# BMW 1 Series (F40)

The BMW 1 Series (F40) is the third generation of the BMW 1 Series range of subcompact executive hatchback cars. Unlike the previous generation F20 1 Series, the F40 1 Series uses a front-wheel drive configuration and is only available as a 5-door hatchback.

## Overview

The F40 1 Series premiered at the 2019 Frankfurt Auto Show and launched on 28 September 2019. Built on the UKL2 platform, it shares the same front hood, fender panel, dashboard, and suspension as the 2 Series Gran Coupé.
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. 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). 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. The F40 1 Series is also 30 kg (66 lb) lighter due to increased use of aluminium.
Petrol engines have a gasoline particulate filter, while diesel engines feature a diesel particulate filter and AdBlue selective catalytic reduction. All engines meet the Euro 6d-TEMP emissions standard.
118i, 116d, and 118d models come with 6-speed manual transmissions as standard. 118i and 116d models can be specified with a 7-speed Getrag 7DCT300 dual-clutch transmission, while an 8-speed Aisin automatic transmission is available for M135i xDrive, 128ti, 118d, and 120d xDrive models.

European models feature collision detection and lane departure warning with intervention as standard.
The F40 1 Series is available with iDrive 7.0 with two 10.25-inch displays. iDrive 7.0 features the voice-controlled BMW digital assistant which can control in-car functions and can be activated by saying "Hey BMW". 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. The digital key can also be shared with up to five other smartphones.
Other options include gesture control, a windshield reflected head-up display, automatic parking, a panoramic sunroof, Apple CarPlay and Android Auto.
M135i xDrive models feature a limited slip differential, larger M Sport brakes, a strut bar, and a larger 100 mm (3.9 in) diameter exhaust.

## 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.
