Detroit IndyCar organisers promise track improvements for next year

A new 1.645-mile track was constructed in the shadow of the Renaissance Center, the global headquarters of General Motors, and used some stretches of the Formula 1 track, which was used from 1982 to 1988.

Penske Corporation’s president Bud Denker was the mastermind of the project, inspired by IndyCar’s successful event on the streets of Nashville.
