Mercedes-Benz S63 AMG gets a new Bi-turbo engine

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.

The new S63 AMG also gets a few minor changes to differentiate it from the existing model, including "V8 Biturbo" lettering on the mudguards and the new 19-inch alloy wheels fitted with 255/40 or 275/40 R19 tires. The interior meanwhile 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.
