Both cars are similar in many ways and different in so much more other ways. For example, both cars are sports cars, where they share most of the main aspects of sports cars like, light weight, two doors, rear engine, sport seats, rough ride, lots of safety features and lots of power. The two cars have an all wheel system and that is to maintain all the power which will be difficult to manage. They are both made by German automobile manufacturers and both got so much attention by the sports cars audience.

The Bugatti holds the world record for top speed for production cars which is 253mph.
