#BMW The new 2018 M5 F90 with M xDrive

The new BMW M5 takes driving dynamics into a new dimension. Making its debut in the sixth generation of the highperformance sedan is the new M-specific all-wheel-drive system M xDrive. Not only does this drive system enable the M5 to reach new heights of dynamic performance, it means that it excels in terms of everyday practicality and delivers supreme poise in all driving conditions as well.
Frank van Meel, Chairman of the Board of Management at BMW M GmbH, explains the benefits of the pioneering drivetrain technology aboard the new BMW M5: "Thanks to M xDrive, the new BMW M5 can be piloted with the familiar blend of sportiness and unerring accuracy both on the race track and out on the open road, while also delighting drivers with its significantly enhanced directional stability and controllability right up to the limits of performance when driving in adverse conditions such as in the wet or snow."
The car's ability to juggle complete suitability for everyday use on the one hand and sheer driving pleasure and superb track performance on the other is down to the M xDrive system's central intelligent control capability. When the engine is first started, the new BMW M5 will be in all-wheel-drive mode (4WD) with Dynamic Stability Control (DSC) switched on. The driver is then able to vary the handling characteristics of the M5 by activating various driving dynamics modes, including a rear-wheel-drive mode with no DSC. In this 2WD mode, the new BMW M5 allows accomplished drivers to enjoy a purebred form of driving pleasure.
Hard at work under the bonnet of the new BMW M5 is the latest and most advanced version of the 4.4-litre V8 engine featuring M TwinPower Turbo technology. Output of 441 kW/600 hp and peak torque of 750 Nm (553 lb-ft) promise supreme propulsive power and formidable performance. The twinturbo V8 unit propels the new M5 from 0 to 100 km/h (62 mph) in a mere 3.4 seconds, for instance. The task of relaying the drive power falls to the new eight-speed M Steptronic transmission with Drivelogic, which teams up with the M xDrive system to transfer the high-revving engine's turbocharged might to the road to optimum effect in all driving conditions. The upshot of all this is that the new BMW M5 is not just the fastest of all the M5 models built since 1984, but the most nimble too.

Following a thorough overhaul, the 4.4-litre V8 engine with M TwinPower Turbo technology is now more potent than ever. The highrevving power unit in the new BMW M5 delivers its exceptional output of 441 kW/600 hp at 5,600 - 6,700 rpm, while the tremendous peak torque of 750 Nm (553 lb-ft) is on tap from just 1,800 rpm and remains constant all the way up to 5,600 rpm. Compared to the outgoing model, maximum torque has been upped by 70 Nm (52 lb-ft). The engine characteristics can be changed at the push of a button from the basic Efficient setting to either Sport or Sport Plus, resulting in even more willing response to movements of the accelerator.
The M engineers have implemented a raft of enhancements to endow the twin-turbo V8 with its phenomenal performance capabilities. These include newly developed turbochargers and a higher maximum injection pressure of 350 bar. This allows shorter injection times and improved atomisation of the fuel for sharper engine response as well as more efficient mixture preparation. Improvements have also been made to the lubrication and cooling systems, including an oil pan with a small front sump and indirect charge air cooling, which is more effective than the predecessor's equivalents despite taking up less space. The oil supply system uses a fully variable, map-controlled pump and has been designed for outings on the race track, where it can handle very high levels of longitudinal and lateral acceleration.
Modifications have likewise been made to the cross-bank exhaust manifolds for the new BMW M5. This has the effect of optimising the transmission of energy from the exhaust gas flows to the turbine wheels of the two turbochargers and ensuring the best possible gas-exchange cycle. By fitting a Helmholtz resonator between the two silencers of the dual-branch exhaust system, the M engineers have succeeded in reducing its weight. The sound from the flap-controlled exhaust system varies depending on the selected mode for the engine characteristics, while the M Sound Control button also allows drivers of the new BMW M5 to soften its acoustic presence.
