Revealed: 2014 Mercedes-Benz S63 AMG 4MATIC

Mercedes\' 2014 S63 AMG 4MATIC has arrived.

Mercedes-Benz has unveiled its latest S63 AMG model. The S-Class' range-topping eight-cylinder model will make its first public appearance later this year at the Frankfurt Motor Show.

As with the previous car, the 2014 S63 AMG makes use of AMG's 5.5L V8 biturbo engine. However, power has increased from last year's 536 horsepower and 590 lb-ft of torque to a monstrous 577 hp and 664 lb-ft of torque.

In order to keep that added power in check, the S63 AMG now comes standard with Mercedes' 4MATIC all-wheel drive system. Similar to the 4MATIC used on the latest E63 AMG, the system send 33 percent of the engine's power to the front wheels and 67 percent to the back wheels, ensuring the S63 retains its rear-wheel frive bias.

Despite the addition of all-wheel drive - along with the new S-Class' latest luxury and safety tech - the S63 AMG 4MATIC is actually 220 pounds lighter that its predecessor, thanks to weight saving measures like a lithium-ion battery and a spare wheel recess made of carbon fiber.

Shifting through AMG's SPEEDSHIFT MCT 7-speed sports transmission, Mercedes says the S63 AMG 4MATIC can accelerate from 0-60 in just 3.9 seconds. The S63's top speed is electronically limited to 186mph.

In order to keep that kind of velocity under control, the S63 AMG 4MATIC comes standard with an AMG ADAPTIVE sports suspension. The air suspension features adaptive dampers as well as "Sport” and "Comfort” modes. For the first time, the 2014 S63 AMG 4MATIC is available with two-piece, carbon ceramic disc brakes.

The looks

The 2014 S63 AMG 4MATIC stands apart from standard S-Class models thanks to a revised front fascia that features a more aggressive lower bumper with three large air inlets. A front splitter, finished in silver shadow, helps to reduce lift.

Side sill panels run the length of the S63 AMG, giving the car a more hunkered-down look. The car is kept planted by AMG-specific wheels -- 19-inchers are standard, but buyers can upgrade to a set of 20-inch hoops.

Although a subtle cue, the S63 AMG's "V8 BITURBO" badging has been updated with "new, contemporary typography.”

Out back, the S63 AMG is recognizable by its rear diffusor - once again with silver shadow accents - and chromed tailpipes.

Inside not a whole lot has changed from the regular S-Class, but the 2014 S63 AMG 4MATIC's interior does feature AMG sports seats with electric adjustment, AMG sports steering wheel and AMG badges throughout. AMG has also recalibrated the car's TFT color display.

The 2014 S63 AMG 4MATIC is scheduled to make its world premier at September's Frankfurt Motor Show. The car will hit U.S. showrooms in November. Mercedes will announce pricing for the S63 AMG 4MATIC closer to the car's launch date.
