Here's the actual world debut of the Mercedes-Benz C Class at the Detroit Auto Show. The carmaker staged a special event featuring former Destiny’s Child member Kelly Rowland.

The new C-Class is larger, and up to 100kg lighter than the outgoing model thanks to the aluminum hybrid body with fuel consumption dropping by 20 percent. It will be available from September 2014 with two gasoline powertrains.

The C 300 4MATIC with a 2.0-liter turbocharged direct-injection in-line four-cylinder engine producing 235 hp and 273 lb-ft (370 Nm) of torque and a C 400 4MATIC with a 3.0-liter turbocharged direct-injection V6 churning out 329 hp and 354 lb-ft (480 Nm) of torque.

Five four-cylinder petrol engines rated at 154hp (156PS) to 235hp (238PS) will also be available, including the special C 180 ECO Edition model. A six-cylinder petrol engine rated at 329 hp (333PS) will follow later, as well as the C 300 BlueTEC Hybrid pairing the 201hp 2.1-liter diesel with a 20kW (27hp) electric motor for an average fuel consumption of 3.9 l/100 km (60.3 mpg US).
