The well-known tuner has approached the even more-known ladybug monster of a hatchback to increase its performance. Said and done, as the tuner managed to push this tiny car up to 518 Horsepower and a top speed of 201 mph.
The car will actually be adequate for the track, despite its past experiences on it and its remarkably small size compared to all the roadsters and supercars on the track these days, and it can even get better times than most of those, the main reason being that the car is very light.
German tuner Posaidon turns its attention to the Mercedes-AMG A45 for the RS 525 that pushes the output to 518 H.P. (386 kilowatts or 525 metric horsepower). With this huge boost in power, the new hatch will allegedly hit 201 miles per hour (324 kilometers per hour).
The RS 525 upgrade offers the A45 a distinct turbocharger, revised engine mapping, and software changes to the eight-speed dual-clutch transmission. After these changes, the overall output is 518 HP (386 kW) and 443 pound-feet (600 Newton-meters) of torque. As compared, a stock A45 S has 416 HP (310 kW) and 369 lb-ft (500Nm) of twist.
Posaidon estimates the RS 525 package lets the hatchback reach 62 miles per hour (100 kilometers per hour) in 3.4 seconds, versus 3.9 seconds in stock trim.
If you don’t feel snug making in-depth modifications like swapping out of the turbo, then Posaidon offers a version of this kit that solely involves software tweaks. With simply these changes, the A45 makes 459 HP (342 kW) and 413 lb-ft (560 Nm). Acceleration to 62 mph needs an estimated 3.6 seconds, and therefore the top speed is 198 mph (318 kph).
Posaidon is additionally teasing an even more powerful “Plus” tuning package that’s still in development. The company isn’t providing any details yet, however, it’s safe to guess that the output is even above 518 HP. The firm is additionally working on different performance improvements, like brake systems, exhausts, and carbon fiber wheels.
As a concept of what different tuners will do to the A45 and its siblings, Renntech offers kits that are capable of boosting the output as high as 592 HP all of that just by changing the turbo, exhaust, and engine control software. With no mechanical tweaks, the company will increase the figure to 469 HP (349 kW).
