Mercedes-AMG is redefining the performance saloon. The brand is turning the most intelligent executive saloon into the most powerful E-Class of all time in the shape of the next generation of the E 63 4MATIC+ and E 63 S 4MATIC+. Mercedes-AMG is also setting new benchmarks in this market segment with its innovative technologies. The intelligent drive strategy raises the limits of the performance saloon’s vehicle dynamics to a completely new level. Delivering superior acceleration, the 4.0-litre twin-turbo V8 engine generates up to 450 kW (612 hp). This makes it the most powerful engine to have ever been installed in an E-Class. At the same time it is even more efficient thanks to a cylinder deactivation system fitted as standard, and thus sets the benchmark in its segment. With acceleration of 3.4 seconds from 0 – 100 km/h the new business limousine is at the top of its class. The AMG SPEEDSHIFT MCT (Multi Clutch Technology) nine-speed sports transmission is combined with a wet start-off clutch for the first time. This enabled more agile response times to be achieved. Another highlight is the completely new AMG Performance 4MATIC+ all-wheel drive system. It combines the advantages of various drive configurations. Torque distribution on the front and rear axles, which until now was strongly rear-biased, is fully variable for the first time. This ensures optimum traction right up to the physical limit, whatever the road conditions. The expressive exterior design, featuring a new radiator grille and coupé-style inset bonnet, underlines the performance figures. The next generation of the E 63 thus offers a completely new level of sportiness and comfort on long journeys.
The latest generation of the E 63 4MATIC+ and the E 63 S 4MATIC+ sees Mercedes-AMG introducing a number of new developments that redefine the performance saloon. Innovative powertrain engineering and maximum performance are combined with distinctive design, exclusive equipment and the latest infotainment features for comprehensive, connected multimedia applications.
“The new E 63 models represent the biggest step forward we’ve ever taken from one generation to the next. Vehicle dynamics were especially important to us. At the start of the development process, we opted for a fully variable all-wheel drive system which, when combined with the advanced performance of the 4.0-litre twin-turbo V8 engine, reaffirms our brand’s “Driving Performance” claim,” explains Tobias Moers, Chairman of the Board of Management of Mercedes-AMG GmbH.

Every detail of the exterior and interior is designed to enable AMG Driving Performance to be experienced at first hand. The expressive exterior design is all about sinuous edges and defined muscles. With a completely distinctive design forward of the A-pillar, the sporty front also demonstrates the effort that Mercedes‑AMG has put into the styling: For the first time on an AMG saloon, the bonnet is inset between the wings and bumper like on a coupé, thus exhibiting an entirely new, more dynamic approach to the sculpting. More powerful-looking and 17 mm wider, the wheel arches accommodate the greater track width and the larger wheels on the front axle.
The new radiator grille with twin louvres in silver chrome, vertical black struts and “AMG” lettering likewise emphasises the distinctive look. A wide front apron inspired by the design of a jet wing, with flics in black and a large front splitter, impressively epitomises the power of the new models. It also showcases the sophisticated cooling technology – a typical feature from motorsport and another visual reference to the powerful engine. The two louvres in the outer cooling-air intakes also help in this regard, their targeted wing profile directing air to the wheel arch coolers.
Overall, the front section exudes exceptional power and thus conveys the strong forwards thrust of the new performance saloon at first glance.
The side view reinforces this impression by way of numerous, carefully matched elements. One special detail is the arrow-shaped wing signet in silver chrome bearing three-dimensional “V8 BITURBO 4MATIC+” lettering – an eye-catching way to highlight the drive system. The side sill panels make the saloon appear to sit even lower on the road and elongate the overall line. Inserts in silver chrome differentiate the S-Model.
As standard, the E 63 4MATIC+ comes with 9.5 J x 19 (front) and 10 J x 19 (rear) 10-spoke light-alloy wheels painted titanium grey with a high-sheen finish, with tyres in size 265/35 ZR 19 (front) and 295/30 ZR 19 (rear). The E 63 S 4MATIC+ runs on tyres of sizes 265/35 ZR 20 (front) and 295/30 ZR 20 (rear) mounted on 9.5 J x 20 (front) and 10 J x 20 (rear) 5-twin-spoke light-alloy wheels, painted matt titanium grey with a high-sheen finish. A new design of 20-inch cross-spoke forged wheel, which looks as though it is centrally locked, is available as an option.
