Mercedes AMG SL 63 This ladies and gentlemen is the new SL 63 with AMG magic worked on it.  It puts out 557 PS or 530 PS of power depending on the state of tune that an owner specifies. Mercedes Benz has adopted the lighter twin turbo engine of 5.5 litre capacity in place of the 6.2 litre naturally aspirated unit that did work on the previous SL 63  AMG.  More importantly it is lighter by a whopping 125 kilograms.  The car is capable of reaching 100 km/h in 4 seconds, giving the wind in the hair idiom an entirely new meaning.
