German tuners PPI Automotive have unveiled their Audi R8-based PPI Razor GTR at Top Marques Monaco 2009. The 580hp car is a follow up to the PPI R8 Razor, shown off at the Essen Motor Show in 2008.
That maximum horsepower comes from the engine at 7400 rpm, while torque maxes out at a level of 600 Nm, from 6200 rpm. Weight of the PPI Razor GTR is 1580 kg, a full 250 kg lighter than the PPI R8, and 40 kg lighter than the Audi R8 V10. These modifications get the car from standstill to 100 km/h in 3.7 seconds, on its way to a top speed of 332 km/h. All of these changes came from racing, wind tunnel development, road testing, and track testing. The number one priority was a focus on power-to-weight ratio, without diminishing the car's performance.
Press Release:
World premiere of the Production PPI RAZOR GTR at the “TOP MARQUES MONACO 2009”
The all-new PPI RAZOR GTR limited production Supercar – Intense driving pleasure in a strikingly bold design.
* More POWER
* More STYLE
* More PASSION
The Exclusive German Audi-tuner, PPI Automotive Design GmbH intensifies the fire and presents the special limited production Supercar, the PPI RAZOR GTR.
Performance
Following the introduction of the wildly successful PPI R8 RAZOR at last year’s Essen Motor Show, PPI Automotive Design GmbH have used all its knowledge from the past year in competition, closed road races, open road races, and research and development in the wind channel, autobahn and track testing, to create a truly inspired production car. The Audi specialist turned its focus on optimising the power-to-weight ratio of the Audi R8 while simultaneously strengthening the motor, increasing performance, improving handling dynamics, and managing to reduce the weight of the Audi R8.
The essential part of the motor alteration is the incorporation of a specially engineered supercharger. In addition, a ram-charged sport air filter system and a high performance exhaust system made of stainless steel have been designed and added specifically to work in conjunction with the supercharger system. These components are precisely adjusted to each other with the help of a new ignition map for motor electronics.
The result, after this extensive modification, is a car with up to 580hp / 427 kW at 7,400 rpm, a maximum torque of 600 Nm at 6,200 rpm at its disposal, and a weight decrease of 250 kg over its serial counterpart (serial curb weight 1,580 kg). Providing the PPI RAZOR GTR with the ability to achieve speeds from 0 to 100 km/h in only 3.7 seconds with a maximum top speed of 332 km/h. This insures the proper performance to easily meet the demands of its motorsports and enthusiast clientele.
Aerodynamics
In addition to the excellent driving performance, this PPI Supercar also has a striking widebody appearance with elaborate, wind tunnel tested aerodynamics. Special attention was paid to the reduction of the vehicle’s weight, which was achieved by PPI’s extensive use of the extremely light and high-strength formula 1 and aerospace-proven Carbon Fibre. All parts are made of this high-tech material, reducing weight and adding strength in the process.
The PPI RAZOR GTR front bumper replaces the serial bumper and the new design in conjunction with a specially engineered front diffuser, reduces lifting forces at the front axle. Larger air inlets in connection with a new full LED-headlight unit present the two-seater with an even more athletic face. More importantly, these air inlets feed the radiators with additional fresh air and channels through the new front hood to provide optimal cooling to the brake system. PPI sideskirts highlight the sporty profile of the GTR and also diffuses the airflow around the sides of the car for improved aerodynamic stability.
In order to perfectly balance out the down-force behaviour of the front-axle with the rear axle, PPI equips the RAZOR GTR with a special rear wing with an adjustable Gurney-flap. The motor cover, made of the light high-tech polycarbonate material Makrolon®, also has specially designed Carbon Fibre ram-charged air inlets that replace the heavy OEM Engine cover and aid in cooling, ensuring the consistent performance of the RAZOR GTR. Aiding in the engine cooling, are the newly designed side blades, rear fenders and rear bumper allow for additional motor bay and exhaust cooling that, in conjunction with the Carbon Fibre rear diffuser, optimises the airflow over and through the rear portion of this sharp performance car.
Handling
The overall appearance of the car is further enhanced by a new widebody skin to allow the PPI RAZOR GTR the proper structure to accommodate all the performance enhancements and wider wheels. The RAZOR GTR utilizes specially designed lightweight MAG9 Carbon Fiber forged aluminum PPI wheels. At the front, 10Jx19 MAG9 wheels weighing 8.8kgs with 255/35 ZR 19 Michelin Pilot Sport 2 tyres are fitted and an impressive 12.0J x 20 MAG9 wheels weighing 10.0 kgs with 325/25 ZR 20 Michelin Pilot Sport 2 tyres are used at the rear. This wheel and tyre-combination proves to be the optimal balance between comfort and control while maintaining proper road feedback for the driver.
PPI also developed a special high-performance braking system available only for the RAZOR GTR that can be identified by its metallic orange-coloured brake callipers. The optimal deceleration and perfect pedal pressure control is now achieved by enlarged 6-piston callipers in connection with extra-large discs measuring 380 x 36 millimetres at the front and 356 x 32 mm discs at the rear axle providing greater pad surface contact area and heat dissipation.
Nothing has been left untouched, as is evidenced by the new coil over kit developed in conjunction with technology partner KW Automotive GmbH. This system has been specially adjusted to the needs of the PPI RAZOR GTR. And comes equipped with a Hydraulic Lift System, which can increase ground clearance by up to 45 millimetres if needed and therefore enables the driver to enter underground car parks or drive over speed bumps.
Interior “Performance”
PPI completely re-designs the interior and turns the R8-interior into a “members-only” lounge with a motorsports flair. The serial interior is replaced by highest quality Onyx Nubuck-leather with orange-coloured accents and highlights. Additionally, PPI equips the limited edition RAZOR GTR with extensive Carbon Fibre throughout the cockpit; hand-brake lever, door sill protectors, Driver and Radio Console Surround, Door Trims, Center Console inserts, and kneepad trims, the ultra-light folding sport seats are also made of Carbon Fibre and bear the PPI “Sport Identity” style, following with the headliner, the steering wheel, shift knob, door panels and center console. The technical highlight of the interior is the ergonomically re-designed PPI sport steering wheel. Highlighting the exclusivity of this limited series production is PPI RAZOR GTR badging, threshold plates, and an aluminium production plaque framed by Carbon Fibre.
