Mercedes-Benz AMG® GT 43 or AMG® GT 63: which AMG® GT fits Austin drivers?
Pick the AMG® GT 43 if the car is your daily driver and a lower starting price matters most. Pick the AMG® GT 63 if power and acceleration come first. If you live south of I-35 in Austin, Buda, Kyle or Dripping Springs, both trims are sold at Mercedes-Benz of South Austin, 10900 S I-35 Frontage Rd, Austin, TX 78748. Price, Texas charges and fuel economy shape the rest of the decision for a buyer in this part of Austin.

How much more does the AMG® GT 63 cost than the AMG® GT 43?
The AMG® GT 43 Coupe starts at $106,500 and the AMG® GT 63 Coupe at $184,000, a $77,500 gap, before options, tax and fees. Texas then taxes either trim the same way: 6.25% of the sales price, minus any trade-in allowance (Texas Comptroller of Public Accounts, 2026).
Say, hypothetically, a $100,000 sticker price with no trade-in. The tax on that price is $6,250. A $20,000 trade-in lowers the taxable price to $80,000, and the tax falls to $5,000.
Title and registration costs are the same for either trim. The base registration fee for a car is $50.75, and the renewal line shows $51.75 once the $1 TexasSure fee is added (Texas Department of Motor Vehicles, 2026). Local county fees are added on top of that.
What are the EPA fuel economy ratings for the AMG® GT 43 and GT 63?
The two trims use different engines, so their EPA ratings differ. The AMG® GT 43 is a hybrid, and the AMG® GT 63 runs an eight-cylinder gasoline engine. The EPA’s combined figure weights city driving at 55% and highway driving at 45% (EPA, 2026).
Because city driving carries the bigger weight, a buyer who drives mostly in town should read the city number first. The EPA rates the AMG® GT 43 Coupe at 19 city, 27 highway and 22 combined mpg, and the AMG® GT 63 4MATIC®+ Coupe at 14 city, 20 highway and 16 combined.
