BMW’s 2025 M2 and M4 share the same M-badge heritage yet deliver two distinct flavours of driver engagement from the moment the starter button is pressed. The compact M2 remains loyal to the old-school formula of rear-wheel drive and a choice of manual or eight-speed automatic gearboxes, channelling energy from a detuned 3.0-litre twin-turbo straight-six that produces 473 bhp. Its bigger brother, the M4, offers a broader repertoire: the same S58 engine in outputs up to 523 bhp, plus the option of rear-biased xDrive all-wheel drive for those who demand traction in any weather.

On paper, the differences are clear. The M2’s shorter wheelbase and lighter kerb weight make it feel alert as soon as the steering is turned, with an active M differential balancing playful oversteer against crisp corner exits. In contrast, the M4 behaves like a seasoned grand tourer when cruising, yet rockets to 62 mph in as little as 3.4 seconds in Competition xDrive guise, its adaptive suspension and five-link rear axle keeping the coupé composed when the road begins to twist.
Both cars clothe their mechanical muscle in unmistakably M styling cues, although each takes a separate route. The M2’s squared-off stance, modest kidney grille and flared arches give it the look of a tightly wound spring ready to pounce, while the M4 stretches out with a longer bonnet, sweeping roofline and those divisive vertical grilles that have become this generation’s hallmark. Quad tailpipes, vented bumpers and a carbon-fibre roof (on most M4 specifications) leave no doubt about performance intent, yet the smaller coupé’s compact dimensions lend it a more agile visual character.

Slide into either cabin and the driver-centric layout is unmistakable. The M2 offers supportive sports seats as standard, with optional carbon buckets for those who value weight saving over long-distance comfort. The M4 mirrors this arrangement but layers on greater customisation: additional trim finishes, Sensatec-wrapped dashboards and a wider palette of upholstery colours bring a touch of grand-touring polish. Both cockpits feature BMW’s latest curved display running iDrive 8.5, wireless smartphone mirroring, and a suite of driver-assistance systems that makes daily commutes almost effortless.
Choosing between the two depends on the flavour of M experience desired. The M2 provides a lively, rear-driven encounter that rewards precise pedal work and quick steering inputs, offering a raw connection that harks back to legendary M cars of decades past. The M4, meanwhile, blends muscle-car punch with continental refinement, delivering colossal pace when required while remaining composed and comfortable over long distances. Either way, BMW’s sporting siblings prove that the M division still understands how to create cars that stir the soul without compromising everyday usability.
