Audi’s diesel show-off
Audi revealed its new concept of diesel engines with greener emission. In order to achieve staggering performance of 0-100 in 4.2 seconds and top speed more than 186 mph, Audi developed new V12 twin turbo 500 horsepower engine (plus 737 lb-ft of torque). Concept car is called R8 TDI and based on R8 with petrol V8.
R8 TDI is green enough to suit new California’s tough standards, and low emission is achieved by fitting five fuel injection events per engine cycle plus new three stage exhaust. Standard catalyst and particle filter is fitted, as well as additional catalyst with AdBlue additive to break up nitric oxides.
Car is also fitted with quarto all-wheel drive and economy is 24mpg, what is not that bad for supercar of this performance. As whole concept is based on current production R8 model, we may see this concept on sale soon, but in very limited quantity. Still this is good showoff of Audi’s diesel technology and we may expect hybrid diesel-electric car to come next.
