New engine, new transmission, new all-wheel drive, new exterior and interior design: On the S 63 4MATIC+, Mercedes-AMG has honed the driving dynamics and looks further. For improved performance with significantly reduced fuel consumption, the AMG 4.0-litre V-8 Biturbo engine with cylinder deactivation replaces the previous 5.5-litre V-8 Biturbo. Despite the smaller displacement, the new engine puts out 450 kW (612 hp) and thus exactly 20 kW (27 hp) more than the preceding model. With a sprint time of 3.5 seconds from zero to 100 km/h (62 mph), the performance luxury saloon is on par with full-blooded sports cars. The AMG SPEEDSHIFT MCT 9‑speed sports transmission supersedes the previous 7-speed transmission. This has enabled more agile response times to be achieved. The fully variable AMG Performance 4MATIC+ all-wheel-drive system provides optimal traction.
At the same time as the S 63 4MATIC+, the top-of-the-range model S 65 has been given a visual update that underscores the flagship position of the 12-cylinder model. Its 6.0-litre V-12 Biturbo engine retains its output of 463 kW (630 hp) and peak torque of 1000 Nm (738 lb-ft). Thanks to the advanced stage of development of the V8 and V12 biturbo engine, both new models are among the leading competitors in terms of output and torque.
New MULTIBEAM LED headlamps with ULTRA RANGE Highbeam and the updated front apron with jet wing underscore the more expressive appearance of both S-Class models. At the rear, the new apron and individual tailpipe trim add distinctive design focuses.
“Impressive power, torque and performance on the road and expressive design are the hallmarks of the new Mercedes-AMG S 63 4MATIC+ and the new S 65. We have also taken a major step forward with the S 63, helping to underline our leadership claim in this segment when it comes to driving dynamics, performance, traction, equipment and convincing comfort. The S 65 with its high-torque 6.0-litre V-12 Biturbo engine remains the spearhead of the S-Class models,“ says Tobias Moers, Chairman of the Managing Board of Mercedes‑AMG GmbH.

Front apron with new jet wing
The new S 63 4MATIC+ and the new S 65 can be identified from the front by the MULTIBEAM LED headlamps with ULTRA RANGE Highbeam and the redesigned front apron with expressive jet wing. The large side air intakes provide an improved airflow to the cooling modules – their functional form is familiar from motorsport. The three-dimensional front splitter reduces lift at the front axle. The exclusivity of the S 65 is further underlined by air inlet grilles in high-sheen chrome in the front apron.
The door sill panelling with three-dimensional high-gloss chrome inlays lower the S-Class visually closer to the road and create even more tension in the side. Typical features of the AMG S-Class models are the large forged light-alloy wheels with a diameter of 19 inches as standard on the S 63 4MATIC+ and of 20 inches as standard on the S 65. The exclusive forged wheels for the V12 saloon have an unusual design: each of the 16 spokes twists in a special way so that the light-catching contours radiate to the centre of the wheel hub. The effect: The wheel appears larger than its actual dimensions of 8.5 J x 20 at the front and 9.5 J x 20 at the rear. In addition, the ceramic mirror polishing ensure an exclusive look.
As standard, the forged wheels feature a high-quality, bolted and fully integrated wheel bolt cover made of forged aluminium. Its shape is reminiscent of a centre lock as seen in motorsport. The AMG logotype is incorporated into the rim as a design element. Three other forged wheels of the same size are optionally available – two design variants also painted matt black with a high-sheen rim flange.
The powerful rear end of the S 63 4MATIC+ and S 65 is formed by the updated rear apron with diffuser insert and the redesigned model-specific dual tailpipes of the AMG sport exhaust system. Additional stand-out features are the many high-gloss chrome design elements at the front, side and rear, which develop their radiant effect especially in combination with dark paint finishes.
Stringent implementation of the AMG Lightweight Performance strategy also contributes to the high driving dynamics and low fuel consumption. The lightweight construction measures include the use of a lightweight lithium-ion battery, AMG forged light-alloy wheels and the 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 are made of aluminium. A carbon-fibre spare wheel recess saves further weight.
