2006 Mercedes-Benz S 65 AMG
DaimlerChrysler Press Release)
Exclusivity and dynamism in a wholly new dimension: the new
Mercedes-Benz S 65 AMG in a nutshell. The compelling top-of-the-line
model of the brand new S-Class delivers 450 kW/612 hp and reaches
peak torque of 1000 Nm – more than any other vehicle in this
segment. The use of the new, innovative AMG high-performance
composite brakes with twin sliding callipers at the front further
illustrates the unique technological prowess of the powerful AMG
Saloon. The standard specification of the new S 65 AMG includes a
new AMG sports suspension based on Active Body Control, the
unmistakable AMG bodystyling, multi-piece 19-inch AMG light-alloy
wheels, DIRECT SELECT gearshift with AMG steering-wheel gearshift
paddles as well as the new AMG main menu with RACETIMER. The
powerful AMG Saloon stands self-confidently ahead of the
competition, testimony to the outstanding role of Mercedes-AMG GmbH
in developing extraordinary vehicles and powerful drive systems.
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. The main and big-end bearings are also made out of improved materials to compensate for peak temperatures and pressures more effectively. The charge cycle in the cylinder heads benefits from optimised combustion chambers and longer opening times of the intake valves. A modified oil pump ensures that all lubrication points are supplied with oil - even in highly demanding conditions. An engine oil cooler is integrated into the AMG front apron, with an additional engine coolant radiator located in the wheel arch.
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 increased surface area of the low-temperature radiator
provides a 25 percent reduction in intake temperature and guarantees
high power and torque output under all operating conditions and
regardless of the outside temperature, even when the engine is
operating at full load. The housings of the compressor and turbine
in both turbochargers as well as the turbine and compressor wheels
have been enlarged to cope with the maximum charge pressure of 1.5
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. The dual-circuit hydraulic braking system is controlled electronically and supports numerous driver assistance functions that improve safety and comfort. 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
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 AMG
instrument cluster with its 360-km/h dial discreetly indicates the
performance of the S 65 AMG.
