Mercedes-Benz GLE SUV Size & Dimensions vs. the Competition

When shopping for a midsize luxury SUV, dimensions matter a lot. The right balance of exterior size, interior space, and cargo flexibility can make the difference between a vehicle that fits your life and one that falls short. 

The Mercedes-Benz GLE has long set the benchmark in this segment, and when you compare it side-by-side against rivals from Cadillac, BMW, Acura, Volvo, and Buick, it’s easy to see why.

Mercedes-Benz GLE: The Benchmark

The 2026 GLE strikes the ideal balance between commanding exterior presence and genuinely usable interior space. At nearly 195 inches long and riding on a class-competitive 117.9-inch wheelbase, it delivers exceptional rear legroom of 40.9 inches,  among the best in segment, without feeling oversized in everyday driving situations.​

• Length: 194.3 inches
• Width: 76.7 inches
• Height: 70.7 inches
• Maximum Cargo Space: 74.9 cu ft (seats folded) / 33.3 cu ft (seats up)
• Passengers: 5 standard; 7 with optional third row​

Mercedes-Benz GLE vs. BMW X5

The BMW X5 is the GLE’s most storied and competitive rival, and the size comparison is remarkably close. Both vehicles share an identical length of 194.3 inches, making them essentially the same footprint on the road. Where they diverge is in height, the GLE stands 1.6 inches taller than the X5, giving it a slightly more upright and commanding profile. The GLE also edges out the X5 on maximum cargo by 2.6 cu ft, and its optional third-row configuration gives family buyers more flexibility than the X5’s standard 5-seat setup.

• Length: 194.3 inches (identical to GLE)
• Width: 78.9 inches (+2.2 in wider than GLE)
• Height: 69.1 inches (1.6 in lower than GLE)
• Maximum Cargo Space: 72.3 cu ft (2.6 cu ft less than GLE)
• Passengers: 5​

Mercedes-Benz GLE vs. Cadillac XT5

The Cadillac XT5 is the smallest vehicle in this comparison and the one that falls furthest short of the GLE’s dimensions across the board. At just 189.6 inches long, 4.7 inches shorter than the GLE, the XT5 offers a noticeably more compact footprint that translates directly into less usable space inside. 

Its maximum cargo capacity of just 63.0 cu ft falls nearly 12 cu ft short of the GLE’s 74.9 cu ft, and without an available third-row configuration, it’s limited to five passengers regardless of trim. For buyers who need the space, comfort, and flexibility of a true midsize luxury SUV, the XT5 simply doesn’t measure up.

• Length: 189.6 inches (4.7 in shorter than GLE)
• Width: 74.9 inches (1.8 in narrower than GLE)
• Height: 66.1 inches (4.6 in lower than GLE)
• Maximum Cargo Space: 63.0 cu ft (11.9 cu ft less than GLE)
• Passengers: 5 only and no third row available​

Mercedes-Benz GLE vs. Acura MDX

The Acura MDX is one of the more spacious rivals on this list, stretching 4.1 inches longer than the GLE at 198.4 inches. Its standard three-row, seven-seat configuration is a genuine highlight for larger families. However, that extra length doesn’t translate into more cargo space, the MDX’s 71.4 cu ft maximum falls 3.5 cu ft short of the GLE, and at 67.9 inches tall, it’s noticeably lower than the GLE’s 70.7 inches, giving the GLE a more commanding presence on the road. The MDX’s additional length also makes it less maneuverable in tight urban environments despite offering a similar overall interior experience.

• Length: 198.4 inches (4.1 in longer than GLE)
• Width: 78.7 inches (+2.0 in wider than GLE)
• Height: 67.9 inches (2.8 in lower than GLE)
• Maximum Cargo Space: 71.4 cu ft (3.5 cu ft less than GLE)
• Passengers: 7 standard​

Mercedes-Benz GLE vs. Volvo XC60

While the XC60 competes one segment below the GLE in Volvo’s lineup, it’s frequently cross-shopped by buyers comparing compact and midsize luxury SUVs. At 185.4 inches long, the XC60 is a notably more compact vehicle (8.9 inches shorter than the GLE) which shows clearly in its interior and cargo figures. 

Its maximum cargo capacity of 63.3 cu ft falls 11.6 cu ft short of the GLE, and it seats just five passengers with no third-row option available. The GLE’s taller stance, longer wheelbase, and significantly more spacious cabin make it the clear choice for buyers who need a genuinely full-size luxury SUV experience.

• Length: 185.4 inches (8.9 in shorter than GLE)
• Width: 73.9 inches (2.8 in narrower than GLE)
• Height: 65.2 inches (5.5 in lower than GLE)
• Maximum Cargo Space: 63.3 cu ft (11.6 cu ft less than GLE)
• Passengers: 5​

Mercedes-Benz GLE vs. Buick Envision

The Buick Envision sits firmly in the compact luxury SUV segment, making it a smaller and less capable rival to the GLE in terms of sheer size and space. At 182.7 inches long,  a full 11.6 inches shorter than the GLE, the Envision delivers a noticeably more compact experience that limits both passenger comfort and cargo flexibility. 

With just 52.7 cu ft of maximum cargo capacity, it falls 22.2 cu ft short of the GLE, and like the XT5, it offers no third-row seating option. For buyers considering the Envision alongside the GLE, the difference in overall size and interior space becomes immediately apparent at the test drive.​

• Length: 182.7 inches (11.6 in shorter than GLE)
• Width: 74.1 inches (2.6 in narrower than GLE)
• Height: 64.6 inches (6.1 in lower than GLE)
• Maximum Cargo Space: 52.7 cu ft (22.2 cu ft less than GLE)
• Passengers: 5 only and no third row available​
