The Mercedes SLR Mclaren is nothing short of spectacular
The Mercedes SLR McLaren was inspired by the Mercedes-Benz 300 SLR of 1955, based on the W196 F1 car, yet named after the road-going 300SL Gullwing. It was introduced on 17 Nov 2003. The Mercedes-Benz SLR McLaren is developed by Mercedes-Benz and McLaren Automotive, built in Portsmouth and the McLaren Technology Centre in Woking, Surrey, England and sold from 2003 to 2009.With some exotic looks and and a power plant to match its price this is a car to behold.
With the combination of knowledge and expertise from Mercedes-Benz and its Formula 1 partner McLaren , the SLR has a very special charisma which is very 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 and this makes it a very expensive sports car. The car's base price, US$450,000 made it the ninth most expensive street-legal car in the year 2008. so lets look at the features that make this car pricey.
The SLR sports a 232 kg (510 lb) hand-built 5,439 cc (5.439 L; 331.9 cu in), supercharged, all-aluminium, SOHC V8 engine. The cylinders are angled at 90 degrees with three valves per cylinder and lubricated via a dry sump system. The compression ratio is 8.8:1 and the bore and stroke is 97 millimetre (3.82 in) and 92 millimeters (3.62 in), respectively. The Lysholm-type twin-screw supercharger rotates at 23000 revolutions per minute and produces 0.9 bar (13 psi) of boost. The compressed air is then cooled via two intercoolers. The engine generates a maximum power of 626 PS (460 kW; 617 hp)@6500rpm and maximum torque of 780 N·m (580 lb·ft)@3250-5000rpm.
The Mercedes SLR Mclaren features active aerodynamics; there is a spoiler mounted on the rear integral air brake flap. The spoiler increases downforce depending on its angle of elevation (angle of attack). At speeds above 95 km/h (59 mph) the spoiler/brake automatically raises to 10 degrees (15 in 722 edition), when demanded via the driver's switch, the elevation can be increased to 30 degrees (35 in 722 version) for increased rear downforce, at the cost of increased steady state drag, also when the driver applies the brakes the spoiler raises.
The Mercedes SLR Mclaren uses AMG SPEEDSHIFT R 5-speed automatic transmission with 3 manual modes. For durability Mercedes selected a 5-speed transmission rather than their 7-speed gearbox which was more complex and used more parts.
The Mercedes SLR Mclaren features Sensotronic, a type of brake-by-wire system. The brake discs are carbon-ceramic and provide better stopping power and fade resistance than steel discs when operating under ideal working temperature. Mercedes-Benz claims these discs are fade resistant to 1,200 °C (2,200 °F). The front discs are internally vented and 370 mm (15 in) in diameter. 8 piston calipers are used. Rear discs are 360 mm (14 in) in diameter with 4 piston calipers. During wet conditions the calipers automatically skim the surface of the discs to keep them dry.
The car uses carbon fiber for its entire body construction in an attempt to keep the weight low. The total curb weight is 1,750 kg.
Aluminium was the key material for the developers of the new Mercedes-Benz SLR McLaren's suspension. It has a double wishbone suspension at the front and rear. The wishbones are made from forged aluminium, while the wheel mounts are cast in aluminium. Springing/damping combinations at the front and rear axle and an anti-roll bar at the front complete the suspension structure.
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. The two-seater has a top speed of 207 mph (334 km/h).
Interior Design and Special Features
It has some race-bred carbon fiber seats. One can also get the seats customized to the taste of every vehicle's owner. The interior design is German and accented with leather, carbon fiber and aluminum. The engine start button hides beneath a flip-up cover on the gear lever.
Those who want a sleek, modern supercar with stunning good looks and plenty of power to burn get the Mercedes SLR Mclaren. Contrary to what its price, carbon-fiber construction and 626bhp output might suggest, the SLR is a true road racer.
