The SLR is the arena's first series-produced automobile to have a the front crash shape synthetic absolutely from carbon fibres. Adaptive airbags, newly advanced kneebags and sidebags, belt tensioners, excessive-overall performance ceramic brake discs and an robotically adaptive airbrake withinside the boot lid spherical off the variety of protection system on board the Mercedes-Benz SLR McLaren, placing new requirements on this car elegance.Technology manner in advance of its time and an abundance of energy - those have been the hall-marks of the mythical SLR race motors wherein Fangio, Moss, Kling and different Mercedes drivers accomplished dazzling victories in all the essential avenue races in 1955. The Mercedes-Benz SLR McLaren demonstrates the identical traits, its groundbreaking technical improvements distinguishing it because the Mercedes-Benz amongst excessive-overall performance sports activities motors.
The frame layout of the Gran Turismo with the Mercedes big name takes classical styling factors from the mythical SLR race motors of the Fifties and blends them masterfully with the state-of-the-art, avantgarde layout language of each the modern day Mercedes passenger automobile fashions and of the cutting-edge-day Silver Arrow race motors which took the McLaren Mercedes group to Formula 1 World Championship glory in 1998 and 1999. The layout's idea, in different words, thrillingly spans the divide among beyond and gift, while on the identical time displaying the manner ahead for the sports activities automobile designs of tomorrow.In order to satisfy the best of requirements in phrases of coping with at pinnacle velocity, directional balance and the cooling air necessities important for excessive-overall performance motors of this kind, Mercedes-Benz labored with McLaren on growing this model's superlative aerodynamics, making sure exemplary roadholding plus the on-avenue protection requirements traditional of Mercedes. Following vast wind-tunnel tests, the Mercedes-Benz SLR McLaren turned into given a without a doubt easy underbody with a unique six-channel diffusor below the rear. Both functions are acquainted layout ideas from Formula 1. They make sure that the airflow underneath the car is without a doubt unimpeded and that terrible lift, or downforce, is produced at better speeds.
The special sidepipes on every aspect of the car also are the end result of this excessive-overall performance sports activities automobile's aerodynamic underbody idea: a traditional exhaust fueloline machine might have disrupted the easy line of the underbody.At the rear of the Mercedes-Benz SLR McLaren an adaptive spoiler affords extra downforce. From a velocity of ninety five km/h, it robotically adopts a 10-diploma function, growing the touch stress on the rear axle. The spoiler additionally doubles as an airbrake: whilst the driving force brakes heavily, it rises to an perspective of sixty five stages, now no longer best making sure elevated aerodynamic drag however additionally moving the aerodynamic centre similarly toward the rear. This lends the Mercedes-Benz SLR McLaren notable balance whilst braking from excessive speeds.
It is the very excessive stages of practicality and comfort that simply make the indoors of the Mercedes-Benz SLR McLaren stand out. Individually padded carbon-body seats, a multifunction guidance wheel with race-automobile-kind buttons for guide equipment selection, honestly organized chronometer-fashion devices and excessive-grade substances outline the environment in the excessive-overall performance sports activities automobile.
The layout's idea consequently spans the divide among beyond and gift and cre-ates a automobile with a completely unique charisma - a Mercedes synthesis of legend and innovation that's brilliant in each respect.It is the the front quit particularly which singles out the brand new Mercedes-Benz SLR McLaren as an immediate descendent of the racing motors that have been so a hit in current instances: the centre is ruled via way of means of the distinguishing, arrow-formed nostril of the Formula 1 Silver Arrow, encompassing the Mercedes big name on the the front, an unmistakable hallmark of producing origins which are steeped in culture.Underneath the nostril may be determined a similarly traditional styling detail taken from the Formula 1 race motors which took McLaren Mercedes to the World Championship crown in 1998 and 1999: the twin-fin the front spoiler with the distinctively curved struts. As at the Silver Arrows, those aerofoil fins are greater than only a elegant figuring out characteristic, they're without a doubt critical to the automobile's aerodynamics.
