WHAT'S NEW FOR 2027.
BMW 4 Series for 2027 largely carries forward the technology, design, and powertrain package introduced with the previous refresh.

The dashboard design with repositioned air vents also carries forward, providing personalized airflow for the driver and front passenger.
On the exterior, the kidney grille retains its high-gloss black frame treatment across the lineup, and vertical headlights define the daytime light signature. Rear taillights with high-precision laser technology are available on BMW 430i models and fitted as standard on BMW M440i models.
BMW 4 Series Convertible continues with its tailored soft top that opens and closes in approximately ten seconds at speeds up to 30 mph. A Convertible Wind Deflector is standard on open-top models.
MODEL LINEUP.
BMW 4 Series for 2027 spans three body styles, Coupe, Gran Coupe, and Convertible, across three engine families: BMW 430i, BMW M440i, and the BMW M4 range.
BMW 430i COUPE.
The entry point to the lineup. Rear-wheel drive is standard, with BMW xDrive all-wheel drive available as BMW 430i xDrive Coupe. Both share the 2.0-liter BMW TwinPower Turbo inline four-cylinder producing 255 hp and 295 lb-ft of torque.
BMW 430i GRAN COUPE.
BMW 430i Gran Coupe pairs the same 255 hp 2.0-liter BMW TwinPower Turbo four-cylinder with a four-door body and a fastback roofline. It seats five and offers a more accessible rear cabin than the two-door Coupe without moving to a full sedan profile. Rear-wheel drive is standard; BMW xDrive is available as BMW 430i xDrive Gran Coupe.
BMW M440i GRAN COUPE.
BMW M440i Gran Coupe brings the 386 hp 3.0-liter BMW M TwinPower Turbo inline six-cylinder with mild hybrid assist into the four-door fastback body. M Sport seats, standard laser rear lights, and BMW M-specific exterior details carry over from BMW M440i Coupe. BMW M440i xDrive Gran Coupe adds BMW xDrive all-wheel drive for those who want BMW M Performance output with all-weather traction in a four-door package.
BMW 430i AND BMW M440i CONVERTIBLE.
BMW 430i Convertible is offered in rear-wheel drive and as BMW 430i xDrive Convertible for those who want added traction confidence. Output remains identical to BMW 430i Coupe at 255 hp.
The same 386 hp six-cylinder is offered in open-top form. Rear-wheel-drive BMW M440i Convertible and BMW M440i xDrive Convertible configurations are both offered.
BMW M440i COUPE.
BMW M440i steps up to the 3.0-liter BMW M TwinPower Turbo inline six-cylinder with mild hybrid assist, producing 386 hp. It is available in rear-wheel drive or as BMW M440i xDrive Coupe. BMW M-specific exterior details, an M leather steering wheel, and standard laser rear lights separate it visually from BMW 430i.
BMW M4 COUPE.
BMW M4 Coupe starts at 473 hp from the high-performance 3.0-liter BMW M TwinPower Turbo inline six-cylinder, paired with a six-speed manual transmission and rear-wheel drive. BMW M4 Competition Coupe reaches 503 hp, and BMW M4 Competition xDrive Coupe tops the range at 523 hp with M xDrive all-wheel drive. All BMW M4 models arrive with Adaptive M Suspension, M Sport brakes, and BMW M-specific instrumentation.
BMW M4 COMPETITION xDRIVE CONVERTIBLE.
One open-top BMW M4 variant is offered: BMW M4 Competition xDrive Convertible, producing 523 hp and reaching 60 mph in 3.6 seconds. It includes M xDrive with an Active M Differential and ships with a tailored fabric top with silver accent threading.
THE BMW 4 SERIES GRAN COUPE: FOUR DOORS, FASTBACK PROFILE.
BMW 4 Series Gran Coupe occupies a distinct position in the lineup. It carries the low, sweeping roofline and rear styling of the two-door Coupe but adds two rear doors and a more practical rear seat. The result is a body that suits buyers who want BMW 4 Series aesthetics and need regular rear-seat access, without the packaging compromise of the Convertible or the footprint of a full sedan.
BMW 4 Series Gran Coupe offers a four-door fastback layout with frameless door glass and seating for five. The rear backrest folds to expand the load area when needed. Both BMW 430i and BMW M440i powertrain families are available in the Gran Coupe body, with BMW xDrive offered across both engine grades.
BMW 4 Series Gran Coupe does not offer a Convertible configuration. Buyers who want open-air driving can choose BMW 4 Series Convertible instead. For buyers balancing daily usability with BMW 4 Series visual identity, the Gran Coupe is the most practical body style in the range.
PERFORMANCE AND POWERTRAIN.
BMW 430i powertrains. The 2.0-liter BMW TwinPower Turbo inline four-cylinder produces 255 hp at 4,700-6,500 rpm and 295 lb-ft of torque from 1,600 to 4,500 rpm. An eight-speed automatic transmission is standard. BMW 430i Coupe reaches 60 mph in 5.6 seconds; BMW 430i xDrive Coupe does it in 5.4 seconds.

