Mercedes-Benz S-Class Mileage in India
Mileage is an important consideration for luxury car buyers, particularly when evaluating long-distance travel and daily running costs.
The 2026 Mercedes-Benz S-Class S 450e has a published WLTP fuel-efficiency figure of approximately 32.3 km/l. This figure relates to the plug-in hybrid's certified test cycle and should not be interpreted as guaranteed real-world petrol mileage.
The vehicle also offers a claimed electric-only driving range of up to 115 km under specified test conditions. Regular charging can help drivers complete suitable daily journeys using electric power, potentially reducing petrol consumption.
Actual fuel efficiency depends on several factors:
-
How frequently the battery is charged
-
The proportion of driving completed in electric mode
-
Traffic and road conditions
-
Driving style and vehicle load
-
Air-conditioning use and outside temperature
For buyers who can charge the vehicle regularly, the plug-in hybrid system may offer meaningful benefits during shorter daily journeys. For long highway journeys without frequent charging, petrol consumption will depend more heavily on driving conditions and the hybrid system's operation.

Charging times depend on the charger, battery temperature, charging conditions, and vehicle configuration. The electric range achieved in everyday driving may also differ from the certified figure.
For buyers with access to home or workplace charging, the plug-in hybrid system can make the S-Class more versatile for routine commuting while retaining long-distance touring capability.
