Mercedes S-Class coupé gets turbo treatment

The results will be seen for the first time when the ultra fast car makes its global debut at the New York International Auto Show in April.

For many, the S-Class coupé was already jaw-dropping to look at.  It’s a car that offers all of the creature comforts, refinery and technological innovation of a premium, premium, executive car, yet distilled into a sloping, GT form.

And now, thanks to the addition of an AMG 5.5-liter V8 biturbo engine, it is going to be equally jaw-dropping to drive. As Tobias Moers, Chairman of the Board of Management of Mercedes-AMG GmbH says: “The new S 63 AMG Coupé is another exciting AMG dream car in the luxury segment. Mercedes-AMG is putting the pedal to the metal again in the new year. Our model initiative is set to continue at blistering pace in 2014.”

And, looking at the performance specs, that is not hyperbole. This car is huge and seats four in living room levels of tranquility. Yet, with enough pressure applied to the accelerator, it will go from stately to 100 kph in as little as 3.9 seconds and on to an electronically limited top speed of 155 mph (250 km/h).

Part of this is down to the engine’s huge levels of torque and horsepower 900 Nm and 585 hp respectively, but it’s also due to the fact that AMG has managed to shed the car of 65 kg thanks to prodigious use of aluminium, composite materials in the braking system, specially forged light alloy wheels and a lithium ion battery.

This weight saving also helps to improve fuel efficiency. The car is capable of returning 27.9 mpg on the combined cycle.

And of course, being a top-of-the-range Mercedes-Benz, the S 63 AMG Coupé is packed full of technological toys and cutting-edge driving features. Not least the magic Body Control suspension system that keeps the car planted and comfortable plus a curve tilting function that makes the car literally lean into corners and bends — like a skier or motorcyclist — for better roadholding grip and a better racing line.

The S 63 AMG Coupé is scheduled to go on sale before the end of 2014.
