BMW has revealed the second generation X4 coupe and it sits below the X6 and retains the rather coupe like design. The overall styling is sportier thanks to a larger grille and standard LED headlights. The dimensions on the X4 have changed and it is now 81mm longer, 37mm wider and 3mm shorter than before. The wheelbase has increased by 54mm. Interiors seemed to be inspired by the X3 and while a 6.5in infotainment system comes standard, a 10.3-inch unit is optional. It will come with 3.0-litre straight six petrol and diesel engines and the tried and tested 2.0-litre diesel will also be offered.
