Superior in every regard. The new BMW M5.

Maximum torque increased by 30 per cent up on predecessor model, engine output 10 per cent and fuel consumption cut by more than 30 per cent. The most powerful BM W M car ever. Let’s have a look into the details of the fifth generation of the world’s most successful high-performance saloon in the premium segment of the executive class. The new BMW M5 is an exceptionally dynamic high-performance sports car with four doors and five seats. It combines compelling track potential with the comprehensive practicality of a luxurious business saloon including supreme long-distance comfort.

High-revving V8 engine with M TwinPower Turbo technology sets new standards in output and efficiency.

For the first time, a BMW M5 has a turbocharged engine to thank for its outstanding dynamics. The 4.4-litre engine develops top output of 412 kW/560 hp at 6,000 – 7,000 rpm, while its maximum torque of 680 Newton metres (502 lb-ft) is on tap between 1,500 and 5,750 rpm. The rev limiter intervenes at 7,200 rpm. The rev band, which offers extremely dynamic acceleration between the arrival of peak torque and the availability of maximum output, is therefore almost three times as wide as that of the predecessor unit.

The engine’s intoxicating thrust gives the new BMW M5 impressive acceleration. The sprint from rest to the 100 km/h (62 mph) mark is all over in 4.4 seconds, and from that point progress continues with barely any let-up. Indeed, the M5 needs just 13.0 seconds to race from 0 – 200 km/h (124 mph). Maximum speed is electronically restricted to 250 km/h (155 mph); if the optional Driver’s Package is specified, this limit is raised to 305 km/h (190 mph).

Nobody likes pit stops. An increased fuel tank of 80 litres and improved efficiency with an average fuel consumption in EU test cycle of 9.9 litres/100km (28.5 mpg imp) significantly raise the cruising range. The improved balance between the performance-focused M experience and the car’s fuel consumption stems from the exceptionally impressive efficiency of the new V8 engine and from far-reaching Efficient Dynamics technology including the Auto Start-Stop function and Brake Energy Regeneration.

Does the new V8 engine show the excellent throttle response BMW M cars are famous for? Yes. There is a set of reasons for this:

The two turbochargers of the eight-cylinder engine are accommodated, along with the catalytic converters, in the V-shaped space between the cylinder banks, which are positioned at a 90-degree angle to one another. This arrangement produces an extremely compact construction and allows model-specific positioning of the intake and exhaust ducts. Their reduced pipe length and larger cross section minimise the pressure losses on the exhaust side of the engine.

BMW’s patented and globally unique cross-bank exhaust manifold ensures additional optimisation of the gas flow on the way to the two twin-scroll turbochargers. It is made up of four separate exhaust ducts, which are connected with the exhaust ports of two combustion chambers – one on the left-hand cylinder bank and one on the right. Identical pipe lengths and a combustion chamber arrangement mirroring the firing sequence ensure the gas flows through the exhaust ducts at an even rhythm. In each case, two of the four exhaust gas ducts supply one of the two turbos, having been channelled together shortly before they reach the turbine. The result is a consistent level of pressure acting on the two turbochargers, without any kind of counter-flow. This ensures the turbines respond extremely rapidly and charge pressure remains constant.

This ensures the turbines respond extremely rapidly and charge pressure remains constant.

The turbochargers developed specially for the engine powering the new BMW M5 stand out with their particularly high level of compressor and turbine efficiency, and deliver maximum charge pressure of 1.5 bar. Their innovative construction principle uses the potential of turbocharging to deliver an efficient output boost of unprecedented potency. The latest version of M TwinPower Turbo technology provides a level of responsiveness, intensity and smoothness in its power delivery unmatched in the segment.

High Precision Injection petrol direct injection ensures an extremely precise supply of fuel to the combustion chambers. Injectors positioned centrally between the valves within immediate range of the spark plugs spray the fuel into the combustion chambers with maximum pressure of 200 bar, providing smooth and clean combustion.

Innovative solenoid valve injectors in the new BMW M5 engine use multiple injections to achieve an extremely precise mixture preparation. Plus, the cooling effect of the direct injections enables an extraordinarily high compression ratio for a turbocharged engine, which further increases the efficiency of the V8 engine.