The excessive touch pres-certain they produce on the the front axle performs a key position withinside the Mercedes-Benz SLR McLaren's certain-footed, race-automobile-like roadholding.The fin layout turned into followed as a routine characteristic of the Mercedes-Benz SLR McLaren's outdoors, thereby main-taining a excessive degree of layout consistency: finned sections additionally separate the head-lamps from the nostril, shape the bottom for the 2 outdoors mirrors and embellish the tail lighting on every aspect of the automobile, in which the indicators' LEDs are housed in self-helping fins located one above the opposite.Above the generously proportioned air consumption for the engine cooling is the huge, flat bonnet, whose rear aspect lies beneath the start line of the A-pillars, allowing the deep-set layout of the the front windscreen. This is every other traditional detail taken from the arena of motorsport which offers drivers the best degree of visibility wanted for excessive-velocity motoring.The headlamp association is a refreshingly new edition of the relatively acquainted and similarly a hit twin-headlamp face, which has been the calling card of Mercedes-Benz passenger motors considering the fact that 1995. In this SLR-fashion reinterpretation, al-aleven though the dipped-beam and main-beam headlamps shape a unmarried unit, they by no means-theless achieve emphasising their simple, pronouncedly oval shape. The layout group has bolstered the effective visible impact via way of means of sheathing the effective projection head-lamps in casings which resemble awesome digital digicam lenses, all housed in the back of clean glass.As with all modern Mercedes passenger motors, the oval traces of the twin-headlamp face shape the beginning factors for modelling the bonnet and the wings.
The rounded contours of the headlamps turn into effective domed curves which pretty intentionally evoke institutions with the human anatomy: the curves expand lower back over the wings just like the sinewy muscle tissues of a educated athlete, leaving no question in anyone's thoughts that this automobile bristles with the natural energy of a carrying superstar.
These contours - tender but brimming with energy and dynamism - integrate with taut traces to provide a fascinating, sculpted outdoors shape, a clean expression of the uncompromising way wherein this automobile's excessive-overall performance credentials were honed. The automobile flexes its muscle tissues visibly however with none trace of aggression, with every fibre of its lithe frame trimmed and tensed, prepared to release ahead at any time.
The domed curves main off from the internal pair of headlamps sweep seamlessly all of the manner lower back to the A-pillars, forming a easy visible hyperlink among the the front quit and the passenger compartment. As they run up the lengthy bonnet, the softly rounded domes once more rework into taut, clean-reduce traces, which in flip mold the arrival of the A-pillars and the aspect profile.
This is likewise one of the factors underpinning the function, effective proportioning of the SLR silhouette: the lengthy bonnet, taut midriff, compact passenger compartment and brief tail create a planned affiliation among the glide of the SLR's traces and the styling factors of Mercedes sports activities motors from years long past via way of means of, and symbolise the feel of forwards surge that guides thru the Mercedes-Benz SLR McLaren.The excessive-overall performance sports activities automobile exudes the identical effective, but harmonious influence whilst visible from the rear too. This is right all the way down to the stylish manner wherein the traces glide from the passenger compartment into the lid of the boot, helped via way of means of the slim roof pillars which taper toward the bottom. Unlike the SLR Silver Arrows of the Fifties, whose tail curved lightly downwards, the boot of the Mercedes-Benz SLR McLaren maintains on the identical excessive degree in an effort to beautify the aerodynamic characteristics.
The huge tail lighting are a direct eye-catcher. The special, triangular shape of the obvious lenses, a standard characteristic of Mercedes passenger motors, has a wrap-round layout which extends a ways into the aspect panelling to emphasize the width of the frame.It is above all of the aspect profile of the excessive-overall performance sports activities automobile that identifies it as a automobile whose maker has a protracted and illustrious motor-racing culture, with huge, finned air openings respiration new existence into the SLR legend. These "gills" are a ways greater than an insignificant styling contact, serving now as they did lower back then to ventilate the engine compartment. The designers of the Mercedes-Benz SLR McLaren have lent similarly emphasis to this precise characteristic via way of means of enlarging the floor of the fins toward the rear of the gills, and via way of means of setting a clean-reduce line on the quit of the fins which then sweeps similarly backwards to feature to the styling of the swing-wing doorways.If there may be one special characteristic that the brand new Gran Turismo has followed from the Uhlenhaut Coupé, the coupé model of the mythical SLR race automobile, designed in 1955 via way of means of Mercedes' head of trying out at that time, Rudolf Uhlenhaut, it's miles the doorways.In their cutting-edge interpretation, however, they're connected to the the front roof pillars as opposed to to the roof itself and swing forwards and upwards in a huge perspective. No much less sensational than the gullwing layout from the Fifties, this new idea additionally enlarges the doorway to the car to make going into and out clean for each driving force and passenger.Inside, each element of the indoors displays the excessive-overall performance person of the Mercedes-Benz SLR McLaren. Take your area on board, and you will sense the joys of sitting in a thoroughbred sports activities automobile. The on-board environment, however, is likewise one in all protection and calm - key necessities in which concentrated, rapid riding is concerned.
The cause in the back of that is a honest but very emotional layout language. It takes up the fin layout and maintains it continuously withinside the indoors.

