Two SUVs with some similarities, but otherwise different in most aspects such as the powertrain, market segment, starting price, horsepower, fuel economy, ground shadow size, and maximum occupancy. First of all, the 2018 Acura MDX Hybrid has a more powerful engine than the 2018 Alfa Romeo Stelvio, but it gets 3 more miles on a gallon of fuel. Also, there is a notable difference in the starting price of the 2018 Stelvio, which is $10,105 less than the base MSRP of the 2018 MDX Hybrid. In addition, the MDX Hybrid is slightly larger than the Stelvio. And then, you'll seat two more passengers in the Acura MDX Hybrid than in the Alfa Romeo Stelvio. Among similarities are the body structure, market segment, and height.
