The car's larger dimensions (length + 93 mm, wheelbase + 50 mm) mean that rear passengers can now enjoy extra legroom. Behind the fully contoured front seats, 15 millimetres of additional knee room and eight millimetres of extra headroom further enhance the passengers' comfort on the road. Backrest nets available as an option as part of the storage package offer additional accommodation for small items, reflective vests and road maps. Larger pockets in the front doors, whose lines and surfaces open up towards the instrument panel, now have space for drinks bottles up to one litre in size. Added to which, two large drinks holders are now integrated into the centre console ahead of the gearshift lever. If desired, the cupholders can be swapped for an oddments tray, which is stored in a designated area of the glove compartment when not in use. The new sedan offers 480 litres of boot capacity, 20 litres more than the outgoing model. And an innovative and practical solution allows extremely convenient access inside. If the optional Comfort Access is specified, the boot can be opened hands-free and without needing to use a key: all you need to do is move your foot around underneath the bumper to trigger the opening mechanism for the boot lid (see also BMW ConnectedDrive). He can then comfortably load as much as seven standard crates of bottled drinks, three golfbags or a pram over the boot sill, which is a mere 66 centimetres high (just under 26 in.). Standard-fitting securing lugs hold the items firmly in place, while a storage tray under the load compartment floor and a deep storage compartment on the left-hand side accommodate small oddments. For bulky items, the optional through-loading facility includes a folding rear seat bench to allow flexible transport solutions. The 40:20:40 split rear backrests offer unbeatable versatility when you need to carry passengers and long items, such as several pairs of skis or snowboards, at the same time. (A matching BMW ski/snowboard bag is available from the BMW Accessories range).
