If you’re not sure whether to opt for a 2018 Acura MDX or a 2018 Acura RDX, don’t worry – you’re certainly not alone.

Power and Efficiency

When it comes to powertrains, a choice between the 2018 Acura MDX and the 2018 Acura RDX comes down to a choice between performance and efficiency. Both offer a stunning blend of power and economy, but each leans a little more towards one measure.

  • MDX Power and Efficiency: A 3.5L V6 makes up to 290-hp and 267 lb.-ft. of torque while achieving up to 20 mpg in the city and 27 mpg on the highway.**
  • RDX Power and Efficiency: A 3.5l V6 makes up to 279-hp and 252 lb.-ft. of torque while achieving up to 20 mpg in the city and 28 mpg on the highway.**

Interior Space

The MDX and the RDX differ markedly when it comes to interior space. Most importantly, the MDX makes room for up to seven vs. just five with the RDX, so this will be a top pick for large or growing families. It also delivers 14.9 cubic feet of storage space behind the 3rd row, 38.4 behind the 2nd row, or 68 behind the 1st row.

The RDX only offers up to an available 61.3 cubic feet of cargo capacity; it isn’t going to be as handy for, say, taking furniture from Port Washington to Manhasset. However, you really should to ask yourself whether you need those two extra seats. The RDX’s standard cargo capacity of 26.1 cubic feet will make it easier to pack and load during everyday life.


Top-notch technologies are available with both the MDX and the RDX, with options including a power liftgate, adaptive cruise control, satellite navigation, and heated seats.

However, the MDX, as a three-row model, has been made to accommodate longer journeys with more passengers, so it can entertain with a 16.2-inch screen with HDMI input to let you play DVDs or games consoles in the rear. It can also supply an innovative surround-view camera system to provide a digital bird’s-eye view of the surrounding area.
