2023 Mercedes-Benz EQS Assessment, Pricing, and Specs

The 2023 EQS sedan is available in three different configurations with three different powertrains and three trim levels. We’d recommend the top Pinnacle trim in the rear-wheel drive EQS450+ guise, which provides niceties such as heated-and-ventilated front and rear seats, massage for the front seat passengers, four-zone automatic climate control, a head-up display, and more. While it only makes 329 horsepower, the entry-level powertrain packs plenty of punch, plus it can now be paired with the brand’s all-wheel drive system if a buyer feels so inclined, which also ups the output significantly.

EV Motor, Power, and Performance

The EQS450+ features an electric motor mounted on its rear axle that generates 329 horsepower and 406 pound-feet of torque. The EQS580 4Matic has an electric motor on each axle, which translates to all-wheel drive and a total system output of 516 horsepower and 611 pound-feet of torque. The new EQS450 4Matic slots in between the two aforementioned models and offers all-wheel drive capability and more power output to go with it: The 4MATIC model brings 355 horsepower, up from 329 and—more noteworthy—590 pound-feet of torque, an impressive jump from the rear-drive car’s 417. In our testing, the EQS450+ accelerated from zero to 60 mph in 5.4 seconds. The more powerful EQS580 hit 60 mph in just 3.7 seconds in our testing. Every EQS rides on an adaptive air suspension and rolls on rims that range in size between 19 and 21 inches. A Standard rear-axle-steering system can angle the rear wheels up to 4.5 degrees, and there’s an optional upgrade that can turn them 10 degrees. This technology is intended to both make the 205.4-inch-long sedan easier to maneuver in tight spots and increase its stability at high speeds. Based on our time behind the wheel, the EQS exhibits a quiet cabin and silken ride quality, but we take issue with the car’s disconnected-feeling brake pedal and wish its operation felt more natural. Luckily, activating the car’s adjustable regenerative braking system allows the driver to avoid needing to step on the limp brake pedal for the most part, letting the system recapture energy by aggressively slowing the car when the driver lifts off the throttle.

Range, Charging, and Battery Life

All EQS models feature a lithium-ion battery pack with a usable capacity of 107.8 kWh. The EPA rates the EQS450+ at 350 miles of range and the EQS580 at 340 miles. Along with the ability to charge the battery from 10 to 100 percent in approximately 11 hours and 15 minutes using a 240-volt (Level 2) charger, the EQS can supposedly replenish 70 percent of its battery–from 10 to 80 percent­–in about 35 minutes using a DC fast charger. On our 75-mph highway fuel-economy test route, which is part of our extensive testing regimen, we observed an impressive 350 miles of range in the EQS580.

Fuel Economy and Real-World MPGe

According to the EPA, the most efficient EQS model is the EQS450+, which earned ratings of 97 MPGe city, 97 MPGe highway, and 97 MPGe combined. Going with the EQS580 drops the city figure to 92 MPGe city but increases the highway estimate to 99 MPGe, for a combined rating of 95 MPGe. We expect ratings to remain the same for the 2023 model year since no major changes have been made, and the new EQS450 4Matic should land somewhere in between the ratings of the other two models.

Interior, Comfort, and Cargo

Inside, the EQS is lined with beautiful, high-quality materials and outfitted with countless luxury amenities. The roster of desirable features includes extensive ambient interior lighting, headrest pillows for front and rear passengers, and an Executive Rear Seat package. The latter includes adjustable back seats with massage functions, neck and shoulder heating, and an individual tablet to control the MBUX infotainment system. Still, the most notable option is what Mercedes calls Hyperscreen: a giant wall-to-wall panel of glass that stretches across the instrument panel and encompasses the infotainment system. While this digitized dashboard looks futuristic, the EQS does come standard with a more traditional dashboard. Thanks to a completely flat floor and a lengthy 126.4-inch wheelbase, the EQS has a spacious interior. Cargo space is also especially generous, thanks to its large hatchback.

Infotainment and Connectivity

The MBUX infotainment system on the EQS is one of its most prominent interior features, especially the 56-inch-long Hyperscreen. While the standard arrangement is a tablet-like touchscreen that extends from the center console and floats above the dashboard, the optional Hyperscreen acts as one massive display that consists of three distinct screens. These include the 12.3-inch gauge cluster, the 17.7-inch central touchscreen, and the 12.3-inch passenger-side touchscreen. Along with the dazzling array of screens, the EQS features a fingerprint scanner that activates individual driver profiles, the “Hey Mercedes” voice-command system, and augmented-reality navigation in the head-up display. Every model also includes six USB-C ports throughout the cabin and a Burmester audio system.

Safety and Driver-Assistance Features

The 2023 EQS comes packed with standard driver-assistance technology, including adaptive cruise control and self-parking assist. For more information about the EQS’s crash test results, visit the National Highway Traffic Safety Administration (NHTSA) and Insurance Institute for Highway Safety (IIHS) websites. Key safety features include:

• Standard automated emergency braking with pedestrian detection
• Standard lane-departure warning and lane-keeping assist
• Standard blind-spot monitoring

Warranty and Maintenance Coverage

Mercedes’ limited and powertrain warranties are competitive with other German automakers, but its terms aren’t particularly noteworthy. There’s also no complimentary maintenance, which is something BMW offers.

• Limited warranty covers four years or 50,000 miles
• Powertrain warranty covers four years or 50,000 miles
• Electrical components are covered for 10 years or 155,000 miles
• No complimentary scheduled maintenance
