Commercial jets are more fuel efficient than your car. The Concorde, a British-French turbojet, had a maximum speed of Mach 2.04, which is over twice the speed of sound. However, it’s heavily debated whether the Concorde or the TU-144, a Soviet supersonic airliner is faster. The TU-144 averaged Mach 1.6, but could fly up to Mach 2.29. The Concorde flew passengers from New York to London is a little over three hours, when it normally takes over seven hours. The TU-144 flew from Moscow to Alma-Ata, but both planes were retired due to fatal crashes and reliability issues.
