Tesla Roadster could be quickest car ever built

Tesla has unveiled the long-awaited Roadster with a performance claim that, if verified, would rewrite the automotive record books. 

During a livestream reveal, the company said its flagship electric sports car accelerated from 0-60mph (97km/h) in just 0.81 seconds, a figure that would place it comfortably ahead of today's fastest hypercars and potentially make it the quickest-accelerating production car ever built.

The reveal also marked the first public appearance of the second-generation Roadster after almost a decade of delays and development.

After almost a decade of delays, shifting timelines and increasingly ambitious promises, Tesla has finally revealed the car at the centre of one of the automotive industry's longest-running development stories.

And if the company's latest numbers are accurate, the wait may have been worth it.

During the reveal livestream, Tesla displayed a recorded 0-60mph (97km/h) sprint in just 0.81 seconds, comfortably breaking through a performance barrier many thought would remain out of reach for a production vehicle.

That number is difficult to comprehend.

For years, the world's quickest production cars have fought over mere tenths of a second.

Electric hypercars such as the Rimac Nevera, Nevera R and Aspark Owl have all pushed acceleration to extraordinary levels, but Tesla's claim sits in another league entirely.

If the Roadster achieves its promised acceleration in customer-deliverable form, it would effectively slash almost a full second from the benchmark set by today's quickest road cars.

Tesla says the performance comes from a combination of electric propulsion, advanced aerodynamics and a SpaceX-inspired compressed-air thrust system.

During the presentation, engineers revealed the Roadster uses two ultra-high-pressure air tanks feeding 10 nozzles positioned around the vehicle.

The system develops more than 80kN of thrust, with presenters claiming exhaust velocity exceeds the speed of sound.

"We wanted to break the laws of physics," a Tesla engineer said during the reveal.

When the 0.81-second result appeared on screen, Musk appeared delighted.

"Well, I said less than one second," he joked.

The Tesla chief executive then suggested the company still has room to improve.

"The production car will actually do better than that," Musk said.

"We'll just ride the limit of don't detach the retina of the human in the car."

Beyond straight-line performance, Tesla says the Roadster incorporates a fan-assisted ground-effect system capable of generating more than 2G of downforce.

Musk claimed the technology would allow the Roadster to "crush every track record that has ever existed".

The production vehicle shown during the livestream also revealed a dramatic evolution from the four-seat concept unveiled in 2017.

The new Roadster is now a two-seat sports car featuring steer-by-wire controls, an aerospace-inspired design and technology heavily influenced by Tesla's collaboration with SpaceX.

As extraordinary as Tesla's claims are, they remain exactly that for now: claims.

Independent testing and verification will ultimately determine whether the Roadster can deliver the numbers promised on stage.

Tesla's claimed 0.81-second sprint would sit well beyond the current crop of hypercars and, if achieved in production specification, establish a new benchmark for acceleration.

What is already clear is that Tesla has shifted the Roadster conversation beyond electric vehicles and into territory that feels closer to aerospace engineering than conventional automotive development.

If even a portion of the company's promises are realised, the Roadster could become one of the most consequential performance cars ever produced.

Tesla says production is scheduled to commence in 2028.
