The Acura MDX’s reputation for high reliability and rock-solid safety make it an appealing choice in the luxury SUV segment. In addition, the MDX has a starting price on the lower end compared to most of its competitors, making it a value in the segment. An available hybrid powertrain offers more horsepower and better fuel economy. The RDX shows off the sharp styling, high-tech features and distinguished practicality that Acura is known for, in a smaller, maneuverable package. The elegant interior includes plenty of user-friendly tech features. With its excellent resale value as well, it’s an impressive option in the segment.

Acura MDX Advantages

The MDX is the larger of the two SUVs, with enough room to carry seven passengers. There's also an available hybrid powertrain.

Acura RDX Advantages

Smaller and sportier, the RDX offers tech and quality at a value price for a luxury SUV.


Both offer the luxury, reliability and performance that are synonymous with Acura.

Final Recommendation

The reasonable price for a luxury SUV that Acura offers makes the MDX and RDX great options in the class. The RDX style doesn’t attract a ton of attention but shines in all other areas. The MDX is Acura’s bigger SUV option with more cargo and people space if needed. Choosing one over the other simply depends on your budget and the amount of people and gear you want your SUV to carry.
