2021 BMW X7 vs 2021 INFINITI QX80

The 2021 BMW X7 was a standout in the luxury SUV segment, often seen navigating the bustling streets of metropolitan Los Angeles. It was known for its superior interior quality, surpassing that of the Cadillac Escalade, and offered more prestige than the INFINITI QX80 or Lincoln Navigator. The X7 boasted advanced technological features that outshone the Lexus LX 570 and had a commanding visual presence that rivaled the Mercedes-Benz GLS-Class. Despite its impressive attributes, the X7's appeal was subjective, as personal preference played a significant role in this segment.

The X7 was available in three versions, with the xDrive40i starting at $74,900, the M50i at $99,800, and the Alpina BX7 at $141,300. The test vehicle, an X7 xDrive40i, was equipped with 22-inch aluminum wheels, premium leather, and a trailer hitch, among other features, bringing its price to $91,745. The X7's design was characterized by its large grille, which was fitting for its size, and its styling was both traditional and glamorous, securing its place at the top of BMW's SUV lineup. Inside, the X7 shared similarities with the X5, offering high-tech design and quality materials, though some quirks required getting used to.

The 2021 INFINITI QX80, on the other hand, combined elements from the Nissan Armada and Infiniti's own styling cues. Its body-on-frame construction was a nod to traditional SUV design, offering a robust build that was evident in its profile and rear window curves. The QX80's front end was distinctly Infiniti, featuring a grille and headlight design that gave it an assertive yet not overly aggressive look. Standard LED lighting and a choice of wheel sizes added to its appeal.

Inside, the QX80's design was reminiscent of the Armada, with Infiniti adding luxury touches like wood trim and leather upholstery. However, the interior still bore a strong resemblance to its Nissan counterpart, with features like a foot-operated parking brake detracting from its luxury status. While the interior was comfortable and luxurious, it lacked the exclusivity some buyers sought. The QX80's design was functional, but those seeking a more distinctive luxury experience might have found it lacking.

The 2021 BMW X7 xDrive40i was powered by a turbocharged 3.0-liter inline six-cylinder engine, delivering 335 horsepower and 331 lb-ft of torque. This engine was paired with an eight-speed sport automatic transmission and BMW's xDrive AWD system. The X7 featured eBoost mild-hybrid technology, which included a 48-volt starter/generator and battery, enhancing fuel efficiency and responsiveness. Despite these advancements, the X7's fuel economy ratings were slightly lower than the previous year, with 19 mpg in the city, 24 mpg on the highway, and 21 mpg combined.

The X7's performance was characterized by its smooth and powerful acceleration, reaching 60 mph in 5.8 seconds. The SUV's handling was aided by the Dynamic Handling Package, which included features like Active Comfort Drive and Integral Active Steering. However, the X7's size and weight were noticeable, especially on winding roads, where it exhibited some body roll. Despite this, the X7 provided a comfortable and serene driving experience, with excellent braking performance from the M Sport brakes.

The 2021 INFINITI QX80 was equipped with a 5.6-liter V8 engine, producing 400 horsepower and 413 lb-ft of torque. This engine was mated to a seven-speed automatic transmission, with RWD as standard and 4WD as an option. The QX80's V8 provided ample power for highway overtaking, though the transmission shifts were not as smooth as expected. The SUV's body-on-frame construction contributed to a truck-like ride, but the independent suspension and Hydraulic Body Motion Control on Sensory models ensured a comfortable ride.

The QX80 excelled in towing and off-road capabilities, with a maximum towing capacity of 8,500 pounds. Its 4WD system included a low range and a forward skid plate, enhancing its off-road performance. However, its size and wheel-and-tire combinations limited its off-road prowess. On the road, the QX80's handling was less composed in corners, but its speed-sensitive power steering promoted a relaxed driving style.

The 2021 BMW X7 offered a luxurious interior with features like heated rear seats, ventilated and massaging front seats, and premium leather upholstery. Front-seat comfort was exceptional, with heated seats, armrests, and a steering wheel as standard. The second-row captain's chairs were also comfortable, though the long rear doors could make entry and exit challenging. The X7's third-row seating was surprisingly accommodating for adults, with a five-zone climate control system ensuring comfort for all passengers.

Cargo space in the X7 was limited, with 48.6 cubic feet available with the third row folded and 90.4 cubic feet with the second row down. While these figures were not class-leading, the X7's power clamshell tailgate and power-folding seats made cargo management easier.

The 2021 INFINITI QX80 came standard with a seven-seat configuration, with an optional eight-seat layout. The front seats offered power adjustments and heating and cooling on Sensory models, though the bottom cushions lacked thigh support. Passenger space was competitive, with ample room in all three rows. The second-row captain's chairs featured a large console with storage and climate controls, while the third row offered enough space for adults but lacked charging ports.

Cargo space in the QX80 was 16.6 cubic feet with all seats in place, 49.6 cubic feet with the third row folded, and 95.1 cubic feet with both the third and second rows down. While these figures were not segment-leading, the power liftgate and power-folding third row made cargo handling convenient. The center console offered limited storage, and the front-door cupholders were not well-designed for holding drinks securely.

The 2021 BMW X7 featured the Live Cockpit Professional digital instrumentation and iDrive 7.0 infotainment system, both with 12.3-inch displays. The iDrive system included Android Auto, Apple CarPlay, enhanced SiriusXM 360L, and Connected Package Pro with real-time traffic and parking information. Wireless smartphone charging, natural voice recognition, and gesture control were also available, though the latter was inconsistent. The head-up display was a useful feature, though it was difficult to see with polarized sunglasses.

The 2021 INFINITI QX80 was equipped with the InTouch dual-screen infotainment system, featuring 8.0-inch and 7.0-inch touchscreens. The system included Apple CarPlay, Android Auto, a WiFi hotspot, and navigation. A 13-speaker Bose audio system was standard, with an optional 17-speaker system and a Theater Package for rear-seat entertainment. The user interface was not intuitive, with small screens and complex controls. However, the Smart Rearview Mirror and Around View Monitor provided helpful driving aids.

The 2021 BMW X7 came standard with a comprehensive suite of safety technologies, with additional features available in the Driving Assistance Professional Package and Parking Assistance Package. The Driving Assistance Professional Package included features like evasive-steering assist, traffic-jam assist, and lane-control assist. The X7's advanced driving assistance systems were effective, though some specific situations revealed limitations in lane-maintenance technology. The Parking Assistance Package added semi-automated parking assist and a surround-view camera.

The 2021 INFINITI QX80 received a four-star overall safety rating from the NHTSA, with five stars for side crash tests and four stars for frontal crash tests. Standard safety features included adaptive cruise control, blind-spot monitoring, lane-departure warning, and automatic emergency braking. These features were common in mainstream SUVs, but Infiniti made them standard, unlike many luxury brands.
