INDYCAR confirms additional car tethers among other 2016 safety enhancements

INDYCAR has outlined the formal safety enhancements it plans to do to the base Dallara DW12 chassis for the 2016 Verizon IndyCar Series season.

The full release from INDYCAR is below:

Tethering aerodynamic components of the Dallara IR-12 chassis is among safety enhancements announced by INDYCAR that will be implemented for the 2016 Verizon IndyCar Series season.

The high-tensile Zylon tethers minimize the possibility of components becoming detached from the race cars during accidents.

The rear beam wing and rear wheel guards will be tethered for all Verizon IndyCar Series events and the car’s nose will be tethered on superspeedway ovals (1.5 miles or longer). Dallara also has designed a tethering system for the front wing main plane for the three superspeedways on the 2016 schedule – Indianapolis Motor Speedway, Texas Motor Speedway and Pocono Raceway.

Since 1999, Verizon IndyCar Series cars have employed wheel restraints attached to the chassis and suspension. The Suspension Wheel/Wing Energy Management System (SWEMS) also includes one or two restraints attached from the rear wing main plane to a secure location on the transmission.

“It is a continual goal to improve safety for all the participants, fans and drivers alike,” said Will Phillips, INDYCAR Vice President of Technology. “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.”

Other changes for the 2016 season as part of INDYCAR’s ongoing research and development to improve the on-track product and safety include:

  • 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.

The Extreme E team formed by Andretti Autosport and United Autosports named Catie Munnings and Timmy Hansen as its drivers Monday for the series’ inaugural 2021 season.

Munnings is a successful veteran of rally series. Hansen is a past winner and champion in the World Rallycross Championship.

They both will race in the environmentally conscious electric SUV series that will hold events in five areas around the world that are threatened by climate change. Chip Ganassi Racing and six-time Formula One champion Lewis Hamilton also are fielding cars in Extreme E, which will feature male and female co-drivers on every team.

Catie Munnings

“I’m so excited to join Andretti United Extreme E,” Munnings said in a release. ““I was really intrigued when I first heard about Extreme E, I just knew I had to be involved. The male / female racing partnership is a fantastic and exciting new concept. The season has incredible locations and the racing will be very exciting. It will be a new challenge for the teams and drivers, and I’m so thrilled to be working with such a strong team.

“The championship is a really innovative concept, it’s combining motorsport and science and will produce an important legacy in each race location. Bringing the platform that motorsport has in line with the awareness that the planet needs right now is awesome and a really important message.”

Timmy Hansen

Said Hansen: “Going into the Extreme E will be a new chapter in my career, one that I am extremely excited about. It is something brand new, not only for me, but the whole of motorsport. The format is something

we’ve never seen before. I’m also delighted to be able to carry the message of something bigger – talking about the environment and doing something good for the world – that’s something that really drives me. It’s going to be a big adventure in life to see these locations and I’m going to do my best in carrying this responsibility and hopefully making people aware of the challenges we have in the world, together with our passion for racing.”
