BMW 5-Series GT is like those big mobile phones which are very geeky and offer a huge number of functions, but has no style! Now to make it even more nerdelicious, BMW announced that all variants of the 5er GT can be had with their sophisticated all-wheel-drive system called the xDrive. They are also offering this for the V8 diesel variant of the 7-series (740d).
Making their debut at 2010 Beijing Auto Show, the BMW 530d xDrive Gran Turismo and the BMW 550i xDrive Gran Turismo feature a permanent, electronically masterminded all-wheel drive ensures the appropriate distribution of drive power front-to-rear in every situation. Later in summer, you can have the 530d diesel and the 535i turbo with the same AWD treatment.
As mentioned earlier, the 740d model too can be had with xDrive system. However we cannot think of a good reason why a diesel-powered luxury saloon should need four-wheel-drive! You know it just isn’t worth the extra pay.
BMW says that their xDrive system “enhances driving stability also in dynamic bends by recognising even the slightest tendency to over- and understeer at an early point and taking appropriate counter-action right away.” But if you got one of these models do not think you can take on the Kalahari desert in it! Because as we’ve already seen with the BMW X range of high-riding SUVs, the xDrive system is mainly designed to give you better dynamics on the road, and it doesn’t really work off it.
After the pictures, you will find the performance figures and technical details for all of these new xDrive models in BMW’s official press release…
BMW 550i xDrive Gran Turismo is powered by a supreme V8 boasting BMW TwinPower Turbo Technology and High Precision Injection. Displacing 4.4 litres, this outstanding eight-cylinder delivers maximum output of 300 kW/407 hp all the way from 5,500 – 6,400 rpm as well as peak torque of 600 Newton-metres/442 lb-ft maintained consistently between 1,750 and 4,500 rpm.
This superior torque coming in at an early point and maintained throughout a broad speed range is now converted into supreme driving dynamics even more precisely and in even more superior style through BMW xDrive technology, accelerating the car to 100 km/h in 5.4 seconds. Top speed is cut off by the engine’s electronic control unit at 250 km/h or 155 mph. Average fuel consumption in the EU test cycle, finally, is 11.8 litres/100 km, equal to 23.9 mpg imp, with CO2 emissions amounting to 275 grams per kilometre.
The BMW 550i xDrive Gran Turismo is the first model to combine such intelligent all-wheel drive with the supreme driving dynamics, motoring comfort and efficiency of an eight-speed automatic transmission.
The straight-six diesel engine in the BMW 530d xDrive Gran Turismo likewise represents the latest state-of-the-art in BMW engine development. Displacing 3.0 litres, the engine comes with an all-aluminium crankcase, its turbocharger system featuring variable intake geometry ensuring a superior surge of power and performance tailored harmoniously to all kinds of driving conditions.
Fuel is delivered by the latest generation of piezo-injectors operating at a maximum pressure of 1,800 bar. This gives the engine maximum peak output of 180 kW/245 hp at 4,000 rpm, with torque reaching its peak of 540 Newton-metres/398 lb-ft at just 1,750 rpm.
Benefiting from this kind of power, the BMW 530d xDrive Gran Turismo accelerates from a standstill to 100 km/h in 6.9 seconds and reaches a top speed of 235 km/h or 146 mph.
At the same time the car combines this sporting performance with average fuel consumption of 6.9 litres/100 kilometres, equal to 40.9 mpg imp, in the EU test cycle. The CO2 rating, finally, is 183 grams per kilometre.
The BMW 535d xDrive Gran Turismo features a second even more powerful representative of the new generation of straight-six BMW diesels. Boasting BMW TwinPower Turbo Technology and common rail direct fuel injection, the all-aluminium power unit in this equally outstanding model develops maximum output of 220 kW/300 hp at 4,400 rpm as well as peak torque of 600 Newton-metres/442 lb-ft maintained consistently between 1,500 and 2,500 rpm.
The straight-six gasoline power unit in the BMW 535i xDrive Gran Turismo combines turbocharging, High Precision Injection and variable VALVETRONIC valve management with one another. This unique combination gives the BMW TwinPower Turbo an extremely spontaneous and direct response to the gas pedal. This outstanding response is then further optimised by VALVETRONIC valve management as well as the turbocharger system applying the twin-scroll principle both in the exhaust manifold and the turbocharger to separate the ducts and flow channels of three cylinders at a time.
With its high-tech injection nozzles, High Precision Injection doses fuel with maximum precision, delivering the fuel required into the combustion chambers at a pressure of up to 200 bar.
Displacing 3.0 litres, this outstanding six-cylinder delivers maximum output of 225 kW/306 hp at 5,800 rpm. Peak torque of 400 Newton metres/295 lb-ft, in turn, comes between 1,200 and 5,000 rpm.
With the top-of-the-range BMW 750i xDrive and BMW 750Li xDrive already introducing BMW’s intelligent all-wheel-drive system in the 2010 model year in the 7 Series, the BMW 740d xDrive is making its appearance in September.
With its all-aluminium power unit, the BMW 740d xDrive boasts BMW TwinPower Turbo Technology as well as common-rail direct fuel injection with its piezo-injectors operating at a pressure of up to 2,000 bar. Maximum output, as a result, is 225 kW/306 hp, with peak torque of 600 Newton-metres/442 lb-ft maintained consistently between 1,500 and 2,500 rpm.
