INDYCAR announced numerous safety enhancements for the upcoming 2016 season on Tuesday. These additions include tethering of aerodynamic components and other parts on the cars to improve the overall safety of the driver behind the wheel.
INDYCAR will use high-tensile Zylon tethers that will decrease the possibility of objects becoming detached during an accident on the track. Teams will be required to tether all rear beam wings, rear wheel guards and the nose of the car at tracks greater than 1.5 miles in length. In addition, Dallara has also designed a new tethering system designed specifically for tracks like Texas, Indianapolis and Pocono.
“It is a continual goal to improve safety for all the participants, fans and drivers alike,” said Will Phillips, INDYCAR vice president of technology, in a release. “We also need to do this in a fashion that does not create more yellow-flag racing and try to prevent as much debris as possible. We have great support from our partners to improve safety and wish to thank Chevrolet, Honda and Dallara for their participation and efforts in working together to implement change.”
INDYCAR also made other changes that will further increase the safety of the cars.
- A domed skid plate on the underside of the chassis, which improves its yaw/spin characteristics, will complement rear wing flaps that deploy at 90 degrees if a car spins and travels backward on a superspeedway. The package will minimize the incidence of the car becoming airborne. The rear wing flaps have been tested in wind tunnels at General Motors and Texas A&M University. Components are scheduled to be available for the April 6 test on the 2.5-mile Indianapolis Motor Speedway oval.
- An update to the Engine Control Unit (ECU) prevents a car from moving forward during a pit stop if the gearbox is not in neutral while the fuel hose is attached. Through the ECU, the fuel probe activation sensor can stop the car from moving forward by returning the engine to idle and engaging the clutch if the car is not in neutral when the fuel probe is plugged in.
- Another ECU update puts the engine in idle faster if too much pressure is applied to the throttle or brake pedal. The throttle pedal failsafe will engage and idle the engine when pressure applied to either the throttle or brake pedal exceeds a calibrated threshold.
All of these safety additions come after Justin Wilson lost his life in a crash at the Pocono Raceway in August. Wilson was racing along when Sage Karam’s car broke loose nose-first into the outside retaining wall. The nose came loose into the air and hit the helmet Wilson was wearing. The incident took place with 21 laps to go.
