The BMW 7-series


When the F01 was launched in 2008, there were three engine options, of which Malaysia only got two. Not unexpectedly, BMW Malaysia left out the 730d, choosing only to bring in the 740Li and 750Li. The 730d that we missed out on is powered by the 2,993cc N57D30 turbodiesel producing 245hp @ 4,000rpm and a delicious-sounding 540Nm @ 1,750-3,000rpm (i.e. all the time!). Besides featuring BMW’s now oft-trumpeted array EfficientDynamics goodies, the 730d can now be optioned with BluePerformance Technology, which slashes nitric oxide emissions to Euro 6 levels, due for implementation in 2014.
BMW also cleverly took the same N57 engine, slapped it with what they call TwinPower Turbo Technology (that’s how BMW call twinturbos these days), and came up with the 740d. The idea is simple, but the results are astonishing. Peak power is rated at 306hp, but max torque is a phenomenal 600Nm available between 1,500rpm and 2,500rpm. Put it simply, a mere twitch of your right foot sends enough torque to the rear wheels to twist the earth spinning the opposite direction. As a result, the two-tonne-plus 740d needs only 6.3 seconds to hit 100kph, with its top speed artificially limited to 250kph. Claimed FC is a highly respectable 6.9 litres/100km.

For the first time ever, BMW is making its xDrive electronic all-wheel drive system available in the 7-series. As of now, it would only be mated to the 4.4-litre V8 in the 750i xDrive and the 750Li xDrive. In the 750, the xDrive is set-up with a 60:40 rear-biased torque split, but the system re-routes up to 80% of drive to the rear wheels during cornering, a move that BMW claims to “ensure spontaneous steering behaviour precisely following the actual radius and course of the bend.”

Together with the 6.0-litre V12-powered 760i, these new variants have doubled the powertrain options for the BMW 7-series since its launch, all of which can now be specified with the M Sports Package available on the BMW 7-series for the first time. Unlike the M Sport Packages found in the 3 and the 5, which dress the respective cars up in understated aggression, the one designed for the 7 shouts it out with extra ‘bling-bling’ in the form of chrome-finish on the front and rear diffusers. Chrome finish in a sports kit? What were they thinking?

Other cosmetic touches with the M Sports Package is the optional exclusive Carbon Black Metallic paint, and 19″ alloys (20″ optional). The interior gets all the usual M-badged steerings, gearknobs and whatnots. Under the skin enhancements come in the form of electronics, which is the BMW Dynamic Drive system.
