Which car is faster sallen or bugatti?

Generally, a Bugatti is faster than a Sallen. There's no single "Sallen" car model; Sallen is a small, specialized car manufacturer that builds highly customized and often very fast cars, but they don't typically compete directly with the top speeds of established supercar brands like Bugatti. Bugatti's models (like the Chiron and Veyron) are known for achieving extremely high top speeds. Therefore, a comparison needs to be made on a model-by-model basis.
