Default Hybrid variants of the Bmw 7-Series and X6 coming in 2009



Quote:
Hybrid variants of the BMW 7-Series and the BMW X6 will be started by BMW which will be scheduled to be on sale by the end of this year.

This report is confirmed by Ian Robertson, BMW Sales and Marketing Director, commenting that these two variants will be using varying hybrid systems. The 7-series will be utilizing a mild hybrid that permits the engine to shut down when braking or coasting while the accessories remain functional taking advantage of the electric motor.



On the other hand, the X6 would be coupled with a full hybrid system allowing it to run on pure electric or utilize a combination of its internal combustion engine and a bigger electric motor to propel the vehicle.



These two concept variants are currently on display at the NAIAS. The 7-Series concept is patterned after the 2009 model year and is equipped with a 4.4-liter bi-turbo V8 joined to a 20 hp electric motor that produces a remarkable 155 lb-ft of torque alone. The V8 which produces 400 hp and 450 lb-ft of torque will reduce fuel consumption by 15%.



Lithium-ion battery located at the boot of the car powers the electric motors while regenerative brakes channel energy back to the batteries. Meanwhile, the X6, which is equipped with the same 4.4-liter V8, comes with much less details, however, the German carmaker claims that it would generate 20% more fuel economy in contrast to identical V8 cars.


Considering that these two cars are still in their concept stages, changes to mechanics and detailing may be made prior to their showroom appearances. It is certain, however, that we will see these versions in dealerships very soon.

Default All-wheel drive BMW 7-Series due later this year

The later part of 2009 will see the introduction of AWD powertrains versions of BMW’s 7-Series, with the first models likely appearing after a debut at the Frankfurt Motor Show in September as 2010 models. The change is, for many, long overdue as the German competition has long offered AWD for their flagship vehicles.

AWD variants of the 7-Series will once again carry BMW’s xDrive tag and will initially be available only in the 407hp (303kW) 750i. Other models had been rumored to follow soon after, but the latest reports indicate only the 750i will have the option at all. There are not yet any plans for an AWD diesel 7-Series.

The 7-Series AWD features a high-tech torque distribution system, which sends 40% of the motive force to the front wheels and 60% to the rear when traveling in a straight line. But when the twisties start, up to 80% of drive is sent to the rear axle to maximize driving dynamics, with the percentage dependent upon steering angle, reports Auto Motor & Sport.

Another new feature will be the addition of an electronic ‘Hill-Descent’ control – the first for a luxury AWD saloon. The cars will also have slightly taller ride-heights and special underbody protection, reports Automotive News Europe.

In Europe, the AWD option will add roughly €2,500 ($3,500) to €2,800 ($4,000) to the price of the 7-Series, as well as an additional 110lb (50kg) onto its curb weight. Initial testing has shown that this extra weight will increase fuel-consumption over the standard RWD models by 1-2mpg (.2-.4L/100km).
