Dimensionally, the new model sits between the 4863mm-long EQE SUV and 5125mm-long EQS SUV. Inside, it adopts a unique design for the dashboard and displays, together with new AMG.OS software.
“SUVs have been among our most popular models for many years,” AMG CEO Michael Schiebe told Autocar. “We are responding to this by offering customers a high-performance off-roader based on the AMG.EA platform. Our new high-performance architecture follows a clear philosophy: AMG first, EV second.”
AMG is remaining tight-lipped about the battery technology. However, Autocar has been told it will introduce a different chemistry combination to offer greater efficiency and a longer range than the existing lithium-nickel-manganese-cobalt battery used by existing electric-powered AMG models.
Extensive development is also being done on heat management, especially around liquid cooling, to support much faster charging rates. For reference, today’s Mercedes-AMG EQE 53 4Matic+ uses a 90.6kWh (usable) pack that has a claimed maximum range of 321 miles and can support a charging speed of 170kW – good for a top up of 112 miles of range in just 15 minutes.
Additional new software developments and inverter technology developed in partnership with Mercedes’ High Performance Powertrain division in Brixworth are also on the way, Autocar has been told.
The new AMG SUV is underpinned by double-wishbone and multi-link suspension featuring the company’s newly introduced Active Ride Control system – a set-up also being readied for its new electric saloon.
Already incorporated on the current SL, GT and the latest evolution of the 45-year-old G-Class, Active Ride Control features hydraulic pumps for each wheel to help reduce body roll while providing constant self-levelling properties.
Without traditional roll bars connecting the two opposing wheels front and rear, it can also isolate the compression and rebound characteristics at each wheel in a bid to improve the ride over AMG’s earlier suspension developments.
Additionally, this set-up will support an automatic reduction in ride height at higher speeds for added aerodynamic efficiency.
Production of the new SUV will take place alongside the upcoming saloon at Mercedes’ Sindelfingen facility in Germany.
