IndyCar's Detroit Grand Prix: A Downtown Return with Split Pitlane and Trans Am TA2.

IndyCar returns to a downtown street circuit in Detroit, replacing the Belle Isle venue on the calendar. The track is 1.7 miles long and features a split pitlane, with half the field pitting on the left and half on the right. The event is supported heavily by Penske Entertainment and promises to be one of the most fan-friendly events of the year, with more than half of the circuit open to the public free of charge. The track is similar to the Detroit Grand Prix Formula 1 layout of the 1980s, with tight corners and a long straight where cars will reach around 190mph.
