With its tech-forward interior, sport-inspired design, and competitive price tag, it’s ideal for urban dwellers or first-time luxury buyers who want a bold, modern experience without overextending their budget.

▹ The 2025 RDX remains a cornerstone of Acura’s SUV range, offering more space, significantly more power, and a broader array of premium features. It delivers a refined yet athletic driving experience and caters to those who prioritize interior versatility, highway performance, and upscale comfort. While it starts at a slightly higher MSRP than the ADX, the RDX justifies the added investment with greater room, stronger performance, and more robust feature potential—especially in higher trims that can surpass the ADX’s top-tier offerings.

With MSRP pricing of $44,000 for the ADX A‑Spec Advance AWD* and $44,700 for the RDX Base*, the decision may come down to what you value most in your next SUV:

If affordability is a top priority, the ADX stands out as the more economical choice—perfect for buyers who want to step into the Acura brand without stretching their budget.

FULL DISCUSSION:

When comparing the 2025 Acura ADX A‑Spec Advance AWD and the 2025 Acura RDX (Base Trim), several key differences emerge in terms of performance, drivetrain, transmission, and fuel economy. These distinctions highlight the ADX’s focus on efficiency and modern compact engineering versus the RDX’s emphasis on power and traditional performance.
Under the hood, the ADX is powered by a 1.5-liter turbocharged VTEC inline-4 engine, which produces 190 horsepower at 6000 rpm and 179 lb-ft of torque between 1700 and 5000 rpm. In contrast, the RDX is equipped with a larger and more powerful 2.0-liter turbocharged VTEC inline-4 engine that delivers a robust 272 horsepower at 6500 rpm and 280 lb-ft of torque from 1600 to 4500 rpm. Clearly, the RDX has a significant edge in raw power and torque, which would translate to stronger acceleration and more dynamic highway performance.
The transmission systems further differentiate these models. The ADX features a Continuously Variable Transmission (CVT) with paddle shifters, designed for smoother transitions and fuel efficiency. The RDX, on the other hand, utilizes a 10-speed automatic transmission with paddle shifters, offering more defined gear shifts and performance-oriented driving dynamics. Drivers who prioritize precision and responsiveness might favor the RDX’s traditional automatic setup, while those seeking a more seamless and efficient ride could appreciate the ADX’s CVT.
Both vehicles come standard with all-wheel drive, but the systems differ in complexity and capability. The ADX employs an AWD with Intelligent Control system, suitable for most road conditions and offering balanced traction. The RDX features Acura’s more advanced SH-AWD® (Super Handling All-Wheel Drive), which enhances handling by actively distributing torque between the rear wheels, providing superior grip and stability during aggressive cornering or adverse conditions.
Fuel efficiency is another area where the ADX stands out. It achieves an estimated 25 mpg in the city and 30 mpg on the highway*, making it a better choice for drivers looking to minimize fuel costs. The RDX’s larger engine and performance-focused setup yield slightly lower fuel economy, rated at 21 mpg city and 27 mpg highway*. This tradeoff reflects the RDX’s more powerful drivetrain and larger displacement engine.
IN SUMMARY – the 2025 Acura ADX A‑Spec Advance AWD prioritizes fuel economy and everyday efficiency, making it ideal for urban driving and daily commutes. The 2025 RDX Base, while less efficient, offers a more commanding driving experience with greater power and advanced handling technology, catering to drivers who value performance and dynamic capability.

TL;DR:

The RDX’s larger dimensions—longer wheelbase, wider stance, and higher ground clearance—make it better suited for comfort, stability, and mild off-road capability. The ADX, on the other hand, embraces a smaller, lower-slung profile that enhances agility and urban maneuverability. If you value a commanding presence and greater utility, the RDX wins; if nimble city driving is your priority, the ADX is the smarter fit.

FULL DISCUSSION:

When comparing the exterior dimensions and proportions of the 2025 Acura ADX and the 2025 Acura RDX, it becomes clear that the RDX is the larger and more commanding presence of the two. This size difference reinforces each vehicle’s intended purpose and target audience, with the ADX designed for urban maneuverability and efficiency, while the RDX offers more space and a bolder footprint for drivers prioritizing interior room and versatility.

