For RENNtech’s 20th anniversary, Hartmut Feyhl who founded RENNTECH in 1989 is celebrating by releasing an extremely modified, street-legal track car limited to 20 units called the McLaren RENNTECH 777 which uses the McLaren SLR as its base and pumps out 777hp!

RENNTECH’s heavily revised SLR McLaren bodywork and aero package includes advanced CFD software to develop the aerodynamics for improved downforce. With the massive wing, splitters, and skirts, a top speed in excess of 210 mph is well within reach for the 777.

The 5.5 L supercharged “Kompressor” v8 engine is heavily revised, with internal and external performance upgrades and a significantly upgraded cooling system.

Getting those 777 horses out to the road requires a fully redesigned suspension & driveline, heavily reinforced transmission with a limited-slip differential which allows for 100% locking between the drive wheels for unsurpassed mid-corner traction.

Earlier this week, AMG boss Volker Mornhinweg announced that “the horsepower war is over.” If this sounds familiar, it’s because AMG issued a similar press release LAST JANUARY.

“Last year, it was a coincidence that we were releasing a new, 695 hp performance package for the 65 series AMG cars at around the same time. We sent out a press release that said ‘HP War Not Over’,” recalls Hartmut Feyhl, president of RENNTECH and four-star General of the horsepower wars. “This year it is the same timing again, and we have something much more extreme to announce for our 20th Anniversary.”

Feyhl founded RENNTECH in 1989, and the company has since established itself as one of the world’s premier tuning firms and the foremost authority on Mercedes-Benz performance tuning. 2009 marks the company’s 20th year in business, and the company intends to celebrate by releasing a small number of extreme, limited edition performance vehicles, beginning with the 777 hp, RENNTECH 777 shown here.

“This 777 concept is really an all-new car that makes use of the advanced carbon fiber chassis of the SLR McLaren. It can be described as a street-legal track car, or something closer to what the enthusiasts were hoping for from the SLR, originally – which is more a successor to the McLaren F1.”

RENNTECH heavily revised the SLR McLaren bodywork and aero package using some of the same technology the company used to develop the the GLK Hybrid Rally Racer for Mercedes-Benz, including advanced CFD software to develop the aerodynamics for improved downforce. Even with the big wing, splitters, and skirts, a top speed in excess of 210 mph is well within reach for the 777.

The 777 is much more than lightweight bodywork, however. The 5.5 L supercharged “Kompressor” v8 engine is heavily revised, with internal and external performance upgrades and a significantly upgraded cooling system.

Getting that power to the ground is the job of a fully redesigned suspension and driveline, with a heavily reinforced transmission sending power to RENNTECH’s revolutionary new limited-slip differential. Built for RENNTECH by Japanese supplier OS Giken, the recently-released differential allows for 100% locking between the drive wheels for unsurpassed mid-corner traction. Aggressive Nitto NT-05 ultra-high performance tires wrapped around extremely lightweight, 1 pc. center-locking wheels round out the street -legal handling package.

“The 777 will be a very special car,” explains Hartmut. “The first example is being built now, and will be ready this Spring. We intend to build a few different extreme vehicles like this for our 20th anniversary, with each one being strictly limited to 20 units. They are all very exciting projects, and we will be announcing them throughout the year, as they approach completion.”

This is the first set of official press photos of the upcoming Mercedes Benz SLR McLaren Stirling Moss. We can expect to see it live in person at the 2009 NAIAS in mid January. A JAW DROPPER ill have to say yes, a MIND BLOWER another yes. It seems to me that they really let loose with this one. Deadly aggressive are the only words that come to mind. No top ads that extra edge of exotic that no car right now has. Only 75 will be made.

Crashing this machine would certainly mean a quick end to your life, yet what a way to go. Of course the SLR McLaren Stirling Moss will be a limited production car, just under 100 will be made, 75 to be exact. Retail on it will be around 750,000 Euros which touches 1.070.000 million USD.

—————— PRESS RELEASE ——————

Stuttgart– Mercedes-Benz and McLaren are adding the crowning glory to the model family of their highly successful SLR super sports car with a new, uncompromisingly spectacular car. There is neither a roof nor a windscreen to separate the driver and passenger from the outside world; they enjoy unadulterated high-speed excitement with all the attributes of a speedster.

The new SLR Stirling Moss is also characterised by the most sophisticated technology and a breathtaking design which reinterprets the SLR legend. With 478 kW/650 hp the SLR Stirling Moss accelerates its V8 supercharged engine from standstill to 100 km/h in less than 3.5 seconds, and has a top speed of 350 km/h – no other series-production car is at the same time so open and so fast. This extreme concept makes the new high-performance sports car a legitimate bearer of the name of the British motor racing legend and Mille Miglia record-holder Stirling Moss, who drove the legendary Mercedes-Benz SLR racing cars from victory to victory during the 1950s.

The exclusive SLR Stirling Moss rounds off the current SLR family and is limited to 75 units. It is priced at 750,000 euros. The SLR Roadster will cease to be manufactured at the end of May 2009 as planned, and production of the SLR Stirling Moss will commence in June 2009.

Three letters are all it takes to make car fans’ hearts beat faster: SLR. In the 1950s the Mercedes-Benz SLR 300 celebrated victory after victory. It won the Mille Miglia and the Targa Florio as well as the Tourist Trophy. It was driven by the stars of the time: Juan Manual Fangio and Karl Kling – and, first and foremost, by the British racing driver Stirling Moss. At ten hours, seven minutes and 48 seconds he still holds the Mille Miglia record.

