It is the first team to fully commit to Formula A which is designed similar to a Formula Libre-style class.
Gilmour, a double outright and multiple national class Australian Formula 3 champion operation, will field 16-year-old West Australian Calan Williams after he tested a Dallara F307 at Queensland Raceway late last year.
The team is yet to confirm who will handle its second Dallara F311, which won the Formula 3 Championship for Jon Collins.
“We are thrilled to welcome Gilmour Racing to the Formula A Australia presented by Kumho Tyre series,” Formula A manager Liam Curkpatrick said.
“Errol Gilmour has built an extremely successful team that has become one of the most professional in the sport and their track record is outstanding.
“Calan Williams is a terrific young talent and we are sure that he is going to make an immediate impact on the scene this year driving for Gilmour Racing.”
Formula A organisers have reportedly received strong interest from competitors looking to race ‘wings and slicks’ cars outside of the Formula 3 regulars.
These include interest for USF2000 and Formula 1000 cars which are eligible to compete in the series under the multi-class structure.
The first of the non-F3 cars are expected to be announced in the near future.
