The CLS-Class made its debut in the U.S. in 2006 and it started off with a bang by offering the CLS55 AMG right off the bat. Sure, its 469-horsepower, 5.4-liter V-8 engine wasn’t nearly as stunning as the 5.5-liter used today, but it was impressive in its own right. Just a year later, the CLS63 AMG with its 507-horsepower, 6.2-liter V-8 engine gave it a spot in the market that few luxury manufacturers could match.
In the 2012 CLS63 AMG , Benz replaced the 6.2-liter engine with a 5.5-liter V-8 with a pair of turbochargers strapped to it. This smaller-displacement V-8 pumped out 518 ponies and 516 pound-feet or torque, but the AMG Performance Pack bumped that to a crazy 550 horsepower and 590 pound-feet of torque. This Performance Pack dropped the 0-to-60 mph time to a lightning-fast 3.9 seconds.
For the 2014 model year, Mercedes-Benz is expanding the CLS lineup with the addition of a more powerful AMG S-Model . Alongside the hopped up S-Model is the standard CLS 63 AMG, which is equipped with its own slew of performance-oriented features, including the AMG 4MATIC all-wheel-drive system.
This makes the CLS the fifth model in Mercedes lineup to offer the 4MATIC system as standard, along with the ML63 AMG, GL63 AMG and G63 AMG and the E-Class luxury sedan.
With the super-sexy M6 Gran Coupe making its debut in 2014 with a 560-horsepower V-8 and the 2014 Panamera coming in with a revision and a 440-horsepower twin-turbo V-8, the CLS 63 AMG 4MATIC has a lot to be worried about.
