2025 Mercedes-AMG GT43 Brings In New 416 Horsepower Four-Cylinder Entry Model

The downsizing continues with the 2025 Mercedes-AMG GT43 coupe.

On Tuesday, Mercedes-AMG debuted the latest entry-level model of its top-rung GT coupe, packing a 2.0-liter four-pot engine. It doesn’t sound too impressive when you put it that way, but it still makes a hearty amount of grunt thanks to an electric turbocharger. In fact, the 2025 Mercedes-AMG GT43 packs AMG’s M139 engine, putting out 416 horsepower and 369 lb-ft of torque. As a nod to “purists” to whom the automaker expressly says this car is for, the ’43’ model also loses 4Matic all-wheel drive in favor of a rear-wheel drive setup.

“The rear-wheel drive concept makes the GT43 a very agile vehicle that will put a smile on your face on winding roads,” says Mercedes-AMG CEO Michael Schiebe. That is, despite lacking a V8 or even a six-pot under the hood, the company says this is still every bit an AMG GT. The electric exhaust gas turbocharger is technology used by the Petronas F1 team, while this entry-level version still gets a 9-speed multi-clutch transmission that uses a wet start-off clutch in place of a conventional torque converter. That means lower weight and less inertia off the line, so the 43 should be able to make better use of that 416 horsepower on launch. At least, that’s what Mercedes-AMG claims.

Like other cars in Mercedes’ latest portfolio, the 2.0-liter engine also brings in a 48-volt mild-hybrid system. An electric motor adds up to 13 horsepower of extra boost off the line. For reference, the new GT43 manages 54 more horsepower than the old one with the 3.0-liter turbocharged inline-six, making for a lower 4.5-second 0-60 time (versus 4.8 for the last GT43). However, that is still half a second slower than the all-wheel drive CLA45 with the exact same engine, not to mention it’s still down on the 429-horsepower GT53 and leagues behind the 577-horsepower GT63. (This model will be significantly less expensive, though.)

Compared to the higher-performance models, the GT43 sports standard steel coil-sprung suspension with composite brakes and a narrower track. You can get rear-wheel steering and AMG’s Ride Control Chassis as options, as well as the AMG Dynamic Plus package that adds in active engine mounts, an electronic limited-slip rear differential, active underbody aerodynamics and a “Race” mode fro the Dynamic Select drive programs. By default, you get Slippery, Comfort, Sport, Sport+ and Individual.

To differentiate the GT43 from its siblings a bit, this new model gets a redesigned front bumper with a completely different lower fascia to the V8-powered GT63. Around back, the lower bumper is also different, while you get circular quad exhaust pipes, rather than trapezoidal ones. The entry level version also loses the rear wing on the decklid that you get with the hotter model, though you can get it back as an option.

If you want to change things up even further, Mercedes does offer the option of 21-inch wheels as well as gloss black accents, which do offer some nice contrast against the Solarbeam Yellow paint.

Looking inside the 2025 Mercedes-AMG GT43

As much as I probably sound like a broken record saying it, the updated GT43 brings “your typical Mercedes fare” to the party. You get a 12.3-inch digital gauge cluster as well as an 11.9-inch center infotainment screen, as well as a three-spoke flat-bottom AMG steering wheel with split side spokes for all the capacitive buttons. Sitting just below those side spokes, you get two rotary dials to control the drive modes as well as the exhaust and suspension settings, among other driving-related options.

2025 Mercedes-AMG GT43 buyers will get Nappa leather sports seats as standard equipment, though you can upgrade to the more hardcore AMG Performance seats. Interior trim elements come in either piano black, aluminum, carbon fiber and aluminum, though you can get grey open-pore birch wood or brown open-pore ash ship deck wood with aluminum lines, if you want.

Pricing information for the new GT43 is not available just yet. It should start off somewhere around the $100,000 mark based on the past model’s MSRP. We should know more as the company builds out its updated build pages, while the new Mercedes-AMG GT43 coupe will actually launch later this year, as it will land for the 2025 model year (so think second-half of 2024). This isn’t the only new AMG GT coming down the pike, either: Mercedes is also bringing in an 800-horsepower GT73 plug-in hybrid V8 as the new top-dog.
