Although AMG’s existing combustion-engined GLE-based models come in both SUV and SUV-coupé bodystyles, the new electric model will be offered solely in SUV form, with a “relatively upright tailgate and angled rear window” providing “the best balance between form and load-carrying space”, insiders have told Autocar.

Dimensionally, the GT SUV 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 previously 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 nickel-manganese-cobalt battery used by existing electric 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 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.
