When it comes to luxury SUVs, the 2025 Acura lineup offers two standout models: the Acura MDX and the Acura RDX. Both vehicles embody Acura's commitment to performance, technology, and comfort, but they cater to different needs and preferences. In this blog post, we'll dive into a comparison of size, cargo space, features, and fuel efficiency, helping you decide between the Acura MDX vs RDX.
Size and Dimensions
Acura RDX Size
The Acura RDX is a compact luxury SUV that is designed for urban versatility and maneuverability. With a length of around 187 inches, a width of around 74 inches, and a height of about 66 inches, the Acura RDX size is ideal for city driving. Its compact dimensions allow for easy parking and agile handling, making it a favorite among drivers who frequently navigate tight spaces.
Acura MDX Size
On the other hand, the Acura MDX is a full size luxury SUV that provides more space for passengers and cargo. Measuring around 198 inches in length, 79 inches in width, and 67 inches in height, the MDX offers a more substantial presence on the road. This larger size translates to a roomier interior, making it a perfect choice for families or those who prioritize passenger comfort.
Cargo Space
When it comes to cargo space, the differences between the RDX and MDX become more pronounced.
- Acura RDX Cargo Space: The RDX offers a respectable 29.5 cubic feet of cargo space behind the rear seats, which can be expanded to 58.9 cubic feet with the rear seats folded down. This is suitable for everyday errands, weekend getaways, and trips to the grocery store.
- Acura MDX Cargo Space: The MDX shines with its 18.1 cubic feet of space behind the third row, which can expand to 48.4 cubic feet with the third row folded down. If you fold down both the second and third rows, you'll have an impressive 95 cubic feet of cargo capacity. This makes the MDX a versatile option for those who need to transport larger items or multiple passengers with their luggage.
Features
Both SUVs are packed with advanced features and technology, but there are some differences worth noting.
- Acura RDX Features: The RDX comes standard with a 10.2-inch infotainment display, a premium audio system, and a suite of safety features that includes adaptive cruise control and lane-keeping assist. It also offers a spacious and modern cabin filled with high-quality materials.
- Acura MDX Features: The MDX elevates the luxury experience with a standard 12.3-inch infotainment display and a larger sound system. The MDX also offers more luxurious materials and finishes, especially in higher trims, enhancing the overall upscale feel.
Fuel Efficiency
Fuel efficiency is an essential consideration for many SUV buyers, and both Acura SUVs offer competitive figures.
- Acura RDX Fuel Efficiency: The RDX typically boasts 21 mpg in the city and 27 mpg on the highway,* thanks to its turbocharged 2.0-liter engine. This efficiency makes it an appealing choice for daily commutes and longer drives.
- Acura MDX Fuel Efficiency: The MDX, equipped with a 3.5-liter V6 engine, offers slightly lower efficiency, averaging around 19 mpg in the city and 26 mpg on the highway in FWD models.* While it's a bit less fuel-efficient than the RDX, its larger size and capability may justify the difference for many buyers.
Your Next Acura
Ultimately, the decision between the Acura RDX vs MDX comes down to your specific needs. If you're looking for a compact SUV with excellent maneuverability and fuel efficiency, the Acura RDX is an ideal choice. Its size and cargo space are sufficient for daily use while providing a luxurious ride.
Conversely, if you need more space for passengers and cargo, the Acura MDX is the clear winner. With its generous interior room and impressive cargo capacity, it's perfect for families or anyone who values comfort and versatility.
