Today Hyperloop One claimed that its demo pod [prnewswire.com] reached 192mph (310 kph) on the 500m (1/3 mile) test track that the startup built outside of Las Vegas. Hyperloop One showed off that demo pod last month—it's basically an 8.7m (28.5 ft) carbon-fiber shell on a magnetically levitating chassis.
This test run follows on a "Phase 1" [arstechnica.com] test that sent a bare-bones sled down the test track at 70mph. At the time, Hyperloop One had said Phase 2 would involve getting to 250mph, but in a recent press release, the startup said that the 192mph test run this month satisfied Phase 2 development goals. Ars has reached out to Hyperloop One for clarification, and we'll update when we receive a response.
Although no media were present, Hyperloop One claims that in this most recent test, its large pod "accelerated for 300 meters and glided above the track using magnetic levitation before braking and coming to a gradual stop."
