Before it had been revealed, the Brabham BT62 remained a total mystery to anyone not involved in its development.

Despite being built in Adelaide and tested on Aussie tracks including Phillip Island, it had been so well-guarded that locals were stunned to discover this car had been built right under their noses.

But now, a few weeks after its reveal, we’ve been drip fed small amounts of official information from Brabham.

Thanks to an Adelaide-based photographer (@apex___media on Instagram), we’ve also now seen imagery and footage of it in action at The Bend Motorsport Park.

It’s the first time we’ve seen one in white, and it gives a much clearer view of its aerodynamic features than the green and gold launch car does.

Managing director of the Brabham brand (and son of Sir Jack) David Brabham was present for the test day, though the company itself is remaining hush on what it’s testing for, or attempting to achieve.

There’s also no confirmed lap time for the BT62 at The Bend’s circuit, though we know the company says it has “eclipsed the official outright lap record at Phillip Island.”

The naturally-aspirated V8-powered track-only car produces 522kW and 667Nm, and weighs only 972kg dry. This equates to 537kW per tonne, and is complemented by more than 1200kg of downforce.

A highlight of its engine is its sound, which is clearly audible in the short video provided by the photographer who captured these images of the car testing.

We expect more official information from Brabham to be revealed in the coming weeks. Stay tuned.
