Audi R8 LMS competing in the 2009 Belgian GT Championship seasonFor 2009, Audi announced the production of an R8 LMS racing car, designed for the GT3 rules in the FIA GT3 European Championship and various national racing series. Known within Audi Sport as the 'R16', the R8 LMS features a 500 PS (370 kW; 490 bhp) V10 engine.
Because the GT3 regulations prohibit the use of four-wheel drive, Audi had to drop its 'trademark' quattro four-wheel drive system, and the R8 LMS comes with the typical rear-wheel drive setup. The torque is transmitted via a newly developed six-speed sequential sports gearbox.
Despite the development of the car, Audi itself had stated not to enter any races with the new GT3 car as an official 'factory' team.
The car was unveiled at Essen Motor Show. The first Audi R8 LMS (chassis number 101) was delivered to Audi Sport Italia in 2009.
In the 24h Nürburgring, and preceding VLN endurance racs, Audi privateer teams had entered four cars, operated by the Abt Sportsline and Nürburging-based Phoenix race teams. Until the 19th hour, two of these R8 remained challengers for the lead, against two Manthey-operated Porsche GT3 in the same lap, before the leading #99 car suffered suspension problems. The #97 finished 2nd, and despite electrical and gearbox problems, the other two cars finished 23rd or better.

Reviews

Many publications[which?] were hailing it as the first car to truly be able to beat the Porsche 997 — considered by many[who?] to be one of the best sports cars ever made, and a leader in its class.
Initial comparison tests have proven quite positive in this respect; Evo Magazine listed it as a "supercar", compared the R8 to the Porsche 911 Carrera 4S, Aston Martin V8 Vantage, and BMW M6 and after praising the R8's "amazing stability, traction and grip, unparalleled steering accuracy and bite, (and) its uncannily flat and disturbance-free ride", claimed that as a result of "the sublime effortlessness of it all", the Audi is a better sports car. The article concluded that "Audi humbles Porsche. A new dawn starts today".
Other publications have also written similar reviews of the Audi beating the Porsche in comparison tests. In a drag race between the R8 and a 997 Carrera S, the Porsche won just crossing the line a half meter before the R8.
The television show Top Gear compared the Nissan GT-R to the R8, and remarked that the R8 was "simultaneously less impressive and yet somehow more involving". On the R8 they wrote that "it rewards driver input", calling it "fantastic in a way that will appeal more to true car enthusiasts", but also remarked that it was "much slower", and the GT-R was cheaper. On their test track, the car performed better than a Lamborghini Gallardo and an Aston Martin DB9.
On Bedford Autodrome, tested by Evo Magazine, the R8 was faster than the Lamborghini Gallardo.


V10 engine

Audi AG unveiled the Audi R8 V10 on 9 December 2008. It uses a 5.2 litre FSI internal combustion engine, based on the unit in the Lamborghini Gallardo LP560-4, but is detuned to produce a motive power output of 386 kilowatts (525 PS; 518 bhp), and generate 530 newton metres (391 ft•lbf) of torque.[3] Compared to the V8 variant, the R8 V10's performance numbers are enhanced. Audi estimates the new 0-100 kilometres per hour (62 mph) time as only 3.9 seconds, 60-124 mph in 8.1 seconds, and a top speed of 196 mph (315.4 km/h). Other changes to the V10 version of the R8 include some aesthetic differences such as all-LED headlights, interior enhancements, and a more aggressive body styling, larger rear brakes and unique roadwheels.
It was initially thought that this version of the R8 was going to have the same engine as the C6 Audi RS6, a 5.0 litre V10 TFSI 'biturbo' engine, which produces 580 PS (427 kW; 572 bhp). However, some components of the twin-turbo system overheated, and one prototype was destroyed by fire at the Nürburgring. This model is showing at the 2009 North American International Auto Show. This version of the R8 appears in the trailers and in the box art of the upcoming Xbox 360 racing game, Forza Motorsport 3.

Powertrain

Powertrain

The Audi R8 was initially equipped with a 4.2 litre V8 internal combustion engine. Specific detail: 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 cc (254.0 cu in). It develops a motive power output of 309 kilowatts (420 PS; 414 bhp), 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 B7 Audi RS4, but is modified to use dry sump lubrication system. This V8 is a highly reworked, high-revving variant from 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 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.
A new additional variant with a 5.2 litre Fuel Stratified Injection (FSI) V10 engine was added on the 9th of December 2008, which produces 386 kW (525 PS; 518 bhp) and 530 N•m (391 ft•lbf).
The transmission options are either a Lamborghini sourced manual gearbox with metal gate for the shift lever, or an Audi-developed "R tronic" gearbox - which is a single-clutch semi-automatic electrohydraulic manual transmission, without a traditional clutch pedal. 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 December 2008).

Production

PRODUCTION

To produce the R8 at quattro GmbH, seventy workers fit 5,000 unique parts by hand. The factory at Neckarsulm, redeveloped at a cost of €28 million, produces between eight and fifteen cars a day. Ninety-five lasers inspect the entire car in five seconds to ensure that over 220 measurements are within 0.1 millimetres of the programmed plans.

AVAILABLE MARKET
The 2-seat coupé is currently available in Europe, the United States, Canada, Australia and Japan. Rumours hold that an R8 Spider, an open-top roadster model, will follow sometime in 2009.
In Latin America, the R8 became available at the end of 2008 at dealers in Mexico City, Bogota, Medellin, São Paulo, Rio de Janeiro, Buenos Aires, Lima and Santiago. Customers bought every unit available for 2008 within a week after the R8 premiered at the Bogota International Auto Show and Auto Expo of Medellin.
In Asia, the R8 is available in India, Japan, Taiwan, South Korea, Philippines and Hong Kong, and has been available in China, Turkey, United Arab Emirates, Singapore and Indonesia since 2008.
