Mercedes has put a lot of effort into the interior of the EQS, which combines bespoke elements with those already used in other models. As standard, it has a layout similar to that of the S-Class up front, with 12.3in and 12.8in digital displays for the instruments and infotainment system, in combination with a steering wheel that features touch-sensitive controls on its upper spokes.
Buyers can also specify the EQS with the new Hyperscreen: a one-piece curved display that stretches across the width of the dashboard, housing three digital screens: one for the dials, one for the infotainment and one for the front passenger.
It’s impressive, no doubt, but the 1410mm-wide display is prone to reflections in sunny conditions, despite the inclusion of a sensor that alters automatically its brightness. It does work with impressive speed, mind you, thanks to an eight-core processor and 24GB of memory.
It’s all controlled by the latest generation of Mercedes’ MBUX operating system, which has both touch controls and ‘Hey, Mercedes’ conversational speech input as standard. It also supports over-the-air software downloads, so owners can update various features and tap into a new subscription-based service available via the Mercedes Me app. What’s more, there’s a head-up display with augmented-reality functions for the sat-nav directions.
A high-set centre console divides the front seats, providing various oddment storage possibilities. The seats themselves are broad and magnificently comfortable, if a little short on lateral support. They can be ordered with up to 19 adjustment motors and 10 massage programs.
The rear can be configured with either a three-person bench or two chairs. Accommodation is excellent, especially for legs and shoulders. While the EQS does without a ‘frunk’, unlike some EVs, its 610 litres of boot space is 60 litres more than that offered by the S-Class, and the space extends to 1770 litres when the split-folding rear seats are collapsed.
Two EQS variants are available initially. Opening proceedings is the 2480kg EQS 450+, which has one motor that develops 329bhp and 419lb ft, affording a 0-62mph sprint time of 6.2sec. It gets a range of 485 miles from the 107.8kWh battery pack used by all models at launch, equating to efficiency of between 3.1 and 3.9 miles per kWh.
