Performance & Safety
Because they don’t have a gasoline engine, Mercedes-Benz: All Electric vehicles have electric motors that deliver instant torque and quick acceleration. Certain vehicles such as the EQS have a longer wheelbase for more stability and comfortable ride as well as more interior space. Due to the battery being at the bottom of the car, Mercedes-Benz: All Electric vehicles also have lower center of gravity, making them more stable which minimizes the chance of rollover while improving handling and cornering.
Internal Mercedes-Benz safety standards requires their vehicles to meet or exceed legal requirements. Strict requirements and testing for the battery and all components carrying electrical current also apply, including analyzing battery behavior under shock load and in the event of it being penetrated by foreign objects as well as overheating and overcharging simulation testing.
To protect the cells in the battery, the battery sits in a crash-protected area in the underbody, embedded in the body shell structure including an extruded aluminum profile on the side. This provides protection against punctures and side impacts. A battery guard in the front area of the battery provides extra reinforcement to prevent the energy storage unit from being pierced by foreign objects.
In addition, there is a separate, multi-level battery management safety system that continuously monitors temperature, voltage or insulation for everyday operation. If an error occurs, the battery is switched off.
In the event of an accident on certain conditions, every Mercedes-Benz: All Electric vehicle automatically disconnects its high voltage system to prevent the vehicle from explosion. A low-voltage circuit stays on to power the displays and the car’s communications systems to allow calling of emergency response numbers like 911.
Cost of Ownership
While it may be a significant investment initially, the ability to charge at home using a Level 2 charger over time will save thousands of dollars in mobility costs compared to those of an internal combustion engine vehicle.
Maintenance
Owning an electric vehicle usually requires less maintenance than traditional gasoline cars. Mercedes-Benz offers great warranties for the lithium-ion battery: 10yr/155,000 mile warranty for the EQE and EQS models; 8yr/100,000 mile warranty for the EQB models as well as complimentary comprehensive coverage with your first scheduled maintenance at 2 years/20,000 miles.
After that it is recommended your electric vehicle comes in for service including brake fluid replacement, dust filter replacement, and battery and cable charging inspection every 20,000 miles. Tire rotation is recommended for every 10,000 miles. Additional maintenance services such as cleaning and lubing the panoramic sunroof every 4 years/40,000 miles and replacing the HEPA filter (if equipped) every 6 years/60,000 miles is recommended.
