2021 Audi Q5 vs 2021 Acura RDX

The 2021 Acura RDX, particularly in the A-Spec trim, was a visually appealing SUV that managed to convey a sense of sportiness without resorting to excessive design elements. Its styling changes were subtle yet effective, avoiding the typical performance design cues and off-roading frippery, which made it clear that the RDX was designed for daily driving and road-tripping rather than rugged terrain. The A-Spec trim sat in the middle of the trim hierarchy, offering a sporty interior with features like front sport seats with simulated suede inserts, a sport steering wheel, and red ambient cabin lighting. However, the gauge cluster with red markings on a brushed silver background was difficult to read, except at night.

In contrast, the 2021 Audi Q5 presented a sharp and modern appearance, embodying the Audi design language while maintaining its unique character. The Q5 featured an expressive front with LED headlights and a prominent Singleframe grille, complemented by crisp body lines and bold taillights. The interior was equally classy and modern, with a focus on technology and an uncluttered design. The materials used were authentic and of high quality, with a 10.1-inch touchscreen positioned for optimal driver visibility. The Q5's interior was well-appointed, offering standard leather upholstery and a range of comfort features, making it a sophisticated choice for those seeking a premium crossover experience.

The 2021 Acura RDX was equipped with a 2.0-litre four-cylinder turbocharged engine, delivering 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 could direct up to 70% of engine output to the rear wheels, enhancing handling and driving enjoyment. The Integrated Dynamics System allowed drivers to select from Snow, Comfort, Sport, and Sport+ modes, adjusting powertrain response, steering effort, and suspension firmness. The A-Spec trim included exclusive 20-inch alloy wheels with performance all-season tires, although the lack of adaptive dampers resulted in some body motion on uneven roads.

The 2021 Audi Q5 PHEV took performance to another level with its plug-in hybrid setup, combining a 2.0-litre turbocharged engine with an electric motor for a total output of 362 horsepower and 373 pound-feet of torque. This setup allowed the Q5 PHEV to accelerate from 0 to 100 km/h in 5.3 seconds and achieve impressive fuel efficiency. The drivetrain featured a seven-speed S Tronic automatic transmission with full-time Quattro AWD, offering various driving modes, including electric-only and hybrid. The Q5's handling was characterized by a sporty suspension setup, minimal body roll, and powerful braking, making it a well-rounded performer.

The 2021 Acura RDX offered remarkable passenger and cargo space for a compact SUV, with comfortable front seats featuring 12-way power adjustment and heating. However, rear-seat comfort was compromised by a low and flat cushion, resulting in a lack of leg support. The cargo area provided 835 litres of space behind the rear seats and 1,668 litres with the seats folded, with additional storage compartments for organization. Despite its competitive cargo capacity, the RDX's storage solutions could have been more accessible.

The 2021 Audi Q5 PHEV excelled in smart packaging, with its battery pack located under the luggage compartment floor, preserving cargo space. It offered 710 litres of cargo space behind the second row and 1,503 litres with the seats folded. The second row provided ample legroom, headroom, and shoulder room, accommodating two adults comfortably. The front seats were supportive and adjustable, with available ventilation. The interior featured practical storage solutions, including cupholders and cubbies, enhancing its functionality.

The 2021 Acura RDX featured the True Touchpad Interface infotainment system, which used a touch-sensing pad on the centre console instead of a touchscreen. While it offered standard satellite radio, Bluetooth, and Wi-Fi tethering, the system required a learning curve and could be distracting. The A-Spec trim included a 16-speaker Acura/ELS Studio 3D premium audio system, delivering excellent sound quality. However, the TTI system's complexity and lack of a touchscreen option were notable drawbacks.

The 2021 Audi Q5 PHEV boasted Audi's latest MMI 10.1-inch touchscreen infotainment system, which was user-friendly and intuitive. The Audi Virtual Cockpit Plus provided a customizable 12.3-inch HD instrument cluster, enhancing the cabin's futuristic feel. The Q5 also featured a Bang & Olufsen 3D audio system with 19 speakers, offering exceptional sound quality. Wireless Apple CarPlay and wired Android Auto were included, ensuring seamless smartphone integration.

The 2021 Acura RDX came equipped with a suite of safety features, including adaptive cruise control, lane-keeping assist, 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, although it received four-star ratings for frontal-impact and rollover resistance.

The 2021 Audi Q5 PHEV had not been rated by the IIHS, but the gasoline model received top ratings in most categories. The Q5 included six airbags, electronic stability control, and a rearview camera. Available driver-assistance features included Audi Pre Sense front, adaptive cruise control, and traffic-sign recognition, enhancing its safety credentials.
