RUF RGT-8 (2011)

[dosvidosov]

Очень интересен данный автомобиль. Вкратце - это 997 с двигателем V8 собственной разработки и, почему-то, салоном от Каймана

С сайта РУФ (http://www.ruf-automobile.de/en/RUF-RGT-8.04a2e.php):

Almost 10 years ago to the day, RUF began to fill niches in the market with the, at that time new, water-cooled Porsche models. The first RUF RGT was based on the Porsche 996. It used the 3.6 litre engine from the GT3 as the base with the crankcase from the air-cooled 3.6 litre engines. The engine delivered 385 HP (283kW). The car itself ran on 18" RUF alloy wheels and the narrow body was optimized aerodynamically. The vehicle was fitted with our discrete but functional Integrated Roll Cage.

In 2004 the story continued, this time based on the Porsche 997. Immediately recognizable by the carbon composite fender extensions both front and rear. The powerplant was a naturally aspirated 3.8 litre unit delivering 445 HP (327kW). A dry-sump oil system ensured sufficient lubrication even under tough racing conditions. A roll-cage was fitted standard ensuring a high level of passive safety. The RGT was supplied with a chassis optimized for the race track and ran on 19" alloy wheels.

March 2010 and the time is right for RUF to announce the next generation of RGT, the RGT-8. This spectacular prototype vehicle is powered by a completely new RUF-designed V-8 engine with a 180° crankshaft “Flatcrank”. Four valves arranged spherically together with multipoint fuel injection ensure optimal mixture conditions while the dry-sump system supplies the necessary lubrication. The lightweight engine has a very compact design, has a capacity of 4.5 litres arranged as a V-8 and delivers 550 HP (404 kW) at 8500 rpm and complements with a maximum torque of 369 lbs.ft (500 Nm) at 5400 rpm. At all stages of the design process, compactness and weight saving were of priority, the result of which is a total engine weight of less than 200 kg. A 6-speed gearbox with shortened gear shift movement transfers the power to the rear axle. To ensure the best adhesion characteristics, the RGT-8 is supplied with Michelin Pilot Sport Cup tires running on 19" RUF forged alloy wheels utilizing a single central retaining nut. The powertrain is rounded off with sturdy ceramic brakes as standard for optimal braking.


The current Porsche 911 forms the basis for the RGT-8 chassis which is then further optimized with bodywork components from RUF. As always, an Integrated Roll Cage is supplied delivering increased chassis stability and passive safety. In addition, we are pleased to offer a Frère Package which enhances the standard vehicle with special front fenders, nose and dashboard components. The styling was inspired by the 550 Coupé with which Paul Frère, the Belgian race driver, won the best of class at the 24 Hours of Le Mans in 1953.

RUF RGT-8 production start is planned for 2012.
