2021 BMW X7 vs 2020 Acura MDX

The 2020 Acura MDX presented its audience with a polished and sleek appearance without venturing into the territory of groundbreaking automotive design. It did not command attention in crowded parking lots or occasion special treatment from valets, but it fulfilled its role as an attractive and adequately stylish crossover SUV. Its distinct Jewel Eye headlights, an Acura signature, adorned the front of the vehicle with five LED elements per side, which offered both function and a sophisticated aesthetic. These headlights flanked a trapezoidal grille prominently featuring the Acura logo, creating an expressive front fascia.

For a three-row SUV, the MDX's design was impressively sleek and low-slung, with meticulously executed paint and chrome finishes, hallmarks of Acura’s dedication to quality. Inside, the vehicle exuded a modern and straightforward design ethos, avoiding the padding and stitching prevalent in many luxury interiors of its time. The center stack was particularly noteworthy, equipped with twin infotainment screens: a high-mounted 8.0-inch LED screen for navigation and the On Demand Multi-Use Display touchscreen.

In a world where luxury often correlated with excessive ornamentation, the MDX stood out for its simplicity, underpinned by high-quality materials and superior fit and finish. The vehicle felt robust and well-constructed, with knobs and switches that actuated with satisfying precision.

Conversely, the 2021 BMW X7 was all about making a strong impression. In a market brimming with luxury SUVs, the X7 stood out with its greater interior quality compared to rivals like the Cadillac Escalade and more prestige than the Infiniti QX80 or Lincoln Navigator. The X7 delivered a higher level of technological sophistication than a Lexus LX 570 and a significant visual presence to rival the Mercedes-Benz GLS-Class.

The BMW X7 was available in three versions, each escalating in both luxury and price. The xDrive40i, which started at $74,900, was our test vehicle and came well-equipped with 22-inch aluminum wheels, extended leather interiors, an Alcantara suede headliner, and more. The grille, a defining feature, sparked reactions; its large, kidney-shaped design fit the SUV’s considerable size and intent.

Inside, the X7 echoed the luxury and design language of its smaller sibling, the X5, but with added nuances that brought it closer to the pinnacle of BMW's SUV lineup. High-tech design and excellent material quality were the norm, with controls and technology that, although sophisticated, required some acclimation over time.

The 2020 Acura MDX offered two powertrain options. The first was a naturally-aspirated 3.5-liter V6 engine that produced 290 horsepower and 267 pound-feet of torque. This engine was mated to a nine-speed automatic transmission, with buyers having the choice between front-wheel drive and Acura’s Super-Handling All-Wheel Drive system (SH-AWD). The second option was for those who favored hybrid technology; the MDX Sport Hybrid combined a 3.0-liter V6 gasoline engine with three electric motors, delivering a total of 321 horsepower and 289 pound-feet of torque through a seven-speed dual-clutch automatic transmission.

The MDX with SH-AWD displayed impressive performance on various terrains, thanks to the system’s torque-vectoring capability. This feature redirected power to the outside rear wheel during cornering, enhancing handling and ensuring smooth, drama-free acceleration even from a standstill around corners. The four-wheel independent suspension added to the MDX’s comfort, efficiently absorbing road irregularities and providing a pleasant driving experience.

The 2021 BMW X7 took a different approach to performance, offering a turbocharged 3.0-liter inline six-cylinder engine in its xDrive40i variant. This engine, paired with an eight-speed sport automatic transmission and BMW’s rear-biased all-wheel-drive system, delivered 335 horsepower and 331 pound-feet of torque. The 2021 model incorporated BMW’s eBoost mild-hybrid technology, which included a 48-volt starter/generator and battery system that provided an “electric boost effect” for improved responsiveness.

Despite the intention to enhance fuel economy, the 2021 X7 xDrive40i saw a slight drop in EPA ratings compared to the 2020 model. Nevertheless, the X7 was capable of impressive acceleration, with BMW claiming a 0-60 mph time of 5.8 seconds. The X7's driving experience was generally smooth and serene, thanks to features like the Active Comfort Drive system and Dynamic Handling Package, which included air suspension and adaptive steering.

However, the X7’s considerable curb weight of nearly 5,400 pounds became noticeable on tighter, winding roads, where the SUV’s dynamics sometimes felt cumbersome. Still, its ability to handle high speeds effortlessly, combined with the brilliance of the eight-speed transmission, made it a formidable choice for luxury SUV enthusiasts.

In terms of interior space, the 2020 Acura MDX aimed to meet the functional needs of families. It featured sliding and reclining second-row seats, facilitating easier access to the third row and customizable legroom distribution. With 15.8 cubic feet of cargo space behind the third row, expanding to 43.4 cubic feet with the third row folded and 90.9 cubic feet with both rear rows down, the MDX offered ample cargo capacity for various needs. Additionally, it had numerous storage options, including a large glove box, a versatile center console, and door panel pockets.

Similarly, the 2021 BMW X7 provided a luxurious and accommodating interior, particularly with the optional Cold Weather Package, Luxury Seating Package, and premium Merino leather upholstery. The front seats were extremely comfortable, with heating features standard and even more warmth provided by the Cold Weather Package. Second-row passengers enjoyed similar levels of comfort, with available captain’s chairs and climate controls.

Notably, the X7’s third-row seats were suitable for adults, a rarity among three-row SUVs. The power-folding seats offered 48.6 cubic feet of cargo space when the third row was down, and a maximum of 90.4 cubic feet with the second row folded. While this was slightly less than the MDX, the X7’s overall interior layout was designed with luxury and convenience in mind.

The 2020 Acura MDX was well-equipped with technological features across its trim levels, grouped into comprehensive packages to simplify choices. The base model included Siri Eyes Free, Apple CarPlay, Android Auto, Bluetooth, and more. The Technology Package added navigation, advanced climate control, and a premium audio system, while the Advance Package introduced further enhancements like a surround-view camera and heated rear seats. For entertainment, the optional Entertainment Package included a rear DVD system and additional speakers.

The 2021 BMW X7, on the other hand, boasted BMW’s Live Cockpit Professional digital instrumentation paired with the iDrive 7.0 infotainment system. The dual 12.3-inch displays, combined with features like Android Auto, Apple CarPlay, and enhanced SiriusXM 360L, provided a robust infotainment experience. The system's natural voice recognition, though impressive, had some inconsistencies with gesture controls. The head-up display was a useful addition, although polarization of sunglasses could impact its visibility.

Safety was a strong focus for both vehicles. The 2020 Acura MDX came standard with AcuraWatch, a suite of advanced driver assistance systems that included adaptive cruise control, lane-keep assist, forward-collision warning, and more. The Technology Package added blind-spot monitoring, while the Advance Package included a head-up warning. The MDX’s safety credentials were backed by top ratings from the IIHS and a five-star overall rating from NHTSA.

The 2021 BMW X7 featured extensive safety technologies, many of which were standard, complemented by optional packages like the Driving Assistance Professional Package and the Parking Assistance Package. These packages added features such as evasive-steering assist, traffic-jam assist, semi-automated parking, and more. The effectiveness of these systems was generally impressive, providing a reassuring level of safety and convenience.
