Compared to its predecessor, the F40 1 Series is 5 mm (0.2 in) shorter, 34 mm (1.3 in) wider, and 13 mm (0.5 in) taller.[6] Despite the decreases in length, due to the tighter packaging of the front-wheel drive engine, front legroom has increased by 42 mm (1.7 in), rear legroom has increased by 33 mm (1.3 in), and rear headroom has increased by 19 mm (0.7 in).[7] The boot capacity has also increased by 20 litres (0.71 cu ft) to 380 litres (13 cu ft) with the seats raised, and 1,200 litres (42 cu ft) with the seats folded.[8] The F40 1 Series is also 30 kg (66 lb) lighter due to increased use of aluminium.[9]
The F40 1 Series is available in Advantage, Luxury, Sport, and M Sport trim.[14] Sport and Luxury models feature an M Sport Steering wheel, while M Sport models feature sport seats and M exterior styling.[15] European models feature collision detection and lane departure warning with intervention as standard.[16]
The F40 1 Series is available with iDrive 7.0 with two 10.25-inch displays.[17] iDrive 7.0 features the voice-controlled BMW digital assistant which can control in-car functions and can be activated by saying "Hey BMW".[18] A digital key also enables the vehicle to be unlocked using near-field communication by holding a smartphone near the door handle and the engine can be started by placing the smartphone in the wireless charging tray.[19] The digital key can also be shared with up to five other smartphones.[20]
116-120 models with M Sport and 128-M135 models can be fitted with M Performance Parts. These include canards, a spoiler, a splitter, side skirts and rims. 116-120 models without M Sport can still be equipped with the M Performance rims and spoiler. However, to install the rest, they need to be converted to M Sport with the M Sport bumpers and trims. The M135i grille can be fitted to all F40 1er models.
Updates
In October 2021 BMW revealed an updated M135i. It comes with retuned springs, dampers and trailing arm and control arm mounts. A hydromount was also added to attach the front wishbones and the camber has been increased for more grip. The artificial interior engine sound was loudened as well.[23]
