The publication Race Engine Technology has given Audi Motorsport the “Race Engine of the Year” award for their 3.7L V6 TDI powerplant. The engine, which was vital to Audi capturing its 10th title at the 24 Hours of Le Mans last year, produces more than 540-hp through the use of a single turbocharger.
Compared to its V10 TDI predecessor, the 120-degree, extremely compact V6 TDI is 25-percent lighter and uses a single turbo rather than the twin-turbo the V10 TDI used. The single turbocharger sits above the engine and draws its air directly through the roof-mounted air scoop. The setup was the result of a collaboration with Garrett, one of the leading manufacturers of turbochargers.
“Audi invented the TDI engine and is convinced that this technology remains one of the most efficient and modern forms to power a car – especially at Le Mans where engines with high specific power, low fuel consumption and low emissions are a necessity,” explained Audi Motorsport’s Dr. Wolfgang Ullrich.
