The All-Electric Mercedes-Benz EQS Saloon
Mercedes-Benz, simply known as Mercedes, is a leading global luxury automative manufacturer based in Germany. The company is headquartered in Stuttgart and is famed for its high quality passenger vehicles, to include the Mercedes-Maybach. However, the company is also a leader in manufacturing commercial vehicles, to include the Mercedes eSprinter commercial EV and the Mercedes eVito electric van.
Mercedes-Benz EQ is the sub-brand used by the company for its portfolio of battery-electric vehicles (BEVs), plug-in hybrid electric vehicles (PHEVs) and mild hybrids. The pure electric cars are branded as EQ, while the PHEVs are branded as EQ Power. The mild hybrid vehicles are branded as EQ Boost. The BEV portfolio includes:
- The all-electric EQC SUV
- The all-electric EQV MPV
- The all-electric EQA SUV
- The all-electric EQE SUV
- The all-electric EQS saloon
- The all-electric EQB SUV
- The all-electric EQE saloon
- The all-electric EQS SUV
The all-electric Mercedes-Benz EQS saloon is part of the Mercedes-Benz EQ electric mobility family. The EQS was shown at the International Motor Show Germany in 2019, as the Mercedes-Benz Vision EQS. The EQS production model was unveiled in April 2021. Production of the electric saloon commenced in October 2021. The EQS is based on the EV platform, MEA.
The EQS saloon is available, both, as a rear-wheel drive (RWD) and a higher performance all-wheel (AWD) drive variant. All variants have the same EV battery size (108.4 kWh), with a WLTP quoted e-range up to 729 km for the entry-level EQS 450+ and 576 km for the top of the range AMG EQS 53 4MATIC+.
Of course, the real-world pure electric range will be lower, impacted by a number of factors, to include, speed! So not surprising to note the lower e-range for the higher performance EQS 53. For the EQS 450+ expect a real-world range closer to 620 km, while for the EQS 53 4MATIC+, a range of 490 km will be more realistic. In any case, the EV range offered is impressive, practical and useful for most driving needs, to include, longer distance motorway trips.
All variants offer DC charging up to 200 kW DC as standard. The EV battery can be charged up to 80% in 31 minutes. The manufacturer also offers a 3-phase 11 kW AC onboard charger as standard. However, as most homes in Ireland are limited to single-phase power supply, taking advantage of the 11 kW charging speed will only be for those with access to 3-phase EV charging at home, workplace or a public charging station.
Using a dedicated three-phase (11 kW) EV charger like myenergi zappi, the EQS electric car can be fully charged in 10 hours. Single-phase charging will take longer (15 hours and 30 minutes). We at e-zoomed recommend charging overnight at home, when the electricity tariff rates are cheaper.
The rear-wheel drive EQS 450+ delivers 0-100 km/h in 6.2 seconds (max power: 333/ torque: 568 Nm). The higher performance all-wheel drive AMG EQS 53 4MATIC+ delivers 0-100 km/h in a whopping 3.8 seconds (max power: 658/ torque: 950 Nm). The top speed of the EV is 220 km/h. Of course, the electric car also benefits from instant torque.
The EQS has a high quality interior and specifications, to include: a dual-screen infotainment system as standard, with an option for a MBUX hyperscreen (17.7 inches). The luxurious EQS electric vehicle (EV) is packed with technology, to include: active distance assist DISTRONIC, rear sensors for the lane departure assistant, active steering assist, fingerprint scanner, MBUX multimedia system, widescreen cockpit, 360° camera, memory parking assist and more.
In terms of practicality, the EQS electric car offers an impressive 610 L boot space. The roofline does impact the rear-view visibility.
Bottom-line, electric driving is good for the environment and the wallet!
PROS | CONS |
---|---|
Large EV battery and good electric range | Top of the range expensive (options not cheap either) |
200 kW DC charging and 11 kW onboard charger as standard | Exterior design may not appeal to those seeking a more traditional styling |

Electric Vehicles (EVs): Jargons
There is no doubt, in that, for those new to electric driving, the terminology can be both daunting and confusing. We have chosen a few jargons to help you get more familiar with electric vehicles (EVs)! We also recommend reading our article ‘Electric Car Jargon Buster‘ for a more comprehensive list of terms.
Glossary: Electric Vehicles (EVs) | |
---|---|
Alternating Current (AC): | What is alternating current? Though we may not be familiar with this term, we use alternating current everyday in our homes to power our appliances! Alternating current is a type of electric current, in which the direction of the flow of ‘electrons’ switches back and forth at regular intervals or cycles. When an electric car is charged at home, the type of electric current used, is alternating current. |
Direct Current (DC): | What is direct current? Direct current (DC) is a type of electric current that flows in only one direction i.e. uni-directional. DC enables the constant flow of electrons from an area of high electron density to an area of low electron density. DC is quite common in our day-to-day lives. Many of the appliances we use on a regular basis that are operated by batteries, use DC. A mobile phone, a laptop, a torch light etc. In electric cars, the onboard EV battery also uses direct current to store energy. |
Internal Combustion Engine Vehicle (ICEV): | What is an internal combustion engine car? Put simply, conventional petrol and diesel vehicles are powered by an internal combustion engine (ICE). These vehicles ‘combust’ fuel with the help of an oxidizer (typically oxygen from the air). These vehicles mostly use fossil fuels, like petrol, diesel, jet fuel etc. These vehicles are characterised by high tailpipe emissions, which pollute the local air. |
One-Pedal Driving: | What is one-pedal driving? In one-pedal driving, the EV slows down or stops, when the pedal is released. One-pedal functionality reduce the need to use the brake pedal, for speed reduction or stopping. Of course, the brake pedal is still the best way to hold a vehicle in place at a complete stop. |
Smart EV Charger: | What is a smart EV charger? A smart or ‘intelligent’ electric car charger, is a type of EV charger that enables smart functionality, to include, more control by the user, and communication between the EV charging station, the operator, the utility and the national grid. |
