Rolls-Royce is claiming three world records for its Spirit of Innovation technology demonstrator, which it says is now the world’s fastest all-electric aircraft. The aero engines group has submitted data to the Fédération Aéronautique International, seeking validation of records it says were set in flights this week at the UK Ministry of Defence’s Boscombe Down experimental aircraft testing site.

On November 16, the company says, the converted NXT Next kitplane reached a speed of 345.4 mph over a three-km distance, beating the previous top speed of just 132 mph set in 2017 by France’s Jean Luc Soullier in an Extra 330LE aircraft powered by an electric motor developed by Siemens. In subsequent flights, the Spirit of Innovation reached a speed of 330 mph over a 15-km distance, which was 182 mph faster than the previous record, and also set a new record for climbing to an altitude of 3,000 meters (9,843 feet) in 202 seconds (60 seconds faster than the existing record).