Starting with the wheelbase, the ADX sits on a 104.5-inch platform, whereas the RDX stretches to 108.3 inches. The longer wheelbase of the RDX contributes to a more spacious cabin, particularly for rear-seat passengers, and typically offers a more stable, comfortable ride. Similarly, the overall length of the RDX is slightly greater at 187.4 inches, compared to the ADX’s 185.8 inches. While the difference is modest, it still adds to the RDX’s road presence and cargo volume potential.

In terms of width, the RDX again surpasses the ADX, measuring 74.8 inches versus the ADX’s narrower 72.5 inches. This added width not only enhances the RDX’s stance and cabin comfort, especially for shoulder room, but also contributes to a more planted and stable driving feel. Track measurements reflect this as well—at the front and rear, the RDX features wider tracks (64.2 and 64.7 inches, respectively) compared to the ADX’s 62.6 and 63.2 inches. These differences support better handling dynamics in the RDX, particularly when cornering or navigating uneven terrain.

Height and ground clearance continue the trend, with the RDX standing taller at 65.7 inches and offering 8.2 inches of ground clearance. In contrast, the ADX is lower-slung at 63.8 inches in height and provides 7.3 inches of clearance. The RDX’s added height and clearance make it more adept at handling light off-road scenarios or rougher roads, and may also provide a higher driving position that some buyers prefer. Meanwhile, the lower height and clearance of the ADX contribute to better aerodynamics and easier entry and exit—benefits well-suited for city driving.

Overall, the RDX presents a larger and more robust design, optimized for comfort, stability, and light utility. The ADX, by comparison, is more compact and agile, designed to navigate tighter city spaces with ease while maintaining a stylish and efficient profile.

TL;DR:

The RDX provides a more spacious and arguably more versatile interior, a key selling point for drivers prioritizing passenger comfort and cargo capacity. The ADX, with its sportier proportions, sacrifices a bit of interior volume in favor of a lower, more athletic stance that contributes to improved handling dynamics. Consequently, if maximum interior space and cargo versatility are critical to your lifestyle, the RDX emerges as the clear winner in this category.

FULL DISCUSSION:

When evaluating the interior space of the 2025 Acura ADX A‑Spec Advance AWD and the 2025 Acura RDX Base, the RDX clearly asserts its position as the more spacious and accommodating SUV. Both vehicles offer seating for five passengers, but the RDX provides noticeably more room across nearly every key measurement, making it the preferred option for those who prioritize interior comfort and cargo versatility.

The total passenger volume is where the contrast begins, with the ADX offering 97.3 cubic feet compared to the RDX’s more generous 104.0 cubic feet. This added space in the RDX translates to greater comfort for both front and rear passengers, especially on longer drives. Headroom is slightly more generous in the RDX as well, offering 40.0 inches in the front and 38.0 inches in the rear, versus the ADX’s 38.5 and 36.8 inches, respectively. While the difference might not be immediately noticeable for shorter passengers, taller individuals will likely appreciate the added vertical space in the RDX.

Legroom between the two is fairly close, but the RDX edges ahead with 42.0 inches in the front and 38.0 inches in the rear, narrowly surpassing the ADX’s 41.9 inches up front and 37.7 inches in back. Similarly, the RDX boasts more generous hip room—55.0 inches in the front and 50.0 in the rear—compared to the ADX’s 54.0 and 47.4 inches. These small but cumulative differences can significantly enhance occupant comfort, especially when carrying adult passengers in the rear seat.

Shoulder room follows the same pattern, with the RDX providing a wider feel inside the cabin. It offers 60.0 inches of shoulder room in the front and 57.0 inches in the rear, notably wider than the ADX’s 56.6 and 55.2 inches. This additional space gives occupants more personal room and helps prevent that cramped feeling, especially on road trips or when the vehicle is fully loaded.

Cargo capacity is another area where the RDX outperforms the ADX. The ADX delivers 23.2 cubic feet of trunk space behind the second row, while the RDX offers a larger range, between 29.5 and 31.1 cubic feet depending on the configuration. With the rear seats folded, the ADX expands to 53.9 cubic feet of space—adequate for a compact SUV—but still falls short of the RDX’s expanded cargo range of 58.9 to 79.8 cubic feet. This considerable difference makes the RDX far more practical for carrying larger items, weekend gear, or bulky luggage.

