Taking this approach, BMW is consistently continuing the development of hybrid technology according to a modular principle (best of hybrid), thus offering the optimum rendition of BMW ActiveHybrid technology for each concept and vehicle segment.
In accordance with the BMW EfficientDynamics development strategy, this ensures highly effective and practical use of hybrid technology for the reduction of both fuel consumption and emissions.
Also in the BMW Series Sedan segment: the BMW among hybrids combines supreme dynamics with maximum efficiency.
The combustion engine is supported in the BMW Concept 5 Series ActiveHybrid by an electrical drive system developed specifically for this model and arranged in compact dimensions between the straight-six combustion engine and the automatic transmission. Drawing its energy from a high-voltage battery at the back of the car, the electric motor develops maximum output of 40 kW.
An automatic clutch connects the gasoline engine and the electric motors.
Due to the particularly high level of torque generated from the start through the electric motors, the interaction of the two drive systems ensures extremely spontaneous and dynamic acceleration whenever required.
Perfectly integrated, precisely controlled: high-voltage battery supplying power to both the electric motor and the on-board network.
In overrun and when applying the brakes, the electric drive systems acts as a generator developing electric power fed into the high-voltage battery. This converts kinetic energy otherwise wasted as heat in the brake system into electric power saved for subsequent use.
Such energy obtained without any further consumption of fuel may then be used to generate drive power or operate electrical functions in the car.
This principle is the same as that of Brake Energy Regeneration already applied in BMW's current production models, with the level of electrical energy generated by the electric motor being significantly greater and the increase in efficiency correspondingly higher.
