BMW 4 Series trim comparison
2025 BMW 4 Series M4 vs M4 CS
The 4 Series M4 starts at $79,700 while the M4 CS is $123,500. That $43,800 gap buys 5 meaningful differences.
The M4 CS adds AWD instead of RWD. If you deal with winter roads or need traction off-pavement, that could be worth $43,800 by itself. If not, the M4 saves you the money.
The M4 is the cleaner fit if RWD already covers the job. The M4 CS 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 M4 to the M4 CS is about $772/month on a 60-month loan at 6.5% APR with 10% down. That works out to roughly $46,320 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.
