Mercedes announced their new S550 plugin hybrid four door will go on sale in the States in 2015, beating Rolls-Royce EV, Bentley Mulsanne Hybrid, and other luxury makers to the market.  The car will debut at Paris Auto Show in October.

Like all hybrids, Mercedes had to find a place to stash the electric motor and batteries.  In this case, the motor is mounted within the car’s seven speed automatic transmission.  The batteries are in the trunk, reducing storage there by 25% to 13.9 cu ft.

The gasoline engine is a 3.0l V6 rated at 328 hp and 351 lb-ft of torque.  Combined, the car has 447 lb ft of torque, less than the regular S550’s twin turbo 4.7l V8.  The car will drive 20 miles on electric only and will do a combined cycle consumption of 84 mpg (U.S.) on the European test cycle.  Also relevant to Bentley are Mercedes’ plans to bring this power train to the GL and ML class SUVs in the future.  Bentley has confirmed plans to offer a hybrid version of its new SUV.
