New CLS features softer design lines for this 4-door coupe. The new CLS will likely make its debut at the Paris motor show this fall.

In these spy shots here, taken in Stuttgart, we get to see the upcoming 2012 Mercedes-Benz CLS completely uncovered.

We've already been able to spot the flatter nose of the new CLS in previous spy photos, a styling cue borrowed from the SLS Gullwing, but seeing the CLS in the bare like this one can more easily take in its design as a whole and spot things like its slight resemblance to the VW Passat CC.

New styling cues for the CLS are a fresh set of headlights with LED running lights. At the back, the wrap-around taillights seem more stretched towards the center of the rear end. There is the flattened nose too and the overall shoulder line seems to make the CLS stand a little more upright than its predecessor.

Petrol/gasoline engines for the new CLS will include Mercedes-Benz's 3.5 liter V6 with 306 PS (225 kW / 301 bhp) and a 435 PS (320 kW / 429 bhp) 4.7 liter twin-turbo V8. On the diesel side will be a 204 PS (150 kW / 201 bhp) four-cylinder and a 3.0 liter V6 diesel with 252 PS (185 kW / 248 bhp).

A CLS 63 AMG will follow, of course, powered by the brand's 5.5 liter, twin-turbo V8 churning out 544 PS (400 kW/536 bhp) and 800 Nm (590 lb-ft) of torque.

The new CLS will likely make its debut this fall at the Paris motor show.
