This independent simulator explores the fan-car and cold-gas concepts described in the October 2026 Roadster reveal. It is not affiliated with Tesla or a validated engineering model of its car.
What is modeled
Six-degree-of-freedom rigid-body motion, four spring/damper tire contacts, load-limited tire friction, nearby-surface suction, aerodynamic drag, rear boost, lift and attitude impulses. Gravity remains world-down. Fan seal drops as the vehicle separates from the surface.
Gas and the flight computer
The tank is represented by usable total impulse (kN·s), not guessed tank pressure. Every propulsion and attitude command spends that shared budget. Nozzle-flow, temperature, pressure regulation, changing propellant mass and real control allocation are simplified. Assisted landing uses the same force and gas limits as manual input.
The reverse-fan experiment
No verified source found says reversed fans softened the reveal landing. This optional model assumes suitable ducts and skirts can create an air cushion close to a surface. Force falls off with clearance and takes time to build. Its strength is adjustable independently; that is a design experiment, not an assertion that Tesla's fans can do it.
Starting assumptions
1,900 kg total mass; 1 MW drive power; 2 body-weights of suction; 60 kN rear thrust; 42 kN lift; 200 kN·s total impulse. These intentionally do not combine all published best-case claims. Aero and tire coefficients are simplified. The battery model assumes 115 kWh for energy accounting; this is not a confirmed production battery capacity.
How to compare landings
Select Landing study. Run once with the flight computer and cushion off, once with only the cushion, and once with only the flight computer. Reset returns the same height and full resources. Compare touchdown speed, gas remaining and exported telemetry. Lower speed is a softer landing; the load-factor reading includes approximate suspension forces.
Known limits
Surface contacts use rays and simplified hull contact. Tires, suspension, aerodynamics and collisions are approximations; narrow edges and extreme speeds can expose them. No fluid simulation, real Tesla flight controller, production certification, water physics or damage mechanics. The facility is a testing ground, not a real location map.

Later: the game
Hudson's backlog: canyon and bridge jumps, ponds, commute shortcuts, a departing car ferry with a time and gas budget, a GTA-style world, manual and automated controls, and possible Stripe upgrades. No payments are connected in this simulator.
