The car was fitted with a 6.0-litre V12 engine, utilising Volkswagen Group's long-established Turbocharged Direct Injection (TDI) turbodiesel technology. This engine produced {{convert|368|kW|PS bhp|0|lk=on}} at 4,000 and {{convert|1000|Nm|0|lk=on}} of torque at 1,750-3,000 rpm. The car utilises Audi's quattro permanent four-wheel drive system and a 6-speed manual transmission. The car accelerates from {{convert|0-100|km/h|0}} in 4.2 seconds, and can attain a top speed of over {{convert|186.41|mph|km/h|1|abbr=on}}.[4] The R8 TDI Le Mans has modified suspension settings and brakes to cope with the additional power and weight ({{convert|300|kg|1|abbr=on}}), resulting from replacing the standard V8 engine with the V12 TDI. The V12 TDI requires more cooling than the standard R8, hence a NACA duct is incorporated in the roof to feed additional air into the engine. The vents on the front and back of the car have also been increased by 20% in size. The car all-LED headlamps which were first seen on the Audi Le Mans Quattro concept. For its appearance at the Detroit Motor Show, Audi fitted 20 inch alloy wheels. The rear bulkhead has been moved forward in order to accommodate the physically larger V12 engine, meaning it loses the space behind the rear seats usually found on the standard R8. In May 2009, Audi decided to halt plans for possible production of the R8 TDI, citing "the cost of re-engineering the petrol R8 to accommodate the massive twin-turbocharged diesel engine is simply too great – and that it would be unable to recoup its investment through sales alone".[5] References1. ^{{cite web|url=http://www.audi.co.uk/audi/uk/en2/experience/Studies/Audi_R8_TDI_Le_Mans.html|title=Audi R8 TDI Le Mans|work=www.audi.co.uk}} 2. ^{{cite web|url=http://www.autoexpress.co.uk/news/autoexpressnews/214614/audi_r8.html|title=Diesel power for Audi R8 supercar|work=www.autoexpress.co.uk}} 3. ^{{cite web|url=http://www.edmunds.com/insideline/do/News/articleId=124210 |title=2008 Detroit Auto Show Preview: Audi R8 TDI Concept |work=edmunds.com |deadurl=yes |archiveurl=https://web.archive.org/web/20080617201703/http://www.edmunds.com/insideline/do/News/articleId%3D124210 |archivedate=2008-06-17 |df= }} 4. ^{{cite web|url=https://www.autoblog.com/2008/03/03/red-menace-audi-r8-tdi-le-mans-infiltrates-geneva/|title=Red Menace Audi R8 TDI Le Mans Infiltrates Geneva|publisher= Autoblog|author= Alex Nunez|date=3 March 2008|accessdate= 1 April 2018}} 5. ^{{cite web|url=http://www.audisite.com/532/audi-cans-the-r8-v12-tdi/|title=Audi Cans the R8 V12 TDI|work=audisite.com}} External links{{Audi}} 5 : Audi concept vehicles|Coupés|Sports cars|Rear mid-engine, all-wheel-drive vehicles|Cars introduced in 2008 |
