More About This Class
BMW X7
The BMW X7 continues to stand tall as one of the largest and most refined luxury SUVs on the American market. It puts an emphasis on space, technology, and craftsmanship, making it a mainstay in the full-size premium SUV class. Buyers have a choice of two engine configurations, both of which come standard with xDrive all-wheel drive and an eight-speed automatic transmission.
The base model, known as the X7 xDrive40i, is powered by a 3.0-liter inline-six that incorporates a 48-volt mild-hybrid system. It produces 375 horsepower and 383 pound-feet of torque. BMW claims a 0 to 60 mph time of 5.6 seconds, which is more than adequate for a vehicle of this size.
For those who want more muscle, the X7 M60i xDrive features a 4.4-liter twin-turbocharged V8, also paired with a mild-hybrid setup. Output climbs to 523 horsepower and 553 pound-feet of torque. The M60i can hit 60 mph in just 4.5 seconds. The xDrive50i, previously part of the lineup, has been dropped for this generation.
Inside, the X7 offers seating for up to seven passengers, with the option to replace the second-row bench with two captain’s chairs for added comfort. Standard features include power-adjustable leather seats, a fully digital instrument cluster, and BMW’s curved display that integrates both infotainment and vehicle functions. The X7 runs on the latest iDrive 8 interface, which supports both touchscreen input and natural voice commands, along with over-the-air software updates.
Available equipment includes the Bowers & Wilkins Diamond Surround Sound System, a premium setup with 36 speakers and 1,500 watts of output that delivers exceptional audio clarity. This system is typically included in X7 models found in the Sixt rental fleet in the U.S. Also commonly equipped is the M Sport Package, which brings in sport-specific bumpers, unique wheels, an M leather steering wheel, and a firmer suspension tune that gives the X7 a more confident road presence.
The X7 doesn’t try to be flashy for its own sake. Instead, it delivers a well-rounded package with a clear focus on long-haul comfort, power when you need it, and an interior that’s both high-tech and well-executed.
Cadillac Escalade
The Cadillac Escalade remains one of the most recognizable names in the full-size luxury SUV segment in the United States. With its commanding presence, expansive interior, and extensive list of standard features, the Escalade continues to appeal to drivers who prioritize space, comfort, and confident performance in equal measure.
In its standard configuration, the Escalade is powered by a naturally aspirated 6.2-liter V8 engine that delivers 420 horsepower and 460 lb-ft of torque. Power is sent through a 10-speed automatic transmission, with rear-wheel drive as standard and four-wheel drive available as an option. For those seeking higher output, Cadillac offers the Escalade-V. This version uses the same engine block but adds a supercharger, raising output to 682 horsepower and 653 lb-ft of torque. It currently stands as the most powerful production vehicle Cadillac has ever built.
Inside, the Escalade is designed with long-distance comfort in mind. Depending on the seating configuration, it can accommodate up to eight passengers. Materials are upscale throughout, with extensive use of leather, open-pore wood trim, and metal accents. One of the focal points is the 38-inch curved OLED display, which spans the dashboard and integrates both the digital gauge cluster and infotainment system into a seamless unit. An optional 36-speaker AKG Studio Reference sound system offers a high-fidelity audio experience. Cadillac’s Super Cruise hands-free driving system is also available, enabling limited autonomous driving on compatible highways across the U.S.
Cargo space is generous, as expected for a vehicle in this class. Behind the third row, the Escalade provides approximately 25.5 cubic feet of storage. With the second and third rows folded, total cargo volume expands to just over 121 cubic feet.
In terms of driving dynamics, the Escalade places a clear emphasis on comfort and stability. Standard Magnetic Ride Control continuously adjusts the suspension to suit road conditions and driving inputs. Buyers can also opt for the Air Ride Adaptive Suspension, which automatically varies ride height and helps to minimize body roll during cornering. Despite its tall profile and curb weight exceeding 6,000 pounds, the Escalade remains composed and manageable behind the wheel. Steering is appropriately weighted and reasonably direct for a vehicle of this size, though the turning radius is wide due to the Escalade’s overall length, which measures just over 17.6 feet (roughly 211 inches) in its standard form.
On the highway, the ride is settled and quiet, with most surface imperfections effectively absorbed. At higher speeds, the Escalade feels stable and composed, though maneuvering in tighter urban settings or narrow lanes requires attention and familiarity with the vehicle’s dimensions.
Infinity QX80
The Infiniti QX80 enters its latest generation as a thoroughly redesigned full-size SUV, aimed squarely at buyers in the upper luxury segment. It prioritizes generous interior space, modern technology, and confident power delivery.
Under the hood, the QX80 features a 3.5-liter twin-turbo V6 that produces 450 horsepower and 516 pound-feet of torque. Power is channeled through a 9-speed automatic transmission. Rear-wheel drive is standard, with four-wheel drive offered as an option. According to EPA estimates, combined fuel economy is rated at approximately 17 mpg.
In terms of dimensions, the QX80 sits firmly in the upper tier of the luxury SUV category. It measures 211 inches in length, 83.5 inches in width, and up to 78 inches in height, depending on configuration. The wheelbase spans 121 inches. Cargo capacity is approximately 22 cubic feet behind the third row and expands to 101 cubic feet with the second and third rows folded flat.
The interior emphasizes comfort and digital integration. At its center is the new Monolith Display, which features two 14.3-inch touchscreens handling both infotainment and vehicle controls. The system supports Google Built-in, over-the-air updates, and onboard Wi-Fi connectivity. For audio, the available Klipsch Reference Premier system delivers up to 1,200 watts through as many as 24 speakers.
Comfort features include a tri-zone automatic climate control system with Biometric Cooling, which uses infrared sensors to monitor passenger body temperature and adjust airflow accordingly. Both the first and second rows offer ventilated seats, with optional massage functionality available.
Advanced driver assistance systems include adaptive cruise control, lane keeping assist, traffic sign recognition, and a surround-view camera with extended visibility. Infiniti’s ProPILOT Assist 2.1 is also available, offering hands-free driving under certain conditions on pre-mapped highways.
The QX80’s ride and handling are clearly tuned for long-distance comfort. An available adaptive air suspension automatically adjusts ride height and helps smooth out uneven pavement. Although the curb weight in well-equipped trims approaches 6,000 pounds, the vehicle remains stable and manageable. Steering is relatively direct for an SUV of this size, though the turning circle is predictably wide given its overall footprint.
