Top 3 GLS questions from Gilbert shoppers
GLS or GLE: do I need the bigger SUV?
Get the GLS if adults or teenagers ride in the third row: it is 10.9 inches longer than the GLE 450 (205.4 vs. 194.5 in), gives third-row passengers 34.6 inches of legroom, and still holds 17.4 cubic feet of cargo behind the third row. Get the GLE if the third row is only for occasional use: the GLE 450 offers an optional third row from $74,800 MSRP, $19,150 less than the GLS 450 at $93,950, with the same 375-hp inline-six and the same 7,700-lb tow rating. Our GLE vs. GLS guide for East Valley families goes further, and the Mercedes-Benz GLE guide has its trims and specs.
GLS 450 or GLS 580: is the V8 worth $27,000?
For most families the GLS 450 is enough: it starts at $93,950 MSRP, $27,000 less than the GLS 580 at $120,950, and both have the same seats, the same 17.4 to 84.9 cubic feet of cargo room and the same 7,700-lb tow rating. The GLS 580 is worth it if you want the 530-hp V8, which runs 0–60 mph in 4.6 seconds against 5.4 for the 375-hp GLS 450, or if you regularly climb the grade to Payson with a full load or a trailer. Drive both back to back on the Loop 202 and the Beeline to feel the difference.
Will a Mercedes-Benz GLS fit in my garage?
The 2027 GLS 450 is 205.4 inches long (about 17 feet 1 inch), 79.0 inches wide without the mirrors (85.2 inches with them) and 71.8 inches tall, according to Mercedes-Benz USA. That fits most standard two-car garages in Gilbert, Chandler and Queen Creek with room to walk around the front, but measure the depth of an older or shallow garage and the width of a single-car door before you buy. Bring your measurements to Mercedes-Benz of Gilbert and we can check fit, or bring the GLS home on a test drive.
GLS vs. BMW X7
The BMW X7 is the GLS’s closest rival. The X7 xDrive40i starts $6,450 lower and offers seven seats as standard, against six (seven optional) in the GLS 450, and it has more maximum cargo room (90.4 vs. 84.9 cu ft). The GLS 450 matches its 375 hp, is a little quicker (0–60 mph in 5.4 seconds against 5.6), tows 200 pounds more (7,700 vs. 7,500 lb), is 1.8 inches longer and has a bigger fuel tank for long desert drives (23.8 vs. 21.9 gallons). Mercedes-Benz also offers a Mercedes-Maybach version, which BMW doesn’t. The best way to choose is to drive them back to back; the GLS is waiting at Mercedes-Benz of Gilbert.

GLS, Mercedes-AMG® GLS 63 or Mercedes-Maybach GLS 680?
Choose the GLS 450 or GLS 580 for a family SUV: three full rows, up to 84.9 cubic feet of cargo room and a 7,700-lb tow rating, from $93,950 MSRP. Choose the Mercedes-AMG® GLS 63 for performance with all three rows: its handcrafted 603-hp V8 runs 0–60 mph in 4.0 seconds, the quickest of any three-row Mercedes-Benz. Choose the Mercedes-Maybach GLS 680, from $185,000, if the back seat matters most: it drops the third row for four or five seats, 43.4 inches of rear legroom (52.8 inches in the chauffeur position) and the same 603-hp V8, rated 14 city / 20 highway mpg. Ask our sales team about Mercedes-Maybach GLS availability and ordering, or shop AMG® inventory. For the Mercedes-Maybach sedan, see the Mercedes-Benz S-Class guide.
