Audi R8: The Razor GTR by PPI

[The RS6]

http://www.motorauthority.com/content/images/p/p/ppi_razor_gtr_audi_r8_main630_01-1120.jpg

PPI has created an Audi R8 mod called Razor GTR.
Picking up the ‘GTR’ designation, the latest model builds on the success of the original using knowledge PPI engineers have gathered over the past year from racing, wind tunnel development, and autobahn and track testing. The highlight of the package is an increased focus on optimising the power-to-weight ratio of the Audi R8, with engineers simultaneously boosting power while reducing weight.

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 this new forced-induction system.

The end result is a car with 580hp (427kW) and 600Nm of torque. At the same time, the R8’s 1,580kg kerb weight has been reduced by more than 250kg, enabling the Razor GTR to accelerate from 0 to 100km/h in only 3.7 seconds and reach a top speed of 332km/h.

The end result is a car with 580hp (427kW) and 600Nm of torque.

That's 5.04 LBS per HP. That's a GREAT weight reduction!
This W/P ratio is an easy tool to use in comparing hi-performance sports/track car. But it is just a starting place. There are many, many other significant variables that finally determine a car's ultimate abilities.

Audi R8 PPI Razor GTR 2926 LBS/ 580 HP = 5.04 :R8kiss:

Audi R8 3400 LBS/ 420 HP = 8.09 :R8kiss:

Porsche GT3 RSR 2420 LBS/ 445 HP= 5.43

Porsche GT2 3175 LBS/ 530 HP = 5.99

Porsche GT3 3000 LBS/415 HP = 7.22

Porsche TPC TT Cayman S (my other car) 2950 LBS/485 HP= 6.18

Ferrari 430 Scuderia 2755 LBS/ 510 HP = 5.40

Ferrari Enzo 2767 LBS /660 HP = 4.1

Dodge Viper ACR1 3408 LBS/600 HP = 5.68

Corvette ZR1 3350 LBS/620 HP = 5.4

Lamborghini Gallardo 3109 LBS /552HP = 5.63

Nissan GT-R V Spec 3636 LBS/520 HP = 6.99

Looks fun. Next up, supercharged V10 Razor.

That's one serious R8, but I love it. Looks good, engine sounds promising and best of all... Weight reduction!

Just think about how this thing will go around corners... With the standard R8's perfect stability and corneringspeed, and now with over 250 kg's less. Amazing...

:R8:

More POWER
More STYLE
More PASSIONThe 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 (http://www.audizine.com/news/news.php?nid=96&npid=113#). 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 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 580 hp / 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 (http://www.audizine.com/news/news.php?nid=96&npid=113#) 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 (http://www.audizine.com/news/news.php?nid=96&npid=113#). 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 behavior of the front-axle with the rear axle (http://www.audizine.com/news/news.php?nid=96&npid=113#), 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 (http://www.audizine.com/news/news.php?nid=96&npid=113#) allow for additional motor bay and exhaust cooling that, in conjunction with the Carbon Fibre rear diffuser, optimizes 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 MAG11 forged PPI wheels. At the front, 10Jx19 MAG11 wheels with 255/35 ZR 19 Michelin Pilot Sport 2 tyres are fitted and an impressive 11.5J x 20 MAG11 wheels with 325/25 ZR 20 Michelin Pilot Sport 2 tires 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-colored brake callipers. 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.

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 millimeters 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-colored 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 (http://www.audizine.com/news/news.php?nid=96&npid=113#). Highlighting the exclusivity of this limited series production is PPI RAZOR GTR badging, threshold plates, and an aluminum production plaque framed by Carbon Fibre.
