Acura MDX vs Lexus RX 350

Getting into a new SUV can be a fun, yet challenging enterprise. At Ira Acura Westwood, we’ve taken two great models and put them up side-by-side in our Acura MDX vs. Lexus RX 350 comparison. We’re excited for our customers around Westwood, Dedham, Needham, and Norwood, MA, to read about these models and learn our pick for which is the best choice.

Acura MDX Interior

Acura MDX vs Lexus RX 350: Interior Dimensions

Comfort is an essential feature of any vehicle, including for the SUV. As you may be just as likely to encounter difficult terrain as you are highways, being comfortable means you’ll experience the best ride possible. Your passengers will appreciate being able to stretch their legs as well as enjoying freedom of movement. The following hard-number measurements for both the MDX and RX 350 are as follows:


  • Headroom: 38.5 inches/38.1 inches/36.2 inches
  • Legroom: 41.6 inches/38.5 inches/29.1 inches
  • Shoulder Room: 61.9 inches/60.3 inches/55.2 inches
  • Hip Room: 59.3 inches/57.8 inches/40.6 inches

RX 350

  • Headroom: 39.4 inches/39.1 inches
  • Legroom: 44.1 inches/38.0 inches
  • Shoulder Room: 57.8 inches/57.6 inches
  • Hip Room: 56.6 inches/56.1 inches

While the RX 350 offers slightly more headroom and legroom initially, its lack of a third row affects this advantage. The MDX is the bigger vehicle, meaning that it’s designed to comfortably accommodate three rows of passengers. This is more easily seen in the shoulder room and hip room measurements, as the MDX clearly runs past the amount of space offered by the RX 350. With the larger interior environment, the passengers in the MDX can enjoy their luxury ride.

Acura MDX vs Lexus RX 350: Cargo Space

A great aspect of SUV design is the amount of cargo space that’s made available to you. Since you’ll be taking all sorts of adventures, you’ll want to make sure you have the right tools. This can range from surfboards for a sunny beach day, to mountain bikes to tackle the next big trail. Here we’ll see how both vehicles compare in the following measurements:

MDX (Standard / Max)

  • Behind 3rd Row: 16.3 cubic feet/18.1 cubic feet
  • Behind 2nd Row: 39.1 cubic feet/48.4 cubic feet
  • Behind 1st Row: 71.4 cubic feet/95.0 cubic feet

RX 350

  • Behind 2nd Row: 16.0 cubic feet
  • Behind 1st Row: 32.7 cubic feet

You’ll be able to bring more of your accessories and necessities in the MDX, thanks to the generous amount of space made available. While the RX 350 can accommodate most cargo, it lacks the extra space that allows the MDX to be more effective at managing storage.

Acura MDX Tech

Acura MDX vs Lexus RX 350: Connectivity

In this category both vehicles bring their A-game. The MDX shows up with an HD 12.3-inch center display that’s controlled through the True Touchpad Interface™. With the RX 350, it comes equipped with an 8-inch Lexus Multimedia System on a color LCD multimedia display.

Both vehicles offer Apple CarPlay® and Android Auto™ integration as well as Alexa compatibility. Also shared between them is their respective connected service options, which mirror each other pretty well.

The differences arise once you move past that and see what extras are included. With the RX 350, you have access to Bluetooth® and USB smartphone connectivity, a backup camera with dynamic gridlines, and SiriusXM® 3-month Platinum Plan trial subscription. While with the MDX, it has Precision Cockpit™, which is a configurable digital experience when driving; and a 10.5-inch Head-Up Display, which projects info like your speed, AcuraWatch® alerts, turn-by-turn navigation, and more.

Acura MDX vs Lexus RX 350: The Verdict