In summary, while both the ADX and RDX seat the same number of passengers, the RDX offers a noticeably more spacious and versatile interior. It caters well to families or individuals who regularly transport passengers and cargo. The ADX, while slightly more compact, still offers a comfortable experience and efficient use of space, making it a strong contender for urban dwellers or solo drivers who value agility without completely sacrificing interior comfort.

TL;DR:

The ADX delivers a tech-forward, sporty design with modern displays and integrated Google services, appealing to drivers who value sleek styling and digital convenience. The RDX Base offers a more traditional luxury approach with wider upgrade potential. While the ADX comes well-equipped, higher trims of the RDX can match or exceed it in technology, comfort, and premium features—making the RDX a more flexible and upscale choice for those seeking long-term value and customization.

FULL DISCUSSION:

When comparing the 2025 Acura ADX A‑Spec Advance AWD and the 2025 Acura RDX Base Trim in terms of features and exterior styling, it’s evident that both vehicles cater to different priorities—one emphasizing modern sportiness and tech-forward integration, the other focusing on refined comfort and upscale design rooted in traditional Acura styling. While they share certain core technologies, their presentations and available enhancements set them apart in meaningful ways.

Starting with the displays, the ADX takes a more modern, touchscreen-forward approach. It features a 9-inch infotainment touchscreen complemented by a 10.2-inch digital instrument cluster, which delivers performance data directly in front of the driver. The RDX, by contrast, uses a 10.2-inch HD center display paired with a 7-inch multi-information display, operated via Acura’s True Touchpad Interface. While the RDX offers a larger infotainment screen, its interface may feel less intuitive to those who prefer the immediacy of a touchscreen. The ADX, meanwhile, leans into a digital-native experience, reinforcing its appeal to tech-savvy drivers.

Both models come with wireless Apple CarPlay and Android Auto integration, along with AcuraLink for remote access and vehicle management. However, the ADX also incorporates integrated Google services—an increasingly valuable feature that brings voice control, navigation, and Google apps into the car without the need for a connected smartphone. The RDX adds built-in Wi‑Fi hotspot functionality, which may appeal more to passengers who want always-on internet access for streaming or productivity on the go.

In terms of audio, the ADX includes a premium 8-speaker system as standard, offering a well-rounded audio experience without requiring upgrades. The RDX, while equipped with a more basic standard sound system, allows for enhanced audio through optional packages. It’s worth noting that higher trims of the RDX can be equipped with advanced audio systems and premium features that meet or exceed what’s found in the top-trim ADX, giving buyers a broader range of options depending on their preferences and budget.

Driver assistance technology is robust in both models. The ADX offers a comprehensive suite of active safety features, including Forward Collision Warning (FCW), Collision Mitigation Braking System (CMBS), Lane Departure Warning (LDW), Lane Keeping Assist System (LKAS), Road Departure Mitigation (RDM), Adaptive Cruise Control, and Traffic Sign Recognition. The RDX mirrors this advanced set of safety technologies but allows for further enhancement through add-on packages—such as a surround-view camera system—offering an extra level of convenience and situational awareness for those who choose to upgrade. Again, in upper trims, the RDX can surpass even the ADX’s top configuration in safety tech and driver-assist innovation.

When it comes to exterior styling, the ADX leans into an aggressive, sport-oriented aesthetic. Its standout features include 19-inch Berlina Black wheels, rain-sensing wipers, and a power lift tailgate—all enhancing its modern, performance-driven image. The RDX takes a more traditional approach with classic Acura design language, including signature Jewel Eye LED headlights, a panoramic roof, and heated side mirrors. It emphasizes elegance and broad appeal rather than edge.

Interior styling further reflects each vehicle’s personality. The ADX features a sport-oriented cockpit with bolstered seats and ambient LED lighting, creating a dynamic and youthful driving atmosphere. In contrast, the RDX highlights comfort and spaciousness with premium materials and a refined cabin design. Features like dual-zone climate control add to the overall sense of luxury and daily usability. And again, while the RDX Base offers a more subdued experience compared to the top-trim ADX, buyers should keep in mind that higher trims of the RDX offer upscale interior finishes, technology, and comfort features that match or exceed anything available in the ADX lineup.

