Systematic implementation of the AMG Lightweight Performance strategy reduces the weight of the new 2014 Mercedes-Benz S 63 AMG by up to 100 kilograms compared to the predecessor model. This weight saving was achieved largely thanks to the use of AMG forged light-alloy wheels, a lightweight lithium-ion battery and a weight-optimised AMG high-performance composite brake system. Furthermore, the entire outer skin of the S-Class, including the roof and the front end of the body, is made of aluminium. Installing a spare wheel recess made of carbon fibre, a material used in Formula 1, reduces the weight by a further four kilograms.
The AMG 5.5-litre V8 biturbo engine with an output of 430 kW (585 hp) and torque of 900 Nm delivers effortlessly superior performance. Acceleration from 0 to 100 km/h takes 4.0 to 4.4 seconds, depending on model variant, and the top speed is 250 km/h (electronically limited). The S 63 AMG also leads the way when it comes to power-to-weight ratio, boasting a figure of 3.49 kg/hp. The fuel consumption of the new S 63 AMG is 0.4 litres per 100 kilometres lower than that of the predecessor model, even though the engine output has been increased by up to 30 kW (41 hp). The range-topping eight-cylinder model already meets the requirements of the EU6 emissions standard, which is due to come into force in 2015.
The AMG sports exhaust system in the S 63 AMG has automatic logic-controlled exhaust flaps in both rear silencers. When the transmission is in “C” (Controlled Efficiency) mode, the flaps remain closed in most situations, in which case the eight-cylinder biturbo engine’s sound is more understated – perfect for long trips and a comfortable ride in the rear. In “S” (Sport) and “M” (Manual) modes, the exhaust flaps open earlier and more spontaneously, especially if the driver prefers a dynamic driving style. The result is an even fuller, emotional, hallmark AMG engine sound.
The optionally available performance-oriented AMG 4Matic all-wheel drive distributes the engine torque so that 33 percent goes to the front axle and 67 percent is sent to the rear axle. The rear-biased power distribution provides for the signature AMG high driving dynamics and superlative driving enjoyment as well as boosting acceleration from a standing start. The all-wheel drive likewise enhances driving safety on wet or wintry road surfaces. Optimum traction is guaranteed by a multi-disc clutch with a locking effect of 50 Nm, which exploits the frictional connection potential of all four wheels to the full on snow and ice in particular.
The S 63 AMG 4Matic is fitted with AMG Ride Control sports suspension. The full air suspension system Airmatic is equipped with the Adaptive Damping System ADS Plus. One new feature is the continuous damping adjustment, which can be controlled independently in the compression stage and rebound stage. It allows better adaptation to the driving and road-surface conditions. “Comfort” and “Sport” suspension modes can be selected at the push of a button. Specific front axle kinematics – including higher camber, a larger anti-roll bar and a stiffer subframe carrier on the rear axle – have been developed exclusively for the S 63 AMG 4Matic. The S 63 AMG with rear-wheel drive features AMG sports suspension based on Magic Body Control. The new S-Class is the first car in the world able to recognise road surface undulations in advance. If Road Surface Scan detects such undulations with the help of the stereo camera, Magic Body Control adjusts the suspension in advance to suit the situation. Both suspension modes – “Comfort” and “Sport” – are also available here.
The new S 63 AMG is equipped with a weight-optimised, fade-resistant AMG high-performance composite brake system. An AMG ceramic high-performance composite brake system is available as an option for the first time. The more than 20 percent lighter design ensures lower unsprung masses as well as enhancing driving dynamics, agility and ride comfort. In addition to this, the system has a longer service life, is more resistant to corrosion and displays higher thermal stability. The AMG ceramic high-performance composite brake system has front brake discs with a diameter of 420 millimetres and is recognisable by the “AMG Carbon Ceramic” logo on the specially painted brake callipers.
