Core summary
The M440i combines a turbocharged straight-six with a more everyday brief than the M4. Choose the G22 Coupe, G23 Convertible or G26 Gran Coupe by passenger and luggage needs before comparing equipment.
The current-generation family covered here includes G22 Coupe, G23 Convertible and G26 Gran Coupe. They should not be represented by one door count, seat count or luggage description. The Gran Coupe’s dated US introduction supplies the numerical reference below; it does not define every M440i worldwide.
History & generations
The G26 Gran Coupe arrived after the two-door version and brought a five-door alternative to the 4 Series family. BMW’s 2021 announcement described the second-generation Gran Coupe for the 2022 US model year. Later drivetrain and cabin updates should be identified separately when evaluating a newer car.
Body, platform & design
The Coupe prioritises a two-door outline; the Convertible changes the experience through an opening roof; the Gran Coupe adds rear doors and a large hatch. The latter is not just a Coupe with a different trim package. Cargo access is a structural difference and can be the deciding reason to choose it.

Engine & drivetrain
The cited US M440i xDrive Gran Coupe uses a 3.0-litre turbocharged inline-six with 48-volt mild-hybrid assistance, rated at 382 hp and 369 lb-ft. An eight-speed automatic and xDrive complete that specification. Do not replace those US figures with European PS ratings without identifying the change of reference.
Trim differences
M440i is distinct from an M Sport-equipped 430i and from an M4. These names describe different levels of mechanical specification, not just badges. After establishing the derivative, compare the body and driven wheels offered in the relevant market; the Gran Coupe reference is not proof that every Coupe listing is xDrive.
Interior & seating
BMW’s Gran Coupe launch describes five seats and a 40:20:40 split rear backrest. Its practicality differs from the two-door bodies even though the front-cabin identity is related. A buyer carrying adults often should weigh rear-door access against the appeal of the Coupe’s shape before comparing upholstery.
Efficiency & range
Mild-hybrid assistance is not externally charged electric commuting. For running costs, compare the selected M440i body with a similarly used 430i rather than averaging different versions. The added performance should be something the buyer values, because the engine badge alone does not establish lower ownership cost.
Safety & equipment
Check the actual assistance package and tyre specification on the selected body. Convertible, Coupe and Gran Coupe listings should not be assumed to share every standard feature. Driver aids remain separate from the decision to buy a six-cylinder derivative; performance does not establish the assistance inventory.
Strengths
The range offers a way to retain a six-cylinder drivetrain while changing the body to suit the job. The Gran Coupe makes that particularly relevant to a one-car household. The value is not that one version is universally superior, but that the owner need not choose a two-door body solely to obtain the M440i powertrain.
The M440i is a body-style decision wrapped around a straight-six. Coupe, Convertible and Gran Coupe can suit very different lives despite sharing the same engine badge.
Considerations
An advertisement that says only M440i leaves too much unresolved. Establish body code, model year and market before comparing output or equipment. For a Convertible, roof operation is an additional inspection item that is irrelevant to a Gran Coupe; generic model checklists can miss that distinction.
Recommended use
Choose the Gran Coupe for frequent rear-passenger and hatch use, the Coupe for a two-door touring brief, and the Convertible when open-air driving is central. This is an editorial use-case distinction, not a measured claim about handling differences. The normal passenger routine should lead the choice.
Rivals & related
The Audi S5 Sportback is a natural Gran Coupe reference, while two-door alternatives should be compared with the Coupe or Convertible. A BMW M340i Touring may be more relevant than either if cargo access dominates. The M4 belongs in the discussion only when its more specialised performance brief is actually wanted.
FAQ
Q: Is every M440i a two-door car?
A: No. The G26 Gran Coupe has rear doors and a hatch.
Q: Is M Sport the same as M440i?
A: No. It does not establish the six-cylinder derivative.
Q: Do the US figures apply to every version?
A: No. They describe the cited launch specification.
