Two Sedans with some similarities, but otherwise different in most aspects such as the powertrain, model year, starting price, horsepower, fuel economy, and maximum occupancy. First of all, there is a notable difference in the starting price of the 2016 Volvo S80, which is $7,950 less than the base MSRP of the 2014 Mercedes-Benz E-Class Sedan Diesel, which is two model years older. Also, the 2016 S80 has a more powerful engine and gets 3 mpg less than the 2014 E-Class Sedan Diesel. In addition, you'll seat two more passengers in the E-Class Sedan Diesel than in the S80. Among similarities are the body structure, market segment, ground shadow size, and height.
