The Mercedes AMG GLA 45 look pretty much identical to the previous model except for the new styling and paint scheme. Along with some minor cosmetic tweaks, now the cars come in a new stylish glossy black paint job with yellow highlights for the front and rear bumper, tyre walls, and in the case of AMG GLA 45 the rear spoiler as well. Additionally, there is a matte black racing stripe that runs along the hood, roof and boot, and AMG graphics on both sides above the side skirts, which enhance the sporty character of the cars. Furthermore, you also get Mercedes-AMG's customisation package.

Under the hood, the car pack the 2-litre Bi-Turbo petrol engine that comes mated to an AMG SpeedShift DCT 7-Speed sports transmission. The engine makes 375 bhp of power and a peak torque of 475 Nm. The engine also gets the assistance of Mercedes' highly capable 4Matic all-wheel-drive system. With the AWD system, the Mercedes-AMG GLA 45 can go from 0-100 kmph is 4.4 seconds.
