Today, [[BMW]], [[Audi]], [[Volkswagen]] and [[Mercedes-Benz]] limit their production cars to {{cvt|250|km/h|0}}.  Certain [[Audi Sport GmbH]] and [[Mercedes-AMG|AMG]] cars, and the [[Mercedes-Benz SLR McLaren|Mercedes/McLaren SLR]] are exceptions. The BMW Rolls-Royces are limited to {{cvt|240|km/h|0}}. [[Jaguar Cars|Jaguars]], although British, also have a limiter, as do the Swedish [[Saab Automobile|Saab]] and [[Volvo Cars|Volvo]] on cars where it is necessary.

German manufacturers initially started the "[[gentlemen's agreement]]", electronically limiting their vehicles to a top speed of {{cvt|250|km/h|0}},<ref>{{cite web|url=http://www.autoevolution.com/news/gentlemens-agreement-not-so-fast-sir-47736.html|title=Gentlemen's Agreement: Not So Fast, Sir!|author=Bogdan Popa|work=autoevolution|date=28 July 2012}}</ref><ref>van Gorp, Anke.

ISSN 1574-941X</ref> since such high speeds are more likely on the [[Autobahn]].  This was done to reduce the political desire to introduce a legal speed limit.

In European markets, [[General Motors Europe]] sometimes choose to discount the agreement, meaning that certain high-powered [[Opel]] or [[Vauxhall Motors|Vauxhall]] cars can exceed the {{cvt|250|km/h|0}} mark, whereas their [[Cadillac]]s do not.  [[Ferrari]], [[Lamborghini]], [[Maserati]], [[Porsche]], [[Aston Martin]] and [[Bentley]] also do not limit their cars, at least not to {{cvt|250|km/h|0}}. The Chrysler [[Chrysler 300#300C|300C]] SRT8 is limited to {{cvt|270|km/h|0}}.  Most Japanese domestic market vehicles are limited to only {{cvt|180|km/h|0}} or {{cvt|190|km/h|0}}.<ref>{{cite web|url=http://search.japantimes.co.jp/cgi-bin/fv20080413pl.html |title=Why Japan finally got its foot off the brake &#124; The Japan Times Online |publisher=Search.japantimes.co.jp |date=2008-04-13 |access-date=2012-11-08}}</ref>  The top speed is a strong sales argument, though speeds above about {{cvt|300|km/h|-1}} are not likely reachable on public roads.
