2025 Mercedes-Benz AMG GT Review

The big news for 2025 is the release of three new models: the 603-horsepower AMG GT63 Pro, a top-of-the-line 805-horsepower plug-in hybrid called the GT63 S E Performance, and the base-level GT43 with a turbocharged four-cylinder engine and rear-wheel drive.

Pros

• There are supercharged V-8 and inline-4 engines.
• Those are very good reactions.
• It’s a very quiet cottage.

Cons

• Louder and more noticeable exhaust design.
• Instead of paddle shifters, there are now buttons.
• Unresponsive steering feel.

In the new GT43 for 2025, the four-cylinder engine has an electric exhaust-gas turbine and a 48-volt hybrid starter/generator. It has 416 horsepower. By keeping the turbo on spool, the 48-volt electricity system cuts down on the time between stepping on the gas and exhaust gases taking over to give the most boost. Neither the GT55 nor the GT63 have a twin-turbo 4.0-liter V-8 engine. The GT55 has 469 horsepower, while the GT63 has 577 horsepower. The GT63 Pro improves on the GT63’s good points by adding a better cooling system and increasing power to 603 horsepower. This will help keep temperatures stable on the track. The GT63 S E Performance has an electric motor that adds 805 horsepower to the total. Instead of a torque converter, all models have a nine-speed automatic gearbox with a clutch. This is meant to cut down on weight and improve acceleration response. All three cars have a limited-slip rear differential that is controlled electrically. The all-wheel drive GT55 and GT63 can send all of their engine power to the back wheels. The GT is more quick because it has rear-wheel steering, but we didn’t find the GT63 as exciting to drive as the GT. The GT63 S E Performance hybrid was much more powerful during our test drive. The electric motors’ lightning-fast acceleration more than made up for the extra weight compared to the non-hybrid type. The optional nose-lift system for the AMG GT lifts the front end by 1.2 inches. This makes it easier to drive on rough driveways and speed bumps.

There will be many driver assistance systems to choose from, but it needs to be clarified which ones will come standard and which ones will be extra. Visit the Insurance Institute for Highway Safety (IIHS) and National Highway Traffic Safety Administration (NHTSA) webpages to learn more about the GT Coupe’s crash test scores. Some important safety features could be:

• Most self-driving emergency brakes can tell who is on the road.
• An warning that helps you stay in your lane when you need to leave it.
• You can get variable speed control that will keep your car in its lane.

Mercedes-AMG says the new GT43 will take 4.5 seconds to go from 0 to 60 mph, while the GT63 went from 0 to 60 mph in 2.7 seconds in our tests. Mercedes-AMG also says that the more powerful GT63 S E Performance model will be offered at the same time, which is interesting. Based on what we know about the SL43 and SL63 convertibles, we can probably subtract one or two-tenths from each of those predicted numbers during C/D testing.

The new GT is more appealing because its interior is a little bigger, and the view from the outside is better. Regular sports seats are a good mix of comfort and support, while AMG sports seats offer more lateral support. Three massage routines can also help you on long trips. Nappa leather upholstery comes in a number of different styles, such as a leather-microfiber blend and a diamond quilted design. The new GT indeed has a back seat, but it’s very small—just like in a Porsche 911—and should only be used for very large items or situations. They say that the back seats “are suitable for occupants less than five feet tall,” which is a huge exaggeration. The motorized back hatch opens without using your hands and can hold two golf bags or 23.8 cubic feet of stuff.

The EPA says that the GT55 and GT63 will get 13 mpg in the city and 20 mpg on the highway. The GT43’s EPA number is unknown, but it will be about the same as the Mercedes-AMG SL43, which gets 20 mpg in the city and 27 mpg on the highway thanks to a slightly tweaked engine. We’ll put the GT Coupe through our real-world highway fuel-economy test at 75 mph as soon as we can and add the results to this story. 

All AMG GT Coupes have an 11.9-inch touchscreen for entertainment, but some people may find it hard to use the menus. All models have a Burmester music system, Apple CarPlay and Android Auto built-in, and a wireless charging pad for your phone. As an extra, you can get a high-tech Burmester 3D Surround Sound System with 15 speakers and 1,170 watts.

Mercedes-AMG says the new GT43 will take 4.5 seconds to go from 0 to 60 mph, while the GT63 went from 0 to 60 mph in 2.7 seconds in our tests. Mercedes-AMG also says that the more powerful GT63 S E Performance model will be offered at the same time, which is interesting. Based on what we know about the SL43 and SL63 convertibles, we can probably subtract one or two-tenths from each of those predicted numbers during C/D testing.

The price of the 2025 model hasn’t been set yet, but the GT55 and GT63 won’t be much more expensive than they were in 2024. The Mercedes-AMG GT43 car and SL43 are our top picks for 2025 models. However, the GT43 will likely cost more than $115,000 because it doesn’t have all-wheel drive. There is no question that the new GT63 S E Performance plug-in hybrid will cost the most. All four of the GT cars aren’t cheap, but their prices are about the same as those of their main rival, the Porsche 911. You can customize your car in a number of ways. The AMG Night Package adds a gloss black front splitter, side sill trims, and mirror caps. The AMG Chrome Package adds chrome to the front bumper, front mudguards, and side sill trims. The Aero kit comes with a fixed AMG rear wing, a bigger rear diffuser, and new air vents that are all gloss black. Overall, we like this kind of fast car best when it has enough power, which is why we like the GT63.