Engine and transmission: V8 powerplant with motor racing in its genes
An abundance of energy and excessive-tech functions from the arena of motorsport - those are the defining traits of the V8 engine withinside the Mercedes-Benz SLR McLaren. Which approach that the primary eight-cylinder to be absolutely advanced via way of means of Mercedes-AMG suits flawlessly into the excessive-overall performance idea of the brand new Gran Turismo.
When growing the powerplant, the AMG engineers carried out each the understanding that they'd obtained for the duration of their 3-decade involvement in motorsport and the stringent requirements of the Mercedes-Benz brand. After an in depth idea phase, they determined in favour of an eight-cylinder layout with a 5.5-litre displacement, a cylinder perspective of ninety stages, a screw-kind compressor and a crankshaft supported via way of means of 5 bearings.The end result is brilliant: from an insignificant 1500 rpm, the SLR powerplant gives you torque of over six hundred Newtonmetres, growing to seven hundred Newtonmetres at 2000 rpm. The most of 780 Newtonmetres is to be had from 3250 rpm and stays consistent in a extensive engine velocity variety as much as 5000 rpm. The splendid torque curve, coupled with the agile reaction of a sporty engine which by no means denies its excessive-overall performance person (it gives a height output of 460 kW/626 hp at 6500 rpm - an enormously excessive engine velocity for this displacement size) communicate a effective language. As the figures indicate, the Mercedes-Benz SLR McLaren is endowed with what's presently one of the maximum effective engines to be determined in a series-produced roadgoing sports activities automobile. An evaluation of the important thing statistics:
Cylinder association: V8
Cylinder perspective: ninety
Valves in step with cylinder: 3
Displacement: 5439 cc
Bore/stroke: 97.zero/92.zero mm
Cylinder spacing: 106 mm
Compression ratio: eight.eight : 1
Output: 626 hp (460 kW) at 6500 rpm
Max. torque: 780 Nm at 3250-5000 rpm
Engine weight: 232 kg
Power/weight ratio: 1.nine kW/kg
With this tons energy below the bonnet, the Mercedes-Benz SLR McLaren's overall performance figures are many of the nice in its elegance:
zero-a hundred km/h: 3.eight s
zero-2 hundred km/h: 10.6 s
zero-three hundred km/h: 28.eight s
Top velocity: 334 km/h
Fuel consumption: 14.eight litres in step with a hundred kilometres (NEDC mixed consump-tion, provisional determine)
Power from screw-kind compressor
To make sure top cylinder charging, the engine has a mechanical compressor with screw-kind aluminium rotors which, withinside the pastimes of low friction losses, are Teflon-coated. The charger is so compact that the engine experts have been capable of deployation it among the 2 cylinder banks of the V8 powerplant.
Despite the area-saving layout, its modern era permits a considerably better rate stress than traditional mechanical chargers due to the fact the 2 rotors obtain a pinnacle velocity of round 23,000 revs in step with minute, forcing air into the air inlet of the 5.5-litre powerplant at a most stress of zero.nine bar. This approach that they compress round 1850 kilograms of air into the 8 combustion chambers in step with hour - that's as much as 30 percentage greater than the determine accomplished via way of means of rival charging systems.In order to make sure the finest viable efficiency, the AMG engineers created an shrewd engine control machine which regulates the operation of the screw-kind compressor consistent with the engine velocity and load. This approach that the charger is best lively whilst it's miles wanted. Nevertheless, the machine guarantees that the most output is to be had as quickly because the driving force calls it up via way of means of stepping at the accelerator. When this occurs, the electronics of the engine control machine cause an electromagnetic coupling which right away turns on the compressor, that's powered via way of means of a separate poly-V-belt. Because the charger de-livers its output in fractions of a second, even the maximum perceptive driving force will now no longer be aware the stages with out charger support. The charger machine's air recirculation flap, opened below partial load, facilitates lessen gasoline consumption.In addition to the compressor, the electronics additionally screen all different variables applicable to the engine - each the powertrain control for the pedal-based force traits and the implementation of spontaneous transmission or ESP® interventions. They additionally make sure greatest manipulate of the water circuit for the rate-air cooling machine, as green rate-air cooling is important in which excessive output is concerned. This is due to the fact bloodless air is denser than heat and additionally con-tains considerably greater oxygen for combustion. In the Mercedes-Benz SLR McLaren's V8 engine, separate rate-air coolers are answerable for this key task - one in step with cylinder. This guarantees that lack of stress could be very low.The relatively powerful engine-primarily based totally rate-air coolers perform alongside the traces of an air/water warmth exchanger: the air, compressed and therefore warmed via way of means of the compressor, is cooled thru a separate water circuit - making the technique unbiased of the temperature outside. This approach that the eight-cylinder can supply its maxi-mum output and torque spontaneously at any time.
