The story

The Brabham BT62 stands as a testament to engineering excellence without the budgets of the big manufacturers. Paying homage to the legendary Brabham name while setting new benchmarks in modern track cars, the BT62 was designed and built by Brabham Automotive as a track-focused hypercar combining innovative design, the latest technology and a relentless pursuit of performance.

The BT62 has an ultra-lightweight carbon fibre body and a lightweight tubular chassis, so the car weighs just 972 kg. It is powered by a 5.4-litre naturally aspirated Ford-derived V8, tuned by Brabham to 700 horsepower and 667 Nm of torque. Advanced aerodynamics generate over 1,200 kg of downforce.

What happened

01

SB Race Engineering and the BT62

As supercar and motorsport specialists we played a pivotal role in preparing the first customer BT62 for competitive racing. The car, owned by long-time SBR client Paul Bailey, arrived with us in late 2020 and work began for the 2021 season.

Our involvement began with comprehensive testing and calibration to optimise the car as a race car. We fine-tuned the suspension, brakes, engine management and traction control to suit our customer and the intended racing environment. There were many changes needed, as the BT62 was not built to any homologation standard and was really a track day car; our attention to detail saw a complete strip and rebuild to make it suitable for racing.

We also provided trackside assistance and data analysis during the car's initial outings. The collaboration between Brabham Automotive, David Brabham and SB Race Engineering was key in transforming the BT62 into a race-winning machine.

Race-winning performance, but what happened?

After considerable modification we prepared and supported the car in the 2021 and 2022 seasons in the British GT Cup Championship. Drivers Paul Bailey and Ross Wylie racked up race wins, class wins and fastest laps in every race, but we were plagued with engine reliability problems. When the BT62 was on form it was untouchable.

We retired the car and ended SBR's involvement with the Brabham project in May 2022. We assisted with running the car in 2023, though not under the SBR banner, and the continued failures saw it enter one race only. Brabham Automotive lost the contract to build cars bearing the Brabham name that year. Still with persistent engine issues, the BT62 was withdrawn from racing after another brief run in 2024.

We are currently developing the car: it has been testing in 2025 and competed in a few races to monitor reliability. Watch this space.

A legacy reimagined

Despite the problems, the BT62 is more than a hypercar; it is a celebration of a legacy that began with Sir Jack Brabham. With the involvement of specialists like us, the BT62 has proven itself a formidable competitor. We are still immensely proud to have been involved with the BT62 project and its ongoing development in the UK.
