2025 Acura RDX vs MDX

2025 Acura RDX A‑Spec Advance Package vs. MDX SH‑AWD (Base Trim)

In this comprehensive comparison, we take a close look at two of Acura’s most prominent luxury SUVs for 2025: the RDX A-Spec® Advance Package and the MDX SH-AWD Base Trim. While they share many core Acura values—refined engineering, bold styling, and cutting-edge technology—these models are built with very different priorities in mind. Our goal is to provide a clear, data-driven breakdown of both vehicles, examining every key factor—from performance and drivetrain to interior space, technology, and pricing—based on official Acura specifications. Whether you’re deciding between athletic luxury and spacious utility, this guide will help you determine which SUV is the better fit for your driving needs and lifestyle.
As Acura continues to evolve its SUV lineup, the RDX and MDX remain at the heart of the brand’s identity. These vehicles represent two distinct takes on the modern luxury SUV—both sophisticated, both capable, but each tailored to a specific type of driver.

▹ The 2025 RDX A-Spec Advance is the most performance-oriented and tech-laden version of Acura’s popular two-row crossover. With aggressive styling, premium interior finishes, and the engaging performance of a turbocharged 2.0L engine paired with Acura’s SH-AWD® system, the RDX is designed for those who want sportiness without sacrificing comfort or everyday usability. It’s a top-tier compact SUV that delivers a bold, connected, and confident driving experience in a manageable size.

▹ The 2025 MDX SH-AWD Base Trim, meanwhile, serves as the entry point into Acura’s larger, three-row luxury SUV. While it starts at a slightly lower MSRP than the fully loaded RDX, the MDX offers significantly more passenger and cargo space, a smooth V6 engine, and an elegant, family-friendly interior layout. Its refined ride, advanced safety features, and commanding presence make it an ideal choice for families or drivers who need greater flexibility in a premium midsize SUV.

Though both the RDX and MDX fall under the Acura banner, they serve very different purposes. In the sections that follow, we’ll break down their differences and similarities in full detail to help you confidently choose the right Acura SUV for your journey.

Acura’s 2025 lineup showcases distinct personalities tailored to different driving needs. The 2025 Acura RDX equipped with the A‑Spec® Advance Package carries an MSRP of $54,450*, positioning it as a sporty, design–focused option for those who crave performance and a dynamic aesthetic. It features the top amenities of the RDX lineup.

 
When comparing pricing between the 2025 Acura RDX A-Spec® Advance Package and the 2025 Acura MDX SH-AWD Base Trim, it’s interesting to note how closely aligned they are in MSRP, despite targeting slightly different buyers and vehicle segments. The RDX A-Spec Advance, with its sportier persona, advanced technology, and high-end interior appointments, is priced at $54,450 MSRP*. This places it at the top end of the RDX lineup, appealing to drivers who want premium features in a two-row luxury SUV without stepping into a larger vehicle.

 
On the other hand, the MDX SH-AWD Base Trim is priced at $53,400 MSRP*, making it slightly more affordable than the fully loaded RDX. However, the MDX offers a larger footprint, three rows of seating, and greater passenger and cargo capacity, making it an ideal choice for families or those needing more interior flexibility. Despite being the entry-level MDX model, it still delivers strong value with Acura’s SH-AWD system, refined styling, and a well-appointed cabin.
Ultimately, while the RDX and MDX differ in purpose—one sportier and more compact, the other larger and more spacious—their similar price points give buyers an intriguing choice: premium performance and tech in a smaller package, or greater utility and room in a midsize SUV.

• Both models share the same transmission and SH-AWD system, so choose the MDX for added power and utility, and the RDX for its compact, responsive performance.

FULL DISCUSSION:

When comparing the 2025 Acura RDX A‑Spec Advance Package to the 2025 Acura MDX SH‑AWD (Base Trim), several notable distinctions emerge in terms of performance, engine design, torque delivery, and fuel efficiency. Though both models share Acura’s Super Handling All-Wheel Drive (SH-AWD) system and 10-speed automatic transmission with SportShift paddle shifters, they appeal to different types of drivers based on their powertrains and driving dynamics.

 
The 2025 RDX is powered by a 2.0-liter turbocharged 4-cylinder engine that produces 272 horsepower at 6500 rpm and 280 lb-ft of torque at a low 1600–4500 rpm range. This setup gives the RDX a strong balance of power and efficiency, with peak torque readily available at lower engine speeds—translating to responsive acceleration and confident passing power, especially in city and mid-range highway driving. The use of turbocharging enhances performance without sacrificing fuel economy, making the RDX a compelling choice for drivers who want a sporty, efficient compact luxury SUV.

