Two Sedans with some similarities, but otherwise different in most aspects such as the starting price, horsepower, ground shadow size, and height. First of all, there is a notable difference in the starting price of the 2016 Audi A4, which is $4,600 less than the base MSRP of the 2015 Volvo S80. Also, the 2016 A4 produces fewer horsepower than the 2015 S80. And finally, not only A4 is slightly smaller, but it's also shorter than the S80. Among similarities are the body structure, market segment, fuel economy, and maximum occupancy.
