The flawless roads today lead through the next to Dubai are ideal for the pedigree sporting performance characterises the Mercedes-Benz SLR McLaren 722 Dubai is the up-and-coming business of the United Arab Emirates It is the setting for the world’s most construction projects, including the Palm Jumeirah island, and the course of recent decades wealthy sheikhs have avid automobile aficionados. It is flair for the exceptional that the desert city on the Persian and its inhabitants with the Mercedes-Benz SLR 722 Edition premium sports

The new SLR 722 Edition model variant Mercedes-Benz evokes memories of a special victory achieved in by the British motor-racing legend Moss and his co-pilot Dennis at Mille Miglia the classic endurance race behind the of a Mercedes Benz 300 SLR with number 722 (denoting the car’s time of 7.22 a.m.). an impressive output of 478 kW/650 hp, the new SLR 722 Edition super sports car not outperforms its historic forefather, it outstrips the scintillating peak of the current SLR model. The new limited-edition only 150 models are being for the most part handcrafted, at the Formula 1 works in Woking is the response to calls from discerning SLR customers for even sportiness combined with the high level of everyday

At the heart of the SLR 722 Edition is a 5.5-litre V8 assembled by hand at the Mercedes-AMG workshops in Affalterbach, Germany, on the One man, one engine principle. the high-performance powerplant’s major are its exceptionally spontaneous response to pedal movements, high and that unmistakable V8 sound.


with dry-sump lubrication

The entire engine block its enclosed crankcase sump is from cast aluminium. crankshaft is precision-weighted and revolves in bearings made from a material to enable sustained of the tremendous forces emanating the supercharged engine.

The forged are only manufactured in extremely numbers. Just like the lightweight connecting rods, the are measured and weighed with accuracy before being to individual engines. This any mass balancing tolerances to an minimum. The pistons slide extremely durable, wear-resistant, cylinder barrels made a special compound which is only found in race car Twin oil injection is used for piston cooling.

The oil cooling technology employed for the unit as a whole also on the brand’s racetrack experience: a dry-sump lubrication system a capacity of around eleven combines with a five-speed oil pump and a two-speed oil pressure to guarantee reliable lubrication all driving conditions. One important effect of this dry-sump technology, which is again exclusive to race cars, is the engine height can be kept allowing it to be installed deeper in the engine compartment: the result is a low of gravity that fosters handling.

Screw compressor

Efficient cylinder charging is the of a belt-driven compressor with two aluminium rotors that are in the interests of keeping friction In order to keep the engine as efficiently as possible at all times, the AMG have devised an intelligent management system which determines when to deploy the compressor as the engine’s rev speed and change. Consequently, the supercharger is called into action it is really needed. Notwithstanding however, maximum power is available the instant the driver it by opening the throttle.

Apart the compressor, the engine’s electronics all of the other variables which are to its operation. At the same time, ensure optimum operation of the water circuit. After efficient cooling of the charge air is a ingredient for high performance.

The operate based on the extremely air-to-water heat exchanger the air which has been compressed by the causing it to heat up, is directed a separate water circuit to it down again. This the eight-cylinder powerplant to maximise its and torque delivery.

Manual mode for shift times of a race car

High performance has been ingrained into the automatic transmission, which was in-house at Mercedes-Benz and has already in a number of exceptionally powerful It has been optimised to enable it to the awesome torque on tap and also drivers the possibility of varying the characteristics. The transmission directs the power to the differential and the rear via a precision balanced drive made from aluminium and

The interplay of the engine with the was also subject to modification. For of the individually selectable transmission M (Manual) and S (Sport) on the one hand and C on the other there is now a different pedal characteristic curve, has been optimised in line the varying operating conditions.

The end is an extremely impressive set of performance even by high-end super car standards: the SLR 722 Edition completes the from 0 to 100 km/h in a breathtaking 3.6 (SLR 3.8 seconds), with the needle proceeding to pass the 200 mark in a mere 10.2 (SLR 10.6 seconds) and the 300 mark in just 28.0 (SLR 28.8 seconds). the top speed of 337 km/h is even than that of the current SLR km/h).

New chassis set-up for enhanced handling dynamics

One of the driving forces behind the performance of the SLR 722 Edition is the retuned Devel opment work at Formula 1 headquarters was based on the of the SLR’s proven aluminium that is itself the handiwork of race car developers: wheel is the task of double wishbones at the front and rear. The bottom are arranged in such a way that the receive a negative camber the springs compress or when at speed. This guarantees contact with the road in any Meanwhile, the axle technology minimises the degree of diving and while braking heavily and respectively.

The axle’s wishbones are from forged aluminium, cast aluminium is used for the carriers. This lightweight boasts a host of advantages to conventional steel constructions, the far superior response of the suspension and that results from the weight.

The relatively long wheelbase of millimetres likewise contributes to the handling characteristics, with the notable benefit being the straight-line stability, while the track combines with the low of gravity to enable high speeds.

The chassis construction has the bar positioned above the front where it is controlled via rocker just like on a Formula 1 With this set-up, the bar does not take up any additional space. In this way, the lines of the underside of the vehicle are not which is vital for the sports outstanding aerodynamic characteristics.