The stylish character of the new S-Class models from Mercedes-AMG is also evident in the interior: Both models welcome their passengers with an exclusive ambience. The AMG power sports seats with memory function and seat heating offer the driver and front passenger more lateral support. Nappa leather in AMG V-8 design with AMG badges in the front and rear backrests creates a luxurious atmosphere on board.
The Performance steering wheel, in an all-new design with flattened lower edge and sides, features two broad horizontal spokes between which the control elements for cruise control, DISTRONIC, telephony, volume and the on-board computer are positioned, and two vertical struts, one on either side of the AMG logo on the steering wheel rim. There are also shift paddles and a more sharply contoured rim in black nappa leather with perforated leather in the grip area. As an option the steering wheel can also be ordered in black nappa leather/DINAMICA microfibre.
Special touches include the embossed emblem on the armrest of the front centre console and the analogue clock in exclusive IWC design, which features three-dimensional, milled metal hands and genuine metal appliqués on the face. The S 65 is characterised by Exclusive nappa leather in the hallmark AMG diamond design as standard, and the optional designo Exclusive nappa leather interior concept in three attractive colour combinations.
Another hallmark AMG speciality are the displays: The 31.2-cm TFT wide-screen colour display reproduces round dials that provide information about engine speed, vehicle speed and lots of additional data. The driver can choose from three display designs, Classic, Sport and Progressive. In addition, the AMG menu has been expanded considerably. Among other things, it can display the engine and transmission oil temperature, lateral and longitudinal acceleration, engine output and torque, boost pressure, tyre temperatures and pressures as well as the current vehicle set-up.
Motorsport enthusiasts can record numerous vehicle data and lap times on the race track with AMG Track Pace in the S 63 4MATIC+. All values are shown on the COMAND display, and in the Widescreen Cockpit the current times can also be read off in the instrument cluster. Based on the data, drivers are able to analyse their driving style with precision and can use the insights gained to improve their lap times.
Highest output rating for the 4.0-litre engine
The AMG 4.0-litre V-8 Biturbo engine in the S 63 4MATIC+ comes exclusively in the highest performance stage to date rated at 450 kW (612 hp). The peak torque of 900 Nm (664 lb-ft) also represents a new maximum. It is available across a wide rev range between 2750 and 4500 rpm, and thereby provides a sense of superior poise. The sprint from standstill to 100 km/h (62 mph) takes just 3.5 seconds, faster than in any other performance luxury saloon, and the dynamic push in the back does not end before reaching the electronically limited top speed of 250 km/h / 155 mph (with AMG Driver’s Package: 300 km/h / 186 mph).
The further advanced AMG 4.0-litre V-8 Biturbo engine utilises well-proven twin-turbo forced induction, with the two chargers not located outside on the cylinder banks, but rather between them in the V of the cylinders. The advantages of the “hot inside V” are: a compact engine design, an immediate response from the turbochargers and low exhaust emissions thanks to optimum airflow to the close-coupled catalytic converters.
Two twin-scroll turbochargers are deployed to boost performance and further improve response times. The housing is divided into two parallel flow passages. Combined with two separate exhaust ducts in the exhaust manifold, this makes it possible to control the exhaust gases on the turbine wheel separately. The exhaust gas from the first and fourth cylinders of the cylinder bank is fed into one duct and exhaust gas from the second and third cylinders to the other duct. The aim is to prevent the individual cylinders from having mutually adverse effects on the gas cycle. This reduces the exhaust gas back pressure and improves gas exchange. The results are increased output due to improved cylinder charge with fresh mixture, more torque at low revs and very immediate response times.
Other engine measures include new pistons, an optimised air intake and charge air cooling, as well as extensive software developments. Spray-guided direct petrol injection with piezo injectors, the all-aluminium crankcase, the four-valve-per-cylinder design with camshaft adjustment, air-water charge air cooling, alternator management, the ECO start/stop function and the gliding mode have all been retained.
