BMW 4 Series trim comparison
2026 BMW 4 Series 430i xDrive vs M4 Competition
The 4 Series 430i xDrive starts at $63,300 while the M4 Competition is $86,400. That $23,100 gap buys 7 meaningful differences.
This is a powertrain and drivetrain change. The M4 Competition gets the 3.0L I6 Turbo and RWD, so the $23,100 is buying a different driving experience, not just nicer trim.
Choose the 430i xDrive if the 2.0L I4 mild-hybrid Turbo with AWD already covers the way you drive. Move to the M4 Competition only when the 3.0L I6 Turbo and RWD combo is the reason you are shopping higher, because that is the real hardware split here.
If you are budgeting this move monthly, the jump from the 430i xDrive to the M4 Competition is about $406/month on a 60-month loan at 6.5% APR with 10% down. That works out to roughly $24,360 more by the time interest is counted. The payment only makes sense if that different powertrain matters to the way you actually drive, tow, or live with the vehicle.
