Aside from power and technology, aerodynamics are also one of the most important elements of a manufacturer when developing a car. This factor becomes even more important when the car focuses on the track like the McLaren Senna, Ferrari FXX-K or this car, the Brabham GT62.
“Aerodynamic stability is key for any driver who has faith in their car on the track. Whether it’s braking, during cornering, or exiting a corner, if the car is consistent and predictable, the driver can really explore their limits. The BT62 is one of the most stable and predictable cars I’ve ever driven, ”said David Brabham, Sports Director of Brabham Automotive.
As a race car and on the track, the Brabham BT62 is arguably one of the most advanced aerodynamic cars you can buy right now. With its designs, the BT62 can generate up to 1,600 kg of pressure at 300 km / h and especially cornering with 3.5 G of horizontal traction, on par with Formula 1 racing cars. .
Instead of using wind tunnels, Brabham engineers used the Computational Fluid Dynamic (CFD) software to design the exterior and aerodynamics of the car. As a result, learning to have a car that is harmonious in terms of maximum pressure, minimum pullback and still meets the need for heat dissipation for the naturally aspirated V8 engine block of the car.
When passing through the car, the airflow will be compressed by the high pressure elements at the top of the car, then before the other elements divide this compressed air flow through the sides of the car. Lower, the end panels on the front splitter create low-pressure eddies that manage flow along the side of the vehicle, rather than allowing it to run underneath where it would impact the floor and rear diffuser. The underside of the car is completely flat, a key factor in maintaining low pressure. Airflow detail from the front outer vents reveals vortex surfaces that help manage turbulence at the front wheel.
Behind, the spoiler of the car has a pressure / lift ratio of 5: 1, which means that for every 1N of lift, there will be 5N of force pushing down this wing. With this pressure, the body of the car is subjected to a great amount of compression when operating at high speeds. At 300 km / h, the front parts will be subjected to 8 mm ammo at the front and 18 mm at the rear, all distortions due to this pressure will be transmitted to the suspension system so this system. needs to be perfectly tuned. At a speed of about 265 km / h, the car can even adhere to the ceiling due to the effects of pressure.
Brabham BT62 is a supercar developed for racetrack by Australian automaker Brabham. The car uses a naturally aspirated, 5.4-liter V8 engine with a maximum capacity of 700 hp and 667 Nm of torque, the power is transmitted to the rear wheels through a 6-speed sequential transmission by Holinger manufacturing. With a structure made of ultralight materials, this supercar weighs only 972 kg.
Brabham will only produce 70 BT62, equivalent to 70 years of its history at races around the world.
