Concept
This is a list of the world's record-breaking top speeds achieved by street-legal production cars (as opposed to concept cars or modified cars). For the purposes of this list eligible cars are defined in the list's rules. This list uses a different definition to the List of automotive superlatives. The variation is because the term production car is otherwise undefined. Because of the inconsistencies with the various definitions of production cars, dubious claims by manufacturers and self-interest groups, and inconsistent or changing application of the definitions this list has a defined set of requirements. For further explanation of how these were arrived at see the talk pages of both this article and the above link. After the Koenigsegg Agera RS was found not eligible for this list since only 11 cars had engines rated higher than 865 kW, the former 25 car minimum was dropped and replaced with new rules based on suggestions by Koenigsegg PR manager Steven Wade. This list is also limited to post World War II production road cars which reached more than , older cars are excluded even if they were faster. The Benz Velo as the first petrol driven car is the only exception. For the purposes of this list, a production car is defined as a vehicle that is: constructed principally for retail sale to consumers, for their personal use, to transport people on public roads (no commercial or industrial vehicles are eligible) available for commercial sale to the public in the same specification as the vehicle used to achieve the record manufactured in the record-claiming specification by a manufacturer whose WMI number is shown on the VIN, including vehicles that are modified by either professional tuners or others that result in a VIN with a WMI number in their name (for example, cars manufactured by RUF with Porsche parts and RUF's WMI W09 are eligible; cars modified by them with Porsche's WMI, WP0, aren't) pre-1981 vehicles must be made by the original vehicle manufacturer and not modified by either professional tuners or individuals street-legal in its intended markets, having fulfilled the homologation tests or inspections required under either a) United States of America, b) European Union, or c) Japanese law to be granted this status sold in more than one national market.
