BMW lifts the lid on range-topping X3 M and X4 M

BMW has revealed its high-performance X3 M and X4 M SUV models.

Priced from £77,070 and £79,990 respectively, the pair enter into the flourishing performance SUV segment, taking on the likes of Mercedes-AMG’s GLC 63.

Building on the X3 that was launched last year, the X3 M and mechanically identical X4 M will share a new twin-turbocharged six-cylinder engine.

The unit, which is 3.0-litres in capacity, produces 476bhp as standard, and 503bhp in range-topping Competition-badged versions.

However, UK buyers will only be able to opt for the Competition models.

BMW claims that the X3 M will go from 0-60mph in 4.0 seconds, while this time is shaved down to 3.9 seconds in the more powerful Performance version.

Torque for both sits at 600Nm, and power is sent to all four wheels via BMW’s xDrive system through an eight-speed M Steptronic gearbox. Though drive is sent to all wheels, it’s been developed with a torque and power bias to the rear axle.

Alongside the new engine, BMW has fitted the X3 M with a range of chassis tweaks to ensure it’s as capable in the corners as it is fast on the straights. New front and rear subframes have been installed, alongside with additional bracing across the front suspension.

New 21-inch twin-spoke alloy wheels differentiate the M from the rest of the X3 range, and these are joined by an M sport exhaust system and M compound brakes in a list of performance additions.

Visual enhancements include oversized front bumpers, redesigned side skirts and a new roof spoiler. Competition models also benefit from black gloss grilles, mirror caps and front wings, too.
