Mercedes S-Class Plug-in Hybrid (S 450e) in India: Is the PHEV the Smart Choice in 2026?

In India, the plug-in hybrid isn’t one S-Class option among several. It is the S-Class. Autocar India currently lists only the S 450e, at Rs 2.20 crore to Rs 2.38 crore ex-showroom, so the real question is whether this car makes sense for you at all, or whether an EQS, a BMW 7 Series or a pre-owned S-Class is the smarter buy. Our view: the S 450e is a smart choice if the car charges every night and spends most of its life in the city, ideally with a chauffeur. If it will mostly cover long highway runs, or you have nowhere to plug in, you are paying a premium to carry a battery around.

Mercedes S 450e at a glance

Sources: Mercedes-Benz India’s S-Class page (battery, charging, boot), Autocar India’s launch report of 15 June 2026 and its April 2026 preview (outputs, price, performance).

One range caveat up front. Mercedes India quoted up to 115km at launch, but Mercedes-Benz’s global press material for the new S-Class talks about an electric range of around 100km for its plug-in hybrids, and evo India’s first drive cited a claimed 95 to 117km. Claimed figures are made on a test cycle, so plan your routine around something closer to the lower number until Indian owners report real-world results.

S 450e price in India and how it compares

The S 450e launched on 15 June 2026. Its starting price is Rs 35 lakh higher than the previous S-Class, which began at Rs 1.85 crore, according to Autocar India.

Prices from Autocar India’s Mercedes-Benz and BMW listings (updated between 16 September and 15 October 2026).

Two things explain why the plug-in costs more than you might expect.

It is imported. Reports at launch said the S 450e comes in as a fully built import, and that Mercedes was considering assembling it at its Chakan plant. Autocar India’s April preview also called local assembly likely. Neither is a confirmed plan, but if it happens, the price could come down, as it did for other locally assembled luxury cars.

It gets no tax break. In India a plug-in hybrid is taxed like a conventional car. JSW MG Motor’s Parth Jindal said in August 2026 that PHEVs attract 40 percent GST, the same as diesel cars, while electric cars pay 5 percent, as reported by Autocar Professional. That gap is a big part of why an EQS 580 costs Rs 65 lakh less than an S 450e.

What the plug-in actually gets you in Indian traffic

The S 450e’s strongest case is a very Indian one: a chauffeur-driven limousine doing short, slow city runs.

In stop-start traffic, an engine is at its least efficient and a motor at its best. With up to 115km of claimed electric range, a car that does a typical office loop and a couple of meetings can go for days on electricity if it is charged overnight. evo India’s first drive found the car almost silent in electric mode, with the engine joining in smoothly, and the instant electric torque filling the gap while the turbos spool up.

What it costs to run on electricity. The battery holds about 22kWh usable, and some energy is always lost while charging. At an illustrative tariff of Rs 8 per unit, a full charge costs roughly Rs 200 at home. Your own number depends on your state, discom and slab, so check your bill. Even at higher tariffs, a full charge costs a fraction of the petrol needed to cover the same distance in a 2.5-tonne limousine.

Charging is easy if you have parking. The 11kW AC charging means an empty-to-full charge in about two and a quarter hours on a wallbox, and a DC fast charger takes it from 10 to 80 percent in 20 minutes. Mercedes India’s page lists an 11kW charging cable among the equipment, but it does not say a wallbox is included, so ask the dealer in writing. For apartment owners, our guide to the home EV charger and society NOC covers the load and permission questions.

What you give up

• Boot space. Mercedes India lists the S 450e’s boot at 345 litres, and evo India called it abysmal. That matters for an airport car carrying two large suitcases plus cabin bags. Take your actual luggage to the showroom and try it.
• Weight. Autocar India puts the S 450e at 2,465kg. The motor hides it in a straight line, but you pay for it in tyres and brakes over time.
• All-wheel drive and a diesel. The S 450e is rear-wheel drive. Autocar India reports that a 48V mild-hybrid S 450 4MATIC petrol is expected in India later, and evo India’s review suggested Mercedes may never bring a diesel S-Class back.
• Simplicity. A plug-in hybrid has both an engine and a high-voltage system. Ask what the warranty on the high-voltage battery covers, for how long, and whether it transfers if you sell. Mercedes India’s model page does not state it.

