BMW 4 Series trim comparison
2024 BMW 4 Series 430i xDrive vs M4
The 4 Series 430i xDrive starts at $60,100 while the M4 is $78,100. That $18,000 gap buys 7 meaningful differences.
This is a powertrain and drivetrain change. The M4 gets the 3.0L I6 Turbo and RWD, so the $18,000 is buying a different driving experience, not just nicer trim.
Choose the 430i xDrive if the 2.0L I4 Turbo with AWD already covers the way you drive. Move to the M4 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.
The cleanest way to feel this upgrade is through the payment: about $317/month more over 60 months, or roughly $19,020 extra all-in once interest is included. The payment only makes sense if that different powertrain matters to the way you actually drive, tow, or live with the vehicle.
Lock one trim, change the other side, and move through exact pair pages without resetting back to the full lineup every time.

Is the 4 Series M4 Worth $18,000 More?
The 4 Series M4 costs $18,000 more than the 430i xDrive. Whether that is worth it depends on how much you value the 3.0L I6 Turbo engine (+218 hp) and RWD. Power and comfort matter differently to different buyers. Weigh them against your priorities.
The Differences You'll Notice Most
Engine changes between these trims: the 430i xDrive has the 2.0L I4 Turbo, the M4 the 3.0L I6 Turbo. That means 218 more horsepower and 111 more lb-ft of torque. That extra power shows up most clearly once you are out of town and asking more of the drivetrain. The cost of that extra capability is roughly 8 fewer combined MPG. The M4 drops to RWD from the 430i xDrive's AWD. Less traction capability, but potentially better fuel economy.
Fuel Economy Comparison
The 4 Series 430i xDrive gets 8 more combined MPG. At $3.50/gallon and 12,000 miles/year, that saves roughly $655 per year or $3,275 over five years of ownership.
Bottom Line
$18,000 more for the 4 Series M4 gets you 6 real differences. At $317/month more, the question is whether those specific changes are things you will use regularly.
