Two SUVs with some similarities, but otherwise different in most aspects such as the starting price, model year, horsepower, fuel economy, and maximum occupancy. First of all, there is a notable difference in the starting price of the 2014 Acura MDX, which is $18,310 less than the base MSRP of the 2016 BMW X6, which is two model years newer. Also, the 2016 X6 has a more powerful engine and gets 2.7 mpg less than the 2014 MDX. And finally, you'll seat two more passengers in the MDX than in the X6. Among similarities are the body structure, market segment, and height.
