Whether you choose the 2730kg EQS 450 or the 2735kg EQS 580, you will find no lack of traction or performance. Both provide strong and linear acceleration, considering their considerable weight. Mercedes claims respective 0-62mph times of 6.0sec and 4.6sec, while the top speed of both is governed at 131mph.
It’s at a constant cruise where they really excel, though. The dual-motor powertrain is silent in operation. There’s no telltale whine, just an instant deployment of power. Rolling refinement is also truly exemplary, tyre noise and wind buffeting being terrifically well isolated. This is one of the most refined cars that money can buy.
It’s intuitive enough to drive too. The steering is light at urban speeds, enhancing manoeuvrability in tight spaces, then weights up nicely when you pick up the pace on the open road, providing precise turn-in, if little in the way of proper feel. The majority of the car’s weight being within its floor structure helps matters, ensuring a low centre of gravity that provides the basis for safe and predictable handling.
With the rear wheels able to turn at up to 4.5deg, the EQS SUV is far nimbler at low speeds than you might expect – even more so when fitted with the option that extends the rear’s assistance to up to 10deg. At higher speeds, meanwhile, car’s ability to provide a varying amount of drive to each individual wheel means it always has plenty of grip and purchase. The self-levelling qualities of the standard Airmatic air suspension also help to counter pitch and lean.
Less spectacular is the brake feel. As in other EQ cars, the weighting is inconsistent. There’s no doubting the stopping power, but a more reliable pedal feel would be welcome at times.
While it’s doubtful that many will take their EQS SUV off road in any serious way, it does optionally offer an Off-Road driving mode, which raises the ground clearance by 25mm and primes the 4Matic four-wheel drive system. Additionally, there are off-road graphics and images from a 360deg camera, including a so-called Transparent Bonnet view.
