Report: The Volkswagen GTI apparently has underrated power figures

From an honest and scientific perspective, horsepower figures are usually approximations and don’t tend to be accurately described since the numbers usually published by the manufacturer are just peak horsepower numbers, without factoring the drivetrain losses and the actual figures that are produced at the wheels.

In some cases, like with BMW, this could be a good thing since BMW has a tendency to underrate their engines’ horsepower figures. This is learned through the classic method of the dyno test, where a car’s horsepower rating is measured at the wheels. Then some math is done to calculate how much power is actually being put down to the ground, versus what the engine is rated at. Some factors, such as an average 10 percent loss from drivetrain components, are crunched into these calculations.

And from this math, some can discover whether or not the factory horsepower ratings are accurate. As it turns out, similarly with BMW, the Volkswagen GTI’s power might be underrated from the factory. According to a private vendor, who posted on a Ford Focus ST enthusiast site, said vendor says they learned the Volkswagen GTI is capable of producing 263hp and 314 lb-ft of torque at the flywheel, which is a helluva lot more than the 210hp and 258 lb-ft figures from VW themselves. This is after factoring a 15 percent drivetrain loss.

Pretty damn impressive, if it’s accurate. However, this is one GTI example out of the many thousands of GTIs sold around the world, so this one test might not speak accurately for the GTI as a whole.

Let us know what you think about this find in the comments.