The excessive overall performance figures of the eight-cylinder engine withinside the Mercedes-Benz SLR McLaren, however, now no longer best call for top cooling of the combustion air however additionally bring about an average growth in engine cooling necessities. The engineers met this want via way of means of incorporating beneficiant cooling air inlets and retailers and a effective 850-Watt suction-kind fan.The Mercedes-AMG GmbH engineers additionally carried out their vast revel in withinside the global of motorsport and withinside the layout of excessive-overall performance engines to different info of the SLR powerplant. The whole engine housing, for instance, and the decrease phase of the closed crankcase are solid in aluminium. Each crankshaft is finely balanced and is supported via way of means of 5 bearings crafted from long lasting plastic, permitting lengthy-time period switch of the brilliant forces from the compressor engine.The pistons are cast and are consequently best synthetic in minimum numbers. Like the cast light-weight conrods, they're exactly measured and weighed and allotted to the character engines in this sort of manner as to provide minimum balancing tolerances. The pistons circulate in relatively strong, wear-resistant and friction-optimised partitions crafted from a unique compound that's in any other case best utilized in motor racing. Dual oil injection correctly cools the pistons.The layout of the powerplant's oil cooling machine is likewise primarily based totally on revel in amassed withinside the global of motor racing: an advanced dry sump lubrication machine with an oil capability of round 11 litres, mixed with a 5-degree oil suction pump and a -degree oil stress pump, guarantees dependable lubrication below all on-avenue situations. An critical aspect impact of this era is that, due to the dry sump lubrication, typically best utilized in motor racing vehicles, the engine is much less tall and might consequently be hooked up at a decrease degree, permitting a low centre of gravity which blessings dynamic coping with.Following the standard exercise at Mercedes-AMG, every SLR engine is synthetic via way of means of hand. In order to obtain the best excellent, the precept of 'one man, one engine' is carried out. This approach that every powerplant is the duty of 1 AMG engineer, who contains out the whole engine meeting technique - from putting in the crankshaft withinside the engine block and assembling the camshafts and the compressor to cabling.
The Mercedes-Benz SLR McLaren's excessive-overall performance engine attracts its gasoline from interconnected aluminium tanks. They are hooked up at a enormously low degree to the left and proper of the rear axle in an effort to maintain the centre of gravity as little as viable to similarly en-hance dynamic coping with.
The tanks, that have an average capability of 97.6 litres - of which twelve litres shape the reserve - are ready with critical excessive-stress gasoline pumps. These are managed via way of means of the engine control machine and make sure that the gasoline deliver fits the engine velocity and load. Here too a relatively powerful, SLR-unique answer turned into advanced: one pump operates continuously at the same time as the second one is best activated as required.Where the engine is concerned, secondary air injection and twin ignition create the standards required for low exhaust fueloline emissions. A state-of-the-art exhaust fueloline machine enhances those measures: the cascade-layout twin-pipe machine is composed on each aspects of a bulkhead-hooked up catalytic converter and a prime catalytic converter with a unique noble steel coating, accommodated withinside the identical housing. The modern steel layout permits extraordinarily skinny wall thicknesses and consequently a totally low exhaust fueloline backpressure. Thanks to its contemporary-day era of its engine control and emission manipulate systems, the brand new SLR's eight-cylinder engine already meets the stringent exhaust fueloline limits stipulated via way of means of EU four plus the modern US limits.
On every aspect of the car the catalytic converter housing opens right into a rear silencer which, simply in the back of the the front wheels, flows into stainless-steel pipes with a diameter of 60 millimetres. These sidepipes - a similarly reminder of the Fifties SLR racers - permit the easy-surfaced underbody, which performs a critical position in generating the brand new Mercedes-Benz SLR McLaren's fine aerodynamic properties. The silencers are folded numerous instances in exactly calculated acoustic sections which produce the exciting function engine sound of the Mercedes-Benz SLR McLaren.
The capability of every silencer is 19.6 litres.The 5-velocity computerized transmission, advanced via way of means of Mercedes-Benz and already effectively utilized in numerous fairly effective fashions, is likewise designed for excessive overall performance. It has been particularly optimised for terribly excessive torque and additionally gives the driving force the choice of selecting among special shift traits. The transmission transmits the engine energy thru a finely balanced aluminium and metallic powertrain to the differential and the rear axle.The Speedshift machine, advanced via way of means of Mercedes-AMG for specifically sporty riding, gives even greater capabilities withinside the Mercedes-Benz SLR McLaren. The driving force can decide, for instance, whether or not to go away the shift paintings to the automated transmission or to shift gears manually.
