The new and improved for 2011, Mercedes-Benz S63 AMG made its online debut a week after the presentation of the facelifted CL63 AMG luxury coupe. The two cars share the same AMG 5.5-litre V8 biturbo, which replaces the naturally aspirated 6.2-liter V8 unit, albeit with different output numbers.
In the 2011 S63 AMG, the hand-built 5.5-liter V8, which combines direct petrol injection with bi-turbocharging and a start/stop system, pushes out 544HP at 5,500 rpm and 800Nm /590 lb-ft of peak torque between 2,000 and 5,500rpm. If you opt for the AMG Performance package, these figures are increased to 571HP and 900 Nm / 663.8 lb-ft.
