Rolls-Royce's All-Electric Airplane Reached a Record 387.4 MPH Top Speed

Rolls-Royce has announced that its all-electric plane, dubbed the 'Spirit of Innovation,' is the fastest of its kind in the world after it reached a maximum speed of 387.4 mph (623 k/h) in recent flight tests. Gizmodo reports: In a recent news release, the company, not to be mistaken for the car company owned by BMW, claimed that the Spirit of Innovation set three new world records earlier this week. On flight tests carried out on Nov. 16, Rolls-Royce said its aircraft reached a top speed of 345.4 mph (555.9 km/h) over 1.8 miles (3 kilometers), exceeding the current record by 132 mph (213 k/h). It broke another record in a subsequent 9.3-mile (15 kilometer) flight, during which it reached 330 mph (532.1 km/h), surpassing the current record by 182 mph (292.8 km/h).

The Spirit of Innovation didn't stop there, though. Rolls-Royce affirms that it smashed another record when it reached 9,842.5 feet (3,000 meters) in 202 seconds, beating the current record by 60 seconds. In the company's view, it also took the title of the world's fastest all-electric vehicle when it reached a maximum speed of 387.4 mph (623 km/h) during its flight tests. The company's aircraft is powered by a 400kW electric powertrain and 'the most power-dense propulsion battery pack ever assembled in aerospace.' 'Following the world's focus on the need for action at COP26, this is another milestone that will help make 'jet zero' a reality and supports our ambitions to deliver the technology breakthroughs society needs to decarbonize transport across air, land and sea,' CEO Warren East said in the news release.
