The world’s most powerful series-production car: the new Mercedes-Benz S65 AMG: in a class of its own
Mercedes-Benz has issued the following press release:
The new Mercedes-Benz S 65 AMG is celebrating its world premiere at the North American International Auto Show in Detroit on January 8, 2006. Its ultra-powerful AMG 6.0-litre V12 biturbo engine delivers performance that many sports car drivers can only dream about: it accelerates from 0 to 100 km/h in 4.4 seconds and 0 to 200 km/h in just 13.3 seconds (provisional figures). The top speed is 250 km/h (electronically limited).
Twelve-cylinder biturbo engine with know-how from motorsport
This exclusive performance is made possible by the 5980-cc V12 engine developed by Mercedes-AMG. The engine’s credentials are outstanding: maximum output of 450 kW/612 hp is maintained from 4750 to 5100 rpm, while the maximum torque of 1000 Nm can be called on from 2000 to 4000 rpm. Even as low as 1000 rpm, the AMG V12 biturbo engine already delivers 570 Nm of torque to the crankshaft, while 750 Nm is on tap at 1500 rpm.
When designing and building the V12 engine the AMG designers drew on the vast know-how amassed over many years of motorsport involvement. The AMG V12 engine has a precision-balanced crankshaft made out of high-strength materials, forged pistons made out of special material which is extremely resistant to temperature and pressure, a more effective oil-spray cooling system with a separate individual nozzle for each piston plus larger piston pins.
Highly efficient charge-air cooler
The charge-air cooler has also been redesigned with a low-temperature radiator in the front of the vehicle that is around 70 percent larger. The system works on the principle of the air/water heat exchanger for particularly effective cooling of the intake air (which has been compressed by the turbochargers) before it enters the combustion chambers.
The electronically controlled fuel supply with newly developed components operates with a variable system pressure between 3.6 and 5.0 bar. Depending on the power requirements and outside temperature, the fuel pressure is variably controlled almost instantly. The engine management system translates the command from the accelerator within milliseconds, delivering an extremely fast response from the engine in all load situations.
AMG sports exhaust system for typical AMG twelve-cylinder vocals
The AMG sports exhaust system with two twin chrome tailpipes in the new V12 design provides the telltale AMG twelve-cylinder vocals on the new S 65 AMG. The new tri-metallic coating used in the catalytic converters provides a faster response from a cold start, improved emission control as well as longer life. Naturally the S 65 AMG fulfils all standard exhaust emissions limits such as EU 4. The ultra-powerful twelve-cylinder unit takes the specific requirements of the U.S. market such as LEV II, “On-Board Diagnosis II” and oxygen sensor diagnosis in its stride.
World first: newly developed AMG high-performance composite brakes
The completely newly developed AMG high-performance composite brakes based on the ADAPTIVE BRAKE system set new standards in terms of stopping distances, sensitivity and durability. A new twin sliding calliper is used for the front brakes, the kind of innovation people have come to expect from AMG. This new, unique technology combines the advantages of a floating-calliper brake – lower heat transfer to the brake fluid and significantly improved ride comfort due to the way the brake pads are located – with the performance of a large fixed-calliper brake. At the rear a large sliding frame-type calliper provides the braking. Composite brake discs at the front and rear with a diameter of 390 and 365 millimetres respectively ensure the shortest stopping distances, remarkable strength and outstanding sensitivity.
Multi-piece 19-inch AMG light-alloy wheels with mixed tyres provide the contact with the road. 255/40 ZR 19 tyres are fitted on 8.5-inch-wide wheels at the front, while 275/40 ZR 19 tyres combine with 9.5-inch-wide wheels at the rear.
AMG SPEEDSHIFT 5-speed automatic transmission with steering-wheel gearshift paddles
The drive power is transferred to the wheels in the new S 65 AMG via the AMG SPEEDSHIFT five-speed automatic transmission with AMG steering-wheel gearshift paddles and DIRECT SELECT gearshift. The conventional automatic selector lever in the centre console is replaced by a lever on the steering column, which the driver nudges to select the transmission settings “P”, “N”, “R” and “D”.
High torque requires a reinforced powertrain
The unrivalled 1000 Nm torque requires a systematically reinforced powertrain on the S 65 AMG. In the automatic transmission this includes newly developed clutch plates with a high-quality metallic coating and the modified shift and torque converter logic. Redesigned drive shafts, larger hub carriers as well as strengthened steel spring links supplement these measures.
AMG sports suspension based on Active Body Control
The AMG sports suspension with the Active Body Control system is the perfect complement to the sophisticated drive technology. The active suspension reduces almost all of the body movements that occur when moving off, negotiating bends and braking. Bends are negotiated with far less roll; the body roll with fast evasive manoeuvring is effectively suppressed. Compared with the previous model, the second-generation Active Body Control is even more effective, for instance in reducing body movements in any given driving situation. Thus the S 65 AMG opens up new dimensions in dynamic handling – while offering appreciably improved ride comfort.
Unmistakable AMG bodystyling creates a distinctive look
Hallmark Mercedes elegance coupled with distinctive sportiness – the first impression you get from the new S 65 AMG. The new AMG bodystyling is combined superbly with the pronounced flared wheel arches, providing a markedly poised and assured appearance. At the front the redesigned AMG front apron with enlarged air intakes adds an athletic touch. The two slanted struts and integrated round fog lamps set in chrome rings make the S-Class look even wider and lower. The side skirts take up the line of the AMG front apron and emphasise the dynamic feel of the side view; all reinforced through the “V12 biturbo” lettering on the front wings.
Exclusive interior appointments with multicontour seats and “RACETIMER”
The exclusive interior appointments fit in perfectly with the dynamic exterior: open the door and the S 65 AMG welcomes the driver with a large AMG logo in the AMG instrument cluster’s central display. The integrated custom AMG main menu constantly displays the gear currently selected as well as recommending when to shift up to the next gear. There is also a choice of engine oil temperature, the battery voltage or the “RACETIMER”. This new function enables the driver for the first time to calculate lap times in the AMG model – on a private racetrack, for instance. The RACETIMER stores the time of the fastest lap, the average and top speed as well as the lap distance; all the information can be called up conveniently using the thumb-operated buttons on the AMG ergonomic sports steering wheel.
The extensive burr walnut trim, the “Exclusive PASSION” leather upholstery and the AMG dynamic sports seats with their own distinctive design add that touch of distinctive flair. The AMG ergonomic sports steering wheel with its specially sculpted rim and the AMG aluminium gearshift paddles with “up” and “down” lettering is a joy to hold and behold. One of the most eye-catching features in the interior of the new S 65 AMG is the exclusive analogue clock with its “IWC Ingenieur” design in the centre console.
