Performance & specs
BMW has simplified its 1 Series lineup by ditching diesel engines, manual gearboxes and the ‘i’ tag. The hatchback is now only available in three specifications: the 120 Sport, 120 M Sport and M135 xDrive.
The 120 becomes the entry point into the 1 Series range. It’s powered by a 1.5-litre mild-hybrid three-cylinder turbocharged engine for 168bhp and 7.8-second 0-62mph sprint.
The new M135 utilises the same all-wheel-drive system as its predecessor but is slightly slower with 296bhp and a 4.9-second 0-62mph time. BMW says it has “significantly enhanced performance characteristics” due to its Adaptive M Chassis tech and sports steering setup.

Exterior & styling
Outside, you’ll notice that the 1 Series has replaced its classic kidney grille design. The new grille features a more modern blacked-out look with overlapping diagonal bars, while the sporty M135 xDrive has horizontal bars similar to other M models.
The nose of the new 1 Series is slimmer, cleaner and more angular than before with redesigned swept-back headlights and a more aggressive face.
At the back, you’ll find revised taillights and a tweaked bumper design. Standard models have no visible exhausts, whereas the M135 xDrive features a quad-exhaust layout.
The 1 Series retains its width (1,800mm) and wheelbase (2,670mm) but is 42mm longer (4,361mm) and 25mm taller (1,459mm). All models come with at least 17-inch wheels.

Interior & tech
Inside, the 1 Series has a huge, curved display that merges a 10.7-inch infotainment screen with a 10.25-inch digital instrument cluster.
Most physical controls, including the rotary knob, have been removed in favour of the upgraded infotainment system, which now includes the latest OS 9 software and Quickselect shortcuts for climate control adjustments.
The standard interior is leather-free, with new seats designed for long-distance comfort. A smaller gear selector replaces the traditional lever, giving the cabin a modern and minimalistic look.
Release date & pricing
The new BMW 1 Series is scheduled to go on sale in October with pricing starting at £29,959 for the 120 Sport, rising to £41,000 for the M135 xDrive hot hatch.
