We’ve witnessed the Mercedes-AMG A45 S from numerous diverse opponents on the drag strip. At times it wins, and from time to time it does not. But today’s race featuring the extremely-sizzling hatch has a a little bit diverse intent – to demonstrate what a uncomplicated Ecu remap can do to an previously incredibly able device.

Carwow took a yellow A45 S and place it future to a tuned CLA 45 S. The latter has a new engine command software and pushes out – behold! – 490 horsepower (365 kilowatts) and 487 pound-ft (660 Newton-meters) of torque.
