Yet another tuned ladybug sized car, while despite its size the car can output way more than anyone would think or hope it would, as you can see in the video bellow, the tiny vehicle is rushing on the unrestricted autobahn with no regret whatsoever.
Its size and weight are the main reasons why the car can output so much power out such a small engine, along with all the software tunes done by RaceChip, reaching up to 124 MPH with ease.
The Mercedes-AMG M139 2.0-liter turbocharged four-cylinder is an absolute jewel of an engine due to its wonderful output of 416 H.P. (310 kilowatts) and 369 pound-feet (500 Newton-meters). A noteworthy new video from the German tuner RaceChip offers a review of the mill in the A45 S and offers some insight into what’s necessary to spice up the output even higher.
RaceChip’s tune pushes the engine to 484 HP (491.1 ps or 361 kW) and 399 lb-ft (540.9 Nm) of torque. The dyno shows this setup making 400 HP (405.3 ps or 298 kW) at the wheels, which equates to a driveline loss of 17.47 percent. RaceChip takes the upgraded hot hatch to the autobahn and finds that it will go from 62 miles per hour to 124 mph (100 km/h to 200 kph) in 9.16 seconds.
Even before the tune, the 2 guys from RacingChip have for the most part positive things to mention concerning the A45 S. Despite having a huge turbo, the engine is quite responsive. One drawback is that it doesn’t sound quite as mean as the previous generation of the new hatch.
RaceChip charges €699 ($751 at current exchange rates) for this upgrade. There’s additionally a lesser version that adds 58 HP (43 kW) and 24 lb-ft (33 Nm) for €399.
If you would like even more power from an A45 S then the folks at Renntech will help. The company will boost the output as high as 592 HP (442 kW). This needs fitting a modified turbocharger, exhaust, and engine software.
While the A45 S isn’t coming back to the united states, Americans eventually get the M139 engine within the CLA 45 sedan and GLA 45 crossover.
