Confident, quick, and clean — the right move I bought a 2021 Acura RDX A-Spec after a long stretch of research, quotes, and test drives. Came from a 2015 Mazda6—solid, efficient—but I was ready for something with more presence and power. The RDX gave me that without stepping into overpriced territory. The turbo delivers. Paired with the 10-speed, it moves when I need it, cruises when I don’t. Sport mode plus paddles gives just enough edge without trying too hard. The ride feels tight and grounded, and the A-Spec trim looks clean and confident—no chrome, no fluff. Inside, it’s a clear step up. Ultrasuede, ambient lighting, panoramic roof—it feels elevated, not loud. The ELS Studio sound system is better than I expected, no exaggeration. Fuel economy is lower than my old Mazda. I’m averaging 23–24 mpg mixed, which is fair for an AWD turbo, but it’s a drop. I expected it, but it’s worth noting. The button shifter is fine, but the tray underneath it is a catch-and-forget zone. I’ve left my phone in there more than once because of how tucked away it is. Not a flaw, just an adjustment. Same with the seat moving back when I shut the car off. Lighting fades, dash does a little goodbye animation. I’ve never had a car do all that before. It’s subtle, but now I notice. No issues with the infotainment or CarPlay. I plug in, it works. I’m not paying extra for AcuraLink remote start when the fob does the job just fine. Overall, this RDX feels like a clean step forward. It’s fast when I want it, quiet when I need it, and doesn’t feel like it’s trying to impress anyone. It just handles its business. I’d buy it again.

This car gets high marks for interior design, efficient use of space and comfort. On the other hand fuel economy is pretty poor considering vehicle size and throttle response. What is really disappointing is the impact of the noise canceling technology on the ability of the paying customer to control the sound of the audio system. If you want more bass tones you are out of luck. The more you turn the bass up the more the system cancels it out and the worse it sounds. Acura should just build a quiet car to begin with and not rely on electronic mumbo jumbo.

We decided between Lexus and Acura. Though Lexus scores just above in reliability and ease of tech features we chose the Acura RDX. The Lexus RX was too big and the NX too small for our needs and the Acura RDX was just the right in between size of those two cars. It has very good trunk space with even more storage underneath. There are levers in the trunk to let down the seats (a feature missing on the Lexus, if you are not tall you have to go to the backseat to let them down.) The seats also lay flat as opposed to quite an angle on the Lexus. The passenger seat on the Acura has all the same power comfort adjustments as the driver seat, we couldn’t find one Lexus with that, not even on the luxury trim. Acura also makes is easy to know what is in the car because all their trim levels have a sameset of features so looking for a used car was much easier than Lexus because though Lexus has trim levels customers can add on individual features that don’t come on the trim so you never know if what you are looking for is on the car . Even at the luxury level we could not find an NX with 360 view or Heads-up. I am sure they are out there just pretty hard to find. On the Acura we knew the Advanced package always had those features so it made looking easier. I also like that Acura has left the dead space underneath the console open for a bit more storage space, you can fit a small purse there. Dead space on the Lexus. So for those reasons we chose the Acura over the Lexus. However they are both very nice cars and I will say all the Lexus Dealerships we went to were superior in their customer service! We just liked the Acura car better.
