The biggest change to this year’s IndyCar campaign sees the Nashville finale pushed forward by two weeks, moving from its mid-September slot to a late August finish, to land on the US’s Labor Day weekend.

It means all 17 rounds are squeezed into a six-month schedule.

A return trip to The Thermal Club is set for 23 March which will now be a points-paying round after acting as a non-championship race when it debuted in March.

St. Petersburg retains its opener slot on 2 March before The Thermal Club second round on 23 March, with Long Beach hosting round three on 13 April.

A trip to Barber on 4 May is slotted in just before the Indianapolis Grand Prix on 10 May and the Indianapolis 500 on 25 May.

One notable change is that the Gateway round in St Louis is moved up to 15 June.
