BMW 4 Series Convertible: Price, Specs & Review
The BMW 4 Series Convertible is a compact luxury four-seat convertible for buyers who want open-top driving without giving up modern performance, premium technology, or everyday comfort.
For 2027, the range starts with the 255-hp 430i and moves up to the 386-hp M440i. Both are offered with rear-wheel drive or BMW xDrive all-wheel drive. A fabric soft top replaces the Coupe’s fixed roof, giving the car a more relaxed, experience-led personality while adding cost, weight, and some practicality compromises.
It is best for couples, weekend trips, and drivers who genuinely value roof-down motoring. It is not the right pick for frequent rear-seat passengers, large luggage needs, or buyers seeking low ownership costs.
WheelPedia Rating: 8.1/10
The BMW 4 Series Convertible earns an 8.1/10 WheelPedia Rating. It has strong powertrain choices, polished road manners, a well-finished cabin, and one of the better soft-top systems in the luxury segment.
It loses points for its high price, limited rear-seat room, reduced trunk space with the roof lowered, and expensive long-term ownership.

About the BMW 4 Series Convertible
The BMW 4 Series Convertible is the open-top version of the BMW 4 Series Coupe. It shares the Coupe’s basic shape, engine lineup, technology, and rear-wheel-drive-based architecture, but replaces the fixed roof with a power-operated fabric soft top.
The soft top keeps the car lighter and more compact than the folding hardtops BMW used in earlier generations. BMW says it is reinforced to improve insulation and reduce outside noise when raised.
Compared with the BMW 4 Series Gran Coupe, the Convertible gives up rear doors and much of the cargo flexibility in return for a more special driving experience. Buyers who need regular rear-seat access or a liftback cargo area should choose the Gran Coupe instead.

These are current US starting MSRPs for the 2027 model year. Prices exclude destination charges, taxes, title, registration, options, accessories, and dealer fees.

