Two SUVs with some similarities, but otherwise different in most aspects such as the powertrain, horsepower, market segment, starting price, fuel economy, ground shadow size, and maximum occupancy. First of all, the 2015 Chevrolet Suburban has a more powerful engine than the 2016 Mercedes-Benz GL-Class Diesel, and it gets 4 fewer miles on a gallon of fuel. Also, there is a notable difference in the starting price of the 2015 Suburban, which is $14,600 less than the base MSRP of the 2016 GL-Class Diesel. In addition, the Suburban is slightly larger than the GL-Class Diesel. And then, you'll seat one more passenger in the Chevrolet Suburban than in the Mercedes-Benz GL-Class Diesel. Among similarities are the body structure and height.
