Spot the new rear diffuser and spoiler.
The photo reveals the M badge on the liftgate positioned above the taillights. The standard BMW X4 has the badge below. The rear diffuser is new, making room for the larger circular quad exhaust, and there's a small lip spoiler on the edge of the trunk. The X4 M borrows the same side-view mirror design as the X6 M. It's difficult to tell if the wheels are unique in the photo; however, they should be 21 inches in size.
A biturbocharged 3.0-litre straight-six engine from the M3 and M4 should power the X4 M. BMW hasn't confirmed this. The engine should deliver around 475 bhp. The X4 M will receive a lower ride height, larger wheels, stickier tyres, and larger brakes. This should improve the crossover's handling.
Inside, upgrades over the current range-topping X4 M40i will likely be minimal. Expect Alcantara upholstery and carbon fibre trim.
The standard X4 arrives in the UK this summer, and the range will start at £43,000. The BMW X4 M will slot below the 567 bhp X5 M in BMW's portfolio. The BMW X4 M should debut before the end of the year and go on sale in 2019.
We should know details about the X4 M later this year at its unveiling, including its performance. Pricing may come then. However, BMW could wait until closer to the crossover's arrival at dealerships to confirm the starting price. There should be several optional packages available.
