BMW 3 Series trim comparison
2025 BMW 3 Series M340i vs M340i xDrive
The 3 Series M340i starts at $60,200 while the M340i xDrive is $62,200. That $2,000 gap buys 3 meaningful differences.
The M340i 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 M340i saves you the money.
The M340i is the cleaner fit if RWD already covers the job. The M340i xDrive only earns the extra money when AWD is the reason you are shopping up.
If you are budgeting this move monthly, the jump from the M340i to the M340i xDrive is about $35/month on a 60-month loan at 6.5% APR with 10% down. That works out to roughly $2,100 more by the time interest is counted. The real question is whether AWD changes your day-to-day use enough to justify paying above RWD.
Lock one trim, change the other side, and move through exact pair pages without resetting back to the full lineup every time.
