Two SUVs with some similarities, but otherwise different in most aspects such as the model year, starting price, horsepower, and fuel economy. First of all, the 2013 Lexus RX 350 is priced $6,190 lower compared to the base MSRP of the 2016 Infiniti QX70, which is newer by three model years. And finally, the 2016 QX70 has a more powerful engine than the 2013 RX 350, and it gets 2 fewer miles on a gallon of fuel. Among similarities are the body structure, market segment, ground shadow size, height, and maximum occupancy.
