Two SUVs with some similarities, but otherwise different in most aspects such as the powertrain, model year, market segment, horsepower, fuel economy, ground shadow size, and maximum occupancy. First of all, the 2016 RX 350 has a more powerful engine than the 2014 INFINITI QX60 Hybrid, and it gets 3.5 fewer miles on a gallon of fuel. Also, the INFINITI QX60 Hybrid has a slightly larger body than the RX 350. In addition, you'll seat two more passengers in the INFINITI QX60 Hybrid than in the Lexus RX 350. Among similarities are the body structure, market segment, starting price, and height.
