If you've been lusting after the Mercedes-AMG GT 4-Door, the least expensive way to get one has been the GT53 model for $99,950. Powered by a 3.0-liter mild-hybrid inline-six producing 429 horsepower, the GT53 has been an admirable entry-level model for the GT 4-Door lineup. But that is about to change. The 2021 Mercedes-AMG GT will now include a new entry-level GT43 model. Previously only available in Europe, the GT43 is powered by the same inline-six used in the GT53 but with less power.

This new entry-level AMG actually produces the same amount of power found in a variety of non-AMG models powered by the 3.0-liter turbocharged inline-six with the mild-hybrid assist. The output is rated at 362 hp and 369 lb-ft of torque with an additional 21 hp and 184 lb-ft of torque coming from the EQ Boost mild-hybrid system.

As with other GT 4-Door models, the GT43 sends its grunt to a 4MATIC+ all-wheel-drive system through a nine-speed automatic transmission. The 2021 GT 4-Door lineup will still include the mid-level GT53 model and the flagship GT63 S with a 4.0-liter twin-turbocharged V8 producing 630 hp. Mercedes estimates a 4.8-second 0-60 mph time for the GT43, which is only 0.4 of a second behind the more powerful GT53 but well behind the blistering 3.1-second time of the top trim GT63 S. No output changes have been announced for either the GT53 or GT63 S, so they should remain the same for 2021.

The most significant upgrade in the cabin is the replacement of the COMAND infotainment system with the Mercedes-Benz User Interface (MBUX). This will be a welcomed change for a model that sits as the flagship in the AMG lineup. Mercedes hasn't mentioned specific pricing for the 2021 GT53 or GT63 S, so we expect them to remain around $99,950 and $140,250 respectively.

The 2021 Mercedes-AMG GT43 will be the least expensive of the three with a more affordable starting price of $89,900. US deliveries will begin in late 2020.
