BMW M550i xDrive Will Fill the Void of the M5 For Now
To coincide with the premiere of the new BMW 5 Series range, BMW M is bringing out a sporty BMW M Performance version of the world’s most successful business sedan. For the time being at least, the new BMW M550i xDrive will assume the status of range-topper in the new BMW 5 Series line-up. Boasting a mighty M Performance TwinPower Turbo engine, BMW xDrive intelligent all-wheel drive with rear-wheel bias and a bespoke M Performance chassis set-up, the new BMW M550i xDrive can be classed as both a four-door sports car and the most dynamic business sedan around. With its abundant torque reserves and high-revving characteristics, the V8 power unit serves up a matchless blend of supreme performance, wonderfully precise driving dynamics and uncompromised everyday usability. This all helps the new BMW M550i xDrive to set the pace in its segment and turn each and every drive into an exhilarating experience.
The new BMW M550i xDrive is the first BMW 5-Series M Performance model to be powered by a petrol engine, namely a specifically modified M Performance TwinPower Turbo eight-cylinder unit with a displacement of 4.4 litres. The V8 is equipped with two twin-scroll turbochargers and features the High Precision Injection direct injection system, Valvetronic fully variable valve timing and Double-VANOS variable camshaft control. This all adds up to an output of 462 hp at 5,500 rpm and peak torque of 650 Nm that can be summoned from just 1,800 rpm.
The state-of-the-art, high-performance engine comes with all the dynamic credentials expected of a BMW M Performance Automobile, propelling the BMW M550i xDrive from 0 to 100 km/h in 4.0 seconds, then on to an electronically limited top speed of 250 km/h. At the same time, the new V8 engine also demonstrates the exceptional efficiency of the M Performance TwinPower Turbo technology.
Drive transfer in the most powerful BMW 5-Series Sedan is, at present, handled by the standard-fit Steptronic Sport eight-speed transmission, which plays a significant role in the superb dynamics of the BMW M550i xDrive. The M Performance configuration of the shift modes has been tailored to the characteristics of the V8 engine, with distinctly sporty gear changes and more instantaneous downshifts across the entire rev range, and serves to enrich the thrilling driving experience.
For an even sharper sporting edge, the eight-speed Steptronic Sport transmission can also be operated using the shift paddles on the steering wheel. The transmission itself helps to cut fuel consumption and emissions thanks to its compact design, low weight and optimised efficiency.
The BMW xDrive all-wheel-drive system in the BMW M550i xDrive splits drive power between all four wheels as the situation demands – intelligently and with a rear-wheel bias. BMW xDrive is thereby key to delivering two intrinsic elements of the trademark M Performance driving experience under all conditions: superlative driving performance and extremely precise handling. And when the adaptive M Sport suspension (lowered by 10 millimetres) is added to the equation, along with either the standard 19-inch M light-alloy wheels in Cerium Grey metallic matt or the optional 20-inch light-alloy wheels (in an exclusive design, also painted in the Cerium Grey metallic matt finish), the result is tremendous handling stability and optimum traction, come what may.
M Sport brakes with brake callipers in Blue metallic and M badging, which combine outstanding stopping power with excellent feel.
