This car might tip the scales at 2690kg, but it certainly has no lack of power. In any of its five driving modes, the EQE 53 feels wonderfully determined. The power is restricted in all modes apart from Sport Plus, where the headlining 677bhp becomes available. So configured, Mercedes-AMG claims a 0-62mph time of just 3.5sec. For comparison, the EQE’s petrol sibling, the 604bhp Mercedes-AMG GLE 63 S, requires 3.9sec.
With two electric motors and all that torque, there are explosive replies to big throttle inputs here and the four-wheel drive system places the EQE 53 SUV’s reserves to the road with stunning effect. There is plenty of feel and immediate response from the brakes too, which have been upgraded with a new electromechanical booster together with 415mm front and 378mm rear steel discs (or optional 440mm carbon-ceramic front discs).
The driver can alter the drivetrain’s energy regeneration calibration in three stages via paddles on the steering wheel, with maximum regeneration reaching up to 260kW. A digital sound symposer, called the AMG Sound Experience, can also be engaged to play a variety of different synthetic soundtracks, some of which give the impression you’re aboard a spaceship rather than a five-seat SUV.
Dial the performance back in Comfort mode and there are also very agreeable qualities to the drivetrain at urban speeds. Smooth and refined, it makes for surprisingly relaxing driving when you want it to. The overall range is a claimed 292 miles in combination with 21in wheels (and 22in wheels are optional).
