Gearbox Type: 9G-TRONIC Automatic
Every 2026 S-Class is equipped with the 9G-TRONIC 9-speed automatic transmission. This gearbox is tuned for imperceptible shifts, maximizing fuel efficiency during highway cruises while providing a "kick-down" response that is immediate yet smooth. It is paired with the 4MATIC All-Wheel Drive system as standard in most markets.
