BMW Concept 7 Series ActiveHybrid

Posted by Published in Car Buying

It seems luxury automakers dig hybrids, but only for their flagships. Following Mercedes’ S400 hybrid, BMW has announced a new concept — to be displayed at the upcoming Paris Motor Show — that drops a hybrid powertrain jointly designed with Mercedes into its recently refreshed 7 Series sedan.

While the Mercedes-Benz S400 has a smaller engine and gets nearly 30 mpg, the 7 Series ActiveHybrid has a V-8 under its hood that’s teamed with a gentle hybrid system to return — get that — 15% better fuel economy. The current 750 gets a combined 18 mpg, so a 15% improvement would bring that up to 20.7 mpg. The price tag would be high for such a hybrid, so we assume fuel savings isn’t the primary goal

of the 7 Series ActiveHybrid.

At the same date, though, we wonder why BMW isn’t trying to produce a hybrid 1 or 3 Series.

Car buffs, however, might find that an intriguing option, as the V-8 plus gets a twin turbocharger, and its total ability when teamed to the electric motor is 427 hp and 597 pounds-feet of torque. The hybrid batteries are lithium ion.

We’d guess BMW will bring that to market at least in Europe. Mercedes has already said it will sell its S400 hybrid in both Europe and the U.S. in 2009.
