Corner jets: four, firing down, for lift and landingsMain jets: four in the rear diffuser, fed by one bent pipeBody cut on the centreline; near side removedCold-air smoke, cel-shaded; inside it the car shows as an x-rayAn unofficial illustration of Tesla's Roadster, revealed near Waco on 15 October 2026, in its one-seat Rocket trim. Tesla says it stores about 600 litres of air (about 250 kg) in carbon-fibre overwrapped pressure vessels packed into every usable void, feeding ten cold-gas thrusters; coverage places four main thrusters in the rear diffuser (over 80 kN, Tesla says) and thrusters at the corners that fire down for landings, and fans under the floor give up to 2 g of downforce. The tank layout, the last two jets and the fans' size are guesses, and some reports describe two tanks. The numbers are a model: 596 L at 380 bar (the car's 5,500 psi readout) is 249 kg of air; at about 65 s of specific impulse a 1.4 g hop burns 21 kg and a 0.25 s static fire of the main jets 31 kg. Hops and fires play at a third of real speed.
