S 65 AMG (W 221)

The exclusive crowning glory for enthusiasts

Luxury, power and sound, all in perfect harmony – this is what the Mercedes-Benz S 65 AMG is all about. The unique twelve-cylinder Saloon from AMG has a small but loyal community of fans. Since its launch in 2003, the S 65 AMG has been seen as the epitome of exclusive and effortless superiority. The same can also be said of the latest model year variant, which features a number of subtle visual enhancements, an increase in power output to 463 kW (630 hp), as well as a reduction in fuel consumption and emissions. 

Among engine specialists and car enthusiasts, a twelve-cylinder engine has always represented the crowning glory of the engine builders’ craft. A very special example of this luxurious engine series is the AMG 6.0-litre V12 biturbo engine, as used in the S 65 AMG. Just one glimpse of the engine specifications is enough to reveal why: with a displacement of 5980 cubic centimetres, the  AMG V12 generates 463 kW (630 hp) at engine speed of 4800 rpm. The maximum torque of 1000 Nm (738 lb-ft) has been electronically limited – from a possible 1200 Nm (885 lb-ft) – to make allowances for the powertrain, and remains constant between 2300 and 4300 rpm.

The performance of the vehicle is evidence of the exceptional power of the AMG twelve-cylinder engine: the S 65 AMG accelerates from 0 to 100 km/h (62 mph) in just 4.4 seconds, and is capable if hitting a top speed of 250 km/h (155 mph) (electronically limited).AMG has made a number of additional detailed enhancements to the engine, which has been in production for the past seven years. The engine experts at AMG achieved the increase in output from the previous 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 (28 hp). The maximum charge-air pressure is 1.5 bars.

Despite the increase in output, it has still be possible to reduce fuel consumption and exhaust emissions: the NEDC (New European Driving Cycle) combined fuel consumption of the S 65 AMG is now 14.3 l/100 km (16.44 mpg/US, 6.99 km/l), which equates to a reduction of 0.2 l/100 km. The CO2 emissions of 334 grams per kilometre are 3.5 percent lower than those of the previous model (346 g/km).The reduction in consumption is down to new engine electronics as well as 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.Mercedes-Benz S 65 AMG (W 221), 2009

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.

Unique driving experience, exceptional in-gear acceleration

The unrivalled effortless superiority of the AMG twelve cylinder engine can be enjoyed by drivers of the S 65 AMG in all driving situations: the tremendous acceleration characteristics are another one of its strengths, along with relaxed cruising at low engine speeds. Manual drive mode “M” in particular enables the high level of available torque and the exceptional in-gear acceleration to be enjoyed to the full. The exciting engine 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

Characteristic features of the AMG 6.0-litre V12 biturbo engine include the vast know-how amassed by AMG from the world of motor sport and applied to the engine’s construction, and also 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 – just as with the V12 engine. In line with the exceptional 1000 Nm (738 lb-ft) torque, the S 65 AMG comes with a systematically reinforced powertrain. Power transfer is handled by the AMG SPEEDSHIFT five-speed automatic transmission, which has three different drive modes.As is the case with the new S 63 AMG, the twelve-cylinder top-of-the-range model comes 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. The Direct-Steer system with speed-sensitive power steering, fitted as standard, guarantees high levels of maneuverability and smooth control in all driving situations.Mercedes-Benz S 65 AMG (W221) 2010Reliable 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.

Subtle but effective distinguishing features in the case of the V12 model

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 liner 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.Also fitted as standard 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.