The M TwinPower technology of the new eight-cylinder engine also includes VALVETRONIC fully variable valve control. This system controls the amount of lift of the intake valves. Throttle losses in the gas cycle are therefore minimised, which has a positive impact on both the efficiency of the powerplant and its torque development. The integration of VALVETRONIC therefore sharpens both the responses and efficiency of the V8 engine in the new BMW M5.

Double-Vanos fully variable camshaft control plays its part both in optimising the engine’s efficiency and generating high torque at low engine revs

High performance applies to power transfer as well: the seven-speed M Double Clutch Transmission with Drivelogic.

The new BMW M5 is kitted out with a seven-speed double-clutch transmission to ensure that the transfer of engine output to the rear wheels serves up the time-honoured M experience. The M DCT Drivelogic system developed specially for the M5 has been tuned precisely to the performance characteristics of the V8 engine

The system’s control concept follows similar lines to the sequential M transmission in the predecessor car. Both in automated mode (D) and manual (S) it delivers exceptionally fast and clean gear changes. M DCT Drivelogic offers three shift programs in both automated and manual mode. The driver selects his desired mode using the rocker switch positioned immediately behind the shift lever on the centre console. More sporty or laid-back driving styles may be promoted.

BMW M cars are equipped with a specially developed differential for the rear axle to allow the driver to enjoy the benefits of rear-wheel drive to the full – in the form of the sharpest possible driving dynamics. A variable locking function splits engine power between the right and left rear wheel to generate maximum traction. Another innovation in this area that is fitted in the new BMW M5 ensures even more precise distribution of drive according to the situation at hand; the Active M Differential optimises stability with the help of an electronically controlled multi-plate limited-slip differential, which intervenes at an early stage to prevent wheel spin.

http://www.bmw.com/_common/shared/ne...ntial_lock.jpg

The rear axle’s multi-plate limited-slip differential works with extremely high precision and speed. Its control unit is connected with the DSC (Dynamic Stability Control) system via FlexRay high-speed data transfer technology and constantly cross-checks the data collected by its sensors with the feedback from DSC. It then uses this information to calculate the locking force required to deliver optimum traction and stability. The data recorded by DSC sensors is also passed on if the stability control system is switched off. The locking force within the differential can be set between 0 and 100 per cent. The Anti-lock Braking System retains full functionality in all situations.

In addition to its own data and that provided by DSC, the Active M Differential’s control unit also takes into account the position of the accelerator pedal, the rotational speed of the wheels and the car’s yaw rate. Every driving situation is therefore precisely analysed and an impending loss of traction on one side of the car identified at an early stage. The degree of lock is adjusted as required within a fraction of a second, enabling wheel spin to be prevented on slippery surfaces, in instances where the right and left rear wheel have widely differing friction coefficients, in tight bends and when changing direction extremely dynamically. Optimising traction in this way also provides unbeatable driving stability in challenging conditions and allows impressively dynamic acceleration out of corners. Plus, the Active M Differential also counteracts – to great effect – a loss of traction during double lane changes at high speed and a tendency to understeer under sudden load alterations during dynamic cornering.

M-specific chassis shows racing know-how and unparalleled development expertise.

http://www.bmw.com/_common/shared/ne...fahrwerk_2.jpg

The new BMW M5 comes with bespoke chassis technology whose construction and set-up are defined by extensive expertise from the race track. Specially developed axle kinematics and newly developed components boasting impressive strength and minimised weight meet both the requirements of everyday road driving and the specialised demands of track use. Chassis mountings using large panels at the front and rear axle ensures dynamic forces are passed evenly through to the body. The chassis transfers the potential wrapped up in the engine’s remarkable output onto the asphalt with assurance and a finely-honed sense of dynamic drama. All of which allows the BMW M5 to set new benchmarks in its segment not only in terms of sprinting power and elasticity, but also lateral acceleration, handling properties and braking performance. As with every BMW M car, the engineers carried out the fine-tuning that underpins the perfect M experience during extensive testing on the Nürburgring’s Nordschleife circuit.

