Recently caught undergoing cold weather testing, the redesigned model is heavily camouflaged but we can see it will have a stylish front fascia that echoes the sedan. Bigger changes occur aft of the A-pillar as the coupe adopts door-mounted mirrors, a rakish windscreen, and a stylish greenhouse that echoes the C and S Class Coupes. Other notable highlights include a gently sloping roof and wraparound taillights.
Our spies couldn't get close enough to snap interior photos but the cabin will likely echo the sedan and feature higher quality materials as well as a modern design. Nothing is official but the car will likely have a new steering wheel with touch-sensitive control buttons and a digital instrument cluster with 12.3-inch displays.
Engine options will carryover from the coupe's four-door counterpart, so expect to see an assortment of different options including a turbocharged 2.0-liter four-cylinder that develops 241 horsepower. European customers can also expect a handful of diesel options including a 2.0-liter four-cylinder with 195 hp and a six-cylinder with 258 hp.
