What tracks are not returning to IMSA in 2023?
Two tracks drop away from the calendar, Detroit and Mid-Ohio. The latter has been on the calendar since 2018, as well as being a stalwart of sportscar racing in IMSA’s former life, and its rollercoaster of a lap has been a welcome addition. Sadly IMSA has now deemed that its facilities are no longer good enough to host a round.
Detroit’s departure is a little more nuanced. That round is a partnership with the IndyCar Championship, and that race will switch from The Raceway on Belle Isle in order to move back into downtown Detroit. While this is understood to have played a part, the bigger issue facing IMSA is that the round is on the same weekend as the Le Mans 24 Hours test day. This hasn’t been ideal in the past, but with a huge number of LMDh cars now looking to participate in both IMSA and Le Mans, it became difficult to clash.
