The Mercedes-Benz S-Class specifications describe a single plug-in hybrid powertrain shared across both trims. There is no separate petrol or diesel to weigh. The spec sheet focuses instead on the hybrid system, the cabin and the ride. There is one battery size and one power output across the range. The numbers describe a single well-equipped car in two looks.

The S 450e pairs a 3.0 litre inline-six turbo petrol with an electric motor and a 22 kWh battery. Combined output is 435 PS and 680 Nm. A nine-speed automatic sends power to the rear wheels. The engine displaces 2999 cc as a straight six.

The ARAI figure is a high 32.3 kmpl, but that leans heavily on the electric range. Drive with a flat battery and real consumption climbs well above that number. Electric-only range is quoted at up to 115 km. Regular charging is the key to low running costs.

It runs 5304 mm long on a 3216 mm wheelbase, among the largest sedans here. Width is 1921 mm and height 1503 mm. The battery trims the boot to 345 litres, and the tank holds 67 litres. Seating is for five across two rows. The long wheelbase frees up rear legroom. The car's kerb weight is high for a sedan.

Equipment is near the ceiling of what Mercedes-Benz offers, on both trims. The AMG Line changes the look rather than the mechanicals. Both carry the same 435 PS output and 115 km electric range. See local S-Class pricing to plan the total spend at this level.

Mercedes-Benz S-Class power and torque explained

In India the S-Class comes with just one powertrain, the S 450e. It pairs a 3.0 litre inline six turbo petrol engine with an electric motor and a 22 kWh battery, and the two work together for 435 PS and 680 Nm.

This is a calm, effortless powertrain, not one that wants revving. On paper it manages 32.3 kmpl, strong for a car this size, so it is worth checking how the fuel figures stack up. The electric motor gives instant, silent shove from a standstill, and a full charge covers up to 115 km before the petrol engine wakes up.

How to read this chart. Torque is the push you feel when you accelerate, and it peaks low on the rev range. Power is how hard the engine keeps pulling as it revs higher, and it peaks further up. The two dots mark those peaks. The shaded strip between them is the flexibility band: a wider band pulls easily across more revs and feels relaxed in traffic, while a narrower band asks you to rev the engine more to get its best.

Peak figures come from the 3.0L Inline-6 Turbo Petrol Plug-in Hybrid spec sheet. The line between the two peaks is not a measured dyno curve.

The S 450e blends that 3.0 litre inline six with an electric motor, and the way it puts down power suits this big sedan. Its full 680 Nm of torque arrives at just 2200 rpm, so the car surges forward the moment traffic clears, with the motor filling any gap below that. Peak power of 435 PS lands at just 4250 rpm, only 2050 rpm above the torque peak, so all the muscle sits low and in the middle of the rev range. You never need to work the engine hard. That makes it relaxed in city traffic and quietly rapid for highway overtakes, whether the car is running empty or fully loaded. Since both trims share this same setup, you can compare the two trims on kit and price rather than on how they drive.
