From the official Press Release:

Exterior design

The BMW Concept 7 Series ActiveHybrid is based in its concept and fundamental design on the new BMW 7 Series.

The dynamic proportions of the car are clearly expressed by its long wheelbase, the long and sleek engine compartment lid, the short front overhang, the passenger compartment moved far to the rear, and the low roof ine.

The BMW Concept 7 Series ActiveHybrid adds specific design features both at the front and the rear to enhance this characteristic look to an even higher level.

"The close match of the production model and the concept car symbolises BMW’s claim to offer the potential of ActiveHybrid technology within BMW’s existing portfolio of models."

All hybrid components are fitted and arranged according to the car’s specific package.

The electric motor and the power electronics are integrated in the transmission housing, where they cannot even be seen from outside.

A specially designed trough in the luggage compartment made of aluminium accommodates the compact lithium-ion battery.

The front end of the BMW Concept 7 Series ActiveHybrid is characterized by the large, upright BMW kidney grille.

A specific feature of the Concept Car is the aluminium band stretching across the entire width of the front end beneath the numberplate and serving to provide a controlled flow of air for optimum aerodynamics.

The lower air intake scoop is covered in the middle by this aluminium band, the openings to the left and right refl ecting the contours of the headlights just above and split horizontally by the aluminium band tapering out towards the sides.

The foglamps fitted at the extreme edge of the air intake openings are made up in each case of seven LED light units.

Seen from the side, the sporting look is underlined by 20-inch light-alloy rims in V-spoke design.

The rims are finished in body colour, the Blue Water Metallic paintwork on the car and rims serving as a particular sign of distinction for BMW’s maximum-efficiency Concept Cars.

At the rear of the BMW Concept 7 Series ActiveHybrid an additional air guidance element made of aluminium and exhaust tailpipes with new contours symbolise and round off the innovative drive concept.

As an analogy to the front end of the car, the aluminium band integrated in the rear apron stretches across the entire width of the vehicle, at the same time forming the upper surround on the exhaust tailpipes both positioned far to the outside.

The unusually wide and flat contours of the tailpipes, finally, form an almost multiple-plate structure thanks to the additional horizontal crossbar.

Technical features

The powertrain of the BMW Concept 7 Series ActiveHybrid is based on a modular concept and consists of components – the mild hybrid transmission and the eight-cylinder gasoline engine – which supplement each other in the same manner as the full hybrid transmission and the eight-cylinder petrol engine in the BMW Concept X6 ActiveHybrid. based on a modular concept

The drivetrain of the BMW Concept 7 Series ActiveHybrid is made up of a V8 gasoline engine with Twin Turbo and High Precision Injection based on the power unit of the BMW 750i.

Maximum output of the conventional engine in the regular production model is 300 kW/407 hp, with peak torque of 600 Newton-metres or 442 lb-ft.

Now this engine is combined with an electric motor integrated in the transmission housing, developing maximum output of 15 kW/20 hp and peak torque of 210 Nm/155 lb-ft.

A high-performance lithium-ion battery integrated in the luggage compartment in accordance with the package of the car saves the energy generated and supplies power to the on-board network.

With the mild hybrid concept, the electric motor boosts the dynamic driving potential of the eight-cylinder gasoline, giving the car even more dynamic acceleration.

Using Brake Energy Regeneration, the electric motor supplies electric power to the power-consuming items on board the car, minimising the direct conversion of fuel into electrical energy and maximising the drive power available for enhanced driving dynamics.

The hybrid components developed for the Concept Car are based on technology created by BMW and Daimler in their cooperation on hybrid drive systems.

In this joint venture the two manufacturers have successfully developed components for hybrid drive including the power electronics and high-voltage batteries.

Additional functions in the car are run completely under the electric power supply. The Auto Start Stop function preventing the combustion engine from running in the idle mode is particularly helpful and comfort-oriented in this case thanks to the combination with ActiveHybrid technology.