In conclusion, the 2025 Acura ADX A‑Spec Advance AWD is geared toward drivers who prioritize bold styling, digital integration, and sporty design, especially appealing to a younger or more tech-centric audience. The 2025 RDX Base Trim, while more restrained at entry level, provides a strong foundation of premium features and comfort—with the added benefit of upgrade paths that allow it to match or surpass the ADX in technology, luxury, and performance as you move up the trim ladder.

After evaluating every major category—from engine performance and drivetrain technology to dimensions, interior space, fuel economy, and tech features—it’s clear that both the 2025 Acura ADX A‑Spec Advance AWD and the 2025 Acura RDX Base Trim are thoughtfully engineered vehicles, each serving distinct roles in Acura’s SUV lineup. Which one is right for you ultimately depends on your driving habits, lifestyle needs, and appetite for performance or luxury.

SUMMARY: 2025 Acura ADX A‑Spec Advance AWD

The ADX A‑Spec Advance AWD marks Acura’s newest entry into the compact SUV segment, and it positions itself as a sporty, efficient, and tech-savvy alternative for modern drivers. Designed with urban environments and younger buyers in mind, it offers a sleek exterior, smaller footprint, and high-efficiency powertrain. Its 1.5-liter turbocharged engine, paired with a CVT and standard all-wheel drive, prioritizes everyday drivability, comfort, and strong fuel economy—earning up to 30 mpg on the highway. The ADX doesn’t try to overpower or outmuscle; instead, it plays to its strengths: agility, technology, and overall ease of use.
Inside, the ADX offers a modern, minimalist cabin with a digital-first experience. Features like a 9-inch touchscreen, 10.2-inch digital instrument cluster, integrated Google services, and wireless Apple CarPlay/Android Auto make it a standout for those who want seamless tech in their daily commute. With 23.2 cubic feet of cargo space and a total passenger volume of 97.3 cubic feet, the ADX provides respectable utility—though its lower roofline and compact design place it behind the RDX in terms of raw space and comfort.

SUMMARY: 2025 Acura RDX Base

By comparison, the 2025 Acura RDX represents the more traditional premium SUV experience. It brings a larger footprint, stronger performance, and more flexibility for those who need extra room or plan to travel frequently with passengers and cargo. Its 2.0-liter turbocharged engine produces 272 horsepower—an 82-hp advantage over the ADX—and its 10-speed automatic transmission delivers crisp, responsive shifts. The standard SH-AWD® system adds an edge in performance handling and cornering confidence that driving enthusiasts will appreciate.
Where the RDX really stretches ahead is in space and scalability. With over 104 cubic feet of passenger volume and up to 79.8 cubic feet of cargo space with the rear seats folded, it’s a top pick for families, road-trippers, and professionals who need room to spread out or haul gear. Even in its base trim, the RDX offers upscale design touches, dual-zone climate control, and a comfortable, quiet cabin. But it’s important to emphasize that higher RDX trims significantly elevate the experience, offering advanced driver assistance, surround-view cameras, premium ELS Studio audio systems, and upscale interior materials that can surpass the feature set of the top-trim ADX.

FINAL THOUGHTS

Stylistically, the ADX leans into a youthful, athletic vibe with black accents and bold proportions, while the RDX presents a more refined, timeless luxury aesthetic. Each model is beautifully executed in its own right—it just depends on whether your style leans more toward edgy and contemporary or classic and elegant.
Ultimately, the ADX is best suited for buyers seeking a smart, affordable entry into the luxury SUV market—especially those who prioritize city-friendly sizing, fuel efficiency, and leading-edge tech. It offers a high-value package without compromise on quality. Meanwhile, the RDX is for drivers who want more room, more muscle, and more room to grow, whether through upgraded trims or simply more space to carry what life demands. It remains one of the most well-rounded vehicles in its class.
In short: If you want the most for your dollar right now, the ADX delivers a top-tier experience at a competitive price. If you’re planning for more power, space, and long-term luxury, the RDX—particularly in higher trims—is the SUV that can grow with you.