When the S 450e is the smart choice, and when it isn’t

Buy the S 450e if:

• You have a dedicated parking spot where a wallbox can go, and someone will plug the car in every night.
• Most of your running is in the city, with a chauffeur, and daily distances fit within the electric range.
• You want an S-Class specifically, rear seat and all, and are not ready for a fully electric car on long trips.

Look elsewhere if:

• You mostly drive between cities. On a long highway run the battery is soon spent, and you are carrying its weight on petrol for the rest of the trip.
• You cannot charge at home or work. An unplugged plug-in hybrid is a heavy petrol car with a small boot.
• You are happy to go electric. The EQS 580 costs Rs 65 lakh less and carries an ARAI-certified range of 857km, according to Autocar India. The trade-off is that the EQS was never quite as special inside as an S-Class, which Autocar India itself noted when explaining why Mercedes is bringing the S 450e.
• You want the driver’s car. The BMW 7 Series is Rs 25 lakh cheaper and keeps a simpler mild-hybrid petrol layout.

Should you buy now, wait, or buy pre-owned?

Three things are worth weighing before you sign.

1. Local assembly. If Mercedes does assemble the S 450e in India, new prices could fall. That matters most if you plan to sell within two or three years.
2. The S 450 4MATIC petrol. If you want an S-Class and do not want a plug-in, Autocar India expects a mild-hybrid petrol to follow.
3. A pre-owned S-Class. The pre-facelift S-Class came with conventional petrol and diesel engines and cost a lot less new. It is the obvious alternative if you cannot charge at home. Have the air suspension checked separately, as we explain in our air suspension problems guide, and compare pre-owned luxury sedans and demo cars before deciding.

Verdict

The S 450e is the most sensible way Mercedes has found to make its limousine cleaner and quieter without asking S-Class buyers to change how they live. In Indian city traffic, with a chauffeur and a wallbox, it will spend most of its days running on electricity, and it does it very well.

It is not automatically the smart choice. A 40 percent GST rate, an imported price and a 345-litre boot make it a car that only pays off if you plug it in. If you will, buy it. If you won’t, the EQS, the 7 Series or a good pre-owned S-Class make more sense.

FAQ

What is the price of the Mercedes S 450e in India?

The Mercedes-Benz S 450e costs Rs 2.20 crore ex-showroom in Launch Edition Exclusive Line trim and Rs 2.38 crore in Manufaktur Edition AMG Line trim, as of October 2026. It launched on 15 June 2026, and its starting price is Rs 35 lakh higher than the previous S-Class.

What is the electric range of the S-Class plug-in hybrid?

Mercedes-Benz India claimed up to 115km of electric-only range for the S 450e at launch, from a 21.96kWh usable battery. Mercedes-Benz’s global press material describes the plug-in hybrid’s electric range as around 100km. Real-world range will be lower than the claim, especially with the air conditioning running hard.

How long does the S 450e take to charge?

On an 11kW AC wallbox, Mercedes-Benz India quotes 2.25 hours for a full 0 to 100 percent charge. On a DC fast charger of up to 60kW, a 10 to 80 percent charge takes about 20 minutes.

Is the S-Class plug-in hybrid better than the EQS?

It depends on how you drive. The S 450e suits owners who want the S-Class cabin and a petrol engine for long trips, and who charge daily for city use. The EQS 580 is Rs 65 lakh cheaper, pays 5 percent GST instead of 40 percent, and has an ARAI-certified range of 857km, so it makes more sense if you are ready for a fully electric car.

Does the Mercedes S 450e get any tax benefit in India?

No. Plug-in hybrids attract 40 percent GST in India, the same as diesel cars, while electric cars pay 5 percent. That is one reason the S 450e costs more than the electric EQS 580.

What are the downsides of the S 450e?

The main ones are a small 345-litre boot, a kerb weight of around 2,465kg, rear-wheel drive only, and no tax advantage over a conventional car. It also needs regular charging to deliver its benefits. Without it, the S 450e behaves like a heavy petrol car.
