Mercedes-Benz S 450e: The flagship, in two voices

There’s a moment, when you slip into the back of a new S-Class on a Mumbai monsoon morning, that the rest of the city seems to step backwards. The doors close with that familiar Mercedes-Benz thunk. The cabin settles into its hush. And then — usually — the engine starts, and the car eases into traffic with the low growl that has, for forty years, defined what it means to arrive in an S-Class.

This one moves with a different kind of ease. The new S 450e is Mercedes-Benz India’s first plug-in hybrid in the flagship line. Its 22 kWh lithium-ion battery delivers up to 115 km of pure-electric range (WLTP) — enough to cover most daily commutes across India’s major cities without waking the combustion engine. In everyday driving, the drivetrain seamlessly blends electric and petrol power, with transitions so smooth they go virtually unnoticed from within the cabin. And when the journey stretches beyond the city limits, the petrol engine is ready to take over, offering effortless long-distance capability without the slightest hint of range anxiety.

Strategy in motion

Mercedes-Benz India has been unusually candid about its approach. The brand calls it ‘powertrain-agnostic’ — a phrase that sounds like corporate speak but, in practice, means something useful. The all-new CLA arrived in April 2026 as a born-electric BEV. The S 450e arrives in June as a plug-in hybrid. The EQS continues as a fully electric flagship. The same showroom, three different answers to the same question: what should an electrified luxury car actually be?

The answer Mercedes-Benz offers with the S 450e is the most pragmatic of the three. Daily commutes — the Bandra-to-BKC, the Connaught Place-to-Saket, the Indiranagar-to-Whitefield — run on pure electric for most Indian customers, comfortably inside the 115 km WLTP range. Longer drives — the weekend to Lonavla, the run to Jaipur, the slow Mumbai-to-Pune monsoon crawl — lean on the new Euro 7-compliant 3.0L inline six, with the electric motor stepping in when needed. The owner, or chauffeur, doesn’t actually have to choose. The car does. It is, importantly, not a compromise. Combined output of 320 kW (435 hp) and 680 Nm makes the S 450e more powerful than the petrol-only S 450 4MATIC, which delivers 280 kW (381 hp) and 500 Nm. 0–100 in 5.7 seconds. Top speed electronically limited to 250 kmph. The hybrid premium, in this case, isn’t a upsell. It’s an upgrade.

Two thousand seven hundred reasons

That more than 50 per cent of the S-Class — over 2,700 components — has been newly developed, updated or refined makes this technically a mid cycle refresh. In practice, it is a substantial generational step.

The twin-star DIGITAL LIGHT headlamps use micro-LED technology to project a high-beam illumination field roughly 40 per cent larger than the previous generation, with ULTRA RANGE high beam reaching up to 600 metres ahead, materially changing the driving experience. The radiator grille is 20 per cent larger and now illuminated, accented with three-dimensional chrome stars. The rear tail-lamps carry a new three-chrome-star signature. The whole front face is more imposing than its predecessor.

Inside, MB.OS takes the floor. The same fourth-generation operating system that debuted on the CLA in April now governs the S-Class — a Mercedes-built supercomputer connecting every system into one intelligent ecosystem, with the MBUX Superscreen anchoring the cabin and the AI-based ‘Hey Mercedes’ Virtual Assistant handling the conversation. Google Maps powers the navigation. The Zero Layer interface, refined since its earlier iteration, surfaces the right control at the right moment rather than burying it three menus deep.

Art of the ride

The S 450e is rear-wheel drive only — an interesting choice, given that most S-Class variants sold in India are 4MATIC. Mercedes-Benz frames this as a configuration that ‘prioritises rear passenger refinement’. Translated: the chauffeur-driven Indian flagship is fundamentally a rear-seat experience, and rear-wheel drive — without a front prop-shaft tunnel intruding on the cabin — keeps that experience pure. AIRMATIC air suspension is standard. So is 4.5-degree rear-axle steering, upgradeable to 10 degrees — which cuts the turning circle by almost two metres, a genuinely useful number when extracting two-and-a-half tonnes of S-Class from a tight basement parking lot. The car also uses Car-to-X data, shared by other Mercedes-Benz vehicles through the Mercedes-Benz Intelligent Cloud, to pre-arm the suspension for speed bumps and road imperfections it knows are coming. Indian roads, finally, find themselves spoken to in their own language.

Hallmark of safety

Fifteen airbags. PRE-SAFE Impulse belt pretensioners. An adaptive restraint system that tunes itself per-seat, per-occupant. Mercedes-Benz has, since the W124 of the eighties, treated the S-Class as the technology pilot for the rest of the range — and the S 450e continues that role with conviction.

Where this leaves the segment

The S-Class doesn’t really have rivals in India in the conventional sense. Its competitors are the BMW 7 Series, the Audi A8 in its various reappearances, and — at the top edge — the early-Bentley territory most buyers don’t actually cross-shop. What the S 450e does, instead, is open up an internal dialogue within the S-Class family. Petrol customers can stay petrol. EQS customers can stay electric. And the PHEV now exists for the rapidly expanding group of Indian flagship buyers who want the daily quiet of an EV without the road-trip math.

It is, in many ways, the most Indian-market-shaped S-Class Mercedes-Benz has built. Range-anxious on weekdays, range-confident on weekends. Chauffeur-led across the Bandra-Worli Sea Link, owner-driven through the Western Ghats. Two voices, one car. No compromise either way.

Price of luxury

Launched at INR 2.20 crore for the Launch Edition and from INR 2.38 crore for the MANUFAKTUR Edition (ex-showroom), bookings are open now with deliveries scheduled from Q4.

All figures manufacturer-claimed. WLTP electric range is best-case; actual range varies with driving conditions, temperature and load.
