2021 Acura RDX vs 2021 Kia Sorento

The 2021 Acura RDX, especially with the A-Spec Package, presented a sleek and sporty appearance without excessive embellishments. Its design changes were subtle yet effective, conveying a sense of sportiness without overpromising on performance. Acura avoided giving the RDX an off-road look, focusing instead on its role as a daily driver and road-tripper. The A-Spec trim, positioned in the middle of the lineup, offered a range of features, including a sporty interior with simulated suede inserts, a sport steering wheel, and unique gauges. However, the red markings on the gauge cluster were difficult to read, except at night.

In contrast, the 2021 Kia Sorento marked a significant departure from its predecessor's design, adopting a more athletic and muscular silhouette. The SX Prestige trim with the X-Line package added roof rails and a shark fin antenna, enhancing its outdoor-ready appearance. The Sorento's front featured an expansive tiger-nose grille and distinctive headlights, while the rear showcased vertical taillights. Inside, the Sorento offered high-value features, including heated mirrors, Apple CarPlay, and Android Auto. The interior was comfortable, with ample legroom in the front and second rows, although the third row was tight for adults.

The 2021 Acura RDX was powered by a turbocharged 2.0-liter four-cylinder engine, delivering 272 horsepower and 280 lb-ft of torque. It featured a 10-speed automatic transmission with paddle shifters and offered the option of Acura's Super Handling All-Wheel Drive (SH-AWD) system. The SH-AWD system improved handling by distributing power to the rear wheels, enhancing the driving experience. The RDX's Integrated Dynamics System allowed drivers to choose between different driving modes, adjusting powertrain response and steering effort. The A-Spec trim came with exclusive 20-inch alloy wheels and performance tires, contributing to its sporty feel.

The 2021 Kia Sorento offered a range of powertrains, with the standout being the turbocharged 2.5-liter four-cylinder engine producing 281 horsepower and 311 lb-ft of torque. Paired with an eight-speed dual-clutch transmission and all-wheel drive, it provided ample power for highway driving. The Sorento's AWD system featured torque vectoring and a center-locking differential for improved traction. The X-Line package added ride height and 20-inch wheels, enhancing its off-road capability. The Sorento's drive modes, including Eco, Normal, and Sport, allowed for varied driving experiences, although the vehicle's weight resulted in some body lean during cornering.

The 2021 Acura RDX, despite being classified as a compact SUV, offered impressive passenger and cargo space. The front seats were comfortable and adjustable, while the rear seats compromised leg support for cargo space. The RDX provided 29.5 cubic feet of cargo space behind the rear seats, expandable to 58.9 cubic feet with the seats folded. Additional storage compartments were available under the cargo floor. However, the rear seat design affected passenger comfort, and storage space could be improved.

The 2021 Kia Sorento, a three-row SUV, was best suited as a four-seater in its upper trims due to the tight third row. The second-row captain's chairs were comfortable, and the front and rear seats offered ample legroom. Cargo space was limited behind the third row, but folding the seats increased capacity to 75.5 cubic feet. The Sorento featured convenient storage options, including a phone slot with wireless charging, cupholders, and door pockets. While not as spacious as larger SUVs, the Sorento's cargo volume was competitive for its class.

The 2021 Acura RDX featured the True Touchpad Interface (TTI) infotainment system, which used a touchpad on the center console instead of a touchscreen. While an improvement over similar systems, it required a learning curve and could be distracting. The RDX offered physical controls for stereo and climate functions, along with smartphone integration and voice recognition technology. The A-Spec trim included a premium audio system, enhancing the overall experience.

The 2021 Kia Sorento offered an 8-inch touchscreen on lower trims and a 10.25-inch screen on higher trims. The larger screen required a physical connection for smartphone projection, limiting its usability. The Sorento provided ample USB ports but lacked USB-C options. The optional Bose stereo system was decent but not exceptional. The navigation system needed improvement, but most drivers would rely on smartphone integration for navigation.

The 2021 Acura RDX came equipped with AcuraWatch, a suite of safety features including adaptive cruise control, lane-keep assist, and automatic emergency braking. However, blind-spot warning and rear cross-traffic alert were only available with the Technology Package. The RDX received top safety ratings from the IIHS and NHTSA, although it earned four stars in frontal-impact and rollover tests.

The 2021 Kia Sorento offered a comprehensive array of standard safety features, including automatic emergency braking, lane-keeping assist, and adaptive cruise control. The Sorento's safety systems generally performed well, although the lane-keeping assist could be overly active. The Sorento received a four-star overall rating from the NHTSA and a Top Safety Pick designation from the IIHS, with higher trims earning better headlight ratings.
