Mercedes-Benz E-Class trim comparison
2026 Mercedes-Benz E-Class E 350 vs E 450 4MATIC
The E-Class E 350 starts at $63,900 while the E 450 4MATIC is $72,300. That $8,400 gap buys 7 meaningful differences.
This is a powertrain and drivetrain change. The E 450 4MATIC gets the 3.0L I6 mild-hybrid Turbo and AWD, so the $8,400 is buying a different driving experience, not just nicer trim.
This is a real hardware fork, not just a trim-label shuffle. The E 350 is enough if the 2.0L I4 mild-hybrid Turbo with RWD already fits your routine; the E 450 4MATIC only earns the jump when the 3.0L I6 mild-hybrid Turbo and AWD setup is the point of the upgrade.
The cleanest way to feel this upgrade is through the payment: about $148/month more over 60 months, or roughly $8,880 extra all-in once interest is included. If that different powertrain is not part of your real use case, the cheaper trim keeps more money in your pocket without changing the core experience you need.
