Audi R8 4.2 FSI V8 - 2006

Marca - Kyosho
Escala - 1:18
The Audi R8 (Typ 42) is a mid-engine sports car, which uses Audi's trademark quattro permanent all-wheel drive system. It was introduced by the German automaker Audi AG in 2006.
The car was exclusively designed, developed, and manufactured by Audi AG's high performance private subsidiary company, quattro GmbH, and is based on the Lamborghini Gallardo platform. The fundamental construction of the R8 is based on the Audi Space Frame, and uses an aluminium monocoque which is built around space frame principles. The car is built by quattro GmbH in a newly renovated factory at Audi's 'aluminium site' at Neckarsulm in Germany.
In 2005, Audi announced that the name of the successful Audi R8 race car would be used for a new road car in 2007, the Audi R8, based on the Audi Le Mans quattro concept car, appearing at the 2003 International Geneva Motor Show, and 2003 Frankfurt International Motor Show. The R8 road car was officially launched at the Paris Auto Show on 30 September 2006. There was some confusion with the name, which the car shares with the 24 Hours of Le Mans winning R8 Le Mans Prototype (LMP). 6-time 24 Hours of Le Mans winner Jacky Ickx described the R8 as "the best handling road car today". The Audi R8 is used as a safety car in Deutsche Tourenwagen Masters and British Superbike Championship racing series.
The R8 is due to be replaced with a brand new model in calendar year 2014. The highest output version of Audi's new 4.0 liter V8 twin-turbocharged engine is expected to power the new car. This engine is scheduled to be previewed as a detuned version in the 2012 Audi S8- with 518 hp (386 kW) on tap. In the R8 application it is expected to produce about 600 hp. Combined with an approximate 200 lb (91 kg) weight loss, the new R8 is expected to compete well with the new Porsche 991 twin turbo model and will likely perform significantly better than the current R8 GT with a 0-60 mph time in 3.2 seconds and a quarter mile in less than 11 seconds. A dual clutch automated gearbox will be offered for the first time.
The Audi R8 was initially equipped with a 4.2 litre V8 engine. Specifically, it is an all-aluminium alloy 32-valve (four valves per cylinder) petrol engine, utilising Fuel Stratified Injection (FSI), and has a displacement of 4,163 cubic centimetres (254.0 cu in). It develops a motive power output of 420 metric horsepower (309 kW; 414 bhp) (Directive 80/1269/EEC), and generates 430 newton metres (317 ft·lbf) of torque, on 98 RON 'Super Unleaded' petrol. It is basically the same engine used in the Audi B7 RS4, but is modified to use dry sump lubrication system. This V8 is a highly reworked, high-revving variant of the existing 4.2 litre V8, but includes cylinder-direct fuel injection (Fuel Stratified Injection), and four valves per cylinder, instead of five (as used on the previous non-FSI variants). It also uses two chain-driven double overhead camshafts (DOHC) per cylinder bank, and utilises variable valve timing for both inlet and exhaust camshafts.
The transmission options are either a Lamborghini sourced six-speed manual gearbox with metal gate for the shift lever, or an Audi-developed R tronic gearbox - which is a semi-automatic, without a traditional clutch pedal with automatic gears shifting mode. These options are the same as those available on the Lamborghini Gallardo. A double clutch Direct-Shift Gearbox (DSG), now badged by Audi as S tronic, is not available (as of April 2010).
