Year over year

What changed

  • The S 400 HYBRID became the first hybrid configuration in the U.S. S-Class roster.
  • Six configurations now spanned hybrid, naturally aspirated V8, and twin-turbo V12 applications.

Worth knowing

Notable

  • The hybrid requires its own high-voltage and service-parts applicability rather than sharing the S 550 page.

Living with it

Reliability & ownership notes

  • Inspect Airmatic or Active Body Control operation, electronics, cooling-system condition, and documented service history on the individual car; a generation-level reputation is not evidence that every example has a fault.
  • Match filters, fluids, ignition or diesel-service parts, brakes, and transmission service items to the exact engine, drivetrain, build date, and VIN before ordering.

Maintenance & service parts

Keep your 2010 S-Class on the road

Start with the service interval, then match the engine or exact version you own. Order links appear only when a catalog-backed part number is available, and every listing still needs a fitment check.
