BMW has taken the wraps off its new, second-generation X4, with the coupé-style SUV growing appreciably in size and the line-up gaining a pair of "M Performance" models.

Based on the latest G01-generation X3, the new X4 is 81 mm longer and 37 mm wider than the model it replaces, while its wheelbase has been stretched a further 54 mm to 2 864 mm. Load space can be expanded from a claimed 525 litres to a maximum of 1 430 litres by folding down sections of the rear backrest (which is split 40:20:40).

The new X4 is scheduled to arrive in South Africa in the third quarter of 2018. Customers will have the choice of xLine, M Sport X and M Sport variants.

BMW says buyers will be able to choose from three petrol and four diesel engines, although South Africa will miss out on one engine option, with the local range set to initially comprise the xDrive20i, xDrive20d, xDrive30i and M40i. The xDrive30d is due to arrive in the final quarter of 2018, with the M40d joining the range in the first quarter of 2019.

The X4 M40i employs a six-cylinder inline petrol unit turbocharged to produce 265 kW and 500 N.m, which BMW says is enough for a 0-100 km/h sprint in 4,8 seconds. The M40d draws 240 kW and 680 N.m from its straight-six diesel heart, completing the obligatory dash to three figures in a claimed 4,9 seconds.

The six-cylinder, oil-burning xDrive30d makes 195 kW and 620 N.m, while the xDrive25d is the single engine derivative not destined for local shores. The 2,0-litre, four-cylinder xDrive20d is worth a diesel-flavoured 140 kW and 400 N.m, while the petrol-powered xDrive20i and xDrive30i (both four-pots) make 135 kW/290 N.m and 185 kW/350 N.m, respectively.

All models employ an eight-speed Steptronic transmission (with shift paddles) and xDrive all-wheel drive as standard. The M Performance derivatives furthermore come equipped as standard with 20-inch light-alloy wheels, M Sport brakes and an M Sport differential.
