Mercedes-Benz S500 Plug-in Hybrid will debut in September

Mercedes-Benz has officially confirmed that the S-Class will get a plug-in hybrid variant in the 2014 lineup. The S500 Plug-in hybrid will make its debut in September at the 2013 Frankfurt Motor Show.

A while back, at an elaborate event in Germany, the S-Class was introduced, but the plug-in hybrid variant wasn’t even mentioned. Perhaps Mercedes was still considering a plug-in hybrid and hadn’t yet made a final decision.

Details are limited since the reveal hasn’t happened yet, but AutoCar UK does have some specifications to share. The S-Class PHEV will combine a V6 gasoline engine with an electric motor and a battery pack that is mounted in the trunk, and yes, some cargo capacity will be lost to the batteries.

Rumor also has it that the S500 plug-in hybrid will have CO2 emissions of 70 g/km in order to trump the Porsche Panamera S E-hybrid which is rated at 71 g/km and is currently the lowest emitter in the luxury saloon segment.

Combined fuel economy on the S500 PHEV is expected to be above 90 MPGe – likely on the European test cycle.
