Refinements to the 2016 Verizon IndyCar Series rulebook, distributed to teams and suppliers Dec. 19, clarify procedures established by INDYCAR in the past two seasons and highlight ongoing efforts to improve the overall fan experience in the upcoming season. Areas of interest in the rulebook include the following:
INDYCAR has also established in the rulebook the aerodynamic bodywork parameters for each of the five ovals on the 2016 Verizon IndyCar Series schedule. The aero specifications for each oval include:
Phoenix International Raceway, which will see a 2016 return of Indy car racing for the first time in 11 years, will run the same aero configuration as used at Iowa Speedway in 2015;
Indianapolis Motor Speedway and Pocono Raceway will run the same aero configuration as in 2015, with the addition of rear wheel guard infills that were implemented at Texas Motor Speedway in 2015, as well as a domed skid plate underneath the car and rear wing beam flaps. The skid plate and beam flaps were announced Nov. 24 as part of INDYCARs continuously evolving safety enhancements.
Texas Motor Speedways aero configuration, which included the rear wheel guard infills in 2015, will add the domed skid plate and rear wing beam flaps in 2016, plus see a slight increase in available downforce.
Iowa Speedway will see a slight reduction in available downforce due to a reduction in rear wing angle.
Indianapolis 500 Qualifying
Under the updated regulations, the provisional field of 33 cars for the 100th Running of the Indianapolis 500 will be set on the first day of qualifications at the Indianapolis Motor Speedway oval on May 21, 2016. This means that any traditional bumping of cars from the field of 33 will take place on the first day of qualifying.
Procedures for the second day of 2016 qualifying, scheduled for May 22, will see race starting positions among the 33 provisional qualifiers finalized.
