Mercedes-Benz’s next generation S-Class will include two hybrid models, a gasoline and a diesel version, and a plug-in hybrid model will join the lineup “soon.”

The new S 400 Hybrid, which combines a V6 gasoline engine with an electric motor and Li-ion battery pack, will deliver combined fuel economy of around 37 mpg, a reduction of 20% compared to the previous model. Carbon dioxide emissions are 147 grams/km, a new record in this vehicle segment, according to Mercedes.

The S 300 BlueTEC Hybrid features a 2.2-liter four-cylinder diesel engine and a 15 kW electric motor.

“The new S-Class achieves consumption and emissions figures that only a few years ago seemed utopian, even for executive cars,” said spokesman Thomas Weber, “and this is just the start of our ‘Green Leadership’ initiative: soon to be followed by the S 500 Plug-In Hybrid – the first S-Class with a fuel consumption lower than four liters per 100 km (59 mpg).”

Mercedes has not announced a launch date or any other details for the PHEV model.
