Here's Proof New BMW M3 Will Have Well Over 500 HP

Video / 4 Comments

BMW X3 M Competition showed a jaw dropping 509 horsepower.

BMW has a long history of underrating power produced from its cars, and it looks like the X3 M follows that finest of Bavarian traditions. To demonstrate just how much though, IND Distribution has videod a BMW X3 M Competition making a dyno pull. When you've seen one dyno pull video you've seen them all, but there is a moment in there that will widen your eyes. BMW rates the X3 M Competition at 503 horsepower from the crankshaft. At the end of the video, we see that the Bavarian powerhouse of an SUV is making 491 horsepower at the wheels, so that's after any drivetrain loss.

Generally speaking, the conservative estimate for drivetrain loss is around 10%. Doing the math, that would put the BMW X3 M Competition at 542 horsepower from the crank at least.

But how does that relate to the upcoming M3 mentioned in the headline? Well, it's the same B58 inline-six that's expected to power BMW's pumped up 4-door sedan when it arrives. BMW's head honcho, Markus Flasch, recently revealed that the M3 would come with 480 or 510 horsepower, and we assume it'll be the M3 Competition that will crank the most ponies. If this dyno'd X3 M Competition is anything to judge by, it'll be more than BMW claims.

We don't know a huge amount about the next M3 yet other than that it'll have a manual transmission available in the standard model for the purists that want to row their own. The hardcore M3 Competition should have an all-wheel-drive system similar to the current M5 that can also switch to rear-wheel-drive for some full-on tire hating at the track.

The M3 in development has been spotted by our spy photographers recently, which also suggests it will debut soon. We don't expect to see it on dealer's lots until 2020 alongside the new M4 as 2021 models.
