The activity going here at VIRginia International Raceway this weekend definitely does not qualify as hyper-miling. In fact it is anything but. The thirty young racers competing in the
TDI cup are hustling their cars around this beautiful 3.27 mile long circuit as fast as they can. But they are still doing it in a relatively thrifty manner. The racing
are putting out 170hp which is enough to average over 87mph here. While most race cars get mileage in the single digits and the national fleet average is 20.2mpg the racers are averaging 25mpg running on regular pump ultra-low sulfur
fuel. That's good enough to go the entire race weekend without filling up. Starting with the next race at Mosport on May 17-18 the cars will start using B5
which is what the production
are certified for. The cars are also running with the same exhaust after-treatment system as the production fifty state legal models. That means every car has a lean NOx trap and diesel particulate filter installed.