This is why the modern-day version of the legendary SLR carries the additional words “Stirling Moss” in its name. As the new SLR Stirling Moss unites the character of the current SLR models with the fascination of the SLR of 1955. The core values of both the historical and the present-day SLR models include an exciting new design, innovative technology, high-class materials displaying perfect craftsmanship, and, above all: a unique driving experience for all the senses.

Whilst the 300 SLR earned its spurs on racing circuits the world over, the new member of the SLR family is not designed for the racetrack. Although it sets new standards in terms of technology, performance and excitement – just like its forebears – it is aimed at individuals who have exquisite requirements and nurture very special dreams.

Highly puristic concept without a roof or a windscreen

Remaining totally true to the specifications of the 300 SLR, the new Silver Arrow’s equipment is extremely sophisticated and yet at the same time decidedly spartan, doing without both a roof and side windows. There are just two wind deflectors a couple of centimetres in height to protect the driver and passenger from the airflow. Two air scoops integrated into the bodywork serve as roll-over bars. With this extreme concept the new SLR Stirling Moss is visually very different from all the other vehicles which belong to the elite sports car class.

Just like the legendary racing vehicles of yesteryear, the SLR Stirling Moss dazzles with its superlative performance. Accelerating from zero to 100 km/h in less than 3.5 seconds and with a top speed of 350 km/h this puristic high-performance sports car denotes completely new dimensions in open-top driving. And not just because of the impressive performance figures; every time drivers take to the wheel of the SLR Stirling Moss their senses are addressed with a previously unheard of intensity, conveying a driving experience in its purest and most sensual form. This automotive thoroughbred thus facilitates the kind of open-air feeling that is utterly unique for a road-going vehicle.

Exciting design reminiscent of the SLR racing cars

The SLR Stirling Moss, its entire bodywork made of fine lightweight carbon fibre, represents a stand-alone design concept. Whilst the Mercedes-Benz designers were working on the body of the new SLR Stirling Moss, they were fully aware every single moment that they were creating a vehicle with a top speed of 350 km/h. At the same time this supreme athlete is highly reminiscent of the SLR racing cars from the 1950s, whose design idiom still never fails to impress to this day.

The SLR Stirling Moss sports an exciting, pronounced arrow-shaped form and is characterised by an elongated bonnet and a compact, muscular rear. As there is no windscreen, the exterior and interior flow smoothly into one. The bonnet also stretches from its striking tip right down into the interior, giving the vehicle body a distinctly sleek air. Even when standing still, the sports car radiates such dynamism that the observer immediately falls under its spell.

Further eye-catching features include two air scoops behind the driver and passenger. They carry additional roll-over bars, also uniting the traditional and the modern. The wings are powerfully contoured. Black-painted ventilation “gills” sitting facet-like on the sides and on the bonnet also cite the legend. A thrilling interplay of light and shadow ensues through the expressive lines, underlining the dynamic overall impression. Exactly as they were on the shining historical example, the side skirts on the new SLR Stirling Moss are also very high. This prompted the designers’ decision in favour of folding swing-wing doors which open forwards.

The vehicle can be closed by two tonneau covers which are carried in the boot. When both tonneau covers and the doors are closed the SLR Stirling Moss resembles a sculpture.

In keeping with the puristic exterior of the vehicle, the interior is also reduced to the bare essentials. Surfaces penetrating each other in the instrument panel and doors make for an exciting atmosphere and resonate perfectionism. A mixture of high-class authentic materials such as carbon fibre, aluminium and fine-quality leather sets the style here. An aluminium plate carries the engraved signature of Stirling Moss and covers the area around the shift lever.

Innovative technology and polished aerodynamic concept

Developers working on the Stirling Moss were able to fall back on a wealth of experience gathered when producing the SLR Coupé and Roadster, in particular where the technical base was concerned, with its extravagant carbon-fibre design, high-performance suspension and throaty V8 engine. The common denominator uniting the Stirling Moss with the other members of the SLR family is the aerodynamic concept with a closed underbody and a diffuser in the rear bumper for maximum possible downforce at the rear axle – with one difference: the diffuser here is considerably larger than that on the coupé and roadster.

Thanks to the high-precision work carried out in the wind tunnel, the SLR Stirling Moss always generates sufficient downforce for extremely safe handling. But the driver can also manually operate the AIRBRAKE in order to increase the contact pressure further, during particularly sporty driving, for example. The AIRBRAKE is also raised during powerful braking at speeds above 120 km/h, so as to stabilise the vehicle even more in such situations, thus facilitating maximum possible deceleration.

Limited to 75 units – the SLR models’ crowning glory

The new SLR Stirling Moss is the kind of high-calibre speedster coveted by the sporting gentry and enthusiasts alike. At the same time it is a collector’s item which marks the pinnacle of an era and, for the foreseeable future, at least, the final curtain for the SLR. In May 2009 production of the SLR models will cease; only a total of 75 units of the Stirling Moss will be manufactured between June and December 2009, bearing chassis numbers from 1 to 75. Not only does this exclusive vehicle represent the conclusion of the current SLR family; it also serves as a very special thank you to the most loyal of SLR customers, for they are the only ones able to acquire a Stirling Moss.
