Mercedes-Benz has revealed the performance flagship in its new S-Class range, following the 'regular' model's debut earlier this year.
Entering above the V8-powered S 500, the new S 63 AMG is lighter than its predecessor, while packing in more technology than ever before.
And, while the new S 63 wears a more subtle styling kit than most of its AMG stablemates, it's the powerhouse under the bonnet - and its status as the top model - that will draw most buyers.
AMG's familiar 5.5 litre twin-turbo V8 is responsible for motivating the S 63, delivering 430kW and a hefty 900Nm of torque.
The turbo V8 is matched to AMG's Speedshift MCT seven-speed auto transmission, and it can be had with either a rear-wheel-drive or 4Matic all-wheel-drive setup.
Weighing around 100kg less than the previous model, the new S 63 rockets to 100km/h in 4.0 seconds in 4Matic form, and 4.4 seconds with the rear-wheel-drive model.
The S 63 is available in both short- and long-wheelbase form, and Mercedes claims the same performance numbers for both versions.
Fuel consumption? A mere 10.0 l/100km for the rear-wheel-drive car and 10.3 l/100km with 4Matic optioned.
Being an AMG flagship, there's also the usual assortment of sharpened suspension elements, light alloy wheels and 420mm carbon ceramic brakes - a first, although they're optional.
In the cabin, you'll find the full range of new S-Class technologies (see our 2014 S-Class Revealed article), along with AMG tweaks including a sports steering wheel and aluminium shift paddles, sports seats, AMG instruments and AMG logos emblazoned throughout.
Options include not only the carbon ceramic brakes, but also an exterior carbon fibre pack, red-painted brake calipers and a lightweight engine cover.
The S 63 AMG will make its world debut at September's Frankfurt Motor Show.
