<\/a><\/p>\n A few months after the launch of the new Mercedes S-Class it is AMG’s turn to show their first take on the Mercedes flagship with the 2014 Mercedes S63 AMG. We went to Austria to see what it is like to drive and fire some questions at the AMG engineers! <\/p>\n In a nutshell the 2014 Mercedes S63 AMG is the most powerful S-Class you can buy today with AMG’s own 5.5 liter V8 Biturbo engine. It sets new benchmarks for performance in this segment with a 0-100 km\/h time of just 4.0 seconds. Extensive weight saving over the previous model dropped the kerb weight below 2,000 kilogram. <\/p>\n <\/a> The Engine<\/strong><\/p>\n <\/a><\/p>\n The AMG 5.5-litre V8 biturbo engine procudes an output of 585 hp and a torque of 900 Nm. The fuel consumption of the new Mercedes S63 AMG is up to Like all AMG V8 and V12 engines, the eight-cylinder biturbo engine for the 2014 Mercedes S63 AMG is assembled by hand in the hand-finishing section at AMG. Highly qualified engine fitters assemble the M157 in Affalterbach according to the “one man, one engine” philosophy. The AMG engine plate bears the engine technician’s signature as an attest to the peerless DNA of Mercedes-Benz’s high-performance brand.<\/p>\n Performance<\/strong><\/p>\n <\/a><\/p>\n Systematic implementation of the AMG Lightweight Performance strategy reduces the weight of the S 63 AMG by up to 100 kilograms compared to the predecessor model. This weight saving was achieved largely thanks to the use of a lightweight lithium-ion battery, AMG forged light-alloy wheels, and a weight-optimised AMG high-performance composite braking 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 reduces the weight by a further four kilograms. <\/p>\n The weight saving paired with the powerful 5.5 liter V8 engine that delivers 585hp and 900Nm of torque lifts the performance figures for this \u00fcber-Mercedes to new heights. 0-100 km\/h is done in 4.0 seconds, the top speed is limited to 250 km\/h but if this restriction was not there it would be capable of breaching the 300 km\/h mark with ease. The Mercedes S63 AMG also has a very impressive power-to-weight ratio of 3.37 kg\/hp. <\/p>\n Gearbox & Drivetrain<\/strong><\/p>\n <\/a> The 2014 Mercedes S63 AMG comes with the AMG Speedshift MCT 7-speed sports transmission. The three transmission modes; Controlled Efficiency, Sport and Manual, provide the driver with a personal transmission setup. In comfort-oriented “C” mode the gearbox shifts up early to achieve better fuel economy and guarantee a fluent ride. In the “S” and “M” transmission modes the engine and transmission are significantly more agile and the ECO start\/stop function is deactivated. A brief and precisely defined retardation of ignition and injection under open throttle results in even faster and acoustically more emotional gearshifts. <\/p>\n All long-wheel base S63 AMGs come with AWD as standard, on RWD S63 AMGs the 4Matic system is an optional extra. The performance-oriented AMG 4matic all-wheel drive distributes the engine torque to send 33 percent to the front axle and 67 percent to the rear axle. The rear-biased power distribution provides the signature AMG high driving dynamics and superlative driving enjoyment as well as boosting acceleration from a standing start. The all-wheel drive also enhances driving safety on wet or wintry road surfaces. Optimum traction is guaranteed by a multi-disc clutch with a locking effect of 50 newton metres, which exploits the frictional connection potential of all four wheels to the full on snow and ice in particular. <\/p>\n <\/a><\/p>\n The technical basis for the AMG 4MATIC all-wheel drive system is a transfer case for the additional power take-off to the driven front axle. This requires no additional installation space, as it is integrated compactly into the AMG Speedshift MCT 7-speed sports transmission. The torque is transmitted from the power take-off via a propeller shaft to the front axle. Power transmission from the front axle differential to the front-left drive shaft is effected via an intermediate shaft which passes through an encapsulated shaft duct in the engine oil pan. The compact and weight-optimized design results in a comparatively low level of additional weight for the all-wheel drive system of only 70 kilograms, which also helps to reduce fuel consumption and exhaust emissions.<\/p>\n All variants of the S 63 AMG are fitted with ESP\u00ae Curve Dynamic Assist as standard. Targeted braking intervention at the inside rear wheel results in defined cornering of the vehicle and ensures greater agility when taking corners at high speed. This equivalent of torque vectoring takes away (most) understeer when turning into corners. <\/p>\n <\/a><\/p>\n Mercedes recently launched a new 9-speed gearbox for the Mercedes S-Class. We were hoping this new 9-Speed or another double-clutch gearbox would make its way into the S63 AMG at some point. But AMG engineers told us that it is currently unlikely. The new Mercedes 9-Speed gearbox is not capable of handling the insane torque of the AMG engine and the development of a completely new AMG gearbox is to expensive to happen in the short term. A shame as the gearbox is one of very few points for improvement we found in our time with the S63 AMG. <\/p>\n Suspension<\/strong><\/p>\n <\/a><\/p>\n The suspension options put is for a bit of a dilemma, in our favorite specification (long-wheel base with 4Matic) the excellent Magic Body Control suspension system is not availalbe due to space restrictions with the 4Matic. So if you want to have the extremely smooth ride that we experienced on the 2014 Mercedes S500<\/a> in combination with the AMG power you can only chose the S63 AMG in short with rear-wheel drive. The LWB S63 AMG comes with the AMG Sports Suspension and Airmatic air suspension. Not a bad setup at all but not as out-of-this-world as the Magic Body Control. <\/p>\n 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 \u2013 including higher camber, a larger anti-roll bar and a stiffer subframe carrier on the rear axle \u2013 have been developed exclusively for the S 63 AMG 4MATIC. These measures optimize the vehicle’s agility when driving dynamically.<\/p>\n

\n0.4 litres per 100 kilometres lower than that of the preceding model, even though the engine output has been increased by 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. As already mentioned this is AMG’s own engine and not a turbocharged bored out version of the V8 found in the Mercedes S500.<\/p>\n
