The S 450e will be Mercedes-Benz India's first plug-in hybrid model outside its AMG lineup, featuring a 22kWh battery with 100km of electric-only range.
It is expected to be locally assembled at the Chakan plant and launched alongside the petrol and diesel variants of the refreshed S-Class.
The facelifted Mercedes-Benz S-Class has already made its global debut, and India is firmly on the roadmap. The standard model is expected to be introduced in the country towards the end of 2026 or early 2027. What makes this launch particularly noteworthy, however, is the addition that will accompany it.
Alongside the petrol S 450 and diesel S 350d, Mercedes-Benz India will launch its first-ever plug-in hybrid model outside of its AMG range, in the form of the S 450e with EQ Hybrid Technology.
S 450e Powertrain Explained: More Output, Less Weight Efficiency
At first glance, the S 450e and the S 450 petrol look like close cousins, but under the skin, they are quite different propositions. Both models share the same 2,999cc 'M256 Evo' turbocharged petrol engine, updated to meet Euro 7 emissions norms.
The S 450 relies on a 48V mild-hybrid system for a short burst of supplementary power, but the S 450e goes considerably further. It incorporates a plug-in hybrid system with a large 22kWh battery that continuously alternates between electric and combustion power during driving.
On its own, the engine produces 326hp and 540Nm, but paired with a 120kW electric motor, the S 450e delivers total system outputs of 435hp and 680Nm. The sprint from 0 to 100kph takes 5.7 seconds, which is slower than the pure petrol S 450's 4.9 seconds.
Unlike the S 450, which uses 4Matic all-wheel drive, the S 450e is rear-wheel drive only and, owing to the battery pack, weighs a considerable 2,465kg.
100km Electric Range Makes It a Convincing Bridge to Full EV Ownership
The real selling point of the S 450e is not the headline power figure, but the practicality of its electric capability. The 22kWh battery offers up to 100km of electric-only range and can be topped up via a charging plug, meaning owners using the car primarily within the city could potentially use it as a full EV, with the petrol engine serving as a safety net for longer journeys.
For more traditional limousine buyers who were previously on the fence about transitioning to an electric vehicle, the S 450e could serve as the ideal bridge product, letting them experience silent, zero-emissions motoring and home charging without the concern of range anxiety.
There is also a strategic angle for Mercedes-Benz India. The S 450e addresses customers who wanted electric mobility but felt the EQS did not feel as luxurious as an S-Class. Word is that the EQS limousine facelift will not be launched in India.
Local Assembly at Chakan Likely to Keep Pricing in Check
Pricing will be a key factor in how well the S 450e is received, and Mercedes-Benz appears to have a plan. The brand currently assembles the long-wheelbase S-Class, the extra-long-wheelbase Maybach S-Class, and the EQS electric sedan at its plant in Chakan, Maharashtra. Local assembly of the S 450e would be a logical step to ensure its price does not disrupt the existing model hierarchy too severely.
The S 450e is expected to launch alongside the petrol and diesel variants and be positioned slightly above them, yet below the Maybach S-Class. It would not be India's first taste of a luxury PHEV either.
Previous examples include the Volvo XC90 T8, Porsche Cayenne S e-hybrid, and the previous-generation BMW 740Le. With hybrid technology finally gaining meaningful traction in India, the timing for Mercedes to bring in a plug-in flagship feels just about right.
