BMW 3 Series or BMW 4 Series: which fits Norwood buyers?
Choose the BMW 3 Series if you want a four-door sedan, and the 4 Series if you want a coupe, convertible or Gran Coupe body style. The gap in starting MSRP is the premium for that styling. BMW of Norwood carries both, and you can book a test drive online for any new vehicle in inventory.
Keep reading below, then schedule a test drive in Norwood. Bringing your own numbers to the lot settles this faster than any spec sheet.
Norwood four-door buyers fit the 3 Series; coupe buyers fit the 4 Series
At BMW of Norwood, we sell both the 3 Series and the 4 Series. The 3 Series is the four-door sedan. The 4 Series comes as a coupe, a convertible or a Gran Coupe with a liftback, so the choice starts with the body you want to live with every day.
The 3 Series starts at $48,000 for the 330i Sedan, the lowest-priced 3 Series trim. The 4 Series starts at $51,200 for the 430i Gran Coupe, the lowest-priced 4 Series trim. If you want a sedan, the 3 Series is the direct path. If you want a coupe or a convertible, the 4 Series is the path, and it is the body style you pay for.
How much more does a 2026 BMW 4 Series cost than a 3 Series?
The 430i Gran Coupe starts at $51,200, $3,200 above the 330i Sedan’s $48,000. Comparing the xDrive versions, the 430i xDrive Gran Coupe starts at $53,200 against the 330i xDrive Sedan’s $50,000, a $3,200 gap. That gap is the cost of the 4 Series body style, with the same 255 hp engine underneath.
The gap grows as you move up the range. The 430i Coupe starts at $53,300 and the 430i Convertible at $61,300. A buyer who wants a coupe or convertible pays for that body, and the M440i Convertible starts at $75,200.
How much power do the BMW 330i, 430i, M340i and M440i make?
The 330i and 430i make the same output. Both the 330i xDrive Sedan and the 430i xDrive Gran Coupe list 255 hp and 295 lb-ft of torque from a 2.0-liter engine. The power choice is between the two performance trims.
The M340i xDrive Sedan and the M440i xDrive Coupe each list 386 hp and 398 lb-ft of torque from a 3.0-liter six-cylinder. If you want more performance, that is the step up, and the M340i and M440i share the same powertrain figures.
Can you get xDrive all-wheel drive on both the BMW 3 Series and 4 Series?
Yes. BMW of Norwood carries xDrive all-wheel drive on both models. The 330i xDrive Sedan is rated 26 city, 34 highway and 29 combined by the EPA. The 430i xDrive Gran Coupe is rated 25 city, 34 highway and 29 combined.
The 430i xDrive Coupe is the most efficient of the xDrive 4 Series, at 27 city, 34 highway and 30 combined. If you want all-wheel drive and the coupe body, that is the trim to compare against the 330i xDrive.
What changes between the BMW 3 Series and 4 Series, trim by trim?
The 3 Series lineup runs from the 330i Sedan at $48,000 to the M340i xDrive Sedan at $64,300. The 4 Series lineup runs from the 430i Gran Coupe at $51,200 to the M440i xDrive Convertible at $77,200. Each step up adds body style or power.
Trim by trim, the 330i Sedan and 430i Gran Coupe share 255 hp and 295 lb-ft. The 330i xDrive Sedan and 430i xDrive Gran Coupe do the same. Where they differ is body and price, so the decision comes down to the body you want.
When is the BMW 3 Series or 4 Series the wrong fit for you?
If you need five seats in a coupe body, the 4 Series is not the fit. The 430i Coupe, 430i xDrive Coupe, 430i Convertible and M440i Coupe each seat four. If five seats matter, the 430i Gran Coupe and M440i Gran Coupe seat five, and so does every 3 Series sedan.
If you need a sedan, the 3 Series is the fit. Every 3 Series trim seats five. Choosing a 4 Series means choosing a body style with fewer seats in the coupe and convertible versions.

I expected pressure to purchase services that I didn’t want. They appropriately pointed out and showed me pictures of problems with the car and gave estimates to fix them but did not pressure me to purchase these services.
