History Made: Mercedes-Benz EQS
Mercedes-Benz has long been seen as the leader in trickle-down technology being seen in cars some years after featuring in the brand’s higher end saloons such as the S-Class. And with the release of their first all electric luxury vehicle, the EQS, this tradition is set to continue.
The EQS will offer ranges of up to 770 kilometres and will pack a powertrain of up to 385kW. A performance version is said to be in development and with up to 560kW. It will sit within the expectations of the S-Class saloon segment. The vehicles will be rear axle driven however the models fitted with the 4MATIC will have a front axle engine also.
Mercedes says the initial models will be the EQS 450+ with 245 kW and the EQS 580 4MATIC with 385 kW. The rated power consumption rates are quoted as 20.4-15.7 kWh/100 km, and 21.8-17.4 kWh/100 km. New technology for the batteries has them enabled with a higher energy density. Of the two batteries to be available, the larger will have a usable energy content of 107.8 kWh. Mercedes says this is around 26 percent more than the EQC, their EV SUV.
It’s tech that is bespoke for M-B, with the software having been fully developed by the company and allowing over the air updates. This keeps the management system up to date, and for the life cycle of the battery. In respect to the charging rates, the DC fast charge stations pump in 200kW( and 300km in around 15 minutes. On a home charger system the EQS charges up to 22kW with AC power. The software will also allow intelligent charging programs and battery-saving charging.
A key component of EV technology is is energy recuperation. The EQS uses a program called DAuto, which can recuperate energy from deceleration to zero without the need for the brake pedal to be utilised. Smart cruise tech employs the same mechanisms with vehicle traffic ahead of the EQS. Intelligent energy recovery is situation-optimised with the aid of ECO Assist and acts with foresight, taking into account traffic conditions or topography, among other things, and up to 290kW can be generated. The driver also can set three energy recovery levels and the coast function via paddle shifters on the steering wheel.
Also available as OTA or over the air will be the activation of vehicle functionalities. This includes two driving programs for younger aged drivers and for service staff. Light entertainment in the installation of games will also be available. Plus the updates will allow personal preference settings such as changing the steering angles for the rear wheel steering from the standard 4.5 degrees to the maximum 10 degrees. Planned is the activation of subscription services and testing on future programs.
Aerodynamics plays a big part in vehicle fuel efficiency and the new EQS has plenty of aero in the design. in fact, it’s currently rated as the most aerodynamic car available with a drag coefficient of 0.20cD. In conjunction with that slippery body is the reduction of wind noise at speed, improving comfort levels.
The need for aero is due to the EQS being on a new chassis architecture to provide a home for the powertrain. Mercedes-Benz calls the design language Sensual Purity, with smooth, organic, lines, a reduction in the join lines in panels, the fastback styling. The front end is a “Black Panel” look with the headlights running seamlessly into the grille panel which can be optioned with a 3D star pattern to complement the three-pointed Mercedes star.
Embedded throughout the EQS is a network of sensors, up to 350 of them, depending on specification. Amongst the types of information recorded are distance travelled, ambient lighting conditions, acceleration rates and speeds achieved. AI then utilises these datasets to adjust the car on the fly. This includes monitoring the battery charge levels in respect to the distance required to see the next charging point thanks to the onboard Navigation with Electric Intelligence.
Being a class-setting EV, the EQS packs in some high-end green technology for the passengers. An example is the HEPA filter than can be set to fully clean the air inside the cabin before passengers enter with the onboard data system, MBUX, able to display particulate levels inside and out. Recycled materials are used in areas such as the carpets. The manufacturing process is fully carbon-offset as well.
The MBUX Hyperscreen is the absolute highlight in the interior. This large, curved screen unit sweeps almost from A-pillar to A-pillar. Three screens sit under a cover glass and appear to merge into one. The 12.3-inch OLED display for the front passenger gives him or her their own display and control area. The entertainment functions are only available there while the car is being driven in accordance with the country-specific legal regulations. Mercedes-EQ relies on an intelligent, camera-based locking logic: if the camera detects that the driver is looking at the front passenger display, it is automatically dimmed.
As part of its Ambition 2039 initiative, Mercedes-Benz is working on offering a carbon-neutral new car fleet within 20 years from now. By as early as 2030, the company wants more than half the cars it sells to feature electric drive systems – this includes fully electric vehicles and plug-in hybrids. In many areas, Mercedes is already thinking about tomorrow today: the new EQS is designed to be correspondingly sustainable. The vehicles are produced in a carbon-neutral manner, and resource-saving materials such as carpets made from recycled yarn are used. This is because Mercedes-Benz considers the entire value chain, from development and the supplier network to its own production. Mercedes-Benz AG has had its climate protection targets confirmed by the Science Based Targets Initiative (SBTI).
