Amazingly, Musk has recently announced on Twitter a ‘SpaceX option package’ for the Roadster which will include roughly 10 small rocket thrusters around the vehicle’s exterior. Musk claims that 'these rocket engines dramatically improve acceleration, top speed, braking & cornering. Maybe they will even allow a Tesla to fly…'
While you might think these thrusters need fuel which is at odds with the full electric Roadster, fret not. These thrusters are said to ill be powered by compressed atmospheric air that’s made by a compressor and stored in a tank.
Whether how these thrusters would work remains unknown but it is not hard to imagine these thrusters being installed at the sides of the car firing at their respective directions to improve acceleration, braking and cornering speed.
