Two Sedans with some similarities, but otherwise different in most aspects such as the modifications, model year, horsepower, fuel economy, ground shadow size, and height. First of all, the 2016 WRX STI has a more powerful engine than the 2014 CC, and it gets 3.5 fewer miles on a gallon of fuel. Also, the WRX STI is slightly smaller, but the roofline is taller than that of the CC. Among similarities are the body structure, market segment, starting price, and maximum occupancy.
