What is it?
Naturally this raised an eyebrow or two at Stuttgart, so action had to be taken. Along with flipping the name to read AMG A 45 – in line with current AMG naming policy – a significant hike in power to 376bhp means it’s back to being the most powerful hot-hatch in town.
This boost, plus closer gear ratios and quicker shift times from the seven-speed dual-clutch transmission, drop the 0-62mph time to just 4.2sec, which just happens to be 0.1sec quicker than the RS3.
You also get a Dynamic Select switch that, like the similar ones in the AMG GT and AMG C 63, allows you to switch the driving modes between Comfort and Sport+ depending on your mood.
If you specify the optional new AMG Dynamic Drive package, this adds an even sharper Race mode, along with adaptive dampers and a mechanical limited-slip front differential – aimed at improving traction out of bends and stability during high-speed manoeuvres.
Visual changes are subtle but include new LED headlights and restyled front and rear bumpers. Along with a new rear diffuser, the bodywork changes are claimed to clean up the airflow around the car thereby reducing drag, as well as boosting downforce.
Inside, it has an 8.0in infotainment screen and sat-nav, but if you go for the optional COMAND system this adds Apple Carplay and Mirrorlink, plus online connectivity.
