Our spies have sent us the first batch of photos with the 2015 Mercedes-Benz CLS63 AMG facelift, ahead of what is believed to be a late 2014 launch.

We have already seen the regular CLS and its more practical and sleeker Shooting Brake variant undergoing testing so naturally time has come to have a look at the range-topping AMG model. The vehicle will adopt redesigned front and rear fascias with big air intakes, in tone with all of the other recent AMG cars.

Under the hood we don't expect to find any major changes so the 2015 CLS63 AMG will probably come with the same twin-turbo V8 5.5-liter engine developing 557 HP (410 kW) and a peak torque of 531 lb-ft (720 Nm). It will run the 0-62 mph (0-100 km/h) sprint in 4.2 seconds or in 3.7 seconds if you opt for the 4MATIC version. The Shooting Brake derivative will be 0.1s slower in both cases.

For more money clients will be able to opt for the 4MATIC S-Model lifting output to 585 HP (430 kW) and 590 lb-ft (800 Nm). In this version the CLS will hit 62 mph in 3.6 seconds while the Shooting Brake will do it in 3.7 seconds. Regardless of the model, Mercedes-Benz will electronically limit speed to 155 mph (250 km/h).
