The Tesla Roadster is far from the first car to use fans for downforce

Tesla's upcoming Roadster has generated significant buzz for its reported use of fans to increase downforce, a feature intended to enhance grip and performance. However, this engineering approach is not a new invention in the automotive world. Historically, several iconic vehicles have utilized fan-assisted aerodynamics to achieve superior track performance. Notable examples include the Chaparral 2J, often referred to as the 'sucker car,' which used a dedicated engine to power fans that sucked air from beneath the chassis to create a vacuum effect. Similarly, the Brabham BT46B Formula One car famously employed a large fan at the rear to gain a competitive edge during the 1978 season. By examining these historical precedents, it becomes clear that while Tesla is modernizing the technology for a consumer electric vehicle, the concept of using fans for aerodynamic downforce has a rich and storied history in racing engineering.
