The X3 gains a new front April, raised underbody protection and window graphics and roof rails finished in aluminium. The rear styling has been reworked with larger exhaust pipes and narrower rear lights.
The styling of the X4, which is 43mm longer than the X3 and sits 55mm lower, has been reworked to emphasise its more ‘sporty’ coupe-esque styling. That includes the revised grille, and a revamped rear engine design.
Both models will be offered in M Sport trim, which adds a mesh kidney grille with black gloss surrounds, along with extra gloss exterior trim and M Performance aerodynamic styling.
In the UK, 19in wheels will be standard, with the M Competition versions sitting on 21in alloys.
The interior styling has been revamped with a new centre console taken from the latest 4 Series, with a central display built around a 12.3in touchscreen. Enhanced sports seats are available, and M Sport models feature leather upholstery as standard.
The petrol and diesel line-up for both models has been revamped, with 48V mild-hybrid or plug-in hybrid on all powertrains.
Three diesel engines will be offered on both models: the 187bhp xDrive20d, 282bhp xDrive30d and 335bhp M40d.
The X3 will be offered with the petrol-engined 177bhp xDrive20i and the 249bhp xDrive30e plug-in hybrid, which can complete up to 31 miles of electric-only running.
