List of vehicle speed records

From Wikipedia, the free encyclopedia

Remove ads

The following is a list of speed records for various types of vehicles. This list only presents the single greatest speed achieved in each broad record category; for more information on records under variations of test conditions, see the specific article for each record category. As with many world records, there may be some dispute over the criteria for a record-setting event, the authority of the organization certifying the record, and the actual speed achieved.

Land vehicles

More information Category, Speed (km/h) ...
  1. Average over two subsequent runs in opposite directions over a 1 mile (1.6 km) course, with flying start[1]
  2. Average over 1 mile (1.6 km), with a flying start
  3. Average over two subsequent runs with four hours to work on the vehicle in impound[5]
  4. Average over 1 kilometre (0.62 mi), with a flying start
  5. Average over two subsequent runs in opposite directions over a 1 kilometre (0.62 mi) course, with flying start[1]
  6. Average over 50 metres (160 ft)[9]
  7. Unpaced on a straight surface -0.6% grade;[11] average over 200 metres (660 ft), with flying start (For other cycling records, see cycling records)
  8. For vehicles powered directly by solar power, without batteries

Perspective

Aircraft speed records are based on true airspeed, rather than ground speed.

More information Category, Speed (km/h) ...
  1. Mach number depends on ambient temperature, and thus altitude, as well as speed; it is not a direct measure of speed.
  2. Over a 3-kilometer course
  3. Average speed over an out-and-return course of 500 km

Noted unofficial records

  1. Unofficial helicopter speed records by the Sikorsky X2 (460 km/h on 15 September 2010) and the Eurocopter X3 (472 km/h on 7 June 2013) would surpass this record if accepted.
  2. Greater speeds reportedly achieved by rigid airships, including 140.3 kilometres per hour (87.2 mph) by the American USS Macon (ZRS-5), are not recognized by the FAI, because these runs did not account for wind speed by flying a set course in both directions.[46]

Watercraft

More information Category, Speed (knots) ...
  1. Ground effect vehicles (a.k.a. "Wing-In-Ground effect vehicles") are classified as maritime vessels, rather than aircraft, by the International Maritime Organization.[62]
  2. Measured over 1 km with a flying start

Spacecraft

Summarize
Perspective

In order to unambiguously express the speed of a spacecraft, a frame of reference must be specified. Typically, this frame is fixed to the body with the greatest gravitational influence on the spacecraft, as this is the most relevant frame for most purposes.[67] Velocities in different frames of reference are not directly comparable; thus the matter of the "fastest spacecraft" depends on the reference frame used.

Because of the influence of gravity, maximum velocities are usually attained when a spacecraft is close to its primary body: either just after launch, at a point of closest approach (periapsis), or during the early stages of atmospheric entry.

  1. Speed records in this class are generally reported by the spacecraft operator and not independently verified.
