Unveiled at Top Marques Monaco this year the PPI Razor GTR-10 Limited edition is the latest project from PPI Automotive Design. The improvements are two sided, on one hand 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 and secondly improving the looks of the vehicle inside as well as the outside.
The result is a normally aspirated V10 engine with over 601hp (448kW) at 7,400rpm, and a maximum torque of 565Nm at 6,400rpm at its disposal. Couple the power increase with a weight decrease of 250kg over its serial counterpart (serial curb weight V10 R-tronic: 1,625kg). The end result is the ability to achieve speeds from 0 to 100km/h (62mph) in a mere 3.2 seconds (with modified R-tronic Gearbox) and a maximum top speed of 335km/h.
On the aerodynamic side of the story PPI offers a kit reducing the weight of the car by using loads of carbon fiber. The body kit includes a new front bumper replaces the serial bumper, larger air inlets in connection with a new incorporated LED day-running unit, sideskirts with inlets aiding much needed cooling to the engine oil coolers and rear brake system. Like the rest of the supercar the roof pillars and doors are draped in carbon fiber as well.
The carbon fiber rear wing has an adjustable gurney-flap. The motor cover is made of carbon fiber and incorporates glass made of the light polycarbonate material Makrolon. The engine lid also has specially designed carbon fiber ram-charged air inlets. 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, optimises the airflow over and through the rear portion.
The GTR-10 utilizes lightweight MAG11 Forged Aluminium PPI wheels. At the front, 9Jx19 MAG11 wheels weighing 10.0kg with 245/35 ZR 19 Michelin Pilot Sport 2 tyres are fitted and a 12.0J x 20 MAG11 wheels weighing 10.9kg with 325/25 ZR 20 Michelin Pilot Sport 2 tyres are used at the rear. PPI has also developed a special high-performance braking system available for the Razor GTR-10 that can be identified by its metallic orange-coloured brake callipers.
The height of the car is adjusted with KW Automotive springs and an hydraulic lift system for the front axle, which can increase ground clearance by up to 45 millimetres if needed.
The interior got an upgrade as well. The serial interior is replaced by Onyx Nubuck-leather with Metallic-coloured accents and highlights per clients request. PPI equips the limited edition with 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 fiber 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).
Additionally there are the Razor GTR-10 badging, threshold plates, and an aluminium production plaque framed by carbon fiber.
