Tesla's Roadster Downforce Tech Follows a 50-Year-Old Racing Lineage
Tesla's new Roadster uses fans to generate up to 2g of downforce, allowing it to drive upside down. However, this technology is not new; it follows a lineage of racing cars like the 1970 Chaparral 2J and 1978 Brabham BT46, as well as the modern McMurtry Spéirling, which also uses suction to cling to surfaces.
