Cars, like the people that create them have distinct characters. Some of that comes down to the individuals responsible for the design and development and the corporate culture they work in. Other aspects of automotive ethnicity come the places where they were created. Despite the differences between the various German brands, they all share some common DNA, in particular, the way they behave at elevated speeds on highways like the Autobahn. Such is the case for the latest generation Audi A4 that arrived on American shores earlier this year.
