Meet the 2027 Mercedes-Benz EQS: A First Look for Ontario Drivers
April 17 2026,
Mercedes-Benz built the EQS to prove that electric luxury doesn't mean compromise. The 2027 model is the first German series production car with available steer-by-wire technology, featuring a completely new electric architecture built around 800-volt charging, a 122 kWh battery, and an AI-powered operating system that learns as you drive.
Ontario drivers will appreciate the practical side just as much as the technology. The EQS 450+ is rated at up to 925 km of range (WLTP) - though Canadian NRCan ratings are pending and typically run 15-25% lower than WLTP figures. When you do charge, 800-volt DC fast charging adds up to 320 km of range in 10 minutes. The EQS arrives at Canadian dealerships in the second half of 2026 in three trims: EQS 450+, EQS 500 4MATIC, and EQS 580 4MATIC.
How the New Electric Architecture Changes the Experience
The 2027 EQS is built on a new 800-volt electric platform that changes how the vehicle charges, drives, and uses energy. The 122 kWh battery uses silicon oxide-blended anodes, storing more energy per kilogram than previous graphite-only designs for more range in the same physical size.
All three trims feature the new battery and 800-volt architecture. The EQS 450+ delivers up to 925 km of range (WLTP), while the EQS 500 4MATIC and EQS 580 4MATIC add dual-motor all-wheel drive. The rear-axle motor includes a two-speed transmission - first gear handles acceleration from standstill, while second gear optimizes highway efficiency and the electronically limited 209 km/h top speed.
Recuperation power has increased to 385 kW, recovering significantly more energy during braking. You can adjust recuperation levels using steering wheel paddles or the gear selector. At higher settings, the vehicle can slow to a stop using regenerative braking alone.
The First German Production Car with Steer-by-Wire
The 2027 EQS offers optional steer-by-wire technology - a first for a German automaker in series production. Instead of a mechanical connection between steering wheel and front wheels, the system uses electronic signals and redundant control units to translate steering input into wheel movement.
The system eliminates vibrations from uneven road surfaces that would normally transmit through the steering column. The steering ratio adjusts automatically based on speed - tighter at low speeds for easier parking, more stable at highway speeds. The flatter steering wheel design opens up more driver space and improves display visibility.
Steer-by-wire works with standard rear-axle steering. At higher speeds, rear wheels steer parallel to front wheels to enhance stability. The system includes redundant signal paths and can maintain lateral control through rear-axle steering and targeted wheel braking if needed.
MB.OS and the AI-Powered Supercomputer
The 2027 EQS introduces Mercedes-Benz Operating System (MB.OS), which replaces the previous infotainment architecture. MB.OS integrates and controls every vehicle aspect - from powertrain management to driver assistance to entertainment. The system is built on a supercomputer with AI algorithms trained on fleet data and supports over-the-air updates for entire vehicle software.
The MBUX Virtual Assistant conducts complex dialogues and responds to natural language commands. Various avatars provide personal interaction, and the system learns your preferences over time. The standard MBUX Hyperscreen merges three digital displays beneath a single continuous glass surface spanning over 55 inches.
Rear passengers can access the optional MBUX High-End Rear Seat Entertainment system with two 13-inch displays and new MBUX remotes for controlling comfort functions and personalized entertainment.
Driver Assistance and Safety Systems
The 2027 EQS uses up to 27 sensors - 10 external cameras, five radar sensors, and 12 ultrasonic sensors - to monitor the surrounding environment. These sensors feed data to a high-performance control unit running on MB.OS, processing information using AI algorithms.
MB.DRIVE ASSIST with Steering Assist, Lane Change Assist, and Distance Assist DISTRONIC is standard. Evasive Steering Function Plus can automatically steer around objects when the system detects collision risk within your lane. Proactive Lane Change Assist offers automated lane changes during highway driving.
MB.DRIVE PARKING ASSIST 360 with a 360-degree camera is standard. The system detects parking spaces on both sides, including spots without marked lines, and assists when leaving - even if you parked manually. The Reverse maneuvering function can automatically reverse part of your most recent route, useful in tight situations. Rim protection warning displays top-view distance alerts when maneuvering in tight spaces.
Design and Personalization
The 2027 EQS features a new illuminated Mercedes-Benz standing star on the hood. Striking hood powerdomes and star design daytime running lights characterize the front end. The available package adds a dynamic illuminated radiator grille with backlit star pattern and illuminated central star.
The new generation DIGITAL LIGHT with Ultra Wide high beam creates a larger, high-resolution field of illumination and is up to 50% more efficient. The system introduces partial high beam function on the EQS in North America for the first time.
Inside, new black wood trim with fine-line structure adds an expressive touch. Iconic laurel stitching in Macchiato Beige/Space Grey echoes the Mercedes-Benz emblem. The Exclusive Nappa Leather Package offers fine Nappa leather throughout the cabin.
The MANUFAKTUR Made to Measure program offers extensive personalization with more than 100 paint colours, including MANUFAKTUR Black Sparkling with glass flakes and MANUFAKTUR Verde Silver Magno with a sophisticated matte finish.
Comfort Features That Matter in Ontario Winters
The 2027 EQS includes advanced seatbelt heating for front seats - providing soothing warmth in cold weather. A HEPA filter cleans incoming air, filtering up to 99.65% of particles. AIRMATIC air suspension with cloud-based damper regulation enables the EQS to glide over speed bumps, automatically adjusting damping before reaching obstacles.
With a drag coefficient of only 0.20, the EQS remains one of the most aerodynamic production cars ever built. The frontal area is 2.51 m², resulting in an effective resistance area of 0.5 m² - less than a road cyclist experiences.
The EQS Defines Electric Luxury for a New Era
The 2027 Mercedes-Benz EQS pairs competitive range, ultra-fast charging, and AI-powered intelligence in a package that looks and feels unmistakably Mercedes-Benz. If you're ready to experience the future of electric luxury, pre-order the 2027 EQS at Mercedes-Benz Ottawa Downtown in Ottawa.
