Under the bonnet lies a 6.0-litre twin-turbo V12 cranking out 463kW of power and 1000Nm of torque to the rear wheels via a seven-speed automatic transmission. This will see the S65 AMG Coupe hit an electronically limited top speed of 250km/h and run from 0-100km/h in 4.1 seconds.
That's faster the rear-wheel drive S63 AMG Coupe, which with its 430kW/900Nm 5.5-litre V8, can manage a 4.3sec time for the 0-100km/h standard, but it's not as brisk as the all-wheel drive S63 AMG, which can do the same run in 3.9sec.
Aiding fuel economy is automatic engine start/stop, and weight is paired back thanks to an aluminium crankcrase and the use of a lithium-ion battery in place of the more common lead acid battery. The latter move is said to shave 20 kilograms from the coupe's weight.
The S65 AMG Coupe's sports suspension setup incorporates the active curve titling function first seen in V8 S63 AMG Coupe, and which allows the car, like a motorcyclist or skier, to lean into corners. The system in the S65 has three driver selectable different modes and operates between 15km/h and 180km/h.
This is paired with Road Surface Scan, which uses a stereo camera in the windscreen to monitor the road up to 15 metres ahead of the car. In addition to keeping an eye out for curves, it can spot bumps and undulations, and adjust the Magic Body Control suspension to suit.
Chrome accents are liberally used on the S65's exterior and these are paired with 20-inch alloy wheels that have been ceramically polished. Keeping the S65 in contact with Mother Earth are 255/40 tyres up front and 285/35 tyres at the rear.
The car's optional ceramic composite brakes are claimed to 20 per cent lighter than the standard-fit stoppers.
Inside the cabin there's Nappa leather everywhere and a new three-spoke steering wheel linked to a speed-sensitive variable ratio setup. A standard head-up display projects the speedometer, as well as navigation instructions, traffic signs, speed limits and cruise control info, onto an 8.7-inch patch of windscreen ahead of the driver.
Other tech features standard on the S65 AMG Coupe include a surround view camera system, Burmester surround sound system, automated parking assistant, active cruise control that works in stop/start traffic, blind spot assistance and lane keeping assistance.
Mercedes-Benz Australia has confirmed the new S65 AMG Coupe will be sold here. It is will be available as a special order car, with the first examples set to arrive here mid-2015.