The muscular rear end provides the finishing touch in conjunction with the clearly defined spoiler lip in the colour of the vehicle on the boot lid, the rear apron with diffuser-look insert, and the two bright chrome-plated twin tailpipe trim elements on the selectable sports exhaust system. The E 63 S 4MATIC+ also features a trim strip in silver chrome on the rear apron.
Designers and aerodynamics experts worked together to develop the E 63 4MATIC+. Their insights not only resulted in the striking AMG bodystyling but also the performance-oriented lift balance – for agile handling characteristics on country roads and optimum driving stability at high speeds on the motorway. The developers also placed great importance on achieving a low level of wind noise, minimal aerodynamic drag for low fuel consumption, and thermal robustness for all systems. The complete package of measures involves a number of details on the front and underbody. Adapted to the saloon’s airflow and topography, the clearly defined rear spoiler eliminates lift on the rear axle.
The versatile AMG 4.0-litre twin-turbo V8 engine in the E 63 S 4MATIC+ takes peak performance to a new level at 450 kW (612 hp). Maximum torque attains a new best value of 850 Nm (627 lb-ft). It is available over a broad engine speed range of 2500 to 4500 rpm and so provides a feeling of effortless superiority in every accelerator pedal position. A sprint from zero to 100 km/h (62 mph) is absolved in 3.4 seconds, and this dynamic acceleration only ends at the governed top speed of 250 km/h/155 mph (with AMG Driver’s package: 300 km/h/186 mph). The E 63 4MATIC+ is rated at 420 kW (571 hp) and has 750 Nm (553 lb-ft) of torque. This variant accelerates to 100 km/h (62 mph) in 3.5 seconds.
The advanced AMG 4.0-litre V8 biturbo engine utilises well-proven twin turbocharging, 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 inner V” are a compact engine design, an immediate response from the twin-scroll turbochargers and low exhaust gas emissions thanks to optimum air flow for the close-coupled catalytic converters.
Two twin-scroll turbochargers are deployed for the first time to boost performance and improve responsiveness further. 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.
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 has equipped the V8 engine with the AMG Cylinder Management cylinder deactivation system. This already helped the SLK 55 to achieve impressively low consumption and emission values and is now being used with a turbocharged engine from the high-performance sports car brand for the first time. In the partial-load range cylinders two, three, five and eight are deactivated, which crucially lowers the fuel consumption.
When the driver has selected the “Comfort” transmission drive program, 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.
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.
Both E 63 models are exclusively available with the innovative AMG Performance 4MATIC+ all-wheel drive system. This newly engineered, intelligent system brings together the advantages of various drive configurations. Torque distribution on the front and rear axles, which is fully variable for the first time, ensures optimum traction right up to the physical limit. The driver is also able to rely on high driving stability and handling safety under all conditions, whether the roadway be dry, wet or snow-covered. The transition from rear-wheel to all-wheel drive and back again is seamless, because intelligent control is integrated into the vehicle system architecture as a whole.
An electromechanically controlled coupling connects the permanently driven rear axle variably to the front axle. The best possible torque distribution is calculated continuously according to the driving conditions and driver’s input. The performance saloon can thus be driven in a continuously variable way from traction-oriented all-wheel drive to purely rear-wheel drive. Transitions are seamless and based on an elaborate matrix. In addition to traction and lateral dynamics, the all-wheel drive system also improves the longitudinal dynamics for even more powerful acceleration.
It is still possible to drift thanks to fully variable torque distribution. This is where drift mode, part of the standard specification for the E 63 S 4 MATIC+, comes into its own. This can be activated in the “Race” drive program using the shift paddles, provided that ESP® is deactivated and the transmission is in manual mode. When drift mode is activated, the E 63 S 4MATIC+ becomes a purely rear-wheel drive vehicle. Drift mode remains engaged until the driver deactivates it again.
