Mercedes-Benz S-Class trim comparison
2026 Mercedes-Benz S-Class S 500 4MATIC vs S 580 4MATIC
The S-Class S 500 4MATIC starts at $119,500 while the S 580 4MATIC is $130,700. That $11,200 gap buys 7 meaningful differences.
This trim jump changes the engine from 3.0L I6 mild-hybrid to 4.0L V8 mild-hybrid Turbo. Everything else is secondary to whether that powertrain difference matters for how you drive.
Start with the S 500 4MATIC if the 3.0L I6 mild-hybrid already feels sufficient for the way you drive. Step up to the S 580 4MATIC only when the 4.0L V8 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 S 580 4MATIC adds about $198/month on a typical 60-month loan, or around $11,880 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.
