Mercedes-Benz introduced the fourth generation of the A-Class in 2018, and AMG introduced a more powerful version for it in 2019.

Mercedes-Benz was successful with the first generation of the A-Class 45 AMG, and when it switched to the second iteration of this hatchback, it also changed the name to Mercedes-AMG A45 4MATIC+.

The 2018 AMG A35 was a true hot-hatch. Even if it wasn't the top-spec AMG from the A-class, it was considered to give a better balance and enough everyday performance.

Mercedes-AMG entered into the hot-hatch segment where it didn't belong, but it wanted to dominate with the presence of the A45 version.
