The 8 was sold in the United States with an unusual marketing approach that acknowledged that the previous Dauphine had many shortcomings for American owners, and that the 8 was an improvement. While an all new engine was built that was more powerful, and many changes were made, most of the criticism summarized the 8's shortcomings when driving on the recently constructed United States Interstate Highway System as the car was built for French driving conditions which were much more localized. When driving the 8 in city environments, it is nimble and easy to get around crowded conditions. France didn't begin to build the Autoroutes of France until French Law 55-435 was passed April 18, 1955 to create a similar highway system previously built in Germany, called the Autobahn during the 1930s.
