Details and images of the new 2018 BMW X3 have been leaked ahead of the SUV’s official debut, by BMW Hong Kong. Besides giving us a preview of the new G01 X3, the leak also confirms the X3 M40i as the top model in the range, for now.

The X3 M40i is powered by a 3.0 litre turbo straight-six petrol engine with 360 hp and 500 Nm, paired to an eight-speed automatic and xDrive AWD. 0-100 km/h is done in 4.9 seconds, as with the X4 M40i. Top speed is electronically limited to 250 km/h. That’s good enough to beat the latest Audi SQ5, which makes 354 hp/500 Nm and does 0-100 km/h in 5.4 seconds.

The Hong Kong market will also get xDrive20d and xDrive30d diesel variants, with the M40i being the only petrol in the range. Fuel consumption and C02 emissions figures are lower across the board, attributed to reduced weight and better aerodynamics.

The M40i xDrive gets sportier M Performance suspension and steering, as well as a unique grey exterior colour option, 21-inch double-spoke M alloys and blue brake calipers. A leaked video hints at some sort of semi-autonomous system at play, with the driver shown taking his hands off the steering wheel.

Other features to expect from the G01 X3 include an auto opening tailgate triggered by a foot wave, a wide head-up display and rear seats that fold via button presses. An electric bicycle makes an interesting accessory to the midsize Sports Activity Vehicle.

As for the design of the new X3, it’s exactly like how we imagined it to look like – slotting in between the current X1 and X5 seamlessly, not just in size, but in looks as well. However, one sure way to spot the X3 is at the front – it lacks the round fog lamps on the bumper between the headlamps and the lower intakes, a signature that both the X1 and X5 sport.

Slightly less angular at the edges than before, but very much an upright, traditionally-shaped SUV (those who want a sportier image can opt for the X4), the new X3 looks very much like a larger scale X1, especially from the rear. However, the location of the rear reflectors follows the X5. Inside, the G01 is light years more modern than the F25, sporting a G30 5 Series-style driver-focused dashboard.
