(This article translated automatically from Dutch) Famous people (Brad Pitt) or people important for BMW (large entrepreneurs, state folks, director of Al Gore's movie An incovenient Truth) can, from time to time, drive a Hydrogen 7, (certainly not belonging to the first group, I myself was once invited by BMW to drive a few miles in the surroundings of Amsterdam, an invitation I happily accepted and had a fine experience with it). But a lack of required infrastructure (production, distribution and hydrogen-stations network) makes it impossible to bring such a car on the market successfully now.
BMW has itself realised that and assumes of it over small ten years, however, successfully sell hydrogen models to be able. In the meantime old technique is improved, the manufacturer calls that Efficient Dynamics, and now a new middle-step is made: within two weeks the hybrid 7 is presented.

To save 15 percents fuel: the hybrid technique in BMW concept 7 series ActiveHybrid make it possible. The concept car, which makes one's debut over two weeks on the car fair of Paris, is mild hybrid on the basis of BMW 750i with a elektromotor built in the transmission. Those store brake energy in accumulators to feed electric consumers and eliminate the combustion engine at standstill shock-proof.
In the draft form 7 serials ActiveHybrid combine BMW strong V8-benzinemotor of 750i (300 kW/407 pk, 600 Nm) with a elektromotor which maximum 15 kW/20 pk and 210 provide Nm. The elektromotor has built in the petrol engine in the automatic transmission and supports at the accelerate. Thus the dynamic potential of 7 the serial is still further developed. Moreover the elektromotor replaces the dynamo, which is operated spoken normally by the combustion engine, and the start engine. Electric energy which is released at slowing down, is stored in powerful lithium ionaccu's with a high rise capacity. These have built in the luggage space.
Car starts stopper because the aandrijflijn of the concept 7 serial can ActiveHybrid arouse much electricity, can many functions in the car purely electrically be fed. This way it is occurred that precious fuel is converted directly into electricity. The function car starts stopper sale the combustion engine at standstill and integrates the engine automatically automatic and shock-proof at kicking in the accelerator.
Best or Hybrid the components of the hybrid system in the draft form 7 serials ActiveHybrid have been based on a technique which is developed by BMW in association with Mercedes-Benz. BMW ensures himself a harmonisation of the components, specific for the mark. BMW ActiveHybrid works according to the principle of construction toes, so that for each vehicle the most suitable components can be used. In the case of the concept 7 serials ActiveHybrid are that the elektromotor which has built in the transmission the lithium ionaccu's start and the described car Stop-functie. The concept 7 serials ActiveHybrid remove with that as mild hybrid just as well the bests hybrid technique up if full hybrid such as BMW concept X6 ActiveHybrid, which also on a elektromotor only can drive.
The concept 7 serials ActiveHybrid are v-spaakdesign provide with lichtmetalen 20-inchwielen with. To the front concerning the complete breadth of the front an aluminium strips has been assembled. These have an aerodynamic function. To the back aluminium returns in the form of an air slide and strip in the lid of the boot.
BMW ActiveHybrid is of technologies within EfficientDynamics, what stands for reduction of fuel consumption and emissies with conservation of file pleasure.
This problem: on holiday with the family in your SUV, to work with the same large car. Sustainable solution is not: two cars, one large and one small. Sustainable solution is not: complete year driving in your one large half-empty energy gurgling car. Sustainable solution is 1 car which can be large and small.
