Having recently tested the X3 20d, I assumed that the BMW X3 M50 would be that and then some, boy was I wrong. This buffed-up version of one of beemer’s best sellers is both a thrill and an experience to savour. A member of the G45 generation, it offers a combination of updated design elements, cutting-edge interior technology, and improvements in driving performance – it’s quite the ride.
The 2025 BMW X3 M50 highlights BMW’s evolving design language, which has sparked mixed reactions. The SUV has grown slightly, measuring 39mm longer and 23mm wider than before, contributing to a bulkier appearance, especially from the rear, which some liken to the shape of a ‘muffin on wheels’ – how rude. The new design definitely lacks the subtlety of earlier models, with a garish front grille and illuminated surrounds, however, on a positive note, the rear features a reintroduction of quad exhaust pipes, a nod to previous sportier models.
From a practical perspective, the side profile appears pleasing to the eye, and standout optional colours, such as Fire Red or in my case ‘Brooklyn Grey’, add vibrancy to the palette. The overall aesthetic, while polarising, improves in person compared to photos, with many suggesting it takes time to appreciate its modern design elements – I liked it straight away!
The interior of the X3 M50 sees significant updates compared to its predecessor, offering a more futuristic and tech-laden experience. BMW’s new iDrive 9 system debuts here, combining a physical control dial with a massive curved screen for enhanced usability. While this interface improves navigation, there is an abundance of glossy plastic surrounding the controls, which can feel cheap and act as a magnet for dust and fingerprints. The lack of tactile buttons in favor of touch-sensitive options also detracts from premium usability. But in saying that, the glam ambient lighting system showcases M colours, and that is NOT a bad thing.
Interior highlights include Improved seating, with the more bolstered and softer seats offer comfort for extended drives. Then there’s the technology upgrades. The high-definition heads-up display (HUD) is brighter and clearer than ever, sadly, ambient lighting does not extend to the rear seats. However, there’s heaps of space. Both passenger and cargo spaces are notably larger due to the increased wheelbase.
Despite these positives, certain cutbacks, such as a permanently closed panoramic moonroof, increased use of plastic materials, my spec had a hessian style dash finish and eliminated physical adjustments for vent controls (and over-engineered door vent) may disappoint long-time purists.
The X3 M50 comes equipped with the revered 3.0-litre B58 inline-six engine, now in its third iteration (TU3). Paired with a 48-volt mild-hybrid system, the powertrain generates 293kW ( 11 horses more than previous models) and a whopping 580Nm. The SUV sprints from 0–100kp/h in a brisk 4.6 seconds. Unfortunately, weight increases by 135 kg, (now at 1,980 kg), slightly dampers the benefits of the added performance.
While the engine remains inherently smooth and capable, many lament the loss of its signature exhaust character. Emissions regulations have led to quieter exhaust notes, and BMW compensates with artificial sound enhancements through the speakers (IconicSounds). Gone are the loud pops, crackles, and bangs that defined earlier versions, booo.
Power delivery is smoother and more linear in the M50, but it does lack the aggressive nature and responsiveness of the previous generation’s “Sports+” mode. Only “Sports” mode is available now, removing the sharper character that enthusiasts adored. On the plus side, BMW has greatly improved the steering, suspension, and overall handling dynamics. A wider rear track, increased chassis rigidity, and updated adaptive dampers result in enhanced agility and cornering stability. The improvements make the X3 M50 a pleasure to drive in twisty road scenarios or on long highway routes.
The new flat-bottomed steering wheel feels premium and precise, though there’s arguably more play compared to before, but on the move, particularly in “Sports” mode, the steering gives excellent feedback and weight. The new dampers expertly handle NZ road imperfections well, providing a smoother ride even on 21-inch wheels, a noticeable improvement over the older X3 models, and Noise, vibration, and harshness (NVH) are better controlled, creating a quieter cabin that enhances long-distance comfort.
Overall, while the X3 M50 retains its playful rear-wheel-drive-like dynamics in corners, the polished refinement means it feels more like a “professional racing horse” than the wilder and raw M40i it replaces.
The 2025 BMW X3 M50 is unmistakably an evolved product, offering a more polished, refined driving experience with some genuinely impressive features. However, its muted personality compared to the previous M40i may make it feel less visceral to enthusiasts. Its design remains polarising, and cost-cutting measures are evident in certain areas. That being said, I thoroughly enjoyed it – and I’m an enthusiast!
