The next-generation Mercedes-Benz CLS AMG has been spied testing out in the open. While the normal CLS has been caught a number of times, this is the first time that we see the high-performance AMG model strutting its stuff in public. Its side mirror indicators have the same design style as the E-Class sedan and the four oval tailpipes are an obvious indication regardless of the heavy camouflage.
The current CLS 63 AMG shares its engine with the previous-generation E 63 AMG and both make 378kW (514hp). If the same arrangement sticks then expect to see a 6.3-litre V8 installed and making 386kW (525hp). Driving the rear wheels should be Merc's Speedshift MCT 7-speed gearbox. Just like the E 63 AMG standard wheels should be 18-inches with the 19-inch size listed on the options menu.
Sales of the CLS 63 AMG should begin in 2011. Segment rivals will include the new Porsche Panamera Turbo and the high-performance version of Aston Martin's new Rapide. Audi will also enter this four-door coupe segment with the A7.