 
In contrast, the 2025 MDX Base trim features a 3.5-liter naturally aspirated V6 engine that generates 290 horsepower at 6200 rpm and 267 lb-ft of torque at 4700 rpm. While it edges out the RDX in horsepower, it delivers slightly less torque and does so at higher revs. This results in a smoother, more linear power curve, which may be preferred by those who favor a traditional V6 driving feel. The MDX’s engine is tuned more for refinement and long-haul cruising than the punchy responsiveness of a turbocharged setup.

 
Both the RDX and MDX come standard with 10-speed automatic transmissions, which contribute to refined gear changes and optimized efficiency. Paired with Acura’s SH-AWD system, both models offer excellent traction and stability in a variety of conditions, enhancing confidence behind the wheel whether in rain, snow, or dry pavement. The RDX benefits from being a lighter and more compact vehicle, which complements its torque-rich engine and agile handling characteristics.

 
Fuel economy is another area where the RDX holds an advantage. It earns an EPA-estimated 21 mpg in the city and 26 mpg on the highway*, while the MDX delivers 19 mpg city and 25 mpg highway*. Though the difference is modest, it reflects the RDX’s more efficient powertrain and smaller footprint. For drivers who prioritize fuel efficiency without compromising on performance, the RDX presents a more economical option.

 
A key distinction between the two models lies in their towing capacity. The RDX is rated to tow up to 1,500 pounds*, which is suitable for light-duty hauling, such as towing small trailers or recreational equipment. In stark contrast, the MDX SH‑AWD is engineered for greater utility with a towing capacity of up to 5,000 pounds*, making it a more capable choice for those who require extra power for towing larger trailers, boats, or other heavy-duty gear.

 
In summary, the 2025 Acura RDX A‑Spec Advance delivers quick-access torque, better fuel efficiency, and a sportier driving profile thanks to its turbocharged 4‑cylinder engine, while the 2025 Acura MDX Base offers greater horsepower, a smooth V6 experience, and significantly higher towing capability. Both share Acura’s hallmark SH‑AWD system and refined 10‑speed transmission, catering to different performance expectations and lifestyle needs.

TL;DR:

• The MDX is significantly larger than the RDX in nearly every dimension, offering more space, a longer wheelbase, and a wider stance—ideal for families or those needing three-row capacity.
• The RDX, while smaller, has higher ground clearance and a more compact footprint, making it better for city driving and light off-road versatility.
• Choose the MDX for room and refinement; choose the RDX for agility and convenience.

FULL DISCUSSION:

When it comes to physical dimensions, the 2025 Acura MDX asserts itself as the larger, more commanding SUV in nearly every measurable way. This size difference highlights the MDX’s role as a three-row midsize SUV designed for families and passengers with space and comfort in mind, while the 2025 Acura RDX remains a more compact, agile option better suited to urban drivers or those who prioritize maneuverability.

 
Starting with the wheelbase, the MDX spans 113.8 inches, a full 5.5 inches longer than the RDX’s 108.3 inches. A longer wheelbase generally translates to improved ride comfort and more room for rear-seat passengers—particularly important in a three-row SUV like the MDX. This added length also contributes to the MDX’s more spacious cabin and more balanced ride dynamics on longer trips.

 
The overall length of the MDX is also substantially greater, measuring 198.4 inches compared to the RDX’s 187.4 inches. This not only enhances interior volume but also allows for a larger cargo area, making the MDX better equipped for road trips, growing families, or anyone needing to carry more gear regularly. The MDX is also wider, at 78.7 inches compared to the RDX’s 74.8 inches, which contributes to a roomier cabin—particularly noticeable in shoulder and hip room for passengers in all rows.

 
Looking at the track width (distance between wheels), the MDX once again takes the lead, measuring 67.7 inches front and rear, while the RDX comes in at 64.2 inches front / 64.7 inches rear. This wider track improves overall stability and handling, especially in a larger vehicle that may carry more passengers or cargo.

 
Interestingly, the RDX has the higher ground clearance, offering 8.2 inches compared to the MDX’s 7.3 inches. This gives the RDX a slight advantage in light off-road situations or when driving through snow, gravel, or uneven terrain. It also makes the RDX feel a bit more athletic in stance, complementing its smaller, sportier profile. The MDX, on the other hand, is slightly taller overall—67.9 inches versus the RDX’s 65.7 inches—providing a more commanding view of the road, though potentially making it a touch more difficult to enter or exit for some passengers.

 
In summary, the MDX’s larger footprint translates directly to more space, comfort, and presence, while the RDX’s smaller dimensions and greater ground clearance make it the more nimble and potentially adventurous of the two. Shoppers who need space and capability for a growing family will appreciate the MDX, while those looking for premium utility in a more manageable size may find the RDX to be ideal.

