The second-generation CL (Coupé Leicht/Coupé Light or Coupé Luxusklasse/Coupé Luxury depending on who you ask…) was the C215. Built between 1999 and 2006, it was based on the W220 S-Class saloon, albeit with a shorter wheelbase for more nimble handling in line with its more sporting credentials.
The CL was available with a range of engines from the poverty-spec 5.0-litre V8 (heh, everything is relative…) through to the 6.0-litre twin-turbo V12.
Power outputs varied from 302bhp and 339lb/ft of torque to 604bhp and 738lb/ft of torque in the CL65 AMG, which is only 14bhp less power - but 259lb/ft more torque - than the McLaren F1 road car…
All were limited to a top speed of 155mph and while the fastest could reach 62mph in 4.4 seconds, even the slowest took only two seconds longer.
The CL600 you are looking at here has the 5.8-litre V12 engine that deploys 362bhp and 391lb/ft of torque, enough to reach 62mph in 6.3 seconds.
