In 2010 at Geneva Motor Show, BMW unveiled the first 5 Series hybrid vehicle. The ActiveHybrid 5 Concept was a preview of the production model that will come to market in Spring of 2012. Prior to its soft launch later this year, new spy photos emerge from Germany.
During the first quarter of 2012, ActiveHybrid 5 will be launched in five major markets, including the United States. This will be the first hybrid from BMW with an in-line six-cylinder engine.
The drive system featured in the BMW Concept 5 Series ActiveHybrid consists of 3.0 liter straight-six N55 gasoline engine with TwinPower Turbo technology, eight-speed automatic transmission, and electric drive. 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.
The ActiveHybrid 5 should therefore, despite its more than 300 horsepower, deliver a standard fuel consumption of around 8 liters per 100 kilometers.
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.
The production ActiveHybrid 5 sports a similar design as the “regular” 5 Series sedan. One visible change comes from different wheels options designed to improve the aerodynamics. A slightly revised front grille and fascia will distinct the 5 Hybrid from the standard version.
When it does debut, the 5 Series hybrid will join the 7 Series ActiveHybrid and X6 ActiveHybrid in BMW’s hybrid lineup. We anticipate base price to be slightly higher than the gasoline-powered 5 Series sedan.[Source: BimmerToday ]
