The reportedly leaked images show an updated sedan with a revised front fascia, a new hood, and SL-inspired headlights with LED turn signals.

Are these the first official drawings of the 2011 Mercedes C-Class facelift? AutoBild says yes, but we're not entirely convinced.

Doubts aside, the pictures show an updated sedan with a revised front fascia, a new hood, and SL-inspired headlights with LED turn signals. Inside, the cabin has been completely revamped with a redesigned dashboard, a new instrument cluster, and an integrated COMAND display.

Under the hood, a variety of engines will be available. Notable choices will likely include the 225 kW (306 PS / 302 hp) 350 BlueEFFICIENCY, the 195 kW (265 PS / 262 hp) 350 CDI BlueEFFICIENCY and the 150 kW (204 PS / 201 hp) 250 CDI BlueEFFICIENCY. Of course, there will also be the C 63 AMG with a 6.3-liter (6208cc) V8 that produces 451 hp (336 kW / 457 PS) and 443 lb-ft (600 Nm) of torque.

The car will reportedly be introduced at the North American International Auto Show in Detroit, so expect to learn more in the coming months.

Head over to AutoBild to check out the rest of the images.
