Acura MDX vs Lexus RX350: Cabin Space

 The 2018 MDX and 2018 RX350 are both midsize SUVs, but their seating capacities are a bit different. The MDX has three rows of seating and can accommodate six or seven passengers, depending on whether you opt for the second-row captain's chairs. The RX350's two rows are plenty roomy for five riders, but that's the limit as far as seating goes.

While each vehicle's first-row seating has all the space you need (well over 40 inches of legroom in each), second-row passengers will find more than 3 inches of extra legroom in the MDX compared to the RX350 (41.4 inches to 38.0 inches). That's a significant difference, one that makes the MDX's rear seating more amenable to taller adults.  

Performance Specs

 Performance-wise, the Acura MDX and Lexus RX350 are a good matchup. Their outputs are roughly equal (just below 300 horsepower), and the MDX's EPA-estimated fuel economy is 19 city and 27 highway mpg.1 Those solid numbers are well-matched by the RX350, which has identical highway mpg. Either ride should help you go further on less fuel.

Both models have automatic transmissions, though the MDX's nine-speed uses a pushbutton gear selector for extra convenience and has a fuel economy advantage over the RX350's eight-speed with conventional gear selector. Unlike the RX350, the MDX offers an available Idle Stop feature for a boost in fuel efficiency.  

Advanced Safety Features

Both vehicles have a bounty of advanced safety features, including a rearview camera to give you a better look at what's going on behind you when you need to back up. Driver assist features, like forward collision warning, lane-keeping assist and adaptive cruise control, also come standard in both.

When it comes to safety scores, however, the 2018 MDX performs a bit better than the 2018 RX350. The MDX gets a NHTSA 5-Star Overall Safety Rating, with five stars each on its frontal and side crash tests. The RX350 gets just four stars overall, earning one less star on its frontal crash test.

2018 Acura MDX vs 2018 Lexus RX350: And the Winner is…

To shoppers near Mission Viejo, Laguna Niguel and Aliso Viejo, the 2018 Acura MDX and 2018 Lexus RX350 both look like top-of-the-line midsize luxury SUVs in many ways. But if safety, seating, and efficiency are the name of your game, you may want to take a closer look at the Acura MDX.
