We’ll also explore their cargo versatility, ownership costs, and overall value propositions, helping you determine which luxury SUV best aligns with your needs and desires.
Exterior Design and Styling
When it comes to making a bold statement on the road, both the BMW X7 and the Mercedes-Benz GLS excel in their own unique ways. The X7 embodies BMW’s latest design language, with its imposing kidney grille and muscular body lines that exude a sporty and athletic stance. Meanwhile, the GLS takes a more stately approach, with its upright and commanding presence complemented by Mercedes’ signature styling cues, such as the striking LED headlights and the brand’s iconic three-pointed star emblem.
Both SUVs offer a wide range of exterior color options, from sophisticated hues like Mineral White and Obsidian Black to more daring shades like the BMW’s Brooklyn Grey and the Mercedes’ Hyacinth Red Metallic. Wheel sizes can vary from 20 to 23 inches, allowing owners to further personalize the look and stance of their luxurious rides.
Luxurious Interiors: A Sumptuous Cabin Experience
Step inside either the BMW X7 or the Mercedes-Benz GLS, and you’ll be greeted by a world of opulence and refinement. These flagship SUVs spare no expense when it comes to interior craftsmanship, with exquisite materials like premium leathers, real wood trims, and brushed aluminum accents adorning their cabins.
The X7 and GLS both offer seating configurations for up to seven passengers, with the option of second-row captain’s chairs for added comfort and convenience. However, the GLS takes the lead when it comes to overall interior space, offering more legroom and headroom in the second and third rows, making it a better choice for families or those who frequently transport passengers.
Both SUVs are equipped with cutting-edge infotainment systems, featuring large touchscreens, intuitive controls, and seamless integration with popular smartphone platforms like Apple CarPlay and Android Auto. The X7 and GLS also boast an array of comfort and convenience amenities, such as multi-zone climate control, ambient lighting, and premium audio systems from brands like Bowers & Wilkins and Burmester.
Power and Performance
Under the hood, the BMW X7 and the Mercedes-Benz GLS offer a range of potent powertrains to satisfy even the most demanding drivers. The X7’s base engine is a turbocharged 3.0-liter inline-six that produces 335 horsepower and 330 lb-ft of torque, while the GLS’s standard powertrain is a turbocharged 3.0-liter inline-six with a mild-hybrid assist, generating 362 horsepower and 369 lb-ft of torque.
For those seeking even more exhilarating performance, both SUVs offer powerful V8 engine options. The X7 M50i variant packs a 4.4-liter twin-turbo V8 that churns out an impressive 523 horsepower and 553 lb-ft of torque, while the Mercedes-AMG GLS 63 boasts a handcrafted 4.0-liter twin-turbo V8 that delivers a staggering 603 horsepower and 627 lb-ft of torque.
Regardless of the engine choice, both the X7 and the GLS offer confident handling and a composed ride, thanks to their advanced suspension systems and innovative chassis technologies. The X7 features an adaptive air suspension and an optional rear-wheel steering system for improved maneuverability, while the GLS employs Mercedes’ E-Active Body Control system, which can lean into corners and even “bounce” the vehicle for improved traction on loose surfaces.
Efficiency and Fuel Economy
While both the BMW X7 and the Mercedes-Benz GLS prioritize performance, they also strive to deliver respectable fuel efficiency for their size and capabilities. The X7’s base 3.0-liter engine is rated at 21 mpg in the city and 25 mpg on the highway, while the GLS’s mild-hybrid inline-six achieves an EPA-estimated 19 mpg city and 24 mpg highway.
It’s worth noting that opting for the more powerful V8 engines in either SUV will inevitably result in lower fuel economy figures. However, both BMW and Mercedes have implemented advanced technologies, such as start-stop systems and intelligent transmission programming, to help mitigate the impact on fuel consumption.
For those seeking even greater efficiency, the Mercedes-Benz GLS also offers a plug-in hybrid variant, the GLS 580e, which pairs a turbocharged 3.0-liter inline-six with an electric motor and a battery pack, allowing for short-distance electric-only driving and improved overall fuel economy.
Cargo Versatility and Practicality
As full-size luxury SUVs, both the BMW X7 and the Mercedes-Benz GLS excel in cargo versatility and practicality. The X7 offers up to 90.4 cubic feet of cargo space with the second and third rows folded, while the GLS boasts a slightly larger maximum cargo capacity of 94.7 cubic feet.
However, when it comes to cargo space behind the third row, the GLS takes the lead, offering 17.4 cubic feet compared to the X7’s 12.8 cubic feet. This advantage could be crucial for families or those who frequently need to transport larger items while carrying passengers in all three rows.
Both SUVs feature power-folding third-row seats and split-folding second-row seats, allowing for various cargo and passenger configurations. Additionally, they offer hands-free power liftgates, making it easier to load and unload cargo with your hands full.
When it comes to towing capabilities, the X7 and GLS are evenly matched, with maximum towing capacities of 7,500 pounds and 7,700 pounds, respectively. This impressive towing prowess allows owners to bring along boats, trailers, or other recreational equipment on their adventures.
Advanced Safety and Driver Assistance Systems
Safety is a top priority for both BMW and Mercedes-Benz, and their flagship SUVs are equipped with a comprehensive suite of advanced driver assistance systems and safety features. Both the X7 and the GLS come standard with automatic emergency braking, lane-keeping assist, and blind-spot monitoring, among other active safety technologies.
Additionally, both SUVs offer advanced parking aids, including surround-view camera systems and semi-autonomous parking assist functions, making it easier to maneuver these large vehicles in tight spaces.
For those seeking even more cutting-edge safety features, the BMW X7 offers options like Night Vision with Pedestrian Detection and BMW’s Extended Traffic Jam Assistant, which can take over steering, braking, and acceleration in stop-and-go traffic situations.
The Mercedes-Benz GLS, on the other hand, offers exclusive features like the brand’s Attention Assist system, which can detect and alert drowsy drivers, and the innovative Pre-Safe impulse side system, which can prepare the vehicle for an imminent side impact by inflating air chambers in the seats to better protect occupants.
As you move up the trim levels and add optional packages, the prices can quickly escalate well into the six-figure range for both SUVs. However, it’s important to consider the overall value proposition offered by each model.
The BMW X7 tends to be the more affordable option when comparing similarly equipped variants. It also comes with a more generous warranty coverage, including a 4-year/50,000-mile basic warranty and a 3-year/36,000-mile complimentary maintenance program.
On the other hand, the Mercedes-Benz GLS often commands a higher price tag but offers a more spacious and versatile interior, as well as the potential for better resale value down the line, thanks to the brand’s strong reputation in the luxury segment.
When it comes to long-term ownership costs, both the X7 and the GLS are expected to incur higher maintenance and repair expenses compared to more mainstream SUVs. However, these costs are typically offset by the superior build quality, premium materials, and advanced engineering found in these flagship models.
Ultimately, the decision between the BMW X7 and the Mercedes-Benz GLS may come down to personal preferences and priorities. Those who value performance, driving dynamics, and a more engaging driving experience may gravitate towards the X7, while those seeking the utmost in interior space, comfort, and brand cachet may find the GLS to be the more appealing choice.
