Two SUVs with some similarities, but otherwise different in most aspects such as the starting price, horsepower, fuel economy, ground shadow size, and maximum occupancy. First of all, there is a notable difference in the starting price of the 2016 Mercedes-Benz GL-Class, which is $17,980 less than the base MSRP of the 2015 Lexus LX 570. Also, a bigger engine usually means less mpg. But the 2016 GL-Class has a more powerful engine and it gets 3 more mpg than the 2015 LX 570. In addition, the LX 570 is slightly smaller than the GL-Class. And finally, you'll seat one more passenger in the Lexus LX 570 than in the Mercedes-Benz GL-Class. Among similarities are the body structure, market segment, and height.
