2019 BMW X3 M and X4 M unveiled

2019 BMW X3 M and X4 M unveiled news

BMW’s mid-sized SUV twins get the go-fast treatment

BMW has officially revealed the newest members of the M family, the mid-sized X3 M and X4 M SUVs, with power figures that outgun some of M Division’s finest, and styling that seems to lean towards the subtle side.

With a new 3.0-litre twin-turbo inline six, the BMW X3 M and X4 M both produce 353kW and 600Nm, more than any other six-equipped M car.

BMW says they’ll hit 100km/h in just 4.2 seconds, but that there will also be Competition variants with an extra few kiloWatts (for a total of 375kW) allowing a 4.1 second 0-100km/h sprint.

Helping this is a slightly wider torque band in the Competition models. In standard spec, the X3 M and its X4 companion reach peak torque between 2600 and 5600rpm, while the Competition’s peak torque drops off only after 5950rpm.

Peak power delivery arrives at a high 6250rpm, and carries through to the 7200rpm redline in both versions of X3 and X4 M.

Interestingly, BMW says the core of its cylinder head in the new engine has a 3D-printed core, which allows a more complex construction than conventional manufacturing.

“3D printing technology has cut the weight of the new engine’s cylinder head core and allowed its coolant ducts to be routed in a way that optimises temperature management.”

The engine sends power to all four wheels with a rear-bias as in the BMW M5, via an 8-speed M Steptronic automatic transmission. BMW says the gearbox  give drivers enough control in manual mode that it’ll allow the tacho to reach redline and won’t automatically upshift once it’s there.

Both versions of each model come with BMW M-tuned adaptive dampers as standard, and while BMW doesn’t specify, it wouldn’t be a surprise if the Competition variant has a slightly stiffer bias.

M Division has stiffened up the chassis of each with elements like engine bay bracing made from carbon fibre reinforced plastic, while the Competition versions gain extra custom custom-made swivel bearings, torque arms, wishbones, and model-specific anti-roll bars.

While BMW’s M cars are rarely visually raucous, the X3 and X4 M models have remained relatively subtle with only small accents such as lip spoilers and their badging to give the game away. An optional M Carbon exterior package will be available about mid-year for those who wish to change this.

Seven colours are to be available, ranging from the subtle M-exclusive Donington Grey, to brighter hues such as Toronto Red metallic.

Inside, all the usual M car elements can be found, including an M steering wheel, carbon fibre trim, an M instrument cluster, and the new M1 and M2 buttons fitted to the wheel allowing easy access to customised drive settings.

Local pricing and availability for the X3 M and X4 M is yet to be confirmed by BMW Australia.
