Two Sedans with some similarities, but otherwise different in most aspects such as the model year, modifications, starting price, horsepower, and fuel economy. First of all, the 2013 Mercedes-Benz S-Class is priced $23,000 lower compared to the base MSRP of the 2016 Jaguar XJ XJR, which is newer by three model years. Also, the 2016 XJ XJR has a more powerful engine than the 2013 S-Class, but it gets 1 more mile on a gallon of fuel. Among similarities are the body structure, market segment, ground shadow size, height, and maximum occupancy.
