2021 Acura RDX vs 2022 Lexus RX

The 2021 Acura RDX, especially with the optional A-Spec Package, had a visually appealing design. Its subtle styling changes, such as the inclusion of blacked-out trim and performance design cues, communicated a sporty appeal without exaggeration. Acura maintained a balance by avoiding excessive off-road elements like oversized skid plates and bulging fender flares, aligning with its primary function as a daily driver and road trip companion. The RDX's exterior was completed with sport seats featuring simulated suede inserts, special piping, a sport steering wheel, a black headliner, and other sport-focused elements. However, the gauge cluster was one drawback, as its red markings on a brushed silver background were difficult to read during daylight.

In contrast, the 2022 Lexus RX presented a modern and sporty design, particularly noticeable in the F Sport trim. This model had aggressive styling with razor-sharp character lines and angular features, creating a distinct and eye-catching look. New colors such as Cloudburst Gray and Iridium were added to the palette for 2022, and F Sport models introduced a striking Grecian Water hue. The F Sport trim also brought enhancements like 20-inch wheels, dark window trimming, and a unique front fascia with larger air intakes. Inside, the RX maintained a luxurious atmosphere with quality materials and added sporty touches in the F Sport model. However, the center stack appeared a bit dated, and the comfort of the NuLuxe seats in the F Sport trim was less than ideal, lacking cushioning and lumbar support adjustment.

The 2021 Acura RDX was equipped with a turbocharged 2.0-liter four-cylinder engine producing 272 horsepower at 6,500 rpm and 280 pound-feet of torque from 1,600 to 4,500 rpm. Despite the performance-oriented A-Spec Package, the engine output remained consistent across all models. A 10-speed automatic transmission with paddle shifters was standard, and the SH-AWD system was a worthwhile addition, significantly enhancing handling. Drivers could select from various driving modes, including Snow, Comfort, Sport, and Sport+, via the Integrated Dynamics System. This setup adjusted powertrain and steering responses, and in models with the Advance Package, the adaptive-damping suspension firmness.

However, it was observed that the A-Spec model exhibited too much body motion on uneven roads, lacking the adaptive dampers of the Advance Package. Furthermore, the 10-speed automatic transmission didn’t match revs, which could have improved the driving experience. Despite these drawbacks, the RDX excelled in terms of torque delivery, steering precision, and braking, making it a rewarding drive, especially in Sport+ mode.

The 2022 Lexus RX 350 came with a 3.5-liter V6 engine producing 295 horsepower and 267 pound-feet of torque, while the hybrid RX 450h added electric motors for a combined 308 horsepower. Both powertrains used an eight-speed automatic transmission. The RX's performance, particularly with the F Sport trim, was underwhelming. The engine produced more of a hum than a growl, and acceleration was lackluster. The F Sport Handling package included performance dampers, an adaptive variable suspension, a sound generator, and various driving modes like Sport and Sport+, which were intended to enhance driving dynamics. However, these modes did not significantly alter the driving experience, with Sport and Sport+ failing to deliver the anticipated sportiness.

In terms of comfort, the RX excelled, providing a smooth and quiet ride, ideal for long journeys. Fuel efficiency varied across models, with the RX 350 achieving 20 mpg city and 27 mpg highway. The hybrid RX 450h offered better fuel economy, averaging 30 mpg combined.

The 2021 Acura RDX, despite being classified as a compact SUV, offered exceptional passenger and cargo space. It had comfortable front seats with 12-way power adjustment, heating, and ventilation, which were ideal for spirited driving. However, the rear seats lacked leg support due to the design aimed at maximizing cargo space when folded. Storage space inside the cabin was also not optimal, with limited accessibility while driving.

Cargo volume in the RDX measured 29.5 cubic feet behind the rear seats, with additional storage compartments under the cargo floor, expanding practicality. With the rear seats folded, it offered 58.9 cubic feet of space, competitively ample but not class-leading. Acura's quoted maximum volume of 79.8 cubic feet, though generous, assumed an impractical packing method.

The 2022 Lexus RX offered 99.8 cubic feet of passenger volume in the standard two-row configuration, comfortably accommodating four adults, though the middle rear seat was less suitable for long trips. The three-row L models, while adding two additional seats, did not offer sufficient cargo space behind the third row, making them better suited for carrying groceries or small items. Cargo capacity in the standard two-row RX was 16 cubic feet behind the second row, expanding to 32.6 cubic feet with the seats folded. The three-row versions offered just 7.45 cubic feet with all seats upright, extending to 58.48 cubic feet with both back rows down, though the seats did not fold flat, and the loading height was high.

The 2021 Acura RDX introduced the True Touchpad Interface (TTI) infotainment system, which used a touchpad on the center console instead of a touchscreen. This system aimed to improve on Lexus' earlier approach by mirroring the screen, theoretically reducing distraction. However, drivers often found it unintuitive and distracting, especially compared to touchscreens, which have become universally familiar. The RDX came with other desirable tech features like physical stereo and climate controls, Apple CarPlay, Android Auto, and an impressive 16-speaker Acura/ELS Studio 3D premium audio system.

The 2022 Lexus RX featured an 8-inch touchscreen as standard, with an optional 12.3-inch display. Despite a refresh that moved the screens closer to the driver, it still had ergonomic issues. The touchscreen was placed in a recessed cove, creating accessibility challenges, especially for those with larger hands or longer nails. Voice commands and a touchpad were alternatives, but the touchpad was notoriously difficult to use, leading to frustration. The RX did offer a suite of tech features such as Android Auto, Apple CarPlay, wireless charging, Amazon Alexa, a WiFi hotspot, and premium audio systems.

The 2021 Acura RDX was equipped with the AcuraWatch suite of safety features, including adaptive cruise control, lane-keep assist, lane-departure warning, forward-collision warning, and automatic emergency braking. However, blind-spot warning and rear cross-traffic alert were only available with the Technology Package. The RDX earned high safety ratings, including a Top Safety Pick+ from the IIHS and a five-star overall rating from the NHTSA, though it received four stars in frontal-impact and rollover resistance tests.

The 2022 Lexus RX came standard with the Lexus Safety System 2.0+, which included adaptive cruise control with stop-and-go, lane-departure warning, road-sign recognition, lane-keeping assist, lane-tracing assist, a pre-collision system with cyclist- and pedestrian detection, and intelligent high beams. Additional features included blind-spot monitoring, rear cross-traffic alert, a head-up display, and Lexus Enform Safety Connect. The RX was a Top Safety Pick by the IIHS when equipped with optional triple-beam LED headlights but fell short of the Top Safety Pick+ rating. It received a four-star overall rating from the NHTSA, with five stars in side crash tests but fours in frontal crashes and rollover resistance.
