* Italy: Companies like Bugatti (owned by Volkswagen Group, a German company, but designed and largely built in Molsheim, Alsace, France - a point of contention), Lamborghini, and Ferrari are known for their extremely high-performance vehicles that often compete for top speed records.
* Germany: Porsche, BMW, Mercedes-Benz, and Audi all produce high-performance cars capable of very high speeds, often pushing technological boundaries.
* United Kingdom: While not as prolific in the hypercar category as the others, UK manufacturers like McLaren have a strong reputation for high-performance vehicles.
* France (via Bugatti): As noted above, the location of Bugatti's design and manufacturing complicates the question. The company itself is owned by a German company but has a significant French presence.
The "fastest" title often depends on the specific model and any recent records broken, so it's difficult to definitively assign it to a single country.
