What we have here are two Hatchbacks from Honda with some differences, such as the horsepower, maximum occupancy, model year, and fuel economy. First of all, the 2016 CR-Z has a more powerful engine and gets 7.5 mpg less than the 2014 Insight. Also, you'll seat three more passengers in the Insight than in the CR-Z. Among similarities are the body structure, market segment, starting price, ground shadow size, and height.
