Munich. The two new top models in the BMW X family exude a supreme presence with a corresponding performance. Like the drive and suspension technology, the model-specific design features of the new BMW X5 M50i and the new BMW X7 M50i have passed through a consistent design process that has resulted in an absolutely breath-taking motoring experience. Moreover, the exclusive nature of the new 8-cylinder models is reflected in the extremely high quality of their standard equipment. New V8 engine with outstanding power and characteristic sound. The 4.4 litre drive unit of the new BMW X5 M50i and the new BMW X7 M50i emphasise the characteristic features of the 8-cylinder engines in terms of power development and torque to an outstanding degree. The new V8 engine turns in a very impressive level of performance - whether you prefer cruising calmly and confidently at low engine speeds or pulling out all the performance stops and laying down some sporty acceleration manoeuvres. Several components have been upgraded since the previous engine version; these include the crankcase, cylinder barrels, pistons, crankshaft and cylinder head - and above all, the freshly updated BMW TwinPower Turbo technology.
The turbochargers positioned between the cylinder banks in the V compartment have been enlarged, while the direct petrol injection performs at a new maximum pressure level of 350 bar. The technology package also includes the newest versions of the fully variable VALVETRONIC valve control and variable double VANOS camshaft control. The new V8 engine responds with great sensitivity to every movement of the accelerator pedal. The engine already generates its maximum torque of 750 Nm at 1 800 rpm - and it remains available up to an engine speed of 4 600 rpm. Accordingly, the power output is as strident as you would expect it to be. The maximum value of 390 kW/530 hp is activated between 5 500 and 6 000 rpm. As a result, the new BMW X5 M50i is able to accelerate from zero to 100 km/h in 4.3 seconds. The new BMW X7 M50i completes its standard sprint in 4.7 seconds. This supreme power development is accompanied by an impressive sound progression that is generated by the standard M sport exhaust system.
Using the driving experience control, the driver can choose between an extremely sporty or a more comfort-oriented mode. The sheer bandwidth of the engine’s character then becomes all the more obvious. In the SPORT and SPORT PLUS modes, not only is the characteristic curve of the accelerator pedal configured for a dynamic driving style, but the power development and remarkable sound characteristics of the V8 engine are too. 8-speed Steptronic sports transmission, BMW xDrive and M sports differential for thrilling performance. The performance features of both of these thoroughly sports-oriented SAV models are supported by the rather specific nature of the power transmission. The new V8 engine is combined as standard with an 8-speed Steptronic sports transmission, characterised by highly dynamic gear shift properties. Shift paddles are mounted near the steering wheel for manual control of the choice of gear. The Launch Control function enables traction-optimised acceleration with maximum dynamic performance from standing.
The latest version of the BMW xDrive system distributes the engine torque between the front and rear wheels in a manner that enables it to adapt quickly and precisely to the road conditions. The intelligent all-wheel drive system increases the agility and supreme traction of the new BMW X5 M50i and the new BMW X7 M50i as much as it enhances the driving stability in all weather and road conditions. These sporty characteristics are also supported in highly dynamic driving situations by the rear-wheel emphasis of the system’s design. In addition, the standard equipment of the new BMW X5 M50i and the new BMW X7 M50i also includes an M sports differential. The electronically controlled differential lock in the rear bevel gears limits the rotational speed balancing between the wheel on the innermost side of a bend and that on the outermost side and enables highly dynamic acceleration when exiting a bend. In addition, the M sports differential, which is interconnected with the DSC (Dynamic Stability Control), optimises traction and power transmission when driving on loose terrain and when different road friction values exist between the right and left rear wheels.
