Geneva preview: BMW 5-Series ActiveHybrid
February 26, 2010 § Leave a comment
BMW’s 5-Series ActiveHybrid concept has a similar powertrain to the 7-Series hybrid already launched, but instead of a V8, features a 300bhp straight-six cylinder petrol engine (as in the 535i) plus 40kW electric motor, stop-start system and regenerative braking. Unlike the 7-Series hybrid, it can operate in electric-only mode for short distances at low speeds, thanks to the more powerful motor. Fuel economy is around 10% better than that of the 535i, and is aided by a new sat nav feature which anticipates upcoming road conditions and primes the electric-drive system accordingly.
