The S-Class W221 received an AMG treatment in 2006.
It was introduced at the Paris Motor Show and sales started at the beginning of 2007.

Mercedes-Benz S-Class was one of the most known luxury cars in the world. It was a state official vehicle for more countries and its features attracted wealthy men to drive it or to be driven in it. When the S63 AMG was introduced, it was aimed directly at those who preferred to sit behind the wheel rather than behind the driver.

The dynamic look of the 2005 S-Class was enhanced with the launch of the S63 AMG and S65 AMG. The luxury barge showed its muscles on the outside with a specific look for the front bumper with a special design for the center air dam. On the sides, the smaller air scoops hosted the fog lights. On the front fenders, behind the very flared wheel arches, there was the 6.3AMG silver badge that would tell something about its performance-oriented vehicle. Through the big multi-spoke, specific AMG 19” light-alloy wheels there were huge cross-drilled brake discs. In the back, four oval exhausts were installed so the V8 engine could breathe easily.

Inside, there were some minor changes made according to the performance-oriented sedan. But it wasn’t all carbon fiber and aluminum. The owner could have configured its car with leather and wood trims. The car featured heated and ventilated seats and a massage function to rub away aches and pains on long trips.

For the S63 AMG, the car-maker installed a 6.2-liter naturally aspirated V8 engine. It was mated to a new, 7G-Tronic gearbox tuned to handle the big torque. It could propel the car to 100 kph (62 mph) in less than 5 seconds.
