BMW 4 Series Convertible M440i xDrive Convertible

The M440i xDrive Convertible adds 285 kW six-cylinder pace and AWD to the G23 soft-top experience.

BMW M440i xDrive Convertible combines two specialist attractions: open-roof touring and a 285 kW, 500 Nm six-cylinder petrol powertrain. The eight-speed automatic and xDrive help make that output usable across changing road conditions. It is a genuine mechanical step over 420i Convertible M Sport, while remaining separate from the full-M M4 Competition Convertible AWD. Buyers need to value both the engine and roof strongly enough to accept their combined cost and care demands. Performance deserves restraint. xDrive improves propulsion, not wet braking, tyre grip or visibility. Learn drive, gearbox and stability settings during handover and keep reduced assistance away from public roads. Price insurance, security, tyres, brakes and fuel before selecting expensive options. The engine makes passing effortless but cannot shorten a dangerous sight line or erase fatigue. The fabric roof creates another maintenance system. Operate it repeatedly, confirm approved conditions and inspect fabric, seals and drains at collection. Secure covered parking reduces contamination and vandalism risk. Roof-down stops require belongings to be removed from sight. Owners near the coast or under trees need especially prompt cleaning and seal care using approved methods. Practicality changes with roof position. Load a real weekend while the roof is stowed, fit the wind deflector and seat occasional rear passengers. Long doors and performance seats can complicate entry. Roof-up motorway noise and roof-down airflow need separate tests. A buyer who rarely opens the roof may find M440i Coupé more rigid and spacious for the same engine concept. Build-sheet accuracy prevents assumptions. Wheels, seats, brakes, cameras, assistance, paint, roof finish and wind equipment may vary. Large wheels add tyre and pothole exposure and can reduce the grand-touring comfort the Convertible needs. Photograph their condition at handover and retain alignment, roof, service and software records. Use the curved display for normal climate, phone and navigation work as well as performance menus. The car remains road focused. All-wheel drive does not supply clearance, and gravel dust is particularly unwelcome around a fabric roof and mechanism. M440i Convertible is most convincing for a secure-garage owner seeking a powerful open long-distance car without stepping into M4’s full-M chassis. The broad ability is genuine, but only when roof use and six-cylinder performance are both intentional.

Where the BMW 4 Series Convertible Fits Best

A practical view of the buyer and roads this model is best suited to.

Who buys this

M440i Convertible suits an experienced performance buyer with secure covered parking who genuinely wants six-cylinder pace and frequent open-air use. The owner has premium tyre, brake, fuel and insurance budgets and accepts reduced luggage flexibility. Buyers prioritising track focus need M4; those wanting only the roof can save cost with 420i.

City
The automatic and xDrive make the output approachable, but gentle throttle remains essential. Test door clearance, cameras, ramp angles, roof operation and pothole comfort. Open parking requires security discipline and protection from contamination. Fuel use will reflect short trips. Arrange insurance and tracker before delivery, and ensure every regular driver understands the roof and drive controls. Keep belongings hidden whenever the cabin is open.
Highway
Use roof-up motorway travel to assess seal noise, tyre roar and seat comfort; then judge wind and conversation with the roof down on a safe route. Six-cylinder torque makes overtaking easy, but legal speed and weather remain limits. Pack the boot with the roof stowed and carry exact tyre support. xDrive helps propulsion in rain but does not prevent aquaplaning. Passengers need appropriate wind, sun and hearing protection.
Off-Road
M440i xDrive Convertible is a performance road car. Low bodywork, road tyres and the fabric-roof system make rough surfaces unsuitable. Smooth maintained gravel may be crossed very slowly with the roof raised, but stones, dust, corrugations and ruts risk costly damage. AWD cannot create clearance. Remote travel also complicates replacement tyre and roof support. Choose an easier access route or another vehicle for rural properties.

BMW 4 Series Convertible M440i xDrive Convertible — Should You Buy It?

BMW 4 Series Convertible M440i xDrive Convertible: buyer assessment
Hagalu editorial review by Hagalu Editorial Team · 2026-09-28

Prove the roof life at home: covered storage, operating clearance, fabric care and luggage with roof stowed. Then prove the performance budget through exact insurance, tracker, tyres, brakes, fuel and maintenance. Request the build sheet and separate optional wheels, seats, cameras and assistance. Drive roof-up and roof-down, in traffic, over rough tar and on a legal highway segment. Learn modes with safety systems active and document roof, tyres, alignment, software and service from handover. Compare 420i and M4 from needs rather than rank. M440i wins as the road-touring middle ground only when its engine, xDrive and roof are all genuinely used. BMW M440i xDrive Convertible combines two specialist attractions: open-roof touring and a 285 kW, 500 Nm six-cylinder petrol powertrain.

How this score is calculated · Methodology v1.0

A rapid open grand tourer for buyers who will fund, protect and use both its six-cylinder engine and roof.

M440i xDrive Convertible supplies 285 kW, 500 Nm, all-wheel traction and a fabric roof in one broad package. It is materially different from 420i and calmer than M4, but running costs and roof duties remain high. The derivative makes sense when open-air touring and six-cylinder response both matter. If either is ornamental, a fixed-roof M440i or regular 420i Convertible will be more coherent.

What's Good
  • ✓285 kW inline-six
  • ✓500 Nm
  • ✓xDrive traction
  • ✓Open-roof touring
  • ✓Broader remit than M4
Watch Out For
  • ✕High running costs
  • ✕Roof maintenance
  • ✕Reduced luggage space
  • ✕Rear access
  • ✕No gravel ability
