Audi TDI research for Le Mans implemented in road cars

Audi’s efforts with the R18 e-tron quattro and its predecessors were not limited to creating the best car for Le Mans as many of the TDI research conducted has found its way in the company’s road-going models. At this year’s race, Audi managed an excellent one-two win with a couple of R18 e-tron quattro hybrid prototypes that covered no less than 6,300 miles and obtained the eight victory for Audi TDI Power.

Le Mans has been used by Audi as a test laboratory for shaping up future road-going cars for several years now and the findings in TDI development as well as lightweight construction and aerodynamics have influenced road-legal cars such as the A4, A5 and A6 TDI ultra models which provide great fuel efficiency without having a negative effect on the car’s performances.

The above mentioned ultra models can return as much as 67.3 mpg UK in the combined cycle with CO2 emissions as low as 109 g/km. These figures are possible thanks to the advancements made by Audi in TDI research and will likely be implemented across more models in the following period.

Audi has also made improvements in the headlight technology with the introduction of matrix LED lights in last year’s R18 e-tron quattro that have found their way onto a road-going car, the limited-run R8 LMX.
