A scramjet (supersonic-combustion ramjet) is a ramjet engine in which the airflow through the whole engine remains supersonic. The highest speed attained by a rocket-powered airplane, NASA's X-15 aircraft, was Mach 6.7. The fastest air-breathing, manned vehicle, the SR-71, achieved slightly more than Mach 3. The X-43A more than doubled the top speed of the jet-powered SR-71.
The C5-Blast prototype isn't shown on the track in the video below, but you can get a taste of the jet engine-like sound the kart's fans generate. At the moment, the fastest accelerating EV in the world is Grimsel, which hits 100 km/h (62 mph) in 1.513 seconds.
