2011 Mercedes-Benz S63 & S65 AMG

(from Daimler press release)  AMG has made a number of additional detailed enhancements to the AMG 6.0-litre V12 biturbo engine for the new model year. The engine experts at AMG achieved the increase in output from 450 kW (612 hp) to 463 kW (630 hp) thanks to new exhaust gas turbochargers. The inlet diameter of the compressor housing and also the exhaust gas ducts have been enlarged, and the resulting increase in air throughput, together with the new engine electronics, has resulted in an increase of 13 kW (18 hp). The maximum charge-air pressure is 1.5 bars.

Despite the increase in output, it has still been possible to reduce fuel consumption and exhaust emissions: the NEDC-combined fuel consumption of both models is now 14.3 litres per 100 kilometres, which equates to a reduction of 0.2 litre per 100 km. CO2 emissions are 334 grams per kilometre (previous model 346 g/km).

The reduction in fuel consumption is achieved thanks to the new engine electronics and generator management: the kinetic energy generated during each drive phase of the engine and also when braking is used to charge the battery, and not just left to generate heat as would otherwise be the case. In all other operating areas, management of both the on-board electrical system and generator enables the generator to be maintained at a low voltage level.

New piston rings, a modified oil pump and use of a superior coating on the catalytic converters also contribute towards reducing raw exhaust emissions as part of the package of measures. As a result, the S 65 AMG and CL 65 AMG immediately fulfil the current EU5 emissions standard as well as all of the requirements of the US market (LEV II standard, on-board diagnostics II and lambda sensor diagnostics).

Since its debut in 2003, the AMG 6.0-litre V12 biturbo engine has ranked as one of the most powerful series production engines ever built. The exciting sound emitted by the two chrome twin tailpipes of the AMG sports exhaust system changes according to the driving style and situation: the repertoire ranges from a smooth, refined tone, through to the sonorous AMG-typical twelve-cylinder sound, all of which adds to the intensity of what is a high-performance driving experience.

Know-how from the world of motorsport also with the AMG biturbo V12 engine

One of the characteristic features of the biturbo engine is the sophisticated air/water intercooler. It guarantees high power and torque output under all operating conditions, regardless of the outside temperature. Traditionally all engines are built by hand at Mercedes-AMG in Affalterbach according to the philosophy "one man, one engine" – this is also true of the V12 engine.

In line with the exceptional 1000 Nm of torque, the saloon and coupé come with a reinforced powertrain. Power transfer is handled by the AMG SPEEDSHIFT five-speed automatic transmission, which has three different drive modes.

Torque Vectoring Brake, crosswind stabilisation and the Direct-Steer system

As is the case with the V8 models, the twelve-cylinder variants also come with the AMG sports suspension based on Active Body Control (ABC) with Torque Vectoring Brake, crosswind stabilisation and loading adjustment system. The characteristics of the AMG sports suspension can be changed by pressing the Sports button – for the driver, this translates into a noticeable reduction in the roll angle when cornering at speed, and also stiffer spring/damper tuning. High levels of maneuverability and smooth control in all driving situations are also guaranteed by the Direct-Steer system with speed-sensitive power steering, which is fitted as standard.

A further increase in active and passive safety

Reliable deceleration performance comes courtesy of the AMG high-performance braking system based on the ADAPTIVE BRAKE system. Internally ventilated, perforated composite brake discs all round, with a diameter of 390 and 365 millimetres respectively, are combined with double floating brake callipers (front) and sliding frame-type callipers (rear) for maximum deceleration.
To enhance active and passive safety, the range of trend-setting camera and radar-based driver assistance systems has also been extended further. As with the V8 models, new optional extras for the S 65 AMG and CL 65 AMG now therefore include Active Lane Keeping Assist and Active Blind Spot Assist.

Subtle but effective distinguishing features for the S 65 AMG

The S 65 AMG comes with AMG twin-spoke forged wheels, painted in titanium grey with a mirror finish, measuring 8.5 and 9.5 inches wide. 255/35 R 20 tyres are fitted at the front, while 275/35 R 20 tyres feature at the rear. When it comes to appearance, the V12 model differs from the S 63 AMG in terms of the exclusive radiator grille with twin chromed louvres, the LED Light package including Intelligent Light System, and also the "V12 BITURBO" lettering on the front mudguards.

In the interior, the AMG instrument panel features the "AMG V12 BITURBO" start screen as well as exquisite Exclusive PASSION leather upholstery: the entire instrument panel and door linings, and also the seatback panels are finished in leather, as are the magazine pockets and the parcel shelf. Alcantara® is also used on the roof lining and on the A, B and C-pillars. Another new touch is the contrasting colour stitching.

The 12-way electrically adjustable AMG sports seats come with the Memory package, distinctive seat fluting and leather upholstery in the AMG V12 diamond pattern design, which also extends over the rear seats and all four door centre panels. Also fitted as standard is the Seat Comfort package, which includes front active multicontour seats with massage and dynamic handling function and NECK-PRO luxury head restraints and rear multicontour seats with massage function. All seats feature active ventilation and heating as well as the PRE-SAFE® positioning function.

Bang & Olufsen BeoSound AMG high-end sound system as standard

Also fitted as standard on the S 65 AMG is the Bang & Olufsen BeoSound AMG high-end sound system, including SPLITVIEW and Front Entertainment package. Newly developed especially for the S-Class by AMG together with renowned Danish hi-fi specialists Bang & Olufsen, the system promises a unique listening experience. With a total output of 1200 watts, 15 loudspeakers, acoustic lens tweeters in the A and B-pillars as well as a digital sound processor (DSP), it transforms the V12 saloon into a full-blown concert hall with perfect acoustics.

S 63 AMG

Exciting cutting-edge technology from Affalterbach: the Mercedes-Benz S 63 AMG and the CL 63 AMG are to benefit from a completely newly developed powertrain. The AMG 5.5-litre V8 biturbo engine with a peak output of up to 420 kW (571 hp) and a torque of up to 900 Nm, in combination with the unique AMG SPEEDSHIFT MCT 7-speed sports transmission, contributes towards a considerable reduction in consumption and emissions, while at the same time increasing maximum power and torque. With a fuel consumption of 10.5 litres per 100 kilometres (NEDC combined), the new high-performance cars not only undercut their direct competitors – they are also more than 25 percent more economical in terms of their fuel consumption than the previous models with naturally aspirated V8 engine.
