The BMW Concept 7 Series ActiveHybrid a V8-cylinder petrol engine and an electric drive in a mild hybrid concept will be linked intelligently together. The drive concept of the study allows for improved driving dynamics while reducing fuel consumption and emissions by 15 percent in the EU test cycle compared to a vehicle with pure internal combustion engine. This requires the use of BMW ActiveHybrid technology no limitations on the practicality and the model-specific characteristics of a BMW 7 Series.
The concept study represents the combination of ride comfort, visual presence and sovereignty of a BMW 7 series with trend, efficiency-optimized drive technology by BMW ActiveHybrid technology. This implies the option to enrich by BMW Active Hybrid, the brand’s sheer driving pleasure at an additional facet. The implementation in a vehicle of this segment leads to a new perception of hybrid technology: In the configuration developed by BMW it causes significant efficiency gains efficiency without any renunciation, dynamics, safety and comfort.
The drive technology of the BMW Concept 7 Series Active Hybrid consists of a V8 petrol engine with Twin Turbo and High Precision Injection, based on the drive of the BMW 750i. There he has an output of 300 kW/407 hp and maximum torque of 600 Newton meters. Now it is combined with a fully integrated into the gear housing electric unit with a capacity of 15 kW and a torque of up to 210 Newton meters.
Under the mild hybrid concept increases the electric drive, the dynamic potential of the eight-cylinder gasoline engine in the character of the BMW 7 Series appropriate manner, by supporting the acceleration of the vehicle contributes. In addition, the electric unit is provided by brake energy regeneration current to supply the electrical loads on board. Thus, the direct conversion of fuel into electrical energy is minimized and maximized for conversion into driving dynamics available torque.
The V8 petrol engine is ideal for both driving dynamics and on efficiency-oriented vehicle concept. He is the world’s only eight-cylinder gasoline engine, the turbo charger to save space are arranged in the V-space between the cylinder banks, and also the most efficient engine in its class. Developed for the concept car hybrid components are based on a technology that is designed as part of the hybrid co-operation between BMW and Daimler. The hybrid co-operation successfully develops components for hybrid drives including power electronics and high-voltage batteries. The BMW-specific interpretation of the hybrid drive system is also protected.

BMW ActiveHybrid is based on a modular principle which allows accordance with the strategy “Best of Hybrid” to integrate the optimum components for different vehicle segments. In the BMW Concept 7 Series ActiveHybrid components used – mild hybrid transmission and eight-cylinder gasoline engine supplement – is just as ideal as full hybrid transmission and eight-cylinder petrol engine in the BMW Concept X6 Active Hybrid. The compact, replaced in the gearbox integrated e-conventional machine, directly from the engine-driven generator and the starter. Electrical energy is produced by Brake Energy Regeneration with a unique efficiency and high efficiency without impairing the drive torque of the motor.
The integrated power electronics enable unmatched compact and safe arrangement of the hybrid components. A powerful, integrated package-compliant in the luggage lithium-ion battery stores the energy generated and supplied the electrical system. Its high storage capacity enables the potential of regenerative braking system optimally. BMW Active Hybrid produces more electric power from less fuel.
With the increased electrical power available, additional vehicle functions are operated purely electrically. The Auto Start Stop function to prevent idling of the combustion engine in conjunction with Active Hybrid technology in a particularly convenient expression is available.
The BMW Concept 7 Series ActiveHybrid demonstrates the integration of BMW ActiveHybrid technology in a luxury sedan in the BMW 7 Series. All hybrid components are arranged package compliant. E-machine and power electronics – are not visible from outside – integrated into the gear housing. A specially designed hollow aluminum cargo space illustrates the compact design of the lithium-ion batteries.
The front of the BMW Concept 7 Series ActiveHybrid shows the typical range for the natural presence, especially through the large, upright BMW kidney underlined. Sches specific feature of the concept vehicle is a whole over the width of the front-reaching aluminum strip below the flag carrier, the contributes as an air guide for optimizing the aerodynamics. The lower air intake is covered in the middle of Alumiumband. They are divided horizontally by the outwardly tapering foothills of Alumiumbands. At the outermost edges of the air intake vents are positioned fog lights, consisting of seven LED units.
In side view, the sporty and elegant lines of the BMW 7 Series is highlighted by 20-inch alloy wheels in V-spoke design. The rims are painted in body color. The painting of the vehicle and the rim in the color Blue Metallic Water serves as a recognition feature for particularly efficient concept cars from BMW.
At the rear of the BMW Concept 7 Series ActiveHybrid symbolize a further air guide made of aluminum and exhaust tailpipes with new contours, the innovative drive concept. Analogous to the front end extends into the rear integrated aluminum strip over the entire vehicle width. At the same time it forms the upper frame of the outlets are arranged far outboard of the exhaust system. The strikingly broad and flat contour of the outlets wins by an additional horizontal brace a appearance.http://www.themhshow.com/bmw/bmw-concept-7-series-active-hybrid.html
