GLS vs. GLE size comparison at a glance

The comparison below uses current U.S.-market specifications for the 2026 GLS 450 4MATIC and 2026 GLE 350 4MATIC SUV. Comparing the same model year and the standard SUV body is important because AMG, Maybach, plug-in hybrid, and GLE Coupe versions can have different measurements.

Measurement	2026 GLS 450 4MATIC	2026 GLE 350 4MATIC	GLS difference
Overall length	205.0 in	194.3 in	10.7 in longer
Wheelbase	123.4 in	117.9 in	5.5 in longer
Width without mirrors	79.9 in	76.7 in	3.2 in wider
Width with mirrors	84.9 in	84.9 in	No listed difference
Overall height	71.8 in	70.7 in	1.1 in taller
Maximum cargo capacity	84.7 cu. ft.	74.9 cu. ft.	9.8 cu. ft. more
Standard passenger capacity	7; 6 optional	5; 7 optional	GLS prioritizes three rows

Bottom line: The most noticeable exterior difference is length, not mirror-to-mirror width. The GLS needs roughly 11 inches more garage length and has a substantially longer wheelbase, while both listed models are 84.9 inches wide with mirrors.

How much longer is the GLS than the GLE?

Using the current base SUV specifications, the GLS is 205.0 inches long and the GLE is 194.3 inches long. That makes the GLS 10.7 inches longer. The difference can matter in a short garage, in parallel-parking spaces, and when maneuvering around a tight driveway.

The GLS wheelbase is 123.4 inches, compared with 117.9 inches for the GLE. That additional 5.5 inches helps explain why the GLS is designed around a more usable three-row cabin. A longer wheelbase does not automatically tell you every interior measurement, but it is an important part of the GLS’s larger packaging.

Is the GLS much wider than the GLE?

Without mirrors, the GLS is 79.9 inches wide and the GLE is 76.7 inches wide, a difference of 3.2 inches. Mercedes-Benz lists both vehicles at 84.9 inches wide with mirrors for these configurations.

For a garage check, use the width-with-mirrors figure and allow additional clearance to open the doors. For comparing body size or cabin packaging, the width-without-mirrors figure is more informative. Older articles often mix these two measurements, which can create the false impression that one model is dramatically wider.

Which has more cargo space?

Mercedes-Benz lists a cargo-capacity range of 17.4 to 84.7 cubic feet for the GLS 450 and 33.3 to 74.9 cubic feet for the GLE 350 4MATIC. The GLS therefore provides 9.8 cubic feet more maximum cargo volume with the relevant seating folded.

The smaller minimum number for the GLS does not mean it has less useful cargo room overall. It reflects the space measured behind its occupied third row. The GLE’s standard layout has two rows, so its cargo floor begins farther forward unless it is equipped with the optional third row. For real luggage planning, compare the exact seating configuration you will use instead of relying only on the maximum number.

Does the GLE have a third row?

The 2026 GLE SUV is listed for five passengers with seating for seven available as an option. The GLS is listed for seven passengers as standard, with a six-seat configuration available. The GLS is therefore the more natural choice when the third row will be used frequently.

A GLE with the optional third row may work for occasional extra passengers, but buyers should inspect access, legroom, and remaining luggage space in person. If two-row use, easier parking, and a shorter body are higher priorities, the GLE is usually the more practical package.

Why older GLS and GLE measurements conflict

Measurements vary by generation, model year, body style, and trim. The GLE Coupe is not dimensionally identical to the GLE SUV, and AMG or Maybach GLS versions can differ from the GLS 450 used here. Some legacy comparisons also combine specifications from different generations or confuse width with mirrors and width without mirrors.

When checking a used vehicle, match the year, trim, and body style shown on the VIN record or window sticker to the corresponding Mercedes-Benz specification sheet. Do not apply the 2026 differences above to every GLS and GLE ever produced.

Which one should you choose?

• Choose the GLS if you regularly need three rows, greater maximum cargo capacity, or more second- and third-row flexibility.
• Choose the GLE if five-seat use is typical and easier parking or garage fit matters more than maximum space.
• Measure before buying if your garage is tight. Check usable door opening, mirror clearance, charging or storage equipment, and the space needed behind the vehicle.
• Test the exact configuration if you need seven seats. Optional equipment and seat layout can change passenger and cargo usability.
