IRL announces rules changes for 2007 The 2007 Drive for Diversity class was unveiled Monday, a seven-driver group that will compete in both the NASCAR Grand National Division and NASCAR Whelen All-American Series.
In addition to its switch to 100 percent fuel-grade ethanol, a motorsports first, IndyCar Series officials announced several technical and administrative changes to the rules that will govern the 2007 IndyCar Series season.
“Though they are not dramatic, the changes made for 2007 are necessary as our drivers and teams face the most diverse schedule in racing,” said Les Mactaggart, senior technical director for the Indy Racing League, sanctioning body for the IndyCar Series. “The changes will enhance an already extremely competitive race product.”
Several technical changes have been made in an effort to further contain costs and increase the safety of IndyCar Series cars.
The changes include: An increase in the displacement of the Honda Indy V-8 engine to 3.5 liters, which will increase low-end torque for short ovals and road courses. A reduction in the capacity of the fuel cell to 22 gallons, to correspond with improved fuel mileage associated with the change to 100 percent fuel-grade ethanol. The addition of a rear-mounted safety light for all events. The light, which will be mounted on the attenuator, will function as a safety light on at all events and will be controlled by race control. It will additionally serve a rain light on road courses. On short ovals and road courses, IndyCar Series teams may use any wing angle on the front wing main plane between negative five (-5) and five (+5) degrees. In addition, several administrative changes have been made to race event weekends. They include: Final practice sessions have been eliminated at all oval events but in order to maintain on-track time pre-qualifying sessions have been extended by 15 minutes. If qualifications are cancelled, IndyCar Series officials will set the starting lineup by entrant points. IndyCar Series officials, in their discretion, will determine the rookie status of any driver. Drivers who have been rookies in prior seasons may maintain retain rookie status independent of number of races started.
