Mercedes-Benz has updated its S63 AMG luxury performance sedan a new 5.5-litre V8 bi-turbo engine, the same unit that was offered on the recently facelifted CL63 AMG luxury performance coupe.
The new engine replaces the outgoing 6.2-litre naturally-aspirated V8 unit, and combines direct petrol injection with bi-turbocharging and a start/stop system. The hand-built engine churns out 544bhp and 800m of torque, and if specified with the AMG Performance package, is capable of producing up to 571bhp and 900Nm of torque.
Mated to AMG’s Speedshift MCT 7-speed automatic transmission, the new engine enables the S63 AMG to go from 0-100km/h in 4.5 seconds, and reach its electronically-limited top speed of 250km/h. With the AMG Performance Pack, the 0-100km/h sprint time drops to 4.4 seconds, and top speed is upped to a still-electronically-limited 300km/h.
In order to differentiate AMG from the existing model, the new S63 AMG gets a few minor changes, including “V8 Biturbo” lettering on the mudguards and the new 19-inch alloy wheels fitted with 255/40 or 275/40 R19 tires.
Meanwhile, the interior gets a revamped instrument cluster with an “AMG V8 Biturbo” starting screen, while the standard PASSION leather upholstery has been enhanced with new, contrasting colour stitching.
