2021 Toyota 4Runner vs 2021 Acura RDX

The 2021 Acura RDX, particularly in the A-Spec trim, was a visually appealing SUV. Its design changes were subtle yet effective, conveying a sense of sportiness without overpromising on performance. Acura avoided giving the RDX an off-road appearance, focusing instead on its role as a daily driver and road-tripper. The A-Spec trim sat in the middle of the RDX's trim hierarchy, with a starting price of $50,305, and offered a sporty interior with features like front sport seats, a sport steering wheel, and red ambient lighting. However, the gauge cluster's red markings on a brushed silver background were difficult to read, except at night.

In contrast, the 2021 Toyota 4Runner had not seen a redesign in over a decade, yet its design aged well, maintaining a timeless and utilitarian look. Most versions adopted a bold and aggressive front, except for the chrome-adorned Limited trim. The 4Runner's two-box body with flared fenders and trapezoidal wheel arches emphasized its balanced proportions and utility. The 4Runner was available in various trims and packages, with prices ranging from $46,200 to $62,430. Its interior featured hard plastic materials, a simple dashboard with large knobs and buttons, and a focus on durability and ease of cleaning.

The 2021 Acura RDX was equipped with a 2.0-litre four-cylinder turbocharged engine producing 272 horsepower at 6,500 rpm and 280 pound-feet of torque from 1,600 to 4,500 rpm. It featured a 10-speed automatic transmission with paddle shifters and the torque-vectoring SH-AWD system, which improved handling by delivering up to 70% of engine output to the rear wheels. The RDX offered driving modes like Snow, Comfort, Sport, and Sport+, which adjusted powertrain response, steering effort, and suspension firmness. A-Spec models had exclusive 20-inch alloy wheels with performance all-season tires, enhancing handling. However, the lack of adaptive dampers and rev-matching in Sport modes was noted. Despite these, the RDX was praised for its broad torque curve, precise steering, and fade-resistant brakes.

The 2021 Toyota 4Runner, with its 4.0-litre V6 engine, delivered 270 horsepower at 5,600 rpm and 278 pound-feet of torque at 4,400 rpm. It had a five-speed automatic transmission and a part-time 4WD system. The 4Runner excelled off-road, thanks to features like A-Trac, a locking rear differential, Multi-Terrain Select, and Crawl Control. However, on pavement, it felt slow and clunky, with heavy steering and brakes. Its truck-like driving characteristics were part of its charm, but it required frequent fuel stops, averaging 14.0 L/100 km during testing.

The 2021 Acura RDX, though classified as a compact SUV, offered impressive passenger and cargo space. Its front seats were comfortable, with 12-way power adjustment and heating as standard. However, rear-seat comfort was compromised due to a low and flat cushion and excessive seatback recline. Cargo space measured 835 litres behind the rear seat and 1,668 litres with the seats folded, with additional storage compartments. Acura quoted a maximum cargo volume of 2,260 litres, but this was based on unrealistic loading conditions.

The 2021 Toyota 4Runner sat high off the ground, which could be challenging for shorter individuals. Once inside, it provided comfortable seating with ample legroom and good visibility. The back seat had air conditioning vents and USB ports, and the rear tailgate glass could be lowered for an open-air feel. Cargo space was generous, with up to 1,337 litres behind the back seat and 2,540 litres with the seats folded. The 4Runner's back bumper served as a convenient seating area for various activities.

The 2021 Acura RDX featured the True Touchpad Interface infotainment system, which used a touch-sensing pad on the centre console. While it improved upon Lexus's approach, it still required a learning curve and could be distracting. The RDX included standard satellite radio, Bluetooth, Wi-Fi tethering, and an available navigation system. The A-Spec trim came with a 16-speaker Acura/ELS Studio 3D premium audio system, delivering excellent sound quality.

The 2021 Toyota 4Runner's entry-level Trail grade had limited technology features. It included a windshield wiper de-icer and a cargo area power outlet. The standard 8-inch touchscreen infotainment system offered Bluetooth, Apple CarPlay, Android Auto, and SiriusXM satellite radio. Higher trims added a dynamic navigation system and Destination Assist services. The system's physical buttons and knobs were easy to use, even with gloves, and the software included off-road trail maps.

The 2021 Acura RDX came with a suite of safety features, including adaptive cruise control, lane-keeping assist, lane-departure warning, forward-collision warning, and automatic emergency braking. However, blind-spot warning and rear cross-traffic alert were only available on higher trims. The RDX earned a "Top Safety Pick+" rating from the IIHS and a five-star overall rating from the NHTSA, though it received four-star ratings for frontal-impact and rollover resistance.

The 2021 Toyota 4Runner featured Toyota Safety Sense P, which included adaptive cruise control, forward-collision warning, automatic emergency braking, lane departure warning, and automatic high-beam headlights. However, it lacked blind-spot warning and rear cross-traffic alert. The 4Runner received a three-star rollover resistance rating from the NHTSA and a "Good" roof crush strength rating from the IIHS. Its protection in small overlap frontal-impact collisions was rated as Marginal by the IIHS, reflecting its age.
