title：BMW X3M & X4M Competition: Road & Track Test Review

content：BMW X3M & X4M Competition: First-Hand Road & Track Review

For years, BMW M division’s move into SUVs has split fans: Should M stick to sports cars or embrace practical performance? If you’re on the fence about the X3M and X4M Competition, our first-hand road and track test will clear things up. We drove both models to see if they live up to the M badge—and what makes them stand out from rivals like the Porsche Macan or Jaguar F-Pace SVR.

The Heart of the M: 3L Twin-Turbo Straight 6 Engine

The X3M and X4M Competition are the first M cars to get BMW’s all-new 3-liter twin-turbo straight 6. With 503 brake horsepower and 443 lb-ft of torque (the most ever from a petrol straight-6 BMW), this engine is a game-changer. On the road, it feels responsive—peak power hits above 6,000 RPM, and it revs to 7,200 RPM, giving it a free-revving character you don’t always get in turbo SUVs.

The exhaust note is a subtle twist on the classic M straight-6 sound—convincing enough, even if some of it comes from the stereo (a common trick these days). 0-62 mph takes just 4.1 seconds—quicker than most rivals, though not the fastest in class. But raw speed isn’t everything; the engine’s linear power delivery makes it easy to control on both road and track.

Handling & Drivetrain: Balancing SUV Practicality & M Performance

BMW’s M division didn’t just drop a powerful engine into an SUV—they tweaked every part of the drivetrain and suspension. The adaptive sports suspension (with 5 steel coils and adaptive damping) keeps body roll in check, even on twisty roads. The M xDrive system (same as the M5’s) sends power to all four wheels, but sport mode biases it toward the rear for a more engaging feel. Unlike the M5, there’s no 2WD mode—BMW figured SUV buyers want all-wheel drive always, which makes sense.

On the track (we tested the X4M at Silverstone), the car feels balanced. The active rear differential helps with cornering, and the 8-speed torque converter shifts quickly (though not as snappy as a dual-clutch). The steering has plenty of weight, making it feel like a proper M car—just jacked up. The only downside? It’s not as comfy as some rivals; the suspension can feel stiff in sport mode, especially on rough roads.

X3M vs X4M: Which One Fits You?

The X3M and X4M Competition are almost identical mechanically. The X4M is slightly lower and lighter (by a small margin), which gives it a marginally sportier feel on track. But the X3M has more practicality—its boxier shape means more rear headroom and cargo space.

If you want a balance of performance and family-friendly space, go for the X3M. If you prefer a sleeker, coupe-like look and don’t mind losing a bit of space, the X4M is your pick.

Toolbox for Potential Buyers

Actionable Checklist:

1. Test drive both the X3M and X4M to feel the space vs. style trade-off.
2. Try sport mode on twisty roads to see if the suspension stiffness works for you.
3. Ask the dealer about track day experiences if you plan to take it to the track.

Final Verdict

The BMW X3M and X4M Competition are solid choices for M fans who want SUV practicality without sacrificing performance. The new engine is a standout, and the handling is better than most performance SUVs. It’s not perfect—comfy isn’t its strong suit—but it’s a true M car at heart.
