These spy shots show Mercedes-Benz is preparing to expand the C-Class (W205) lineup by adding a plug-in hybrid version.

First we should remind you Mercedes-Benz will soon be offering a C 300 BlueTEC HYBRID with a 4-cylinder, 2.1-liter turbodiesel engine delivering 204 PS (150 kW) and 500 Nm (369 lb-ft) working together with a 20 kW electric motor. This hybrid C-Class will return 61.8 mpg US (74.3 mpg UK or 3.8 liters / 100 km) and should have CO2 emissions of less than 100 g/km.

There will also be this car, the C 350 HYBRID Plug-In which will feature a 4-cylinder, 2.0-liter turbocharged gasoline engine rated at 211 PS (155 kW) and 350 Nm (258 lb-ft) along with a 50 kW electric motor, enabling the model to return an impressive 78.4 mpg US (94.1 mpg UK or 3 liters / 100 km).

The C 350 HYBRID Plug-In will probably go on sale later this year.