TL;DR:

• The MDX wins on space—it seats up to seven, offers more passenger volume, and provides greater cargo capacity when fully expanded.
• However, the RDX delivers excellent two-row comfort, more trunk space with seats upright, and a simpler layout for those who don’t need a third row.
• Choose the MDX for flexibility and family use; go with the RDX for a roomier five-seat experience with better day-to-day cargo practicality.

FULL DISCUSSION:

When comparing the 2025 Acura RDX A‑Spec Advance Package and the 2025 Acura MDX SH‑AWD Base Trim, one of the most significant differentiators is interior space and seating capacity. The MDX, as a three-row midsize SUV, is purpose-built for larger families and those who regularly transport multiple passengers. Meanwhile, the RDX, a two-row luxury crossover, focuses on maximizing comfort and utility for five occupants while maintaining a more compact, maneuverable footprint.

 
Starting with seating capacity, the RDX accommodates five passengers, while the MDX seats up to seven, thanks to its third-row seating. This makes the MDX the go-to choice for growing families or those who need to occasionally haul more people. However, the third row in the MDX does come with spatial trade-offs, as we’ll see in the measurements.

 
In terms of passenger volume, the difference is dramatic. The MDX offers 139.1 cubic feet of total passenger space, which is significantly more than the RDX’s 104.0 cubic feet. This added room enhances the comfort of second-row passengers in particular and allows for the inclusion of the third row, even if that row is best suited for children or smaller adults.

 
When we break down row-by-row dimensions, the RDX holds its own in the front two rows. It offers 40.0 inches of headroom in the front and 38.0 inches in the rear, slightly edging out the MDX’s 38.5 and 38.1 inches, respectively. The same trend continues with legroom, where the RDX offers 42.0 inches up front and 38.0 inches in the second row, nearly identical to the MDX’s 41.6 and 38.5 inches. However, the MDX introduces a third row with 29.1 inches of legroom and 36.2 inches of headroom, which, while more compact, gives it added seating flexibility.

 
The MDX pulls ahead in hip and shoulder room, especially in the first and second rows. It provides 59.3 inches of hip room up front and 57.8 inches in the second row, compared to the RDX’s 55.0 and 50.0 inches, respectively. Shoulder room also favors the MDX, with 61.9 inches front and 60.3 inches second row, compared to the RDX’s 60.0 and 57.0 inches. The third row in the MDX is naturally tighter, with 40.6 inches of hip room and 55.2 inches of shoulder room, but it still offers useful space for occasional passengers.

 
As for cargo capacity, each model offers unique strengths. Behind the second row, the RDX offers more usable trunk space, ranging from 29.5 to 31.1 cubic feet, compared to the MDX’s 16.3 to 18.1 cubic feet with all three rows in place. However, when you start folding down seats, the MDX’s larger size pays off. With the second and third rows folded flat, it delivers a spacious 71.4 to 95.0 cubic feet of cargo room, while the RDX tops out at 79.8 cubic feet with the rear seats down.

 
In short, the MDX offers greater total interior volume, more versatile seating, and superior cargo capacity—especially when hauling both passengers and luggage. The RDX, while smaller overall, holds its own in the first two rows and offers more trunk space when all seats are upright, making it an ideal luxury SUV for smaller families or couples who want room to stretch out without needing third-row accommodations.

TL;DR:

• The RDX delivers sportier styling, a richer sound system, and athletic interior design—ideal for drivers who want performance-oriented luxury and high-end tech in a compact package.
• The MDX offers more upscale refinement, enhanced digital displays, and added family-friendly tech like Wi-Fi hotspot capability and blind spot monitoring.
• Pick the RDX for bold, immersive driving; choose the MDX for elevated luxury and everyday versatility.

FULL DISCUSSION:

When comparing the 2025 Acura RDX A‑Spec Advance Package with the 2025 Acura MDX SH‑AWD Base Trim, both SUVs deliver the premium feel and cutting-edge technology expected of the Acura brand—but they take distinct approaches in terms of display technology, connectivity, audio, driver assistance, and design language. The RDX leans sportier and more tech-forward in its presentation, while the MDX offers a more refined, family-oriented luxury experience with broader feature scalability.

 
Display and Interface Technology show clear differences between the two. The RDX features a 10.2-inch HD dual-content center display paired with a 7-inch color multi-information display, navigated via Acura’s True Touchpad Interface. In contrast, the MDX elevates the experience with a 12.3-inch color touchscreen and the HD Precision Cockpit™ digital instrument cluster, giving it a more immersive and intuitive dashboard layout. For buyers looking for a larger and more modern interface, the MDX edges ahead in this category.

