British aero engine manufacturer Rolls-Royce says it has developed the "world's fastest all-electric aircraft," according to a statement from the company.
The aircraft -- dubbed the "Spirit of Innovation" -- attained a maximum speed of 387.4 mph (623km/h) in flight, which Rolls-Royce said it believed makes it "the world's fastest all-electric vehicle."
Rolls-Royce said in a press statement the Spirit of Innovation set three world records in total, including reaching 345.4 mph over 1.86 miles on 16 November. The company also said the vehicle achieved the fastest time to ascend 3000 meters by one minute, with a time of 202 seconds.
The aircraft flew 300 mph over 9.32 miles in Wiltshire at the UK Ministry of Defence's military aircraft testing site, which is 182 mph quicker than the previous record, the statement said.
The figures have been presented to the sport's global governing body Fédération Aéronautique Internationale (FIA) for verification.
Assembled as part of the Accelerating the Electrification of Flight (ACCEL) project, and funded by the Aerospace Technology Institute (ATI), the Department for Business, Energy & Industrial Strategy and Innovate UK, the aircraft runs on a 400kW electric powertrain. (cnn)
