The IndyCar Series and longtime chassis manufacturer Dallara have agreed to new multiyear contract that will extend their relationship though at least 2020 season.
Series officials made the announcement Thursday at the North American International Auto Show in Detroit. Terms were not disclosed.
Dallara will continue providing driver safety cells in 2018 when new cars are expected to be used. Series officials also provided sketches of what the new aero kits may look like. Early designs appear to provide more head protection for drivers.
Jay Frye, the series' president of competition and operations, said Dallara's safety record gives drivers "a great deal of confidence."
The Italian company has its American headquarters in Speedway, not far from the famed Indianapolis Motor Speedway and IndyCar headquarters.
"Dallara’s continued participation in our sport provides IndyCar and our competitors a tremendous amount of confidence,” said Jay Frye, IndyCar president of competition and operations, in a written statement. “Dallara has been an instrumental partner in the Verizon IndyCar Series for 20 years and we are excited to extend our relationship with them."
