2019 Acura RDX vs 2020 Lexus RX

The 2019 Acura RDX showcased a bold new exterior design, drawing inspiration from its larger sibling, the Acura MDX. The front end featured angular headlights flanking a broad, assertive grille, a significant improvement from the previous "shield" or "beak" grille. The RDX's more upright layout and rear end design aimed to increase cabin space, presenting a modern and sharp aesthetic. Inside, the RDX boasted soft-touch surfaces, unique stitching, and brushed aluminum accents, creating a luxurious feel. Standard features included 19-inch alloy wheels, LED lighting, a power liftgate, and a panoramic moonroof. The interior was well-equipped with leather upholstery, heated power seats, dual-zone climate control, and a 10.2-inch HD infotainment system with Apple CarPlay integration.

The 2020 Lexus RX received a significant refresh, enhancing its appeal in a competitive market. The exterior updates included standard 18-inch wheels, slimmer headlights, and L-shaped taillights, with optional triple-beam LED headlights. The grille was redesigned to align with Lexus cars, and new paint colors were introduced. The rear end featured a new shape with dual exhaust, a rear diffuser, and updated reflectors. Inside, the RX maintained its reputation for a well-appointed cabin with various interior color and material options. The F Sport package added unique styling elements and performance dampers. The RX's interior was comfortable and practical, though the center stack design appeared dated compared to newer models.

The 2019 Acura RDX was powered by a turbocharged 2.0-liter inline 4-cylinder engine, producing 272 horsepower and 280 pound-feet of torque. This engine was paired with a 10-speed automatic transmission, available in front-wheel drive or Acura's Super-Handling All-Wheel Drive (SH-AWD) system. SH-AWD could divert up to 70% of torque to the rear wheels, enhancing performance in various driving conditions. The RDX offered an Integrated Dynamics System with Comfort, Snow, Sport, and Sport+ modes, adjusting throttle response, shift mapping, and steering feel. Fuel economy for the front-wheel drive model was 22 mpg city, 28 highway, and 24 combined, while the AWD version achieved 21/27/23 mpg.

The 2020 Lexus RX 350 featured a 3.5-liter V6 engine with 295 horsepower and 267 pound-feet of torque, paired with an eight-speed automatic transmission. The RX 350L variant had slightly lower power output. A hybrid version, the RX 450h, combined the V6 with an electric motor, producing 308 horsepower and 247 pound-feet of torque. The RX 450hL had a similar setup but with different power outputs. The RX offered various drive modes, including Normal, Eco, Sport, and EV mode for hybrids. Fuel economy for the RX 350 was 23 mpg combined, while the RX 450h achieved 30 mpg combined. The F Sport package added adaptive variable suspension and other performance enhancements.

The 2019 Acura RDX provided 29.5 cubic feet of cargo space with the rear seats up, increasing by 3 cubic feet from the previous model. With the rear seats folded, cargo capacity was 58.9 cubic feet. The interior was spacious, with ample head- and legroom for both front and rear passengers. The RDX featured numerous storage options, including a floating center stack design with a tray below, power and USB ports, and a conventional center console with a cupholder tray. All four doors had room for multiple water bottles, and the rear seat included a center armrest with cupholders.

The 2020 Lexus RX's interior was comfortable but not as stylish as its German competitors. The two-row RX model accommodated four adults comfortably, while the three-row RX-L's third row was best suited for small children or pets. The cabin was wide and tall, with comfortable front seats and good outward visibility. However, the A-pillar could obstruct the driver's view of curbs and corners. The RX's cargo area was smaller than its rivals, with a high load floor compromising space. The RX 350L and 450hL had even less cargo space compared to competitors like the Lincoln Aviator. A hands-free liftgate was available on RX 350 and 450h models and standard on RX-L versions.

The 2019 Acura RDX came standard with the True Touchpad infotainment system, replacing the previous two-screen setup. The high-definition screen was visually appealing, but the touchpad system had a steep learning curve. Simple tasks like changing the radio station required multiple steps, and saving presets was cumbersome. Apple CarPlay integration was available, but navigating within CarPlay was also challenging. Despite its flaws, the system was an improvement over the previous version.

The 2020 Lexus RX's infotainment system was often criticized, but improvements were made for the 2020 model. The standard 8.0-inch display and available 12.3-inch touchscreen were moved closer to the driver. The system remained difficult to navigate, but Apple CarPlay integration provided a workaround. The RX also offered Amazon Alexa, Android Auto, and other connectivity options. The touchpad system was more responsive, and the RX included six USB ports. The standard 12-speaker audio system was adequate, with an optional 15-speaker Mark Levinson system available.

The 2019 Acura RDX came standard with a reversing camera, tire pressure monitoring, traction control, and a full array of airbags. The AcuraWatch suite included forward-collision warning, forward-collision avoidance, lane-departure warning, road-departure warning, and lane-keeping assist. The Technology Package added parking sensors and blind-spot monitoring, while the Advance trim included a head-up warning system.

The 2020 Lexus RX featured the Lexus Safety System+ 2.0, which included adaptive cruise control, automatic high beams, and blind-spot monitoring. The 2020 model added daytime bicyclist detection, low-light pedestrian detection, road-sign assist, and lane-tracing assist. Lexus Enform Safety Connect and Service Connect were included, though connectivity issues were noted during testing. The RX received good safety ratings from the IIHS and NHTSA.
