The BMW Concept 5-Series ActiveHybrid, which is set to debut at the Geneva Motor Show, will be powered by a straight-six gasoline TwinPower turbocharged engine mated to an eight-speed automatic transmission and an electric hybrid system.
With this car, BMW is aiming for a mild hybrid that reduces emissions and fuel consumption by up to 10%, which isn't impressive but it may be just enough to appeal to consumers.
Production will start in a year. Aside from greening up BMW's image, the hybrid system also boosts the power. It delivers a sportier experience than could be found in thriftier hybrids
BMW said that with the high torque available from a standstill due to the electric motors, the "interaction of the two drive systems ensures extremely spontaneous and dynamic acceleration whenever required."
This concept car also is illustrative of the next generation of BMW's ActiveHybrid technology. Due to its modular design, the car could be adapted to other models and segments.
Similar to other hybrids, the 5-Series Concept ActiveHybrid uses energy regeneration through both overrun and under braking to recapture kinetic energy and turn it back into electricity.
Like BMW's existing EfficientDynamics method of aggregating many small efficiency-boosting technologies to produce tangible overall results, the 5-Series ActiveHybrid Concept will also use a high-voltage battery to power its on-board network and accessories.
This includes climate control, audio and navigation, and auto stop-start. BMW asserts that the 5-Series ActiveHybrid can result to fuel savings at both lower speeds and higher speeds due to its design to operate under a wide range of engine RPMs and loads. Conventional hybrids could only do so at lower speeds.
