Mercedes Benz EQS 2026 Review: 574-Mile Range, 800V Charging, and the Luxury Electric Sedan That Left Every Rival Behind

Mercedes Benz EQS 2026 delivers 574 miles of WLTP range, a 122kWh battery, 350kW charging, steer-by-wire, and a 55-inch Hyperscreen in one extraordinary electric sedan.

Range anxiety is a negotiation. Every long-distance EV driver knows it — that quiet calculation happening in the back of your mind between where you are, where you need to be, and how many electrons remain. The 2026 Mercedes-Benz EQS, in its most potent single-motor form, appears designed to end that negotiation entirely.

Five hundred and seventy-four miles. On a single charge. That is not a typo, and it is not a misleading laboratory figure produced under conditions no normal driver would ever encounter. It is the official WLTP rating for the updated EQS 450+, achieved with a 122 kWh battery, a drag coefficient of just 0.20 Cd, and a level of aerodynamic refinement that makes the car more slippery through the air than a Tesla Model S. It puts the EQS roughly 200 miles ahead of the BMW i7, its closest rival in the luxury electric sedan class. That is a gap that cannot be argued away.

But range is not the only story here. The 2026 EQS also brings 800-volt electrical architecture to the lineup for the first time, lifting peak DC charging from 200 kW to 350 kW. It introduces steer-by-wire across the range, replacing the physical steering column with a yoke-style controller and electronic actuation. And it upgrades the rear cabin with 13.1-inch entertainment screens that turn the back seats into something that genuinely earns the word first-class. This is a comprehensively transformed car, even if the body that wraps all of that technology looks almost unchanged from the outside.

Design: Beauty in the Aero

The EQS has always divided opinion on styling. Its softly curved, bubble-like silhouette was a deliberate aerodynamic choice from the start — every curve serving a purpose, every surface optimized to reduce drag rather than to excite the eye. Nothing about that philosophy has changed for 2026. The shape is essentially the same as the car that launched in 2021.

What has changed is the detail. The front end now features an illuminated grille panel that twinkles with dozens of tiny three-pointed stars, giving the car a distinctly contemporary presence at night. The hood star ornament returns, a nod to Mercedes’ heritage that has genuine visual impact. A new range of paint options, including a deeply layered night black metallic, gives the car a gravity that photographs rarely capture adequately. From the outside, this is still not a car that announces itself loudly, but there is something quietly authoritative about a machine this long, this low, and this perfectly resolved in its proportions.

Interior: The 55-Inch Moment

Climb inside and the screen is unavoidable. The MBUX Hyperscreen has always been the EQS’s signature interior statement, but for 2026 it measures 55 inches from one edge to the other — more than four and a half feet of continuous glass spanning the entire width of the dashboard, housing a 12.3-inch driver’s display, a 17.7-inch central infotainment screen, and a 12.3-inch passenger display that functions independently of what the driver sees. It is, by any rational measure, an extraordinary piece of technology.

The updated MBUX operating system inside is faster, more logically organized, and now features a Zero Layer interface that surfaces the most commonly used functions without requiring the driver to navigate through menus. Voice control has improved significantly, responding to natural speech rather than requiring specific command phrases. The system will even respond to the phrase “Hey Mercedes” for climate adjustments, navigation input, and media control while the car is moving.

Material quality throughout is exceptional. Nappa leather, real metal trim, and a level of fit and finish that puts this car in a tier above almost everything short of a Rolls-Royce. The seats deserve specific mention: deeply cushioned, highly adjustable, with built-in massage functions and, on higher specifications, optional headrest pillows that transform a long journey into something genuinely restorative. Rear headroom and legroom are both abundant, and new for 2026, the rear passengers get those 13.1-inch touchscreens along with individual climate and entertainment remotes. If you have ever been a passenger in a business-class airplane cabin and thought it could be improved upon, the back seat of a fully optioned EQS is a reasonable answer.

It is worth noting one point of contention: the new steer-by-wire yoke. It divides the cabin into something that feels genuinely futuristic and something that feels slightly unfamiliar. The yoke replaces the traditional steering wheel with a flat-bottomed, squared-off controller that has no column connecting it mechanically to the front wheels. The steering ratio and effort are managed entirely electronically. On straight highways it is undemanding. In tight parking situations the car’s software handles what would otherwise require significant hand-over-hand steering. Most drivers will adapt within an afternoon. Whether they prefer it is a different question.

Powertrain: The Range Architecture

The 2026 EQS range launches with four configurations. The entry-level EQS 400 carries a 112 kWh battery and a single rear motor, delivering a still-remarkable 507 miles of WLTP range. The EQS 450+, which will be the volume seller, upgrades to the 122 kWh pack and achieves that headline 574-mile figure. The EQS 500 4Matic and EQS 580 4Matic add a second front motor for all-wheel drive, trading some range for quicker acceleration and added traction confidence.

All three upper variants move to 800-volt electrical architecture, a significant upgrade from the 400-volt setup of the outgoing model. This enables DC fast charging at up to 350 kW, meaning a 10-to-80-percent top-up takes around 31 minutes at a compatible high-power charger. In practical American terms, where most public DC fast chargers peak at 150 to 350 kW, this represents a meaningful real-world upgrade. Add ten minutes at a 350 kW charger and you recover more than 100 miles of range. A standard NACS adapter comes included for 2026, providing seamless access to Tesla’s Supercharger network across the United States.

