Mercedes-Benz has revealed the 2014 CLS 63 AMG and Shooting Brake which will make their debut next week at the Detroit Motor Show.

Aside from launching the updated E63 AMG, Mercedes has announced today the 2014 CLS 63 AMG which carries over the same engine upgrades as the range-topping E-Class model. The V8 5.5-liter bi-turbo is now capable of producing 557 HP (410 kW) at 5,500 rpm and 720 Nm (531 lb-ft) between 1,750 rpm and 5,250 rpm. The four-door coupe completes the 0-62 mph (0-100 km/h) run in 4.2 seconds while the Shooting Brake needs an additional 0.1 seconds. The 4MATIC versions do it in 3.7 and 3.8 seconds, respectively.

The updated CLS lineup will also be offered in the 4MATIC S-Model variant which lifts output to 585 HP (430 kW) at 5,500 rpm and 800 Nm (590 lb-ft) between 1,750 and 5,000 rpm. It enables the coupe to hit 62 mph in 3.6 seconds and the Shooting Brake in 3.7 seconds. All models have an electronically limited top speed of 155 mph (250 km/h).

The seven-speed AMG SPEEDSHIFT transmission is offered with four modes: Controlled Efficiency (C), Sport (S), Sport Plus (S+) and Manual (M). The S-Model is fitted with a rear-axle differential lock and comes with red painted calipers, while on the inside there's a black Nappa leather steering wheel, a revised AMG instrument cluster and grey contrasting stitching.

The rear-wheel drive model is slated to go on sale in April, followed by the all-wheel drive version and the S-Model in June.
