Elon Musk unveils flying car explained: How does Tesla Roadster work? Timeline of a car that was first revealed in 2008

Tesla’s next-generation Roadster is being presented as more than an electric sports car, with the company highlighting a design that combines extreme acceleration, rocket-style thrusters and the possibility of brief airborne manoeuvres. A video showing the car travelling upside down along a curved ramp, briefly leaving the surface and landing again has added to the attention surrounding the vehicle. However, the demonstration alone does not establish that the production car will be capable of sustained flight or that such manoeuvres will be possible in real-world driving conditions.

The Roadster builds on Tesla’s original ambition to make electric cars fast and desirable, while introducing technologies that the company says could push the limits of conventional road-car performance. Its proposed configurations, pressure-vessel system, aircraft-inspired styling and minimalist cabin are central to that pitch.

How the Tesla Roadster’s thruster system works

Unlike a conventional car, which relies on its tyres to transfer power to the road, the new Roadster is being presented with a system of cold-gas thrusters developed with SpaceX-related technology. The system is intended to deliver additional thrust, potentially improving acceleration and enabling brief movements beyond what tyre grip alone would permit.

Tesla says the thrusters can generate around four to five times the force produced by the tyres. If achieved under the relevant operating conditions, that additional force could substantially increase acceleration because the acceleration of an object depends on the net force applied to its mass.

The company’s concept involves using compressed gas to produce thrust. SpaceX has used thrusters to manoeuvre spacecraft for decades, but adapting such technology for a road vehicle requires different hardware, packaging and control systems.


The proposed Roadster configurations include the following:

• Performance: A two-seat, road-ready configuration featuring active aerodynamics and a suction system. Tesla claims it can accelerate from 0 to 60 mph in under 1.6 seconds.
• Thrust: A two-seat, race-ready configuration that combines suction technology with rear-mounted cold-gas thrusters. Tesla claims a 0-60 mph time of under 0.9 seconds.
• Rocket: A single-seat, air-ready configuration featuring suction technology and thrusters positioned around the vehicle's perimeter. Tesla says these could support forward and upward acceleration, as well as lateral and rotational movement. The company claims a 0-60 mph time of under 0.59 seconds and a top speed exceeding 230 mph.

These are manufacturer-stated figures and capabilities. Their real-world performance will depend on the final vehicle, operating conditions and the extent to which the proposed systems are implemented in a production model.

Why Tesla is packing the Roadster with pressure vessels

Tesla says the Roadster’s available internal spaces are being used to accommodate Carbon Fiber Overwrapped Pressure Vessels, or COPVs, which store compressed gas for the thruster system.

The vessels are designed to hold gas under pressure, with a carbon-fibre composite overwrap providing structural reinforcement. According to Tesla’s concept, fitting more compressed-gas storage into the vehicle could allow the thrusters to operate for longer periods.

That could matter if the system is used for brief airborne manoeuvres or additional thrust during acceleration. However, the amount of gas the vehicle can carry, the duration for which the thrusters can operate and the conditions required for any airborne movement have not been independently established here.

The claim that every usable void in the car is occupied by pressure vessels also raises practical engineering considerations, including packaging, safety, weight and the space available for occupants and other vehicle systems. The final production design will determine how these competing requirements are balanced.

Can the Tesla Roadster actually fly?

Tesla’s proposed thruster arrangement has prompted comparisons with flying vehicles, but the distinction between a brief airborne manoeuvre and sustained flight is important.

A conventional car depends on tyre contact with the road for traction. A vehicle equipped with sufficiently powerful thrusters could, in principle, generate force independently of that contact. The Roadster’s proposed system is intended to extend the car’s capabilities beyond those of a typical tyre-driven vehicle.

The demonstration showing the car leaving a ramp and landing again does not, by itself, establish that the Roadster can fly independently over meaningful distances, hover or operate like an aircraft. Those capabilities would require evidence of the system’s performance, stability, controls, endurance and safety.

