The dimensions of the five-door model have changed only slightly compared to its predecessor. The exterior length of the new BMW 1 Series has increased by 42 millimetres to 4,361 millimetres, while the wheelbase is 2,670 millimetres. The vehicle width is 1,800 millimetres, while the height has increased by 25 millimetres to 1,459 millimetres.

The wide, forward-leaning BMW radiator grille features an innovative structure of vertical and diagonal bars. The standard LED headlights feature striking vertical elements for the daytime running light and the turn indicators. Towards the sides, the dynamic wedge shape and the flat window graphics that taper towards the rear, standard BMW Individual high-gloss Shadow Line, a long roof spoiler and side air deflectors are a part of the package.
