Mercedes hasn’t shied away from declaring its electrification plans, as it intends to offer an electric vehicle in every segment from 2025 and transition to an electric-only brand by the end of the decade. To usher in its new zero-emissions era, Mercedes is launching what the German brand believes is the ultimate luxury electric car: the completely new, designed-from-the-ground-up EQS. 

While more variants are expected to arrive in the near future, so far only two versions are available: the ‘entry-level’ EQS 450+ gets a single 324bhp electric motor powering the rear wheels only, while the currently top-of-the-range EQS 580 4MATIC features two electric motors (one on each axle) and produces 516bhp combined. It’s not quite Tesla Model S Plaid quick, as the over 2.4-tonne luxury electric limousine takes 6.2 seconds to reach 62mph from a standstill – or 4.3 seconds if you go for the 2.6-tonne all-wheel-drive version – but the considerable torque of even the 450+ model is enough to surprise you. But if you still don’t think the EQS is fast enough, fear not, because Mercedes' AMG performance division has produced a more powerful version with up to 751bhp.

What’s also undeniably impressive is the EQS’ range, which is thanks to both an incredibly low drag coefficient of just 0.20 – claimed to be the lowest of any production car to date – and a gigantic 107.8kWh battery. The result is a Tesla-troubling 453-mile range for the rear-drive 450+ model, and around 420 miles for the 580 4MATIC model. For reference, the latest Tesla Model S Long Range is capable of just over 400 miles, while only top-spec Porsche Taycan variants can crack 300 miles on a charge.

But it’s not just about headline-grabbing figures – what helps the EQS stand out from the rest, including all other modern Mercedes, is its interior. The centrepiece is the 1.41-metre-wide 'Hyperscreen', which is standard on the 580 4MATIC, but is a nearly £8,000 option on other models like the 450+. Under a huge single piece of curved glass are three separate screens: a 12.3-inch digital driver’s display, another 12.3-inch unit for the front-seat passenger and a 17.7-inch central infotainment screen. It’s exceptional to use, allowing you to operate everything from media and phone connectivity, to seating configurations and driver assistance systems.

While somewhat overwhelming at first, the system is surprisingly intuitive to interact with. The home button brings you back to the main map interface, with an easy-to-access favourites bar bringing up your most-used features. And there's no need to worry about getting distracted by the Hyperscreen while on the move, as versions of the EQS fitted with the three-screen system also feature a camera that monitors your attentiveness, so the car will display a warning if it thinks you’re not focused enough on the road or need to take a break.

As you’d expect from Mercedes' electric flagship – and its own zero-emissions alternative to the S-Class – the interior features the finest materials money can buy covering every surface you see and touch, and even some you don’t. The cabin is solidly built, and while there's a familiarity to the switchgear, even minute details like those have been upgraded to some degree from what's in Mercedes’ traditionally petrol-powered flagship.

There’s no 'frunk' compartment in the EQS like you get in a Tesla Model S, Porsche Taycan or Audi e-tron GT, but you still get a whopping 610 litres of boot space and a hatchback tailgate that makes loading the rear of the Mercedes far easier than its rivals. Plus, if you lower the rear seats, the space on offer expands to 1,770 litres.

Overall, the space available in the EQS is very generous, which is what you’d expect from a car that's not only trying to exceed the expectations of S-Class owners, but also one that's 5.22 metres long and 1.93 metres wide. The EQS doesn’t offer S-Class levels of rear seat room, though – this is a result of the car’s sleek shape and low roofline. But there's just enough headroom for a six-foot-tall adult to sit comfortably, and legroom is no problem whatsoever. There’s loads of space for your feet, too, thanks to the almost completely flat floor.

To help with manoeuvring the EQS, rear-axle steering is standard. A 4.5-degree setup is standard, but our car came with the optional 10-degree setup – the result of which is a turning circle only 40cm larger than that of the far smaller Renault ZOE electric city car. After taking the time to get used to it, the rear-axle steering did make the car feel incredibly agile and surprisingly nimble, with the EQS’ light steering further emphasising its sense of agility.

The EQS’ air suspension on the other hand, isn’t perfect. Ride comfort is very good 90% of the time and overall this is a very comfortable car, with only deep potholes capable of upsetting its composure. But it also doesn’t provide the cloud-like softness some may want.

Still, the EQS offers unrivalled refinement, and is near-silent at lower speeds, with only a tiny amount of wind noise around the A-pillars manifesting itself once you approach motorway speeds. All of which makes for an incredibly pleasant driving experience, just not the most engaging.

Much like Mercedes' other electric offerings, such as the EQA and EQC, there are various levels of regenerative braking to choose from. As well as what are effectively ‘on’ and ‘off’ settings, the EQS also features ‘intelligent recuperation’, which uses the car's various cameras and computers to decide when to feed power back into the battery. While not fool-proof, it works well in everyday driving situations, with the car slowing for roundabouts and matching the speed of the vehicle in front. The system can even bring the car to a complete stop.

We remained in this setting for almost the entirety of our time with the EQS, and barely touched the conventional brakes in normal use. Given that Mercedes still hasn’t mastered natural brake-pedal feel in its big EVs, this is something of a blessing in disguise.

A 90kWh battery will be available later, but at launch in the UK the 107.8kWh unit is the only option. Charging at home from a wallbox should take around 10-and-a-half hours for either model (provided you have three-phase power to make the most of the 11kW on-board charging capability), but the EQS is also capable of recharging at up to 200kW from a fast enough public ultra-rapid charger. At that speed, it'll take just 31 minutes to replenish from 10 to 80% capacity.

The EQS 450+ is the only variant on sale in the UK at the moment, with five trim levels to choose from: AMG Line, AMG Line Premium, AMG Line Premium Plus, Luxury and Exclusive Luxury. Prices start from £99,995, but that's hardly a surprise given the amount of technology on board, the battery size and the level of engineering that has gone into Mercedes' electric flagship. The EQS' price tag is also very close to the high-spec versions of rivals from Tesla, Porsche and Audi – with kit like matrix lights, 20-inch wheels and a panoramic roof included on even the entry-level AMG Line model.

Overall, the Mercedes EQS is ideal for those who value comfort, luxury and refinement above all else, with its huge range and wealth of technology placing it well above its rivals in certain respects. The Porsche Taycan may be a better car to drive, and a Tesla Model S boasts better charging capability, but neither can match the EQS’ sublime cabin and spacious rear seats.
