The AMG® GLE 63 S adds a 4.0-liter eight-cylinder hybrid engine in place of the GLE 53’s 3.0-liter six-cylinder, along with more power and a higher starting price. Mercedes-Benz of South Austin sells new AMG® and GLE models at 10900 S I-35 Frontage Rd, Austin, TX 78748.

The GLE 63 S makes 603 hp and 627 lb-ft, against 577 hp and 553 lb-ft for the GLE 53. For an Austin buyer choosing between these two AMG®s, the engine opens the question, and price, fuel economy, space and equipment settle it.

The AMG® GLE 63 S swaps the GLE 53’s six for a V8

The GLE 63 S runs a 4.0-liter eight-cylinder with a hybrid system, where the GLE 53 uses a 3.0-liter six. According to Mercedes-Benz’s published 2026 specifications, the GLE 63 S 4MATIC®+ SUV makes 603 hp and 627 lb-ft, and the GLE 53 HYBRID SUV makes 577 hp and 553 lb-ft.

Those are the figures that separate the two AMG® engines. Mercedes-Benz of South Austin sells new AMG® models, and it calls itself a Mercedes-Benz AMG® Performance Center.

How fast do the GLE 63 S and GLE 53 reach 60 mph?

Acceleration starts with power. According to Mercedes-Benz’s published 2026 figures, the GLE 63 S makes 603 hp and 627 lb-ft, and the GLE 53 makes 577 hp and 553 lb-ft. Both pair their engine with a 9-speed automatic and all-wheel drive.

How much more does the AMG® GLE 63 S cost than the GLE 53?

The GLE 53 is the starting point. According to Mercedes-Benz’s published 2026 pricing, the GLE 53 HYBRID SUV starts at $97,000 and the GLE 53 HYBRID Coupe at $98,000.

Texas adds sales tax to whatever you pay. Texas motor vehicle sales tax is 6.25% of the sales price, minus any trade-in allowance (Texas Comptroller of Public Accounts, 2026). Say, hypothetically, the GLE 53 HYBRID SUV sells at its $97,000 starting price. At 6.25%, the tax comes to $6,062.50 before any trade-in credit, and a higher sticker price means a larger tax bill.

Luxury models also lose value fastest. Luxury models make up 18 of the 25 fastest-depreciating vehicles in iSeeCars’ 2026 study (iSeeCars, 2026). Weigh the GLE 63 S against the GLE 53 on resale as well as the sticker.

What EPA mpg do the GLE 63 S and GLE 53 get?

The GLE 63 S gets 17 mpg combined in both body styles, and the GLE 53 gets 20 mpg combined in both. These are EPA-certified figures for the 2026 model year.

EPA certification for the 2026 model year sets these ratings.

EPA’s combined figure weights city driving at 55% and highway driving at 45%. The Texas A&M Transportation Institute ranks I-35 from US 290 North to Ben White Boulevard as the ninth most congested road segment in Texas for 2025 (Texas A&M Transportation Institute, 2025). For an Austin commute, the 15 mpg city rating on the GLE 63 S is the number to weigh most.

How do seating, cargo and towing compare on the GLE 63 S and GLE 53?

The GLE 63 S and GLE 53 SUVs share the same space. Both carry 74.9 cubic feet of maximum cargo, 40.3 inches of first-row legroom and 40.9 inches of second-row legroom, according to Mercedes-Benz’s published specifications. Both tow up to 7,700 lbs in SUV and Coupe form.

The GLE 350 and GLE 450 are also rated at 7,700 lbs, so towing does not set the AMG® pair apart. For a family hauling gear, the GLE 63 S adds no cargo room over the GLE 53 SUV.

What standard features set the GLE 63 S apart from the GLE 53?

Both AMG® trims carry the GLE-Class basic warranty of 4 years or 50,000 miles, so coverage does not separate them. What sets the GLE 63 S apart is its engine, the 4.0-liter eight-cylinder with 603 hp and 627 lb-ft.

In a September 2026 Google review, Maribeth C. wrote: “Unexpected tire issues before flying out of Austin. Car was towed to MBSA & they took care of issue while I was away keeping me informed daily & had car ready upon my return. Their service/communication made my trip easier w/o worrying about car upon my return. Slader did an outstanding job. Would definitely recommend MBSA for good customer service & quality work.” That review describes one customer’s service visit, and it is the kind of ownership support the warranty sits beside. Ask for the equipment list on the exact trim you are considering when you visit.

Who should choose the GLE 63 S and who the GLE 53?

Choose the GLE 63 S if 603 hp and 627 lb-ft matter more to you than the price and the fuel rating. Choose the GLE 53 if 577 hp and 553 lb-ft cover your driving at a lower starting price, which is $97,000 for the SUV.

Both AMG® engines come in SUV and Coupe body styles, so body style is a separate choice from the engine. Buyers who want less than either AMG® can look at the GLE 450 4MATIC® SUV, which starts at $74,800 and makes 375 hp and 413 lb-ft.

In a May 2025 Google review, Xinyi M. wrote: “I did a test drive at this place. It has been a great experience. Ken did great work helping me find the right car. Ken is definitely professional and truly helps me find a car that is right for me instead of trying to persuade me to buy a car that might have any minor mismatch with my actual needs. Ken truly cares about the customers and uses his expertise to help me figure out what a right car, a best car is for my condition. Even the original car I went to take the test drive seems not perfect for me, Ken keeps me updated on the potential vehicles that could be worth a try. Car searching can be overwhelming. However, Ken makes things so much easier and more reassuring.” A buyer who wants help narrowing the trim can ask for the same kind of walk-through.
