The BMW Concept 5 Series ActiveHybrid is a concept which is based on the new BMW 5 Series Sedan. This latest concept car presents for the first time the next generation of BMW ActiveHybrid technology and provides a predominantly good rendition of the new BMW 5 Series Sedan in all its dynamic, efficient and innovative qualities. Simultaneously, it also represents the ongoing development of the BMW ActiveHybrid X6 and the BMW ActiveHybrid 7 with their drivetrain technology already in production.
The drive system featured in the BMW Concept 5 Series ActiveHybrid consists of a straight-6 gasoline engine with TwinPower Turbo technology, 8-speed automatic transmission, and electric drive. The combustion engine is supported by an electrical drive system developed expressly for this model and arranged in compact dimensions among the straight-6 combustion engine and the automatic transmission and drawing its energy from a high-voltage, the electric motor develops maximum output of 40 kW.
Disparate conventional hybrid, by combining the combustion engine and the electric motor, both the BMW ActiveHybrid X6 and the BMW ActiveHybrid 7 are able to offer considerably lower fuel consumption and emission ratings also at higher speeds. This is made feasible by the power electronics that masterminds the interaction of the combustion engine and the electric motor, optimizing the overall efficiency of the drive system as a group.
A further unique feature of energy management in the new BMW Concept 5 Series ActiveHybrid is the car’s capability to adjust its operating strategy not just to the current but also to future driving conditions. To do this, the power electronics from the start evaluate data indicating a likely change in exterior conditions or the driver’s wishes and prepare the components in the drivetrain and the car’s electronic system for a possible change in requirements.