| Trim | Starting MSRP | Drivetrain | Power | Best For |
| 430i Convertible | $61,300 | RWD | 255 hp | Best entry price and fuel economy |
| 430i xDrive Convertible | $63,300 | AWD | 255 hp | All-weather open-top driving |
| M440i Convertible | $75,200 | RWD | 386 hp | Six-cylinder performance and rear-drive balance |
| M440i xDrive Convertible | $77,200 | AWD | 386 hp | Fastest acceleration and four-season traction |
Which Trim Is Best?
- Best value: 430i Convertible
- Best all-round choice: 430i xDrive Convertible
- Best for efficiency: 430i Convertible
- Best for traditional BMW handling: M440i Convertible
- Best for maximum acceleration: M440i xDrive Convertible
- Best for rain or snow: 430i xDrive or M440i xDrive Convertible
The 430i is quick enough for daily driving. It costs much less than the M440i and is the better fit for buyers who want a refined luxury convertible rather than a performance car.
The M440i has the engine that makes this BMW feel genuinely special. Its inline-six is smoother, stronger, and more enjoyable, but it also brings a major increase in purchase price, insurance, tire costs, brake costs, and fuel spending.
Engine, Powertrain, and Performance
The 430i Convertible uses a turbocharged 2.0-liter inline-four with mild-hybrid assistance. It produces 255 horsepower and 295 lb-ft of torque.
The M440i Convertible uses a turbocharged 3.0-liter inline-six with mild-hybrid assistance. It produces 386 horsepower and 398 lb-ft of torque.
All trims use an eight-speed automatic transmission. The 430i and M440i are rear-wheel drive, while xDrive all-wheel drive is available on both.
0–60 MPH Performance
| Trim | BMW-Estimated 0–60 mph Time |
| 430i Convertible | 6.0 seconds |
| 430i xDrive Convertible | 5.9 seconds |
| M440i Convertible | 5.0 seconds |
| M440i xDrive Convertible | 4.6 seconds |
BMW labels these as preliminary figures. Actual acceleration can vary with vehicle specification, road surface, weather, tires, and driving conditions.
The 430i feels responsive and relaxed for normal driving. The M440i is much quicker, especially when passing or accelerating onto a highway. It is not an M4, but it has enough pace to satisfy most performance-focused buyers.
Driving Experience
The 4 Series Convertible is more about enjoyable road trips and relaxed weekend drives than the sharpest possible handling. Still, it feels more connected than many luxury convertibles thanks to its rear-wheel-drive platform and well-controlled chassis.
The 430i is the better daily driver. It has enough power, decent fuel economy, and a more manageable price. The 430i xDrive makes sense if you expect regular rain, snow, or cold-weather driving.
The M440i gives the Convertible a much more serious character. The rear-wheel-drive version is the purer enthusiast option, while the M440i xDrive delivers quicker launches and more confidence in poor weather.
Larger wheels and performance tires improve appearance and cornering response, but they can make rough roads more noticeable. They also cost more to replace.
Fuel Economy
BMW currently lists the following US city/highway fuel-economy figures for the 2027 4 Series Convertible range:
| Model | City / Highway / Combined mpg |
| 430i Convertible | 27 / 35 / 30 mpg |
| 430i xDrive Convertible | 24 / 33 / 27 mpg |
| M440i Convertible | 27 / 33 / 29 mpg |
| M440i xDrive Convertible | 26 / 32 / 28 mpg |
The 430i is the best pick for buyers concerned about fuel costs. The M440i remains reasonably efficient for a 386-hp luxury convertible, but its premium-fuel requirement and higher price make it costlier to run.
EPA ratings, wheel choices, and real-world fuel use can vary. Confirm the exact window-sticker figure for the car you are considering.
Interior, Comfort, and Technology
The 4 Series Convertible has a low driving position, supportive front seats, and BMW’s curved digital display. It feels premium from the front seats, particularly with upgraded leather, audio, and driver-assistance options.
Standard and available features include:
- BMW Curved Display
- BMW Operating System 8.5 with QuickSelect
- Wireless Apple CarPlay and Android Auto
- Navigation
- BMW Intelligent Personal Assistant
- BMW Digital Key
- My BMW app connectivity
- Remote engine start
- Heated front seats
- Available ventilated front seats
- Available heated steering wheel
- Available head-up display
- Available Harman Kardon audio
- Available ambient lighting
- Available Parking Assistant Plus
- Available Driving Assistant Professional
The front seats are comfortable for commuting and road trips. The rear seats are useful for children, smaller adults, or short journeys, but they are not a strong point.
Dimensions, Cargo, and Practicality
| Dimension | Measurement |
| Length | 187.9–188.0 in. |
| Width | 72.9 in. |
| Height | 54.6–54.9 in. |
| Wheelbase | 112.2 in. |
| Cargo space, roof raised | 13.6 cu. ft. |
| Cargo space, roof lowered | 10.6 cu. ft. |
| Seating capacity | 4 passengers |
| Fuel capacity | 15.6 gallons |
The Convertible can handle a weekend for two, groceries, and smaller everyday items. But the roof mechanism takes up trunk room when lowered, so packing requires more planning than in the Coupe.
It is best treated as a two-person car with occasional rear-seat use. The BMW 4 Series Gran Coupe is much better if you regularly carry passengers, luggage, sports gear, or child seats.
Soft Top and Exterior Design
The 4 Series Convertible has a fabric soft top rather than a folding metal roof. It can be raised or lowered in around 10 seconds at speeds up to 30 mph.
BMW includes a wind deflector to help reduce cabin turbulence with the roof down. The fabric roof is designed to reduce road noise and improve insulation when closed, though it will not be as quiet as the Coupe’s fixed roof.
Exterior highlights include:
- Power-operated fabric soft top
- Convertible wind deflector
- LED headlights
- Available adaptive lighting
- Available laser rear lights
- Large BMW kidney grille
- Available M Sport styling
- Available Shadowline exterior trim
- Available 18- and 19-inch wheels
- More aggressive M-specific styling on M440i models
Safety Features and Ratings
Standard and available driver-assistance equipment includes:
- Forward collision warning
- Automatic emergency braking
- Lane-departure warning
- Blind-spot monitoring
- Rearview camera
- Front and rear parking sensors
- Automatic high beams
- Available Parking Assistant Plus
- Available 3D surround-view camera system
- Available Driving Assistant Professional
- Available adaptive cruise control and lane-centering support
Driving Assistant Professional can help manage distance and lane position in certain situations. It is a Level 2 assistance system, not a self-driving system. The driver must remain attentive and ready to take control.
The current 4 Series Convertible does not have a separate current IIHS or NHTSA crash-test rating listed at the time of writing. Check the latest IIHS ratings and NHTSA safety database before purchase.
Reliability, Warranty, and Ownership
The 4 Series Convertible uses established BMW turbocharged engines, but it remains a complex luxury car with advanced electronics, a power soft-top mechanism, and costly parts.
The 430i is the lower-risk ownership choice. It costs less to buy, uses less fuel, and should have lower expected tire, brake, and insurance expenses than the M440i.
The Convertible’s roof deserves extra attention on used examples. Check for water leaks, unusual wind noise, slow roof operation, damaged seals, blocked drains, and any signs of water in the trunk or cabin.
BMW’s current US coverage includes:
| Coverage | Length |
| New vehicle limited warranty | 4 years / 50,000 miles |
| Scheduled maintenance | 3 years / 36,000 miles |
| Roadside assistance | 4 years / unlimited miles |
| Rust perforation warranty | 12 years / unlimited miles |
For a used BMW 4 Series Convertible, inspect roof operation, service history, tires, brakes, electronics, accident history, and open recalls. A VIN check can help confirm the car’s identity and original equipment.

Competitors
The BMW 4 Series Convertible competes with:
- Mercedes-Benz CLE Cabriolet
- Ford Mustang Convertible
- BMW M4 Convertible
- Lexus LC 500 Convertible
The Mercedes-Benz CLE Cabriolet is the closest luxury alternative for buyers focused on comfort, design, and four-seat open-air driving. The Ford Mustang Convertible offers more accessible performance, though it does not match the BMW’s cabin quality or European driving feel.
The 4 Series Convertible is the stronger choice for buyers who want a premium interior, modern technology, available all-wheel drive, and a choice between an efficient four-cylinder and a powerful inline-six.

The 430i Convertible is the sensible option. It is efficient for its class, quick enough for daily use, and meaningfully cheaper than the M440i. The M440i Convertible is the better choice for drivers who want the smooth, powerful inline-six engine that gives the car real performance character.
It is expensive, not especially practical, and costly to own long term. But for buyers who value open-air driving, premium technology, and a proper rear-wheel-drive BMW feel, the 4 Series Convertible remains one of the best luxury convertibles available.