INTERIOR, COMFORT, AND CARGO.
BMW 4 Series Coupe and BMW 4 Series Convertible seat four passengers. BMW 4 Series Gran Coupe seats five. The two-door Coupe body provides a driver, front passenger, and two rear cabin occupants with purposefully bolstered Sport seats throughout the range. BMW M440i and BMW M4 models add M Sport seats with additional lateral support.
Cargo capacity behind the second row measures 10.6 cu ft in BMW 4 Series Coupe, expanding to 15.5 cu ft when the rear seat backrests are folded via the in-cargo lever. On BMW 4 Series Convertible models, cargo capacity with the roof up is 13.6 cu ft, reducing to 10.6 cu ft when the soft top retracts into its dedicated trunk compartment.
Interior customization spans multiple upholstery grades.

Ambient Lighting is standard across BMW 4 Series, giving the cabin a refined atmosphere after dark. The dashboard air vents contribute to the modernized cockpit aesthetic carried forward for 2027.
TECHNOLOGY AND INFOTAINMENT.
BMW Operating System 8.5 runs on a central display and is operated by touchscreen or the voice-activated BMW Intelligent Personal Assistant. Saying "Hey BMW" activates the assistant, which responds to commands for navigation, entertainment, climate, and vehicle settings, and learns preferences over time.
Wireless Apple CarPlay and Android Auto are standard. Wireless device charging is included. The My BMW App connects to the vehicle remotely for lock/unlock, Remote Engine Start, where equipped, and service scheduling.
Available packages expand the technology suite further. The Premium Package adds Remote Engine Start, a heated steering wheel, a power tailgate, Harman Kardon surround sound, and Live Cockpit Professional on BMW 430i models. The Parking Assistance Package includes Parking Assistant Plus with Parking View and 3D SurroundView, transmitting a 360-degree view of the vehicle's surroundings to the display during parking maneuvers.
On BMW M4 models, the BMW Curved Display integrates the instrument cluster and infotainment screen into a single arching panel, controlled by touch or voice. The BMW M-specific instrument display automatically adjusts its layout to emphasize performance information, navigation, or lap data based on the selected M Mode.
BMW ConnectedDrive integrates mobile devices, smart home technology, and the vehicle's intelligent systems into a unified driver environment. BMW ConnectedDrive features
SAFETY AND DRIVER ASSISTANCE.
Standard Driving Assistant on 2027 BMW 4 Series models includes three active systems:
- Active Blind Spot Detection
- Frontal Collision Warning with City Collision Mitigation
- Lane Departure Warning
Available packages add significantly to this foundation. The Driving Assistant Professional Package brings Traffic Jam Assistant, Distance Control with Steering Assistant, Lane Change Assistant, Emergency Stop Assistant, Evasion Aid, and partial automated hands-free driving at speeds up to 40 mph on selected highways. Availability varies by model and configuration.
BMW M4 Competition and BMW M4 Competition xDrive models add available driver assistance technologies through the applicable Driving Assistance Professional option package.
M Compound Brakes with red high-gloss calipers are standard on BMW M4 Competition models, providing performance-oriented braking capability. Adaptive LED headlights are standard on BMW M440i and BMW M4 models.
WHO IT IS FOR AND HOW THE 2027 MODEL COMPARES TO THE PRIOR YEAR.
BMW 4 Series for 2027 is built for drivers who prioritize a driver-focused body over a larger footprint. The three body styles, Coupe, Gran Coupe, and Convertible, give buyers a meaningful choice within the same platform. BMW 4 Series Coupe maintains its low two-door profile. BMW 4 Series Gran Coupe adds two rear doors and a fastback profile for buyers who need that access. BMW 4 Series Convertible delivers open-air driving with the same core powertrain families.
For 2027, BMW 4 Series largely carries forward the technology, exterior design, and powertrain updates introduced with the previous refresh. BMW Operating System 8.5 with QuickSelect, the revised dashboard layout, updated lighting treatments, and the current BMW 430i and BMW M440i powertrains continue into the 2027 model year rather than representing an all-new redesign.
Buyers comparing the 2027 model with the prior year will therefore find continuity in the core technology, design, and performance package. Those prioritizing maximum performance can step to BMW M4 Competition xDrive Coupe, which delivers 523 hp and reaches 60 mph in 3.4 seconds, or BMW M4 Competition xDrive Convertible, which reaches 60 mph in 3.6 seconds.
