The second generation of the CL is the W215-chassis coupé of 1999–2006. It is based on the Mercedes-Benz S-Class (W220) (which was launched in late 1998 in Europe), though it rides on an shorter wheelbase. The CL's front fascia of four oval headlights is similar to that of the W210 and W211 E-Class. The CL is offered as four models: the V8-powered CL 500, the NA V8-Powered CL55 AMG, the supercharged V8-powered CL55 AMG, the NA V12-powered CL 600 (2000-2002), the limited production (about 200 per year worldwide), 5.5 litre V12 Bi-Turbo CL600 (2003-2006), the very rare limited-edition NA CL63 AMG (26 examples only), the 2000 NA CL55 AMG F1 Edition (55 examples only), and the limited production (196 total) 6.0 litre V12 Bi-Turbo CL65 AMG (2004-2006). All models seat four. Development took place from 1993 to 1999, with final design being approved in 1996.
