The BMW 7-Series is introducing several new models and accessories to reinforce the success it had in the previous year. Beside the already existing and new M Sport Pack being offered for all 7-series range for both regular and lengthened wheelbase, an optional xDrive AWD and a new 740d is also offered for the 2010 BMW 7-series.
Set for an introduction in the third quarter of the year, the BMW 740d will feature for the first time a new straight-six diesel powerplant equipped with TwinPower direct injection and twin-turbocharging technologies from the Bavarian carmaker.
The 3.0-liter engine is capable of 306hp (225kW) and 442lb-ft (600Nm) of top torque which it can consistently maintain in the engine speed range of 1,500 and 2,500rpm. These figures are sufficient enough to propel the car from 0-100km/h in 6.3 seconds and quickly reach a top speed of 250km/h which is electronically limited.
Even with these performance numbers, the car is still capable of a 34mpg (6.9L/100km) fuel economy and a lowered carbon dioxide emissions in the 181g/km level. Meanwhile, the 730d diesel
version receives a new BluePerformance exhaust particulate filtering system from the Bavarian carmaker for its 2010 model. The consequence of this addition is a reduction of nitric oxides to the emissions standard that will come with the introduction of the EU6 in 2014.
Fuel consumption is maintained at 34mpg (6.8L/100km) but emissions of carbon dioxide have been further lowered to the 178g/km level. The 2010 7- series will be equipped for the first time with the intelligent xDrive AWD of BMW, which will first be offered to the 750i and 750Li models and will later filter across the range in time.
The xDrive adapts the amount of torque channeled to either axle contingent on the traction levels of the four wheels and it attains this through an electronically controlled multiple-plate clutch. Furthermore, the operation of the xDrive is also dependent on the steering angle that the driver pre-determined.
When travelling regularly in a straight line, power is distributed 40-60 from font to rear with up to 80 percent of the drive power channeled to the rear axle in a curb. When the car gets over the curb the distribution reverts back to normal to provide optimum traction as it anticipates an acceleration as the car returns to a straight line driving position.