 
Both models offer a full suite of connectivity features, including AcuraLink® Connected Services, wireless Apple CarPlay®, wireless Android Auto™, and Amazon Alexa Built-In. However, the MDX adds Wi-Fi hotspot capability, which can be a deciding factor for families or commuters needing always-on internet access for devices and streaming. Both systems integrate smoothly with smartphones, voice assistants, and cloud-based services, though the MDX’s added connectivity makes it better suited for tech-heavy households.

 
When it comes to audio, the RDX clearly holds the advantage. It comes standard with the ELS Studio® 3D Premium Audio System, boasting 16 speakers and a rich, concert-like sound experience. The MDX, in contrast, is equipped with an 11-speaker Acura Audio System, which, while solid, doesn’t match the audio fidelity and spatial depth offered in the RDX. Music lovers and audiophiles will likely gravitate toward the RDX for its superior sound system.

 
Both SUVs are equipped with the comprehensive AcuraWatch™ driver assistance suite, which includes key safety technologies like Forward Collision Warning (FCW), Collision Mitigation Braking System™ (CMBS™), Lane Departure Warning (LDW), Lane Keeping Assist (LKAS), Road Departure Mitigation (RDM), and Adaptive Cruise Control with Low-Speed Follow. The MDX builds upon this with the addition of a Multi-View Rear Camera System and Blind Spot Information (BSI) as standard, giving it a slight edge in default safety visibility features.

 
In terms of exterior styling, both SUVs come well-equipped with Acura’s signature Jewel Eye® LED headlights, panoramic moonroofs, and power lift tailgates with hands-free access. The RDX adds sporty design elements such as 20” Berlina Black wheels, LED-illuminated Dragon Tail taillights, and LED puddle lights, enhancing its athletic curb appeal. It also includes rain-sensing wipers and a windshield de-icer—features that elevate convenience in colder climates. The MDX offers its own upscale touches, like Chicane™ LED daytime running lights, side mirror-integrated turn signals, and an acoustic laminate windshield for a quieter cabin—emphasizing refinement over flash.

 
Interior styling further underscores each model’s personality. The RDX features a sport-inspired cabin with perforated Milano leather and Ultrasuede® sport seats, a flat-bottom sport steering wheel, and dark brushed aluminum trim, creating a bold and energetic environment. Meanwhile, the MDX prioritizes luxury and space, with a refined three-row interior, leather-trimmed sport seats, ambient LED lighting, and a floating center console that emphasizes modern elegance and family-friendly ergonomics.

 
In conclusion, the RDX A‑Spec Advance is designed for drivers who value bold styling, immersive audio, and a sportier driving vibe, while the MDX SH‑AWD Base Trim is tailored for those who need more space and a calmer, more refined interior, with the added benefit of enhanced digital displays and safety visibility features. Both are exceptionally well-equipped, but they serve different lifestyles and expectations.

After an in-depth comparison of the 2025 Acura RDX A-Spec® Advance Package and the 2025 Acura MDX SH-AWD Base Trim, it’s clear that both SUVs deliver the luxury, performance, and innovation that define the Acura brand—yet they do so in distinct ways tailored to different drivers.

 
▹ The RDX A-Spec Advance shines as a sportier, more compact luxury SUV designed for those who prioritize dynamic driving, premium in-cabin tech, and everyday efficiency. With its turbocharged engine, standout ELS Studio® 3D audio system, higher fuel economy, and aggressive styling, the RDX is perfect for individuals or couples who want luxury and excitement without needing a third row or extra bulk. Its spacious two-row layout, high-quality materials, and driver-focused features make it a compelling choice for commuters and urban dwellers alike.

 
▹ The MDX SH-AWD Base is built with space, flexibility, and practicality in mind. Its naturally aspirated V6 provides smooth, confident performance, while its three-row seating and expansive interior volume make it an ideal fit for families, road-trippers, or anyone who regularly transports more than five passengers. Despite being the base trim, the MDX offers refined design elements, strong safety tech, and upscale appointments that rival higher-trim competitors. And with just a slightly lower MSRP than the top-tier RDX, it offers tremendous value for those seeking more interior room and seating versatility.

 
Ultimately, both the 2025 RDX and MDX deliver on Acura’s promise of precision-crafted performance, premium comfort, and thoughtful design. The RDX is best for drivers who want a nimble, performance-inspired SUV packed with advanced features in a sleek two-row format. The MDX, by contrast, is the more accommodating choice for larger households or those who want added utility without sacrificing luxury.

 
No matter which direction you go, Acura ensures you’ll enjoy a sophisticated, well-rounded vehicle built for real life—whether that means carving through mountain roads or cruising comfortably with the entire family.
