Tesla promotes its Roadster as a two-seat electric sports car available by reservation, with active aerodynamics and a multi-mode suction system intended to increase downforce on roads and racetracks. The company says optional SpaceX components can further alter the vehicle’s performance. Tesla frames the car as incorporating “a rocket” after previously sending a Roadster into space aboard a rocket. Tesla says the Roadster’s multi-mode fan and ground-sealing system pulls air from beneath the vehicle to generate suction-based downforce, including at zero speed. The company claims the system could provide enough suction to hold the vehicle upside down while stationary. Powered fans and active wings are designed to maximize traction and cornering speed in different conditions. Tesla also describes a next-generation steer-by-wire system, plus a Track Mode that lowers the car and changes its suspension; drivers could select high-downforce or low-drag modes for track use. Tesla says advanced cold-gas thrusters with electric actuators can make micro-adjustments within fractions of a second and help stabilize the vehicle in flight.
