The new SL 55 AMG: most powerful of all Mercedes-Benz passenger cars
Seville - DaimlerChrysler will be exhibiting the new SL 55 AMG, currently the most powerful of all Mercedes passenger cars. Beneath the bonnet of the exclusive top-of-the-range Roadster lies a newly developed supercharged engine with eight cylinders, developing 350 kW/476 hp. The powerplant provides its maximum torque of 700 Newton metres from just 2650 rpm a new record for V8 sports cars. The SL 55 AMG accelerates from 0 to 100 km/h in just 4.7 seconds. The impressive power development in the eight-cylinder engine is largely down to a newly developed belt-driven supercharger that generates about 30 percent more charge pressure than other comparable belt-driven supercharging systems. Rotating at over 25,000 rpm, the compressor's aluminium rotors press some 1600 kilograms of air per hour into the combustion chambers. The screw-type compressor is connected to the crankshaft by means of an electromagnetic clutch and a separate poly-V-belt, thus enabling it to spontaneously react when the driver presses the accelerator and provide powerful thrust at engine speeds barely above idling speed. Further special technical features in the V8 supercharged engine include the fuel system which, for the first time in a Mercedes-Benz, is controlled by a computer. This ensures that the right amount of fuel is delivered every time, depending on the engine speed and load. A sophisticated exhaust system with ceramic firewall catalytic converters and two powerful metal catalytic converters on the underbody reduces the high-performance sports car's emissions to a level which meets the EU-4 requirements due to come into force in 2005. High-tech systems for enhanced safety and a dynamic driving experience Like the SL 500, the new SL 55 AMG has a unique package of cutting-edge dynamic handling control systems, unrivalled by any other series-produced car in the world. It consists of the new electrohydraulic brake system, Sensotronic Brake Control (SBC), the Active Body Control system (ABC) and Electronic Stability Control, ESP®. The optimum interaction of these systems ensures that the SL 55 AMG offers a very high degree of driving safety and dynamic handling. Among the most important performance features of the new Sensotronic Brake Control system are the extremely high dynamism when building up brake pressure and the precise monitoring of driver and vehicle behaviour using sophisticated sensors. In emergency situations, SBC instantly increases the pressure in the brake lines and applies the pads to the brake discs, so that they can grip instantly with full force when the brake pedal is pressed. Furthermore, thanks to variable brake force distribution, SBC offers enhanced safety when braking through corners too. The Mercedes-AMG engineers have adapted the axles, wheels, tyres and the entire powertrain of the SL 55 AMG to the high engine output. Internally ventilated and perforated brake discs on both axles ensure safe braking. The front pad face measures 220 square centimetres, making it almost twice as large as it is in the SL 500. Gear changes at the push of a button on the steering wheel Furthermore, the high-performance sports car also comes with a 5-speed automatic transmission which sporty drivers may choose to operate using the Formula-1-style gearshift with two selector switches located behind the top two steering wheel spokes. To enable the system, the driver must first the activate "manual" mode. Further high-tech innovations which come as standard with the new SL 55 AMG include the vario-roof, which transforms the Roadster into a watertight Coupé in 16 seconds, the state-of-the-art lightweight body with its aluminium add-on parts and exemplary aerodynamics, the sensor-controlled automatic climate control system and adaptive drive dynamics which automatically adapt to the driver's personal driving style. A new type of head/thorax bag in the doors, two-stage airbags for driver and passenger, newly developed integral seats and the automatic, sensor-controlled roll-over bars make up the standard comprehensive occupant protection package on board the high-performance Roadster. Bumpers, side skirts and wheels with sporty AMG bodystyling
Visually,
features which distinguish the SL 55 AMG from the SL 500 include bumpers
with dynamic AMG bodystyling, distinctive side skirts, 18-inch multi-spoke
wheels and four chromed tailpipes. Inside the power Roadster, high-quality
aluminium trim with a sand-cast effect, AMG sports seats for perfect lateral
support and cockpit instruments with silver-coloured symbol dials and red
needles underline the exceptional character of this top-of-the-range sports
car. The integral seats are trimmed in leather featuring an exclusive AMG
perforation pattern and design. The powerful contours of the backrest side
cushions distinguish them from their counterparts in the SL 500 and mean
the seats can offer even better lateral support when cornering at speed. Mercedes-Benz SL 55 AMG
