour and shave another 23 kilograms off the M5’s weight, can withstand even greater punishment.
The new BMW M5 comes as standard with polished 19-inch light-alloy wheels (front: 9.5 x 19, rear: 10.5 x 19) in Orbit Grey and M-specific tyres (front: 275/40 R 19, rear: 285/40 R 19). 20-inch items can be specified as an option (front: 275/35 R 20 tyres on 9.5 x 20 rims, rear: 285/35 R 20 tyres on 10.5 x 20 rims). Standard specification for the new BMW M5 also features Merino leather and M seats with electric adjustment. The options list includes newly developed M multifunction seats, which stand out with their bucket-seat-style construction and even better lateral support.
