Key Takeaways:
– Mercedes-Benz has significantly updated its EQS sedan for its mid-cycle refresh.
– The updated EQS boasts an 800-volt architecture, leading to extended range and faster charging capabilities.
– New technological features, including an optional steer-by-wire system, are now available.
– Despite improvements, the car’s core exterior design remains largely unchanged, which may still be a point of contention for some consumers.
Mercedes-Benz has unveiled a comprehensive mid-cycle update for its EQS sedan, aiming to bolster its position in the competitive electric luxury vehicle market. While the exterior may appear familiar, the German automaker has introduced substantial improvements to the platform, powertrain, and technological offerings, positioning the refreshed EQS as a more compelling EV option.
## Significant Platform and Performance Enhancements
The most notable upgrade to the EQS is its transition to an 800-volt electrical architecture, a significant leap from the previous 400-volt system. This fundamental change underpins the vehicle’s enhanced performance metrics. The new platform enables the EQS to achieve a peak charging power of up to 350 kilowatts, surpassing its previous capabilities and aligning it with the latest advancements in EV charging technology.
This higher charging speed translates to tangible benefits for owners. On an 800-volt charging station, the EQS can now replenish its battery to gain approximately 199 miles (320 km) of WLTP range in just 10 minutes. While charging speeds on a 400-volt charger are capped at 175 kW, the 800-volt capability represents a substantial advancement for long-distance travel and quick top-ups.
### Extended Range and Efficiency Gains
Fueling these performance improvements is a slightly larger 122-kilowatt-hour battery, an increase from the prior 118 kWh capacity. Combined with the inherent efficiency benefits of the 800-volt system and the addition of a two-speed transmission for the rear motor, the EQS now claims the title of the longest-range Mercedes EV. The single-motor EQS 450+ variant is rated for an impressive WLTP range of 575 miles (925 km).
While WLTP (Worldwide Harmonised Light Vehicle Test Procedure) figures are generally more optimistic than U.S. EPA (Environmental Protection Agency) estimates, the projected EPA range is still expected to be highly competitive. Official EPA figures for the updated model are forthcoming.
## Advanced Technology Integration
The updated EQS also introduces a range of new technological features, enhancing both the driving experience and vehicle functionality. Among the most significant is the optional steer-by-wire system, which replaces the traditional steering wheel with a yoke. This system allows for more precise control with reduced steering input, making maneuvers feel more intuitive.
Opting for the steer-by-wire system also increases the rear-wheel steering angle to 10 degrees, up from the standard 4.5 degrees. This enhanced articulation significantly improves the vehicle’s maneuverability, particularly in tight urban environments. Owners can also opt for the 10-degree rear steering without the steer-by-wire system, maintaining a similar feature from the previous model.
### Enhanced Regenerative Braking and Powertrain Efficiency
Regenerative braking has also seen a notable upgrade, with the EQS now capable of recovering energy at up to 385 kilowatts. This aggressive energy recuperation contributes to overall efficiency and reduces wear on the traditional friction brakes. It is anticipated that, similar to other recent Mercedes-Benz EVs like the GLC EV, the electric motors will handle the vast majority of braking duties, with friction brakes playing a minimal role.
### The New MB.OS and Hyperscreen Experience
The integration of the new MB.OS operating system marks another key advancement. Running on the expansive 55-inch ‘Hyperscreen’ – a seamless display comprising three individual screens – the updated EQS gains access to the latest software features. These include advanced multi-agent artificial intelligence, enhanced integration with Google Maps, and expanded over-the-air (OTA) update capabilities.
Furthermore, the vehicle’s driver assistance systems have been refined. Equipped with 27 sensors and cameras, the EQS now offers an optional feature that allows it to automatically steer around obstacles, enhancing safety and convenience.
## Subtle Exterior Refinements and Interior Comforts
Visually, the updated EQS is distinguished by a revised front-end design. It features a more prominent simulated grille and a subtly redesigned hood. The daytime running lights have been updated to incorporate the Mercedes star emblem and utilize upgraded Digital Light technology, which provides improved illumination while consuming 50% less power, according to the manufacturer.
The rear lighting elements have also received subtle design tweaks, featuring a new spiral-like LED pattern designed to enhance the vehicle’s visual width and overall sense of luxury. While these changes are understated, they aim to provide a refreshed aesthetic.
Inside, the EQS will offer heated seatbelts, a feature previously seen in the S-Class. Mercedes-Benz highlights this not only as a comfort feature for colder climates but also as a safety enhancement, encouraging occupants to wear seatbelts correctly even with bulky winter clothing, thus ensuring optimal performance of the restraint systems in a collision.
## Addressing the Persistent Design Question
Despite the extensive technological and performance upgrades, the fundamental exterior design of the EQS remains largely unchanged. Its distinctive, aerodynamically optimized ‘one-bow’ or ‘egg-like’ silhouette, while efficient, has been a point of discussion since its initial launch. Whether these comprehensive improvements will sway potential buyers who may have been hesitant due to the styling remains to be seen.
Mercedes-Benz emphasizes that the combination of new technologies, enhanced performance, and improved efficiency represents a significant evolution of the EQS. The steer-by-wire system, in particular, is noted for providing a demonstrably different and more engaging driving feel compared to the pre-update model. For consumers who can look beyond the established exterior design, the refreshed EQS presents itself as a sophisticated and technologically advanced electric luxury sedan.
