May 1, 1955. 7.22 a.m., Brescia, Italy. Stirling Moss rolls up to the start in his Mercedes - Benz 300 SLR.
The bonnet bears the number "722" - his car’s starting time is also its number. After only a few seconds, the flag drops and one of the most famous drives in the history of motorsport begins : Moss completes the Mille Miglia route from Brescia to Rome and back in just 10 hours, 7 minutes and 48 seconds - a record which still stands to this day.
The spectators give him an enthusiastic reception as his 300 SLR crosses the finishing line, not only winning the Mille Miglia, but also securing its place as one of motorsport’s greatest legends. In 2003 Mercedes-Benz and McLaren revived this legend in the form of the Mercedes-Benz SLR McLaren - the first Silver Arrow of the 21st century.
A few years later, a 722 Edition - an even sportier and even more powerful version - was released. This, in turn, was followed by an SLR in its original form when the SLR Roadster had its world premiere at the 2007 International Motor Show in Frankfurt. And now the time has come to complete the legendary SLR family : with the Mercedes-Benz SLR McLaren Roadster 722 S which will be produced in a limited edition of 150. Effortlessly superior and superbly powerful, it follows in the tracks of its distinguished predecessors.
As the final variant of this model series, it marks the end of the SLR era. And what more fitting conclusion could there be than a unique, breathtaking super sports car with the technology of a Formula 1 racer. It is here and it is time to climb aboard.
The intense, piercing gaze of the headlamps is reinforced by palladium grey surrounds on the SLR 722 Edition. A distinctively shaped airsplitter with a painted exposed-carbon surface enhances the front downforce, especially at high speeds. It splits the air, causing it to flow beneath the vehicle and through the intake openings, thus acting like a front wing.
The SLR simply exudes exhilarating, emotive power. Its design has been discreetly tweaked on both a visual and a functional level. Greater downforce is provided by the modified airsplitter at the front and the airbrake, which can now be raised even further, at the rear. This combination optimises the aerodynamic balance to ensure even better handling and higher cornering speeds on the racing circuit.
Rear Design
The rear design is equally prominent, featuring a diffuser in painted exposed carbon. Darkened tail-light units with palladium grey indicator modules, reversing lights and a third brake light with a smoked glass cover blend perfectly with the carbon surfaces of the exterior. The rear end also sports "SLR" lettering on the left and a modified "McLaren" logo on the right.
The New Light-Alloy Wheels
The 19-inch light-alloy wheels are made of forged aluminium, making them extremely light in weight, which helps to minimise the unsprung masses. The wheels sport a two-tone design. The rim flange is silver whilst the rim spider is palladium grey. Larger, perforated front brake discs (with a diameter of 390 mm, previously 370 mm) and red-painted brake callipers are indicative of the extremely high forces at work here.
Technology
Outstanding performance and safety thanks to carbon fibre technology
In technical terms the 722 S benefits from the long experience of Mercedes-Benz and its Formula-1 partner McLaren. With the exception of two aluminium frames, the body is completely of carbon-fibre materials (CFRP). This makes it highly exceptional among high-performance sports cars. Especially for the roadster, the sophisticated carbon-fibre technology was developed further for the monocoque. The result is low weight, exemplary energy absorption and therefore a high level of occupant safety, plus a torsional rigidity that is unprecedented for an open-top car. It allows outstanding handling characteristics that are otherwise only found in closed super-sports cars.
A high level of safety is provided by unique carbon-fibre crash structures, steel-reinforced A-pillars and two fixed rollover bars. Other safety features include adaptive airbags, knee and sidebags, belt tensioners and a tyre pressure monitoring system.
A thoroughly sporty appearance
The roadster has a crystal antimony grey paint finish, which highlights the sculptured look of this high-performance car particularly effectively. The carbon-fibre technology is visually complemented by the black, grid-like air vents on the bonnet and the front and rear light modules with palladium grey surrounds.
In the interior, outstanding lateral support is guaranteed by sports bucket seats upholstered in a combination of semi-aniline leather/Alcantara. Striking visual highlights are provided by the contrasting seams in 300 SL red, the embossed 722 S lettering on the head restraints and the likewise red seat belts. Frequently used controls such as the shift and parking brake levers are lined in particularly high-grip and moisture-absorbing suede leather. In the interior too, the generous use of carbon-fibre underlines the high-performance philosophy and adds a particularly puristic touch.
SLR 722 S Powertrain and Performance
The powerful heart of the SLR Roadster 722 S is a supercharged 5.5-litre V8 engine which is hand-built in the Mercedes-AMG engine shop in Affalterbach. The special strengths of this high-performance engine include extraordinary responsiveness to movements of the accelerator, a high torque and an unmistakable V8 sound. Moreover, with an output of 478 kW/650 hp and 820 Nm of torque, power is on tap almost to excess (SLR McLaren Roadster: 460 kW/626 hp, 780 Nm). Accordingly the new model variant meets the wishes of the most discerning customers for even more sportiness combined with excellent day-to-day practicality.
The five-speed automatic transmission developed by Mercedes-Benz is designed for high performance. It is specially configured for a very high torque, and allows the driver to choose between two sets of shift characteristics. As a result the roadster achieves performance figures that are even outstanding for the high-end sports car segment: the SLR Roadster 722 S absolves a sprint from zero to 100 km/h in a breathtaking 3.7 seconds, and 200 km/h is reached in 10.6 seconds. The maximum speed is 335 km/h, which is unrivalled by any other series-production roadster.

I've never been a big fan of the styling of the SLRs, but i do have a lot of respect for the cars. The intake is great, but I would hate to work on that engine. The engine looks like a hurricane hit it. The engine does not have the simplistic beauty of a Ferrari engine, i mean the Enzo engine only has 1 belt, that has 3.
