BMW 1 Series (F70) – Model Year 2025


Country of manufacture

Every new-generation 1 Series is assembled in BMW’s Leipzig and Regensburg plants in Germany; additional capacity for CKD kits is planned for Araquari (Brazil).


Snapshot

Entering its fourth generation, the 2025 1 Series gains a sharper, arrow-DRL front end, a flatter, diagonally-barred kidney grille and smoother bumpers that cut drag to Cd 0.26. A contrasting black roof is offered for the first time.
Inside, the premium-compact hatch adopts BMW Operating System 9 on the Curved Display (10.25-in cluster + 10.7-in infotainment) with QuickSelect tiles and an optional AR head-up display. A leather-free cabin, recycled Econeer fabrics and over--the-air upgrades underline the car’s sustainable brief.
The chassis features stiffer mounts, recalibrated dampers and a 20 % increase in front-wheel caster; Adaptive M suspension (-8 mm) and M Sport brakes remain optional.

Luggage space

380 l (seats up) / 1 200 l (folded). On 120/120d mild hybrids the rear floor remains level; no capacity loss.


PROS

StrengthWhy it matters
Sharp handling50 mm wider track, variable-ratio steering and optional Adaptive M keep the 1 Series the driver’s choice in its class.
Modern cockpit techOS 9 Curved Display, QuickSelect shortcuts, 5 G eSIM and natural-speech “Hey BMW” voice control.
48 V efficiencyMild-hybrid petrol and diesel units deliver sprightly response yet dip below 5 l/100 km on motorway runs.
Level 2 ADASStandard Driving Assistant & Parking Assistant with Reversing Assist; optional Steering & Lane Control up to 210 km/h.
Practical hatchback40/20/40 rear backrest, flat load floor, under-floor storage for charging cables or tyre kit.
Resale securityFleet guides forecast 65-68 % residual for 120d and M135 after 36 months.

CONS

Weak pointDetails
No manual optionAll models now use the 7-speed dual-clutch—some purists will miss the six-speed stick.
RWD platform goneFront-drive layout means torque-steer under full throttle on the 300 hp M135 if roads are bumpy.
Firm ride on 19-in wheelsThe optional 235/35-19 tyres amplify potholes; stick to 18-inch for comfort.
Limited battery techUnlike rivals, no PHEV or full-electric version until 2026.
High option pricesHarman Kardon audio, panoramic roof and Driving Assistant Professional can add €8–9 k to a base 120.
Small rear door openingTapered C-pillar narrows access for child-seat installation.

Bottom line

The 2025 BMW 1 Series pushes the premium hatchback envelope with OS 9 tech, standard mild-hybrid power and trademark chassis poise. It sacrifices rear-wheel-drive purity and adds heft, yet remains the segment’s most engaging all-rounder—especially in 300 hp M135 guise—while base models deliver genuine 5 l/100 km economy and everyday practicality.

Verdict — BMW 1-Series (F70 MY 2025)

The fourth-generation 1-Series (code F70) ditches six-cylinder power but gains sharper styling, optional Iconic Glow headlights and a 10.7-inch Curved Display running iDrive 9. Built on an updated FAAR platform, it offers variable steering and 48-V mild-hybrids across the board, topped by the new M135 xDrive with 300 hp. Up against the Audi A3, Mercedes A-Class, VW Golf VIII and Peugeot 308, the 1-Series leans on driving engagement and up-to-date digital tech while keeping everyday hatch practicality.
