The Mercedes-Benz S-Class Coupe has been caught wearing only light camouflage while winter testing in Sweden.

Seen in concept guise at the Frankfurt motor show in September, and spied in S63 AMG trim near Germany’s Nurburgring, the replacement for the seven-year-old CL-Class is due to arrive locally in late 2014.

Snapped by CarAdvice’s spy photographers, the Mercedes-Benz S-Class Coupe will adopt the larger-displacement petrol engines of its four-door sibling, teamed to seven-speed automatic transmissions.

Earlier this year, Mercedes-Benz Australia corporate communications manager David McCarthy told CarAdvice the S-Class coupe range will consist of the S500, S600, S63 and S65. In Australia, the S-Class sedan's line-up of petrol engines comprises the 335kW/700Nm 4.7-litre twin-turbo V8-powered S500 and the flagship S63 with its 430kW/900Nm 5.5-litre twin-turbo V8.

The S-Class Coupe will also be the only S-Class variant to be offered in S65 AMG specification, with drive coming from the company’s 463kW/1000Nm 6.0-litre twin-turbo V12.

Expected to command a circa-$50K price premium over the S-Class sedan, which costs $285,000 for the S500, and $385,000 for the S63, the Mercedes-Benz S-Class Coupe will be followed by an S-Class convertible.