In the phase of chassis development for the McLaren 722 Edition, various of chassis parameters, such as and damping, underwent a series of on the Formula 1 dynamometer in Woking. the Mercedes-Benz and McLaren engineers further refinements and finalised the new by performing an extensive series of on the road and, above on the race track.

The stiffer rates and shock absorber of the chassis as well as the lowering of the by 10 mm at both the front and rear are gives the SLR 722 Edition its increased stability and noticeably further handling dynamics. Body on bends has been reduced by 20 percent, allowing the new SLR 722 Edition to at even greater speeds.

New forged aluminium wheels help to improve the handling of the special-edition model, their palladium grey design the car’s motor-racing heritage. lower weight compared to wheels reduces the unsprung making the responsiveness of the SLR 722 Edition all the Plus, the 19-inch wheels larger brake discs a diameter of 390 mm to be fitted on the front Hailing from the Italian Brembo, the new braking system with the carbon-fibre-reinforced ceramic to provide formidable decelerating which is fully in keeping the SLR 722 Edition’s scintillating all-round Exhaustive testing was carried out to a new ESP® control system for new brake configuration.

High-tech material for exemplary and maximum strength

The high-performance car’s bodyshell bristles high tech. The entire including the crash structures at the and rear, the occupant cell, the doors and the bonnet, is made carbon-fibre-reinforced plastic (CRP). lightweight yet, at the same extremely rigid material is a borrowed from the aviation and travel industry and has already its worth in ultra-sophisticated Formula 1 cars. Despite the weight-saving of 50 that this high-tech represents compared to steel, it is as strong, which allowed the to focus on achieving the body’s strength.

Plus, in the event of an carbon fibres have a energy absorption that is four to five time than steel or aluminium. has capitalised on this material by also fitting two 620-millimetre-long member elements made carbon fibre in the front of the SLR 722 Edition; these are capable of all of the impact energy in a head-on without exceeding the maximum of deceleration that the occupants are to withstand. In the event of an impact, the of these two elements tear front to rear to crumple in a predetermined manner and thereby a constant rate of deceleration.

The sports car’s occupant is likewise made from high-tech material, offering a very rigid and therefore survival space in an accident. At the of the car, the task of absorbing in a crash falls to two internal members made from carbon fibre and a sturdy member, which together that the occupant cell virtually intact. The occupant system also encompasses front airbags, which are in two stages depending on the severity of the head/thorax bags and knee as well as seat belt and belt force limiters.

An work of art: even downforce and an improved cd figure

100 hours of meticulous work in the tunnel also helped the performance of the SLR 722 Edition. Here the performed yet another technical by increasing downforce whilst at the time reducing the cd (drag figure. It’s all thanks to the at the front end of the SLR 722 Edition. Consisting of with a clear-coat finish, the shaped spoiler lip not only aerodynamics, it also increases the at the front axle by 128 percent. wheel spoilers, also in carbon, reduce air swirl at the axle, making for a smoother and optimising road feel. The combine with the airbrake at the to produce a further substantial in the downforce acting at the rear of the new SLR 722 Edition. The result is even precise handling and turn-in at speeds.

The rear-mounted airbrake is designed to directional stability and braking when the speed exceeds 120 it automatically rises up at an angle has been adjusted in line the extremely dynamic performance of the new If the driver hits the brakes at high speed, the airbrake up into the airstream automatically. dynamic modification increases downforce within a fraction of a thus partially compensating for the axle load distribution braking, which presses the front axle.

A further which contributes to the distinctly configuration is the weight of the SLR 722 Edition, the engineers have managed to by around 44 kg. A lighter oil tank and bodies made from which have the added of improving the vibration response of the masses, contribute to this loss. Last but not least, panelling and insulating materials have a positive effect on the weight. Yet for all these measures, the levels of comfort, safety and that have become hallmarks remain unaffected.

design through and through

In of exterior design, the SLR 722 Edition discreet sporty touches, satisfying the desires of keen drivers and affluent sports-car the core target group to the The new-look 19-inch light-alloy afford a perfect view of the brake callipers and the large discs, emphasising the sheer and performance that underpins aspect of the SLR 722 Edition.

In addition, components in carbon with a finish highlight the close with Formula 1. Plus, the design of the black-painted air outlets on the not to mention the front and rear clusters with their grey surrounds, blend in with the carbon-fibre look. The SLR 722 is available with a crystal grey paint finish creates a vivid impression of and produces an extremely intensive-looking structure.

Moving inside, the sports seats, upholstered in a combination of leather and Alcantara, offer lateral support, while the contrast provided by the distinctive 300 SL red throughout the interior, the 722 insignia on the restraints and the red seat belts is for added visual impact. The material mix comprising semi-aniline and Alcantara, which gives the its characteristic look and feel, features prominently on the roof and door panels. Frequently controls, such as the shift and handbrake lever, are trimmed in moisture-absorbing suede. The sporty philosophy that is at the heart of the SLR 722 is also reflected by the widespread use of throughout the interior. This straight from the world of 1, lends the centre console an puristic look.

The restyled cluster focuses the driver’s on the key vehicle data, comprising round dials with a background. The functionality of the multifunction is given an extra sporty in the form of the AMG RACETIMER. Finally, the paid special attention to the wheel as the key link between and car: with its combined trim, the rim is extremely easy to and helps the driver to stay in control when performing manoeuvres, as do the new aluminium shift
