system. The brake disc
The disc brake or disk brake is a device for slowing or stopping the rotation of a wheel while it is in motion.A brake disc is usually made of cast iron, but may in some cases be made of composites such as reinforced carbon–carbon or ceramic matrix composites. This is connected to the wheel and/or...
s 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 1200 °C (2,192 °F). The front discs are internally vented and 370 mm (14.6 in) in diameter. 8 piston calipers are used. Rear discs are 360 mm (14.2 in) in diameter with 4 piston calipers. During wet conditions the calipers automatically skim the surface of the discs to keep them dry.
To improve braking performance there is an automatic air brake, when engaged the rear elevation angle of the rear spoiler is set to 65 degrees. The additional rear downforce in addition to the markedly increased aerodynamic drag increases peak deceleration ~90%.
The brakes have been strongly criticized by such review sources as Top Gear due to lacking modulation and having an on-off operation. This is due to road cars not regularly reaching normal operating temperature for ceramic discs in stop-go traffic conditions.
The SLR 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 SLR sports a 232 kg (511.5 lb) hand-built 5439 cc, 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@6500rpm and maximum torque of 780 newton metre@3250-5000rpm.
Unlike most of its contemporaries, its engine is front-mid mounted. McLaren took the original concept car designed by Mercedes and moved the engine 1 metres (39.4 in) behind the front bumper, and around 50 centimetres (19.7 in) behind the front axle. They also optimized the design of the center firewall.

In June 2004 the SLR was tested at Nardo and performed the 0-100 km/h (62.1 mph) exercise in 3.8 seconds, 0-200 kilometre per hour in 10.7 seconds and 0-300 km/h (186.4 mph) in 30.6 seconds.

The "722 Edition" includes an engine rated 650 PS@6500rpm and 820 newton metre@4000rpm, with top speed of 337 km/h (209.4 mph) (3 km/h (1.9 mph) faster than the standard SLR). 19-inch light-alloy wheels were used to reduce unsprung weight, while modifications were also made to the suspension, with a stiffer damper

Exterior changes, other than the larger 19 inches (482.6 mm) black light-alloy wheels, include red "722" badging, harking back to the original 722 racer, and slightly different tail lights and headlamps.
The SLR 722 can accelerate from 0 to 100 km/h (62.1 mph) in 3.6 seconds, 200 km/h (124.3 mph) in 10.2 seconds and 300 km/h (186.4 mph) in 27.6 seconds, and can reach a top speed of 337 km/h (209.4 mph).
A roadster version of the SLR went on sale in September 2007 for £350,000 ($534 485 U.S.). It uses the same supercharged V8 AMG power plant as its coupé siblings, developing 626 PS, to propel it to a top speed of 334 km/h (207.5 mph) and enable 0-100 km/h (62.1 mph) acceleration time of 3.8 seconds.
However, as a convertible the roadster was burdened with extra weight, which affected performance and handling. The Roadster's roof is made from a "newly developed material" and does not take the form of a folding metal arrangement, as is common on many modern cars. Following a manual unlatching, it takes a mere ten seconds to fold away electrically. According to an official Mercedes document, the cabin of the roadster is capable of allowing conversation between driver and passenger up to a speed of 200 km/h (124.3 mph) with the roof retracted. This roadster is aimed to compete against other sports cars such as the Pagani Zonda
The Pagani Zonda is a sports car built by the Italian manufacturer Pagani. It debuted in 1999, and production ended in 2011. As of June 2009, 206 Zondas had been built, including test mules. Both 2-seat coupe and convertible versions have been produced. Construction is mainly of carbon...

with approval from Mercedes-Benz. The car features new wider bodywork to accommodate 19 in (483 mm) OZ racing wheels. The front grill vents are removed and larger, free flowing air extractors sit on the hood and flank the side of the car. The rear now has a racing wing and diffuser.
Under the body, the car has shed 398 kg (877.4 lb) and reduced its dry weight to 1300 kg (2,866 lb) . The engine remains in relatively stock specification but now produces 680 PS and 830 newton metre at 1.75 bar (175 kPa) boost. Inside, the car is stripped out with only the essential functions being available, controlled from a carbon fiber binnacle. New carbon fiber door panels and full roll cage complete the transformation.

race car, and was by Korean designer Yoon Il-hun. It was to be the last series of the McLaren SLR built under the partnership between Mercedes-Benz and McLaren, until McLaren announced their own final edition of the SLR in late 2010.
The supercharged V8 engine is rated 650 PS. The car's top speed is 350 km/h (217.5 mph) with acceleration from 0–100 km/h in less than 3.5 seconds. The car is approximately 200 kg (440.9 lb) lighter than the regular model.
The SLR Stirling Moss began production in June 2009, after SLR Roadster's production ended in May 2009. All 75 cars were produced by December 2009. The SLR Stirling Moss has MSRP of €750,000 and was available only to SLR owners.

McLaren Edition (2011)
In December 2010, more than a year after the SLR was discontinued, McLaren announced a final body conversion of the supercar. The 25-unit limited McLaren Edition is based on any earlier variant of the SLR besides the Stirling Moss and includes revised bodywork (front and rear bumper, grille, top shell, side gills, rear diffuser, rims) and interior parts, along with upgraded steering and suspension components and a new sports exhaust.
So far, the SLR McLaren has been tuned by many specialist companies, including Mansory, Hamann, FAB Design, ASMA Design, Renntech and Brabus. Tuning car company Mansory named their model (which was based on the SLR McLaren) "Renovatio"; changes include the increase in horsepower to 690 PS from 626 PS, and cosmetic changes to the exterior and interior. Hamann named their model "Volcano"; modifications include horsepower increase to 700 PS and cosmetic changes to exterior and interior. FAB Design has turned the SLR into an even faster model, now with a 750 PS, 1080 Nm engine and a complex body kit, named "Desire". ASMA Design decided to call their car "Perfectus" and its engine now produces 700 PS and 885 Nm. Several modifications have been made to the body of the car which is dressed with naked carbon fiber and a re-styled body kit. Renntech made changes to the engine of the 722 version which, after extensive reworking, produces 740 PS. Brabus increased the horsepower of the car from 626 to 650, and made changes in the exterior and interior of the SLR McLaren.
