Two SUVs, but completely different in all significant aspects: powertrain, starting price, horsepower, ground shadow size, height, model year, fuel economy, and maximum occupancy. First of all, there is a notable difference in the starting price of the 2014 Infiniti QX50, which is $28,750 less than the base MSRP of the 2016 Mercedes-Benz GL-Class Diesel, which is two model years newer. Also, the 2014 QX50 has a more powerful engine than the 2016 GL-Class Diesel, and it gets 2 fewer miles on a gallon of fuel. In addition, the QX50 body is significantly smaller than the GL-Class Diesel, and in addition to that, it's also shorter. And then, the Mercedes-Benz GL-Class Diesel seats two more passengers than the Infiniti QX50. Among similarities are the body structure and market segment.
