BMW has unveiled facelifted versions of its X3 and X4 SUVs.
Among the changes for the closely-related models are the addition of 48V mild hybrid technology to all the petrol and diesel engine options in the ranges, allowing energy recuperation while braking and a power boost when accelerating.
The system is available with a choice of diesel engines producing 190hp, 286hp, and 340hp, and petrols producing 184hp (X3 only) and 360hp, while the X3 is also available as a 252hp plug-in hybrid, capable of an electric driving range of up to 31 miles on the WLTP cycle. All-wheel drive and eight-speed automatic transmission are both standard.
Preliminary fuel economy and CO2 emissions figures for the X3 are up to 48.7mpg and from 153g/km for the 190hp diesel, 45.6mpg and 160g/km for the 286hp diesel, 42.8mpg and 171g/km for the 340hp diesel, 37.7mpg and 175g/km, for the 184hp petrol, 32.1mpg and 204g/km for the 360hp petrol, and 141.2mpg and 43g/km for the plug-in hybrid.
Exterior styling changes to both models include a larger front grille and flatter headlights, while revised interiors feature a 12.3in infotainment touchscreen as standard, with new-generation sat-nav mapping, along with three-zone automatic air conditioning, and 40/20/40 split folding rear seats with adjustable backrests.
The updated X3 and X4 are available to order now, with prices starting at £43,370 for the X3 and £49,010 for the X4. The first UK customer deliveries are expected in September.
