How Accurate Are the Power Claims of Performance Cars?

TL;DR

The power output of four performance cars tested on the dyno varied significantly, with the Audi RS3 exceeding its manufacturer claim while the Mercedes A45S fell short by 35 horsepower. Weight measurements also differed from manufacturer claims, affecting the power-to-weight ratios, particularly for the BMW M240i, which showcased impressive torque despite a slightly lower power-to-weight ratio.

how much power do these four performance cars really make well to find out I'm going to put them on the dyno and compare the power output to what the manufacturers say they should make I'm also going to stick them on the scales to see how much they weigh and once again compare this figure to what the manufacturers say they should weigh are we going...
