For the 2008 model year, Mercedes-Benz introduced the CLK63 AMG Black Series. Available exclusively as a hardtop coupe, the CLK 63 Black featured extensive weight saving in order to increase the car's performance, including the removal of the rear seats. Powered by a 500hp naturally aspirated 6.2L V8 engine and paired to a 7 speed automatic transmission, the CLK 63 Black also features numerous upgrades to the suspension and drivetrain in order to improve performance. Production of the CLK63 AMG Black Series ended in 2009, with a total of 500 examples built.
