2025 Acura RDX vs. Lexus RX Spec Highlights
When evaluating 2025 Acura RDX vs. Lexus RX specs, one thing becomes clear: The RX brings more to the road. With its robust performance and elevated comfort, the Lexus model makes every mile more enjoyable for drivers in Fairfield County.
Engine Comparison
While the RDX features a 2.0-liter turbo four-cylinder engine that puts out 270 horsepower and 280 pound-feet of torque, it falls short of the standard 2.4-liter turbo four-cylinder motor that powers the Lexus RX 350. With 275 horsepower and 317 pound-feet of torque, you'll outpace the Acura model.
To put this power into perspective, the Lexus SUV can manage a 3,500-pound towing capacity. The Acura vehicle can't pull half of that, topping out at a 1,500-pound towing capacity.
Another detail that elevates the Lexus RX above the RDX in this specs comparison is the availability of both a 2.5-liter four-cylinder hybrid engine and a 2.5-liter four-cylinder plug-in hybrid powertrain for fuel-saving capabilities that the RDX can't match.
Size Comparison
The Lexus RX is the larger of the two models, standing at 192.5 inches long, 75.6 inches wide, and 67.3 inches tall. Meanwhile, the RDX is 187.4 inches long, 74.8 inches wide, and 65.7 inches tall.
The larger dimensions of the Lexus model make for more overall passenger room. For example, you'll have 1.7 inches more front hip room, more than half an inch extra rear headroom, and 6 more inches of rear hip room than the RDX, making the Lexus SUV a more preferable option for road trips.
Acura RDX vs. Lexus RX 350 Reliability & Safety Features
Reliability is integral to the luxury driving experience – if you want to enjoy your time cruising the streets in Greenwich, CT, and beyond, you'll want to do it in a model you can depend on. According to J.D. Power, the Lexus RX scores 85 out of 100 in the Quality & Reliability category, and an 85 out of 100 Consumer Rating overall.
The Acura SUV isn't quite as favored, earning a Quality & Reliability score of 81 and an overall Consumer Rating of 78 out of 100. It's no surprise that reliability ratings often favor the Lexus model, thanks to the brand's well-established reputation for quality.
This ties into the emphasis that these models place on safety. While the RDX features the AcuraWatch suite of assistive features, it's not quite as robust as the Lexus Safety System+ 3.0 system. Choose the RX, and you'll be supported by standard Intuitive Parking Assist with Auto Braking – a feature missing on the base model of the RDX – to help prevent collisions when reversing.

I recently purchased a Lexus RX 350 from DARCARS Lexus of Greenwich, and I couldn’t be happier with the experience. Harold was my salesperson, and he was absolutely fantastic. He was attentive, informative, and made sure I was fully educated on all the car’s features. What really stood out was how patient he was in answering all of my questions and even taking the time to set up the car before I left. Harold went above and beyond to ensure everything was perfect, and he followed up after the sale to make sure I was satisfied. Exceptional service and a great buying experience!
