The only exclusive Audi-tuner from Germany, PPI 
Automotive Design GmbH, breaks through the Audi-tuning arena yet again, and 
presents their new limited production supercar, the PPI Razor GTR-10. The Audi 
specialist turned its focus on optimizing 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 end result is a culmination of knowledge from the past year in research and 
development to create a truly inspired production car; the Razor GTR-10. This 
vehicle will be available to only 10 select individuals.
Performance
Following the introduction of the PPI Razor GTR supercharged V8; PPI 
Automotive Design GmbH has increased their repertoire by refining the Audi R8 
V10 model. PPI Automotive Design utilized all its magic to optimize the 
aerodynamics as well as performance of the series vehicle.
The essential 
part of the motor alteration is the incorporation of race-proven parts. The air 
intake system over the rear engine cover is not only a lightweight component but 
also serves dual duty as a channel for the ram-charged sport air filter system. 
A lightweight high performance exhaust system made of stainless steel has been 
designed and added specifically to work in conjunction with the V10. This is 
tipped off with Ceramic-Coated oval tips. These components are precisely 
adjusted to each other with the help of a new ignition map for motor 
electronics. The result is pure engine refinement of the highest caliber.
The result, after this extensive 
modification, is a normally aspirated V10 engine with over 601 hp (448 kW).
At 7,400 rpm, and a maximum torque of 417 lb-ft (565 Nm) at 6,400 rpm at its disposal. 
Couple the power increase with a weight decrease of 551 lbs (depending on 
options) over its serial counterpart (serial curb weight V10 R-tronic: 3582 lbs). The end result is the ability to achieve speeds from 0 to 
60 mph in mere 3.1 seconds (with modified R-tronic Gearbox) and a maximum top speed of 
208 mph. 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 high-strength formula 1 and aerospace-proven 
carbon fiber technology. All parts are made of this high-tech material, reducing 
weight and adding strength in the process.
The Razor GTR-10 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 incorporated LED day-running unit present the 
two-seater with an even more athletic and aggressive 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 
Razor GTR-10 and also diffuses 
the airflow around the sides of the car for improved aerodynamic stability. The 
inlets of the sideskirts further aid much needed cooling to the engine oil 
coolers and rear brake system.
The roof pillars and doors, like the rest 
of the supercar, are draped in carbon fiber.
In order to perfectly 
balance out the down-force behavior of the front-axle with the rear axle, PPI 
equips the Razor GTR-10 with a special hollow, Carbon Fiber rear wing with an 
adjustable Gurney-flap. The motor cover is made of carbon fiber and incorporates 
glass made of the light high-tech polycarbonate material Makrolon. The engine 
lid also has specially designed Carbon Fiber ram-charged air inlets that replace 
the heavy OE/OEM Engine cover and further aids in cooling the engine as well as 
feeding ram-charged air to the intake system, ensuring the consistent 
performance of the Razor GTR-10. Aiding in the engine cooling, are the newly 
designed side blades, rear fenders and rear bumper that all allow for additional 
motor bay and exhaust cooling that, in conjunction with the Carbon Fiber rear 
diffuser, optimizes the airflow over and through the rear portion of this sharp 
performance car.
Handling
A new widebody skin allows the PPI 
Razor 
GTR-10 the proper structure to accommodate all the performance enhancements, 
including wider wheels and tires. Not to mention enhancement to the overall 
appearance of the car. The Razor GTR-10 utilizes specially designed lightweight 
MAG11 Forged Aluminum PPI wheels. At the front, 9Jx19 MAG11 wheels weighing 
10.0 kg with 245/35 ZR19 Michelin Pilot Sport 2 tires are fitted and an 
impressive 12.0J x 20 MAG11 wheels weighing 10.9 kg with 325/25 ZR20 Michelin 
Pilot Sport 2 tires are used at the rear. This wheel and tire-combination proves 
to be the optimal balance between comfort and control while maintaining proper 
road feedback for the driver.
PPI has also developed a special 
high-performance braking system available for the Razor GTR-10 that can be 
identified by its metallic orange-colored brake calipers. The optimal 
deceleration and perfect pedal pressure control is now achieved by enlarged 
6-piston calipers in connection with extra-large discs measuring 380 x 36 
millimeters at the front and 356 x 32 mm discs at the rear axle providing 
greater pad surface contact area and heat dissipation. Alternatively, the 
vehicle can be equipped with Audi's Carbon Ceramic Brake System with 
PPI-specified higher friction brake pads.
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 Razor GTR-10. And comes equipped with a Hydraulic 
Lift System for the front axle, which can increase ground clearance by up to 45 
millimeters if needed and therefore enables the driver to enter underground car 
parks or drive over speed bumps. This system in combination with PPI's Springs, 
Camber Kit and Tie-rod kit ensure that the Razor GTR-10 stays sure-footed and 
balanced in any situation, whether on the street or race track.
Interior 
"Performance"
PPI completely redesigns 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 Metallic-coloured 
accents and highlights per clients request. Additionally, PPI equips the limited 
edition Razor GTR-10 with extensive Carbon Fiber 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, 
which is present in 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 with steering wheel-mounted Carbon Fiber 
Shift Paddles (R-tronic only).
Highlighting the exclusivity of this 
limited series production is the Razor GTR-10 badging, threshold plates, and an 
aluminum production plaque framed by Carbon Fiber.