To sum up, the eight-cylinder engine thrills with its exceptional power delivery and powerful acceleration in all engine speed ranges combined with maximum efficiency for low consumption and emission values.
For maximum efficiency, Mercedes-AMG equipped the V-8 engine in the S 63 4MATIC+ with the AMG Cylinder Management cylinder deactivation system. In the partial-load range, cylinders two, three, five and eight are deactivated, which significantly lowers the fuel consumption. With a combined fuel consumption of 8.9 litres and combined CO2 emissions of 203 grams per kilometre, the new S 63 4MATIC+ is among the leaders in its competitive segment.
When the driver has selected the “Comfort” transmission driving mode, the cylinder deactivation system is available in the wide engine speed range from 1000 to 3250 rpm. The AMG main menu on the instrument cluster informs the driver whether the cylinder deactivation system is in use and whether the engine is presently operating in the partial or full-load range. The transition from four to eight-cylinder operation is immediate, fast and imperceptible, so that the passengers do not experience any loss of comfort whatsoever.
This is made possible by intelligent interaction between the high-performance engine management system and CAMTRONIC valve lift adjustment, which is familiar in a similar configuration from the four-cylinder engines. There are eight dual actuators involved in half-engine mode, which operate the axially sliding cam units of the intake and exhaust camshafts via a shift gate. Half-engine operation is achieved by shutting off the relevant intake and exhaust valves of cylinders two, three, five and eight. This not only enables the load-change losses of the four deactivated cylinders to be reduced, but also increases the efficiency of the four remaining cylinders. The reason for this is to shift the operating point to higher loads.
Delivering a sensational drive: the V12 biturbo engine in the S 65
The 6.0-litre V12 biturbo engine with an output of 463 kW (630 hp) and maximum torque of 1000 Nm promises superior performance: the S 65 AMG accelerates from 0 to 100 km/h in 4.3 seconds and has a top speed of 250 km/h/155 mph (electronically limited, with the AMG Driver’s Package: 300 km/h). Stylish drive comfort, tremendous pulling power and effortless power delivery in all speed ranges are coupled with refined engine running characteristics and the distinctive typical sound of the AMG V12.
Technical highlights of the AMG 6.0-litre V12 biturbo engine include the aluminium crankcase, the forged crankshaft in high-grade alloy steel, the multi-spark ignition with twelve twin-spark ignition units, the air-to-water charge air cooling with low-temperature circuit, alternator management and the ECO start/stop function.
S 63 4MATIC+ with AMG SPEEDSHIFT MCT 9-speed sports transmission
For the first time, the S 63 is fitted with the AMG SPEEDSHIFT MCT 9-speed sports transmission, which impresses with extremely short shift times, fast multiple downshifts and a double-clutching function. A wet start-off clutch replaces the torque converter of the production model. This saves weight and improves the response to the driver’s accelerator pedal input, particularly during acceleration and load changes.
S 65 with AMG SPEEDSHIFT 7G-TRONIC PLUS transmission
The extremely high torque of the S 65 is transferred by the proven AMG SPEEDSHIFT 7G-TRONIC PLUS transmission. It delivers convincing tailor-made dynamics and high variability. Whether automatic or initiated by the driver using the steering wheel paddle shifters, upshifts or downshifts are carried out quickly and directly. Especially in the “Sport+” and in manual driving modes, the transmission is very fast and responsive.
The S 63 4MATIC+ is fitted as standard with the controllable AMG Performance exhaust system to achieve an even more emotionally appealing sound experience. The infinitely adjustable flaps modulate the exhaust note authentically and directly. The flaps open or close according to the selected AMG DYNAMIC SELECT drive program, but can also be controlled individually via a separate push button switch in the AMG DRIVE UNIT in the centre console. In the “Comfort” and “Sport” modes, the low-frequency sound typical of a V-8 emphasises comfort. In “Sport+” it has a much more emotional appeal.
