When it leaves the factory, BMW claims the X3 M Competition (and X4 M Competition) produces 503 hp (375 kW) and 600 Nm of torque from a new twin-turbo 3.0-litre six-cylinder. Well, it seems they were quite conservative, at least according to a dyno run by IND.
It ended up producing 491 horses (366 kW) and 446 pound-feet (605 Nm) of torque at the wheels “on measly 89 Octane.”
At roughly ten percent drivetrain loss, it is estimated that the X3 M Competition actually pushes around 542 hp (404 kW) and 665 Nm of torque at the crank.
As a reminder, the X3 M Competition will start at R1,510,686, while the X4 M Competition will kick off at R1,605,686 making it almost R100k more expensive.