The new BMW M5 is equipped as standard with electronically controlled dampers. Dynamic Damper Control uses electrohydraulic damping force adjustment to provide a set-up suited to the driving situation or the wishes of the driver. The damper settings can be adjusted at the touch of a button. In “Comfort” mode the dampers respond adaptively to the condition of the road surface and the driver’s style. “Sport” mode activates a noticeably stiffer damper set-up, while “Sport Plus” allows further stiffening of the suspension to achieve maximum longitudinal and lateral acceleration in ultra-dynamic driving situations.

M Dynamic Mode (MDM) can be activated to override the basic setting by pressing the DSC button on the centre console. This mode generates the familiar M self-steering response by raising the intervention thresholds of DSC. “DSC Off” mode can also be activated at the touch of a button.

High-performance compound brakes

The high-performance braking system of the new BMW M5 guarantees outstanding stopping power. The further development of the remarkable compound construction has resulted in further optimised braking performance – resisting fade even under heavy loads – and an enviable degree of feel. The six-piston fixed-calliper brakes are radially bolted to the pivot bearing.

The M-specific light-alloy wheels for the new BMW M5 come in 19-inch format as standard and are fitted with 265/40 R19 tyres at the front and 295/40 R19 items at the rear. 20-inch forged M light-alloy wheels can be ordered as an option.

Safe and lightweight.

Hallmark M handling and occupant protection both benefit from the extraordinary strength of the BMW M5 body structure. Incredibly durable load-bearing structures and large, precisely defined deformation zones keep the forces released in a collision away from the extremely stiff passenger compartment.

An intelligent mix of materials containing a high proportion of high-tensile and ultra-high-tensile steels, as well as aluminium, help to minimise the car’s weight. Like the bonnet and front side sections, the doors of the new BMW M5 are also made from aluminium. With a power-to-weight ratio of 3.3 kg (approx. 7lb)/hp, the high-performance Saloon represents a substantial step forwards from its predecessor in this area as well.

The safety equipment fitted as standard in the new BMW M5 includes front and side airbags, side curtain head airbags for both rows of seats, three-point inertia reel seat belts on all seats, front belt force limiters and belt tensioners, and ISOFIX child seat attachments in the rear.

Two M Drive buttons now included to activate the individually configured set-up options.

On the left-hand steering wheel spoke the driver will now find two M Drive buttons, which he can use to call up a pre-configured set-up for the car. For example, the driver can save a sporty configuration using the “M1” button and a comfort-biased set-up via the “M2” button. The M Drive system in the new BMW M5 allows the driver to adjust no fewer than six parameters: the engine management, the responses of the Servotronic steering system, the M DCT Drivelogic shift program, the DSC mode, the responses of Dynamic Damper Control and the information in the Head-Up Display.

Hallmark M design elements make a genuine contribution to meeting technical requirements.

The long wheelbase, set-back passenger compartment and High-gloss Black side window borders clearly accentuate the stretched silhouette of the new BMW M5. Muscular flared wheel arches spotlight the wide track, which helps gives the car its unshakable roadholding and impressive lateral acceleration.

Dynamically formed intakes ensure precise airflow and optimum cooling. A diffuser integrated into the lower edge of the rear apron provides efficient airflow through the back end of the underfloor section.

Interior and controls: sports car cockpit with premium ambience.

The interior of the new BMW M5 brings together an inimitable combination of the driver-oriented cockpit design of a sports car, the spaciousness of a prestige saloon and the luxurious feel of a premium model. Bespoke M sports seats, fine-grain Merino leather upholstery with extended features, door sills with “M5” lettering, an M driver’s footrest, exclusive Aluminium Trace interior trim strips and the BMW Individual roof liner in Anthracite are all standard equipment, as is the iDrive control system with an up to 10.2-inch Control Display. This screen is centrally positioned and, like the controls in the central section of the instrument panel, tilted slightly towards the driver.

As well as the Head-Up Display, numerous other driver assistance systems and mobility services available from BMW ConnectedDrive are also unique in the segment occupied by the new BMW M5. The selection of optionally available systems includes Park Distance Control, a rear view camera, High-Beam Assistant, Speed Limit Info, the Lane Change Warning System, the Lane Departure Warning System, Surround View and BMW Night Vision with pedestrian recognition. Plus, innovative technologies optimise the integration of the Apple iPhone and other smartphones.
