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.

List rules
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 above link.
Post 1945 and over 124 mph (200 km/h) only
This list is also limited to post World War II production road cars which reached more than 124 mph (200 km/h), older cars are excluded even if they were faster. The Benz Velo as the first petrol driven car is the only exception.
Production car definition
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, if a Porsche-based car is remanufactured by RUF and has RUF's WMI W09, it is eligible; but if it has Porsche's WMI, WP0, it is not eligible)
- 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 law, or (c) Japan) to be granted this status
- sold in more than one national market.
Measurement of top speed
To establish the top speed for cars at least since the 1990s the requirement is, in addition to the above, an independent road test with a two-way run. The mean of the top speed for both runs is taken as the car's top speed. In instances where the top speed has been determined by removing the limiter, the test met these requirements, and the car is sold with the limiter on then the limited speed is accepted as meeting this requirement. For the McLaren F1 the estimation by Car and Driver about the speed at the rev-limiter is used.

Difficulties with claims
Comparing claimed speeds of the fastest production cars in the world, especially in historical cases, is difficult as there is no standardized method for determining the top speed and no central authority to verify any such claims. Examples of the difficulties faced were shown up in the dispute between Bugatti and Hennessey over which car was the world's fastest.
Bugatti Veyron limiter removal
On 4 July 2010 the Bugatti Veyron Super Sport reached 431.072 km/h (267.856 mph) two-way average. Bugatti built 30 Super Sports (5 of them named World Record Edition). At the time the record was set it was known that the customer cars were electronically limited to 415 km/h (257.87 mph). Guinness Book of Records (which had listed speeds by British cars with modified rev limiter as production car records in the 1990s) listed the unlimited 431.072 km/h (267.856 mph) as production car speed record. Yet, 3 years later, after a query by the Sunday Times Guinness' PR director Jaime Strang was quoted: "As the car's speed limiter was deactivated, this modification was against the official guidelines. Consequently, the vehicle's record set at 431.072 km/h is no longer valid." 5 days later it was written on its website: "Guinness World Records would like to confirm that Bugatti's record has not been disqualified; the record category is currently under review." Five days later Bugatti's speed record was confirmed: "Following a thorough review conducted with a number of external experts, Guinness World Records is pleased to announce the confirmation of Bugatti's record of Fastest production car achieved by the Veyron 16.4 Super Sport. The focus of the review was with respect to what may constitute a modification to a car's standard specification. Having evaluated all the necessary information, Guinness World Records is now satisfied that a change to the speed limiter does not alter the fundamental design of the car or its engine."
Cars excluded from the list
Some cars were not considered to be the fastest production vehicles, for various reasons. Here is a list of some well known cars that have not been able to meet standards needed to be the fastest production car.
