The CL is a luxurious coupe based on the S-Class sedan. Under the long hood, four twin-turbo engines are offered: two V8s (4.6 l / 429 hp, 5.5 l AMG / 563 hp) and two V12s (5.5 l / 510 hp, 6.0 l AMG / 621 hp). The automatic transmissions feature 7 speeds with the eights, 5 with the twelves. To tackle winter in first class, the CL550 comes with the 4Matic all-wheel-drive system as standard.
