The new Brabham racing car will be put through its paces at The Bend Motorsport Park in Tailem Bend, South Australia, with the car officially launched in Australia on Tuesday night.

The Brabham BT62, which was unveiled at Australia House in London on May 3, was spotted at The Bend nearly a week ago by car enthusiasts in its new livery.

The 7.77-kilometre Tailem Bend track has now been named as the official Australian testing facility for the car.

David Brabham, who tested the car at the new circuit, said The Bend was a world-class circuit and a testament to the race circuit's owner, Adelaide businessman Sam Shahin.

"The track gives the car and the driver a great workout and we look forward to working with The Bend team as our testing programme continues," Mr Brabham said in a statement.

Dr Shahin said he was proud to partner with Brabham Automotive on its testing programme for the BT62.

The cars will be built at the ZF Lemforder facility in Edinburgh Parks in Adelaide's northern suburbs in the shadow of the former General Motors Holden automotive plant.

The company has said the build would be limited to 70 cars to mark the years since Sir Jack Brabham launched his racing career.

Brabham Automotive's commercial director, Dan Marks, said the company had chosen South Australia due to its "rich automotive heritage".

"Adelaide, in particular, is a centre of excellence for engineering capability and capacity," he said.

"When you consider Adelaide's famed motorsport connections, there is simply no better place for us to be manufacturing high-performance cars."

Business SA chief executive Nigel McBride said ZF Lemforder, and its associated investment group Fusion Capital, wanted a 400-bus contract from the State Government to underpin its Brabham investment.

"The critical mass of the bus contract would underpin Fusion's plans for the Brabham supercars and allow other niche projects, including electric vehicles, to become a reality here," he said.

The first cars are expected to be delivered in late 2018.