Tesla has also described the Roadster’s rocket configuration as capable of forward, upward, lateral and rotational movement. These remain manufacturer-stated capabilities until demonstrated and verified under clearly defined conditions.

Tesla Roadster’s exterior: Inspired by the SR-71 and F-35

Tesla says the Roadster’s design draws inspiration from the SR-71 reconnaissance aircraft and the F-35 fighter jet. The references point towards an emphasis on aerodynamic forms and a more performance-focused appearance.

The company’s broader design language has also changed since the Roadster was last revealed. Tesla’s earlier identity was closely associated with its S3XY model lineup, while more recent projects such as the Cybertruck, Cybercab and Optimus have explored markedly different shapes and design approaches.

The Roadster’s exterior features include concealed headlights, a full-length taillight and flush-mounted surfaces. Lightweight wheels are also part of the design, while titanium accents add to its performance-oriented styling.

Tesla has described the paint finish as Ano White, claiming it offers protection against ultraviolet exposure and cryogenic conditions, along with electrostatic dissipation and corrosion resistance. The company has also highlighted Gold Glazed tinted glass, which it says draws inspiration from the copper coating used on spacesuit visors.

These finishes and materials form part of Tesla’s stated design concept; their final specifications and availability will depend on the production vehicle.

Inside the Tesla Roadster: A minimalist cabin

The Roadster’s interior follows a minimalist approach, with Tesla highlighting a combination of restrained styling and performance-focused materials.

The cabin is described as featuring an Ultrawhite finish, grey microsuede details and bolsters. Magnesium, titanium and carbon fibre are among the materials highlighted for the interior and vehicle construction.

Tesla’s proposed layout also includes manual controls and a fixed seat position. These choices suggest an emphasis on a carefully defined driving position rather than a cabin dominated by extensive seat adjustments and conventional luxury-car features.

The vehicle’s seating arrangement varies by configuration. Tesla describes the Performance and Thrust versions as two-seaters, while the Rocket version is presented as a single-seater to accommodate its more specialised thruster arrangement.

The extent to which these interior details, materials and layouts will appear in the final production model remains subject to the finished vehicle’s specifications.

Tesla Roadster range and performance claims

Beyond its acceleration figures, Tesla has cited a range of more than 300 miles for the Roadster. The company has also claimed that the vehicle can reach a top speed exceeding 230 mph in the Rocket configuration.

These figures place the Roadster’s advertised performance at the centre of its identity. However, acceleration, top speed and range are different measures, and the conditions under which each figure is achieved matter. Final production specifications and independent testing will be important in establishing how the vehicle performs outside the company’s claims.

The thruster system adds another layer of uncertainty because its use could involve trade-offs involving compressed-gas capacity, vehicle mass, packaging and operating time. Tesla’s claim that more stored gas could allow longer thrust-assisted manoeuvres does not, on its own, establish a specific flight duration.

From the 2008 Roadster to Tesla’s latest ambition

When Tesla introduced its original Roadster in 2008, the car had a clear purpose: to demonstrate that an electric vehicle could be fast, desirable and exciting to own. It helped establish the idea that an electric car did not have to be positioned solely as a practical or environmentally conscious alternative.

Tesla is now presenting the next-generation Roadster as a much more ambitious project. Rather than focusing only on electric performance, the company is promoting a combination of rapid acceleration, advanced materials, aircraft-inspired styling and rocket-style propulsion.

Tesla has described the new Roadster as representing a historic moment and as potentially being “the best of the last human-driven cars.” The phrase reflects the company’s framing of the vehicle as a high-performance car at a time when the automotive industry is increasingly exploring automation and other new technologies.

Whether the Roadster delivers on that ambition will depend on the production model and independent verification of its performance claims. For now, its proposed thrusters, compressed-gas storage system and airborne demonstrations distinguish it from conventional electric sports cars, but they do not yet establish that every advertised capability will be available in a road-going vehicle.
