Mercedes-Benz has unveiled a mid-cycle refresh of its flagship electric sedan, the EQS, with a focus on significantly boosting the vehicle's driving range. The updated EQS now offers up to 575 miles (926 km) of range on the WLTP cycle, making it the new mileage champion among luxury electric cars. The refresh also includes faster 350 kW charging, a new two-speed transmission, and a host of other high-tech upgrades.

Why it matters

As the electric vehicle market matures, automakers are increasingly competing on key metrics like driving range and charging speeds to attract luxury buyers. Mercedes' decision to prioritize range improvements for the EQS refresh underscores how critical these factors have become, especially as the EQS faces new competition from rivals like the upcoming BMW i7.

The details

The 2027 Mercedes-Benz EQS now offers a maximum range of 575 miles (926 km) on the European WLTP cycle, a significant increase from the previous model's 511-mile maximum. This is achieved through a larger 122 kWh battery pack, up from 118 kWh. The EQS also boasts an industry-leading drag coefficient of just 0.20, helping maximize efficiency. Charging speeds have been improved as well, with the ability to add up to 198 miles (320 km) of range in just 10 minutes at a 350 kW fast charger. Other upgrades include a new two-speed transmission, cloud-connected suspension damping, and an expansive 55-inch 'Hyperscreen' display.

  • The 2027 Mercedes-Benz EQS was unveiled in April 2026.
  • The updated EQS model is expected to launch later in 2026.