Range: The Number That Changes the Conversation

It is worth spending more time on that range figure, because it changes the practical calculus of ownership in a meaningful way. A realistic real-world range — accounting for highway speeds, climate control, and seasonal temperature variation — will likely land somewhere between 380 and 460 miles for most American drivers in temperate conditions. Even at the lower end of that estimate, the EQS delivers more real-world miles between charges than almost any electric vehicle currently on sale in the United States. The BMW i7, with its 108 kWh battery, manages around 320 miles in similar conditions. The Lucid Air Grand Touring remains the closest competitor in terms of raw range, but comes at a higher price point.

The aerodynamic achievement here is genuine. A 0.20 Cd drag coefficient is a number that normally belongs to purpose-built efficiency concepts, not production luxury sedans capable of carrying four adults in substantial comfort. Mercedes achieved it through an obsessive attention to every surface: flush-fitting door handles, a sealed underbody, optimized mirror aerodynamics, and a roofline that flows into the trunk without a single unnecessary angle. The result is a car that wastes very little energy simply pushing air out of its way at highway speeds, which is where most of a long-distance EV’s range disappears.

Ride, Handling, and the Steer-by-Wire Question

The EQS has always prioritized ride comfort over dynamic engagement, and that fundamental character is unchanged. Air suspension absorbs highway imperfections with a calm, floating quality that rivals the best private jets at cruise altitude. On smoother American interstates, it is an almost uncanny experience — the road surface simply ceases to exist as a concern, and the cabin becomes a sealed world of quiet, warmth, and controlled air.

Previous generations of the EQS drew criticism for being too soft in urban environments, where the suspension occasionally struggled with sharp-edged potholes, sending mild thuds through the cabin. The 2026 car addresses this with revised damper tuning and a new predictive road-scanning function that uses cameras to read the road surface ahead and pre-emptively adjust the suspension. Early reports from European first drives suggest meaningful improvement, though direct comparison on American roads awaits.

The steer-by-wire system is competent and precise, particularly at highway speeds where it delivers a light, confidence-inspiring feel. At low speeds, the software-managed steering ratio makes parking genuinely easier — the car can achieve tighter turns than a conventional setup allows. The yoke itself takes adjustment. Without the familiar round wheel as a reference point, inputs initially feel less intuitive. Most drivers report that this passes within the first few hours. Whether it is preferable is genuinely subjective, and for buyers who feel strongly, it is worth spending time in a dealer car before committing.

The BMW i7 remains the more satisfying car to drive, particularly on a winding road where its more conventional dynamics reward active input. But the EQS was never designed to compete on that axis. It is a long-distance grand tourer in the truest sense — a machine optimized for the experience of covering enormous distances in absolute comfort, with minimal stops and minimal effort.

Technology and Safety

The updated MB.OS operating system represents Mercedes’ most serious attempt yet at building a truly integrated software platform. Functions that previously required multiple menu steps now surface automatically based on context — the navigation adjusts without being asked when traffic conditions change, climate preferences are remembered and applied at startup, and the driver monitoring system now also reads ambient temperature and humidity to optimize interior comfort. Over-the-air updates will continue to develop the system post-purchase.

The new MBUX Virtual Assistant is a meaningful upgrade from its predecessor. It responds to natural, conversational language rather than specific trigger phrases, and can handle multi-part requests without requiring separate commands. Ask it to find a charging stop that also has a restaurant nearby, and it integrates both into the navigation route in a single request.

Safety technology is comprehensive: autonomous emergency braking, active blind-spot monitoring, rear cross-traffic alert, lane centering assist, adaptive cruise with stop-and-go capability, and a driver monitoring system that watches for fatigue and distraction. The 360-degree camera system now offers higher resolution, and the parking function has been expanded to include memory parking — the car can learn and repeat a specific parking maneuver on its own.

US Pricing and Value

The 2026 Mercedes-Benz EQS enters the American market starting at approximately $101,150 for the EQS 450+. The all-wheel-drive EQS 580 4Matic commands a premium, with a starting price near $125,000. These are not cars for the general market, and Mercedes makes no pretense otherwise. At these prices, the EQS competes directly against the BMW i7, Lucid Air, Porsche Taycan, and the Tesla Model S Plaid for buyers who prioritize electric propulsion and are unwilling to compromise on refinement.

Against the i7, the EQS makes a compelling case on range and interior technology, though the BMW remains the more engaging driver’s car. Against the Lucid Air, the EQS carries the weight of a recognizable luxury brand and an established dealer service network. Against the Taycan, the range advantage is overwhelming. Against the Tesla, the argument is purely about whether software and range trump material quality and build precision — and for many buyers in this price tier, they do not.

The EQS has faced scrutiny for its depreciation curve since launch, and residual values remain a legitimate concern for buyers who lease or plan to sell within three years. Mercedes has addressed this partially by delivering a more substantial update than a typical mid-cycle facelift, and by introducing technology that keeps the car competitive through to its expected replacement by a purpose-built electric S-Class around 2030.

EV Pulse Verdict

The 2026 Mercedes-Benz EQS is the most technically advanced luxury electric sedan money can buy. Its 574-mile range is a genuine landmark achievement, its interior is peerless in the electric segment, and the upgrade to 800-volt fast charging finally gives it the charging credentials its ambitions demanded. The steer-by-wire yoke and unchanged exterior styling are debating points, not dealbreakers. If covering vast distances in exceptional comfort, with a cabin that makes business class feel ordinary, is what you need from an electric vehicle — nothing else comes close.
