McLaren F1 driver Norris confirmed for Austin IndyCar Esports race

Norris will drive the fourth Arrow McLaren SP entry, the #04 IndyCar Provisional car, while Mostert will be taking over the #98 Andretti Herta Autosport entry from Marco Andretti.

Andretti took part in the Michigan and Motegi rounds, but missed the two road courses that opened the season, at Watkins Glen and Barber Motorsports Park, where his car was driven by Scott Speed.

Mostert joins fellow Supercars driver Scott McLaughlin on the grid for the Austin race.

For the first time, the IndyCar-sanctioned Esports series will not feature a NASCAR star.

Jimmie Johnson competed in the first two events, while Dale Earnhardt Jr raced at Michigan and Kyle Busch ran Motegi.

2015 Indy Lights champion and former Ed Carpenter Racing driver Spencer Pigot, who signed a part-time deal with Rahal Letterman Lanigan affiliate Citrone/Buhl Autosport for 2020 - will also be making his series debut.

That makes it three RLLR-affiliated cars in the field, as for only the second time Takuma Sato will join full-time teammate Graham Rahal on the grid.

The Austin race will feature all the winners so far in this Esports championship: Sage Karam of Dreyer & Reinbold Racing, who won the opener at Watkins Glen, will line up against Barber winner McLaughlin and reigning Indy 500 winner Simon Pagenaud - who was the victor at both Michigan and Motegi.

The race will run to 32 laps, and is expected to be a one-stop race due to a competition caution period on scheduled for lap 12.

This is a feature carried over from the second round on the road course at Barber, which bunched the field and intensified the wheel-to-wheel action.

On that occasion, however, McLaughlin made two stops - a move crucial to his defeat of teammate Will Power.

The race at the virtual 3.427-mile COTA begins at 7.30 BST on Saturday and will be televised live on NBCSN.
