Model Nomenclature

The 2027 EQS Sedan is offered in three models.

EQS 450+ Sedan

EQS 450+ Sedan is the rear-wheel-drive model. Its permanently excited synchronous electric motor produces 402 hp and 372 lb-ft of torque, with a manufacturer-stated 0–60 mph time of 5.7 seconds. Standard equipment includes the MBUX Hyperscreen, AIRMATIC air suspension with intelligent damping, 4.5-degree rear-axle steering, heated power rear seats, and rear wireless charging.

EQS 500 4MATIC Sedan

EQS 500 4MATIC Sedan adds a second electric motor and fully variable 4MATIC all-wheel drive with Torque Shift. Combined output is 469 hp and 553 lb-ft of torque, with a manufacturer-stated 0–60 mph time of 4.3 seconds. Mercedes-Benz lists a 39.1-foot wall-to-wall turning circle with standard 4.5-degree rear-axle steering.

EQS 580 4MATIC Sedan

EQS 580 4MATIC Sedan uses dual electric motors producing 576 hp and 590 lb-ft of combined torque. Mercedes-Benz lists a manufacturer-stated 0–60 mph time of 3.9 seconds. Standard 10-degree rear-axle steering reduces the wall-to-wall turning circle to 35.8 feet.

Pinnacle Trim is available for shoppers seeking additional rear-seat comfort and convenience equipment. Mercedes-Benz also offers an AMG® Line with exterior and interior appearance upgrades. Equipment availability can vary by model and configuration.

Performance and Powertrain

All three 2027 EQS Sedan models use the new 122 kWh usable lithium-ion battery and 800-volt electric architecture. A two-speed transmission is used on the primary rear drive unit, with the first gear supporting acceleration from a standstill and the taller second gear supporting higher-speed efficiency and power delivery.

Mercedes-Benz currently lists maximum DC charging at 350 kW on compatible 800-volt equipment and 175 kW on compatible 400-volt equipment. Current model-specific technical data lists an estimated 27-minute 10–80% DC charging time. AC charging operates at 9.6 kW, with approximately 15 hours listed for a 10–100% charge. Charging times vary with battery temperature, state of charge, charging equipment, ambient conditions, and other factors.

The current model-specific U.S. specifications list a North American Charging Standard, or NACS, DC connection and J1772 AC connection.

The new drive architecture also supports recuperation of up to 385 kW under suitable conditions. Drivers can adjust recuperation levels using the steering-wheel controls or gear selector while the vehicle is in Drive.

AIRMATIC air suspension with intelligent damping is standard across the lineup. When applicable Car-to-X services are active, road-condition information from other connected Mercedes-Benz vehicles can help the damping system prepare for certain upcoming surface irregularities. Connected functions depend on available cellular and GPS service and applicable Digital Extras requirements.

Interior, Comfort, and Cargo

The 2027 EQS Sedan seats five passengers across a 126.4-inch wheelbase. Published dimensions include 41.6 inches of front legroom, 40.4 inches of rear legroom, 59.5 inches of front shoulder room, and 59.1 inches of rear shoulder room. Cargo capacity ranges from 22 to 63 cubic feet with the rear seats configured for additional storage.

Heated power rear seats and rear wireless charging are standard. Heated and ventilated power front seats are also offered, while available equipment can add multicontour front seats with massage, heated front seatbelts, additional rear-seat comfort functions, and expanded climate-control features.

A HEPA filter is part of the updated air-management system. Mercedes-Benz says the filter can remove more than 99.65% of particles from incoming air, while activated-carbon filtration also helps reduce certain gases and odors.

The MANUFAKTUR Made to Measure program offers more than 100 exterior paint colors along with additional upholstery and interior personalization choices.

Technology and Infotainment

The standard MBUX Hyperscreen is a central technology feature of the 2027 EQS Sedan. Three active display areas sit beneath a single glass surface measuring more than 55 inches across: a 12.3-inch driver display, 17.7-inch central display, and 12.3-inch front-passenger display.

The latest MBUX system operates with MB.OS and incorporates artificial intelligence into the MBUX Virtual Assistant. Mercedes-Benz says the assistant can conduct complex, multi-turn conversations and retain conversational context during supported interactions.

MBUX Surround Navigation can use cameras and sensors to present a real-time 3D representation of the vehicle's surroundings on the driver display. Navigation uses Google technology, while Digital Extra: MBUX Navigation with Electric Intelligence can consider traffic, topography, charging opportunities, vehicle energy use, and other factors when planning a route.

Mercedes-Benz currently lists seven years of services with Digital Extra: MBUX Navigation with Electric Intelligence. That seven-year term should not be interpreted as applying to every connected or Digital Extra service in the vehicle.

The available steer-by-wire system removes the conventional mechanical steering-column connection to the front wheels and uses electronic control to vary steering ratio and effort. Mercedes-Benz identifies the new EQS as the first series-production vehicle from a German automaker available with steer-by-wire. Standard electromechanical steering remains available as well.

Available MBUX High-End Rear Seat Entertainment uses two approximately 13-inch displays with additional controls for supported entertainment and comfort functions.

Next-generation DIGITAL LIGHT is standard and incorporates micro-LED technology, Ultra Wide high beam, and Partial High Beam Function. The system can adapt illumination around detected road users under supported conditions.

Digital Extra: Digital Vehicle Key can provide compatible smartphone-based locking, unlocking, and vehicle-start functionality. Device, operating-system, account, connectivity, and service requirements apply.

Safety and Driver Assistance

PRE-SAFE® is standard on the EQS Sedan. Under certain detected pre-collision conditions, PRE-SAFE can initiate selected occupant-protection measures such as adjusting front-seat and seatbelt settings and activating PRE-SAFE Sound when the audio system is operating. The system cannot prevent every collision.

The 2027 EQS uses a sensor suite consisting of:

10 external cameras
Up to five radar sensors
12 ultrasonic sensors

These sensors work with a high-performance control unit operating through MB.OS to support driver-assistance and parking functions.

Digital Extra: MB.DRIVE ASSIST and Digital Extra: Distance Assist DISTRONIC® are included standard according to Mercedes-Benz 2027 launch information. Additional functions include Steering Assist, Lane Change Assist, Evasive Steering Function Plus, and Proactive Lane Change Assist under supported conditions.

2027 Mercedes-Benz EQS Sedan safety and driver assistance

MB.DRIVE PARKING ASSIST and MB.DRIVE PARKING ASSIST 360 are also listed as standard Digital Extras. Parking-assistance and driver-assistance systems operate within defined limitations and do not replace attentive driving or direct observation of people, vehicles, animals, curbs, or other obstacles around the vehicle.
