BMW 4 Series Gran Coupe trim comparison
2025 BMW 4 Series Gran Coupe 430i xDrive vs M440i xDrive
The 4 Series Gran Coupe 430i xDrive starts at $51,650 while the M440i xDrive is $65,200. That $13,550 gap buys 6 meaningful differences.
This trim jump changes the engine from 2.0L I4 mild-hybrid Turbo to 3.0L I6 mild-hybrid Turbo. Everything else is secondary to whether that powertrain difference matters for how you drive.
Start with the 430i xDrive if the 2.0L I4 mild-hybrid Turbo already feels sufficient for the way you drive. Step up to the M440i xDrive only when the 3.0L I6 mild-hybrid Turbo powertrain is the reason you are moving higher in the lineup.
Think about this as a monthly tradeoff, not just a sticker gap. The M440i xDrive adds about $238/month on a typical 60-month loan, or around $14,280 more overall with interest. The payment only makes sense if that different powertrain matters to the way you actually drive, tow, or live with the vehicle.
