Mercedes-AMG A45 S Drag Races CLA 45 S With ECU Tune

We’ve observed the Mercedes-AMG A45 S against numerous various opponents on the drag strip. From time to time it wins, and from time to time it doesn’t. But today’s race that includes the extremely-warm hatch has a a bit various function – to show what a basic Ecu remap can do to an currently incredibly able device.

Carwow took a yellow A45 S and put it following to a tuned CLA 45 S. The latter has a new engine regulate application and pushes out – behold! – 490 horsepower (365 kilowatts) and 487 pound-toes (660 Newton-meters) of torque. And certainly, there are no components modifications to the tiny 2.-liter four-banger below the hood. 

On paper, this in all probability seems like a waste of time. In stock sort, the A45 S has 421 hp (314 kW) and 367 lb-ft (five hundred Nm) of torque, properly down below the figures of the tuned CLA. But then, the track is damp and electrical power is naturally not every thing. Traction is the search term right here and it decides the standing-get started drag race.

With so a great deal further electrical power and an indecisive transmission, the remapped CLA struggles to channel its electrical power to the highway. In the 1st race, the A45 S takes a comfortable win many thanks to its greater traction. In the next run, we have the same winner, although this time around it’s a photograph finish.

However, the upgraded CLA exhibits its complete opportunity in the rolling race exactly where it annihilates the yellow warm hatch. And if you want our two cents, this is the far more significant duel right here as it exhibits that a established of greater tires and nicer weather conditions could do miracles with the overall performance sedan from Stuttgart. Just really don’t drag race it when it rains.
