This Is How Much Power The G80 M3 Competition Actually Makes

Video / Comments

It's a healthy little guy

We know what the BMW G80 M3 Competition looks like, We've seen the color options, BMW has explained to us how the aerodynamics function, and we understand how M Mode works, but there's one little thing that we need to know: how much power does the new G80 M3 competition really make.

We all know the drill; manufacturers come out with a new performance model that feels much faster than the factory power figures suggest. Plop said car on the rollers and low and behold, the car makes more power than what is officially stated. Now it's the G80 M3 Competition's turn, and we suspect that the numbers are going to be impressive.

In a video posted to YouTube by Evolve Automotive we get to see a stock standard G80 M3 Competition on the rollers. This brand new car has had its break-in service done, so any horsepower that was hiding in the creases have now been released (although we think a few more will make themselves known as the car puts on the miles).

The G80 M3 Competition is powered by the S58 twin-turbo inline-six engine borrowed from the X3 M and X4 M. In standard guise it puts out 473 horsepower and 406 lb-ft of torque which is 48 hp more than the outgoing model. In Competition configuration, it makes an even more impressive 503 hp and 479 lb-ft of torque according to BMW. So how does it fair on the dyno?

It should be noted that the test car runs 92/94 octane fuel. On its first two runs the car is tested in RWD config and in dyno mode. The figures: 469 hp and 434 lb-ft of torque. So it turns out that the car didn't make the factory quoted power, though the official numbers are measured at the crankshaft and not the wheels. It did beat it's advertised torque figure, by a wide margin.

Of note, a stock F80 M3 makes 421 hp at the wheels (425 hp advertised), and an F80 with a stage 2 tune makes around 480 hp at the wheels on the same dyno. We'll give it five seconds before the G80 is offered with a hybrid turbo kit that pushes out over 700 hp. Chasing horsepower is too easy these days.
