2025 BMW 4 Series: What's New, Specs & Features
Last updated August 4, 2026
The 2025 BMW 4 Series gets a mid-cycle refresh, led by revised lighting and grille details, updated cabin technology, and mild-hybrid powertrain changes. Its basic lineup and rear-drive-based layout remain the same.
About the 2025 BMW 4 Series
2nd generation 4 Series (G22 coupe, G23 convertible, G26 Gran Coupe), mid-cycle refresh year.
BMW positions the 4 Series as the more emotional, style-forward sibling to the 3 Series. It is a compact luxury car range built around bold design, strong turbo power, and a driver-focused cabin with BMW’s curved display. The coupe and convertible lean hardest into sleek looks and open-air fun, while the Gran Coupe adds useful rear-seat and cargo access without losing the fastback shape. The common thread is sporty character first, practicality second.
The 430i is the balanced, efficiency-minded version, with a 255-hp turbo four-cylinder, sport seats, and a curved digital display; xDrive versions add all-wheel drive. The M440i is the stronger performance step, using a 386-hp turbocharged inline-6, while the four-door Gran Coupe adds rear-seat access and a more useful cargo opening.
What changed, by category
Powertrain
The 430i models gained 48-volt mild-hybrid assistance. The M440i models received an updated mild-hybrid turbocharged inline-6 rated at 386 horsepower and 398 lb-ft of torque, up from 369 lb-ft.
Styling
BMW revised the grille, slim LED headlights, and rear lighting. M440i models gained laser-style taillights, while the cabin received new steering wheel designs and revised air-vent and climate-control details.
Tech
BMW Operating System 8.5 with QuickSelect arrived across the lineup. Heated front seats became standard on the 430i, 430i Gran Coupe, 430i xDrive, 430i xDrive Gran Coupe, M440i, and M440i xDrive; the M440i and M440i xDrive also made a heated steering wheel and remote start standard.
