Elon Musk is stirring excitement with hints of astonishing sub-second acceleration for the upcoming Tesla Roadster 2 hypercar. The CEO of Rimac, creators of the record-breaking electric car, Nevera R, expressed skepticism, suggesting such performance might require thrusters. Indeed, Musk hinted that the Roadster 2 would incorporate technology from SpaceX’s Starship rockets. Tesla might aim for the 0-60 mph in under a second by employing a downforce technique reminiscent of the banned Formula 1 “fan car” technology.
The Brabham BT46, notorious for its “fan car” advantage, was inspired by innovations like the Chaparral 2J and Tyrrell 008, which used fans to enhance downforce by creating a low-pressure area underneath the car. This strategy kept vehicles tightly grounded, surpassing the performance of traditional spoilers or tunnels.
Tesla has secured a patent for a similar “adaptive vehicle aerodynamics” system, featuring fans and skirts designed to create a vacuum under the car. This setup modifies downforce across different speeds and conditions. The system includes multiple fans in airflow pathways and deployable skirts that interact with the ground. There are two operating modes: one for maximum downforce at lower speeds on smooth terrains, and another for enhanced performance on dynamic, uneven surfaces. A control mechanism adjusts the skirts and fans to optimize driving, enhancing grip and cornering, crucial for setting records.
Whether the acceleration will be boosted by SpaceX-designed thrusters or “wings,” as Musk teased, is yet to be revealed. However, Musk praised the Roadster 2 design team, promising a spectacular demo this year. He also hinted the Roadster 2 might “fly” by 2024 with the upcoming demonstration.
While Tesla focused on projects like the Cybertruck and revamping its product lineup, anticipation for the Roadster 2 is growing. Ironically, this anticipation includes the potential return of fan-based technology.
