Mercedes-Benz S450e PHEV launch: Why It’s the Ultimate Tech-Forward Sedan
Preferred by heads of state, oligarchs and tech bros unanimously across the globe, the S-Class is different things to different powerful people. It’s either a statement of success or the quiet tech flex if you opt for the AMG variants of the uber-saloon. As Mercedes-Benz (India) CEO, Santosh Iyer emphasised during the new S-Class launch, Mumbai has had a special relationship with this model over the decades, even before the brand set up base in India.
Since its first formal incarnation in 1954, it has unapologetically used the finest materials, the most advanced engineering, and the heaviest investment in occupant comfort. Seven decades and a dozen generations later, Mercedes-Benz India has launched the S450e, the first plug-in hybrid ever offered in the flagship sedan for our market.
At Rs. 2.20 crore for the Launch Edition and Rs. 2.38 crore for the bespoke MANUFAKTUR Edition, it is not just a mere nip and tuck job. With more than 2700 new or revised components, it is practically a new car wearing a very familiar face. Deliveries are slated to begin in Q4 2026, so if you’re short of a couple of big ones, you have some time to save up.

The Electric Argument
The S450e pairs a Euro 7-compliant 3.0-litre inline-six with a 120kW electric motor to produce a combined 435hp and 680Nm of torque. The sprint to 100km/h takes 5.7 seconds, propelled only by the rear wheels, which is brisk. Thanks to its generous 22kWh battery, the more meaningful number is 115km of pure electric range, enough to cover a typical daily work commute without the combustion engine waking up at all. With a claimed average of 32 km/litre, even if you do wake up the six-cylinder engine, the intelligent battery management system will turn on the Battery Hold feature to preserve EV range and coast along with ICE power on longer stretches. It is also the first PHEV to support fast charging up to 60kW DC, so topping up the battery should no longer be the overnight exercise it once was.
CLA Started It, S-Class Scales It
The electric CLA, launched earlier this year, was the first Mercedes to run the full MB.OS platform, with four NVIDIA supercomputers monitoring and controlling the ADAS, powertrain, infotainment and Connectivity functions. But the S-Class feels like it has been architected for the long game toward Level 4 autonomy.
The India-bound S450e will come equipped with 15 airbags, including front-facing airbags for rear passengers, seat belt airbags, 13.1-inch rear OLED screens with gesture-sensing cameras, and a 4D Burmester surround system running 1610 watts through 31 speakers and eight body-mounted exciters. Dolby Atmos via the native Apple Music and Amazon Music support will come as standard.
The Supercomputer Inside
Strip away the leather and the Burmester and the Manufaktur paint options though and what you find is one of the most sophisticated computing platforms in any production vehicle. MB.OS, Mercedes’ in-house operating system, runs on the NVIDIA DRIVE AGX Orin SoC. That chip processes 254 trillion operations per second and sits at the centre of a system managing 27 ADAS sensors, active air filtration rated at 99.9% purification, and intelligent AIRMATIC suspension that communicates with the Mercedes-Benz cloud to anticipate road imperfections before the wheels encounter them. Car-to-X data shared by other vehicles on the fleet tells the suspension what is coming. On Indian roads, this can be the difference between a novelty feature and a genuine quality-of-life argument.
The MBUX Superscreen brings a generative AI voice assistant capable of natural conversation in 27 languages, augmented reality navigation via Google Maps, and a Zero Layer interface designed to surface contextual information instead of you digging through menus. Even the familiar “Hey Mercedes” assistant is now powered by large language models, which means it handles context and follow-up questions in a way that the old keyword-detection approach simply could not.
A dream called CarPlay Ultra
Since MB.OS spans multiple domains like infotainment, EV battery management, automated driving, and vehicle functions simultaneously, handing the entire cockpit experience to Apple’s interface would mean surrendering control of all four. So it’s safe to assume that Mercedes has abandoned support for the Ultra tier of CarPlay that commandeers the instrument cluster, climate controls, and virtually every screen in the cabin. Standard CarPlay remains on board, and Mercedes has partnered with Google instead for navigation and machine-learning capability, baked into its own MB.OS.
BMW scores on screen
The S-Class’s most fierce competitor, the BMW 7 Series, is not sitting idle, though. With its 31.3-inch 8K Theatre Screen with integrated Amazon Fire TV, it delivers the superior rear-seat theatrical experience and the one trick the S-Class simply cannot counter. Dual 13.1-inch OLED screens in the rear are great, but they are not cinematic, and the 2026 7 Series facelift also arrives with a pillar-to-pillar Panoramic Vision display and more aggressive power outputs across the range.
Rising above the rest
None of that changes the fundamental argument of an S-Class purchase, though. It dominates in safety tech and pure engineering marvels like the micro-LED DIGITAL LIGHT headlamps that project up to 600 metres ahead! Or the rear axle steering that turns the rear wheels up to 10 degrees, optionally, trimming the turning circle by nearly two metres. To top it all off, the Manufaktur Edition offers a depth of personalisation that no competitor’s options list quite replicates. With a back seat that has been refined over 70 years, the S-Class remains the best mobile office the Indian market has to offer. Competitors have screens, but this car has a legacy and a very fast supercomputer running it!
