Earlier this year at the Geneva Motor Show, BMW unveiled the 5 Series Hybrid Concept, the first 5er hybrid which will officially arrive at BMW dealerships in first quarter of 2011.
Today, the spy photographers at MotorAuthority managed to snap some shots of a production ready test mule being driven around Munich.
BMW Concept 5 Series ActiveHybrid features a drive system consisting of a 3.0 liter straight-six N55 gasoline engine with TwinPower Turbo technology, eight-speed automatic transmission, and electric drive. Integration of BMW ActiveHybrid technology in a sedan already extremely efficient with its “conventional” combustion engine reduces both fuel consumption and emissions once again by more than 10 per cent.
At the same time the electric motor offers a boost function, supporting the gasoline engine in generating particularly dynamic drive power for an even more sporting driving experience in the car. Drawing its energy from a high-voltage battery at the back of the car, the electric motor develops maximum output of 40 kW.
The drivetrain technology featured in the BMW Concept 5 Series ActiveHybrid allows all-electric, zero-emission motoring in city traffic. At the same time a special hybrid-based Auto Start Stop function offers additional efficiency by consistently switching off the combustion engine when stopping at the traffic lights, a road junction, or in congested traffic.
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.
Design wise, the ActiveHybrid 5 carries forward the sedan design lines, the only changes we expect are in the wheels area where specifically designed aerodynamics wheels will make their way into the final product.
Pricing has not yet been announced, but we expect the ActiveHybrid 5 to be positioned near the 550i top model.
