 Rolls-Royce's all-electric airplane smashes record with 387.4 MPH top speed

 

Just two months after its maiden flight, Rolls-Royce's "Spirit of Innovation" has hit a top speed of 387.4 MPHtentatively smashing the speed record for electric airplanes, Gizmodo has reported. It also claimed the top speed of 345.4 MPH over a 3 kilometer (1.86 mile) course and lowest time to a 3,000 meter (9,843 feet) altitude (202 seconds). The records have yet to be certified, but if the 345.5 MPH speed stands, it would beat the current record of 213 MPH — held by a Siemens-powered Extra 330LE — by an impressive 132 MPH.
