Affalterbach - Mercedes-AMG is pushing the four-cylinder boundaries even further with its new-generation A45.
Although the range-topper has yet to be officially revealed, the boys in Affalterbach have officially announced the power and torque outputs for its newly-developed 2-litre engine, codenamed M 139.
Like its predecessor the new motor will have the distinction of being the most powerful series production four-cylinder engine in the world, just by a much bigger margin, with up to 310kW and 500Nm on command, which is 30kW and 25Nm more than before.
Those outputs apply to the A45 S model, which is being offered for the first time, and Mercedes-AMG will still offer a regular A45, with 285kW and 480Nm.
Just think about that for a moment. It wasn’t too long ago that 300kW was extremely impressive for a V8 motor.
