BMW 4 Series trim comparison
2026 BMW 4 Series M440i vs M440i xDrive
The 4 Series M440i starts at $67,100 while the M440i xDrive is $69,100. That $2,000 gap buys 4 meaningful differences.
The M440i xDrive adds AWD instead of RWD. If you deal with winter roads or need traction off-pavement, that could be worth $2,000 by itself. If not, the M440i saves you the money.
The M440i is the cleaner fit if RWD already covers the job. The M440i xDrive only earns the extra money when AWD is the reason you are shopping up.
The cleanest way to feel this upgrade is through the payment: about $35/month more over 60 months, or roughly $2,100 extra all-in once interest is included. The real question is whether AWD changes your day-to-day use enough to justify paying above RWD.
