Mercedes-Benz is all about comfort, luxury, and refinement, and the 2009 CLS-Class executes all of these exceedingly well. The CLS-Class isn't a large vehicle and the word "sedan" doesn't seem to fit this smallish car with four doors, so Mercedes-Benz calls it a four-door coupe. A computer-controlled 7-speed automatic transmission is mated to a large V8 in the CLS550, while the upper-level CLS63 will please performance enthusiasts with its very powerful 6.3L V8 engine that generates 507 horsepower. The brakes, suspension, wheels, and even steering wheel are designed by AMG. The result is a very comfortable performance car.
