ela2Hampshire-based Brabham Automotive has unveiled exciting features about its racecar – the BT62


With the CFD model honed, new engineering elements were introduced and detail changes made one at a time, working front to rear, to quantify their combined impact on overall performance and cooling. The primary aim was to ensure that every change resulted in all elements working in harmony with the airflow.

The underfloor of the car is completely flat. High air pressure on the under-surface of the car would cause lift. Maintaining low pressure underneath assists in maximising downforce and is critical for vehicle stability at higher speeds. The low-pressure underfloor area contributes to a centre of pressure that works with the car’s static centre of gravity, contributing to the BT62’s dynamics and high-speed stability.

At 300 km per hour, the aero load results in eight millimetre deflection at the front and around 18mm at the rear. The strength-to-weight ratio of materials like carbon-fibre makes the composite material an obvious choice for shedding load on critical parts while maintaining superior strength.

The result of all this is great grip and downforce figures that out-perform other high performance competitors.

According to the company, the BT62 is relatively lightweight and has a combination of elements that work together to sculpt a path through the air. About driving upside-down, it is estimated that with full fluids and driver on board, the BT62 generates enough downforce to drive upside-down at around 265 km per hour.
