Two SUVs with some similarities, but otherwise different in most aspects such as the model year, horsepower, fuel economy, ground shadow size, and height. First of all, the 2013 Tucson has a more powerful engine than the 2016 CX-3, and it gets 6.7 fewer miles on a gallon of fuel. Also, not only Tucson is slightly larger, but it's also taller than the CX-3. Among similarities are the body structure, starting price, and maximum occupancy.
