Two SUVs with some similarities, but otherwise different in most aspects such as the model year, horsepower, fuel economy, ground shadow size, height, and maximum occupancy. First of all, the 2016 MKX has a more powerful engine than the 2014 Enclave, but it gets 1 more mile on a gallon of fuel. Also, the Enclave is both slightly larger and taller than the MKX. In addition, you'll seat two more passengers in the Buick Enclave than in the Lincoln MKX. Among similarities are the body structure and starting price.
