Last week at the Paris Auto Show 2008, BMW threw their hat in the hybrid luxury car ring with the introduction of the new BMW ActiveHybrid7, the 750i’s adaptation of a mild hybrid. Ultimately [and wisely] refusing to sacrifice famed-BMW performance for fuel efficiency, the 7-Series hybrid comes with a 400-hp, 4.4L twin-turbo engine, mated with an 8-speed automatic transmission and a 50kW electric motor. Designed to compete with similar green luxuries like the Mercedes-Benz S400 BlueHybrid and Lexus LS600hL, the BMW 7-Series Active Hybrid isn’t exactly geared towards the average hybrid buyer.

Technically considered a “hybrid” vehicle, the ActiveHybrid7’s electric motor is fully integrated into the gearbox, allowing it to provide auxiliary power as an electric generator only. While this fact still enables the ActiveHybrid7 to conserve energy, the electric motor is not engineered to allow full electric drive. What’s more, despite vaguely impressive boasts that the ActiveHybrid7 is 15% more fuel efficient than the standard 750i, translating that into hard data eliminates some of the romance. Allow me to demonstrate:
Currently, the 2008 BMW 750i features an EPA fuel consumption average of 15 mpg city/23 mpg hwy.
So, if 15% of 15 is 2.25, and 15% of 23 is 3.45, then the ActiveHybrid7 should average about 17.25 mpg city/26.45 mpg hwy. No, please, hold your applause.
Now granted, I did major in English in college, as opposed to advanced mathematics, so there could be a flaw in my formula, but I’m not inclined to think so. If you couple those numbers with the ActiveHybrid7’s understated exterior badging, you have to admit, something seems rotten in the state of Deutschland.
