The BMW 1 Series (F70) is the fourth generation of the BMW 1 Series range of subcompact executive hatchback cars. Like the previous generation F40 1 Series, the F70 1 Series uses a front-wheel drive configuration and is only available as a 5-door hatchback.

Overview

The F70 1 Series was officially unveiled on 4 June 2024. It retains the UKL2 platform, which underpins F74 2 Series Gran Coupé. Production at the BMW Leipzig Plant commenced in July 2024 with a schedule market launch in October 2024.

The F70 1 Series is the first BMW model to drop the ‘i’ suffix for petrol models, to adapt with BMW’s strategy for using the ‘i’ prefix for battery electric models. The diesel models remains to be marketed with the ‘d’ suffix.

Compared to its predecessor, the F70 1 Series is 42 mm (1.7 in) longer and 25 mm (0.98 in) taller. The boot capacity is unchanged at 380 L (13 cu ft) with the rear seats raised, and 1,200 L (42 cu ft) with the rear seats folded. For the mild hybrid models, boot space decreased by 80 L (2.8 cu ft) to 300 L (11 cu ft) due to the placement of a 48-volt battery under the boot floor.

The exterior is an evolution of its predecessor being a heavy facelift of the F40 1 Series instead of a complete redesign. Exterior highlights includes the number ‘1’ in the Hofmeister kink C-Pillar trim piece when equipped with BMW Individual Shadow Line trim, LED taillights which has a similar shape from the X2 and the first BMW model to have a contrast roof option. Unlike newer BMW models, the F70 1 Series retain its conventional grab handles.

The interior is completely redesigned and has a similar layout to the X1 (U11). It features a BMW Curved Display which houses both the 10.25-inch digital instrument cluster and a 10.7-inch touchscreen infotainment system (powered by BMW Operating System 9) with QuickSelect functions. A gear selector switch is used for the automatic transmission instead of a gear lever and the number of physical interior controls has been reduced, including the omission of the iDrive control wheel (like on other entry-level BMW models).

The 1 Series is available with the latest generation of petrol and diesel engines borrowed from the X1 (U11), a plug-in hybrid option is not available for the 1 Series. All models come standard with a 7-speed Steptronic automatic transmission. For the first time in its history, the 1 Series will not be offered with a manual transmission.

M135 xDrive models features an Adaptive M Chassis with sport steering, an M Compound brake system with 385 mm (38.5 cm) front and 330 mm (33 cm) rear disc brakes available as part of the M Technology package and M Specific quad exhaust system. For Europe, the M135 is detuned to 296 hp (221 kW) due to strict European emission standards.
