BMW is giving the X3 M50 xDrive more muscle for the 2027 model year. The performance SUV's turbocharged inline-six now makes 437 horsepower, a jump BMW attributes to recalibrated engine software rather than hardware changes.
The automaker also confirmed a new Black Package for M Performance models, which now includes the X3 M50 xDrive itself. That raised fair questions about what exactly changed on the SUV and how the added output stacks up against the outgoing engine.
