Two SUVs with some similarities, but otherwise different in most aspects such as the starting price, horsepower, fuel economy, ground shadow size, height, and maximum occupancy. First of all, the 2016 Acura MDX is priced $6,885 lower compared to the base MSRP of the 2015 Porsche Macan. Also, the 2015 Macan has a more powerful engine and gets 3 mpg less than the 2016 MDX. In addition, the MDX body is slightly larger than the Macan, and in addition to that, it's also taller. And finally, you'll seat two more passengers in the Acura MDX than in the Porsche Macan. Among similarities are the body structure and market segment.
