Tesla has revealed more details about the new Roadster‘s aerodynamic system, including powerful fans capable of generating enough suction to hold the electric sports car upside down while stationary.
Unveiled on on Thursday night, the next-generation Roadster combines a ground-effect suction system, active aerodynamics, and SpaceX-inspired cold-gas thrusters. Tesla says the technology will allow the car to achieve extraordinary levels of traction and cornering performance, even at low speeds.
The Roadster has been one of Tesla’s most anticipated vehicles since its original unveiling in 2017. Elon Musk has repeatedly promised performance beyond conventional sports cars, including a SpaceX package that would use thrusters to improve acceleration and handling. Now, nearly nine years later, Tesla has provided its clearest explanation yet of how those technologies work together.
Downforce Without Speed
Unlike traditional aerodynamic systems that rely on airflow generated by vehicle speed, the Roadster uses powered fans to pull air from underneath the car, as we first saw in a patent earlier this year. Combined with seals around the underbody, the system creates suction that pushes the vehicle against the road.
“We have a fan suction system on the bottom of the car that can pull up to two g’s in order to make the car go upside down. And then we borrowed some technology from SpaceX to do the rest,” Musk explained during the unveiling.
Tesla says the system can generate enough downforce to support cornering forces exceeding 2 g, compared with the roughly 1.26 g typically available from the tires alone.
During the demonstration on Thursday night, the system generated over 4,700 kg of downforce, enough to keep it stuck to the “road” while upside down.

The suction system operates in two modes, increasing traction at low speeds before opening front and rear airflow passages to improve performance at higher speeds.
The Roadster also features an adjustable rear wing, with actuators derived from Tesla’s Optimus robot program. Its angle changes automatically to balance downforce and aerodynamic drag.

Meanwhile, cold-gas thrusters provide rapid stabilization adjustments, including when the vehicle is airborne.
If that wasn’t enough, the @Tesla Roadster just did a ‘kickflip’ over the entire Tesla lineup, including the Semi! https://t.co/xUUsDVBNao
