Mercedes-Benz SLR McLaren
Because the charger delivers its output in fractions of a second, even the most perceptive driver will not notice the When this occurs, the electronics of the engine management system trigger an electromagnetic coupling which immediately activates the compressor, which is powered by a separate poly-V-belt. Nevertheless, the system ensures that the maximum output is available as soon as the driver calls it up by stepping on the accelerator. This means that the charger is only active when it is needed.
In order to ensure the greatest possible efficiency, the AMG engineers created an intelligent engine management system which regulates the operation of the screw-type compressor according to the engine speed and load. This means that they compress around 1850 kilograms of air into the eight combustion chambers per hour - which is up to 30 percent more than the figure achieved by rival charging systems. Despite the space-saving design, its innovative technology allows a significantly higher charge pressure than conventional mechanical chargers because the two rotors achieve a top speed of around 23,000 revs per minute, forcing air into the air inlet of the 5.5-litre powerplant at a maximum pressure of 0.9 bar. The charger is so compact that the engine specialists were able to install it between the two cylinder banks of the V8 powerplant.
To ensure good cylinder charging, the engine has a mechanical compressor with two screw-type aluminium rotors which, in the interests of low friction losses, are Teflon-coated. Power from screw-type compressor. This means that each powerplant is the responsibility of one AMG engineer, who carries out the entire engine assembly process - from installing the crankshaft in the engine block and assembling the camshafts and the compressor to cabling. In order to achieve the highest quality, the principle of 'one man, one engine' is applied. Following the usual practice at Mercedes-AMG, each SLR engine is manufactured by hand.
An important side effect of this technology is that, because of the dry sump lubrication, usually only used in motor racing vehicles, the engine is less tall and can therefore be installed at a lower level, allowing a low centre of gravity which benefits dynamic handling. The design of the powerplant's oil cooling system is also based on experience gathered in the world of motor racing: a sophisticated dry sump lubrication system with an oil capacity of around eleven litres, combined with a five-stage oil suction pump and a two-stage oil pressure pump, ensures reliable lubrication under all on-road conditions. The maximum of 780 Newtonmetres is available from 3250 rpm and remains constant in a broad engine speed range up to 5000 rpm As the figures indicate, the new SLR is endowed with what is currently one of the most powerful engines to be found in a series-produced roadgoing sports car. The result is impressive: from a mere 1500 rpm, the SLR powerplant delivers torque of over 600 Newtonmetres, rising to 700 Newtonmetres at 2000 rpm.
After an extensive concept phase, they decided in favour of an 8-cylinder design with a 5.5-litre displacement, a cylinder angle of 90 degrees, a screw-type compressor and a crankshaft supported by five bearings. When developing the powerplant, the AMG engineers applied both the expertise they had acquired during their three-decade involvement in motorsport and the stringent standards of the Mercedes-Benz brand. Engine and Transmission. Water-type charge-air cooling, three valves per cylinder, dry sump lubrication and four metal catalytic converters are further special features of this powerful engine - an engine which already meets stringent EU 4 exhaust gas regulations which are not due to come into force until 2005.
The V8 powerplant is mounted on a robust aluminium frame and has a low installation position. In the interests of optimum weight distribution, optimum dynamic handling and high stability on braking, the Mercedes-Benz SLR McLaren has a front mid-engined design. The two-seater has a top speed of 207 mph (334 km/h). With this kind of power under the bonnet, the Mercedes-Benz SLR McLaren delivers performance figures which are among the best in its class: this high-performance sports car takes just 3.8 seconds to sprint from 0 to 100 km/h, it passes the 200 km/h mark after 10.6 seconds, and from a standing start it takes just 28.8 seconds to reach 300 km/h.
With its 5.5-litre displacement and screw-type compressor, the engine develops a peak output of 460 kW/626 hp and delivers its maximum torque of 780 Newtonmetres from 3250 rpm - a figure which remains constant across a broad engine speed range of up to 5000 rpm. For evidence, simply take a glance under the bonnet at the Mercedes-AMG V8 powerplant. Just like its legendary predecessor of 1955, this SLR incorporates new technological developments which are ahead of their time. These attributes come together to form the basis for an automobile with a very special charisma - an impressive synthesis of Mercedes tradition and innovation in every respect.
This combination of knowledge and expertise is evident not only in the host of pioneering developments, impressive performance figures and superior driving characteristics of the SLR, but also in the extremely high levels of safety and practicality which it offers. The new super sports car allows Mercedes-Benz and its Formula 1 partner McLaren to showcase their collective experience in the development, construction and production of high-performance sports cars. A contemporary interpretation of stylistic elements lifted from the original SLR and design details taken from the 2003 Formula 1 Silver Arrows allow the 21st-century SLR to form a bridge between the past and the future, bringing cutting-edge motorsport technology to the road, just as the inspirational SLR Coupe did in 1955. It is a passion which can be traced way back through automotive history and which was demon-strated with the Uhlenhaut Coupe. The Mercedes-Benz SLR McLaren revives the glorious tradition of the SLR and marks the reawakening of Mercedes-Benz' passion for super sports cars.
