Mercedes is approaching the launch of its electric top model EQS on April 15. By then, the manufacturer releases small chunks of information to keep interest up.
Last was the interior design. Now they also lighten the veil regarding specifications and driving experience.
As we are still in the middle of a pandemic, it is difficult for journalists to test drive. Mercedes therefore arranged a digital test drive of the car earlier this week, where we got to “sit on” with Mercedes’ test driver.
AMG version to be launched
Naturally, we can not say much about how the car is experienced while driving, other than what he conveyed to us. As we get it explained, the car is mainly experienced as a Mercedes S-Class in driving comfort and acceleration.
So this is a car configured to provide a luxurious driving experience. Although the car is very well motorized, Mercedes has not focused on brutal acceleration as, for example, Tesla emphasizes. However, the car must have a good thrust, suitable for motorway driving.
We learn that Mercedes also has an AMG version on the way, which will be set up more sporty.
Longest range with rear-wheel drive
From technical details, we learn that the range of the car that was shown – EQS 450+, which has 107.8 kilowatt hours of available battery capacity and rear-wheel drive – gets a range of 770 kilometers.
This version has a 245 kilowatt engine with 515 newton meters on the rear wheels.
We are told that an EQS 580 will also be launched, which has four-wheel drive and a total of 385 kilowatts, with a total torque of 828 newton meters. With four-wheel drive, the car has an active distribution of power between the front and rear engines. Among other things, it will ensure that the most efficient engine for the driving situation is used.
The motors have a liquid-cooled rotor. The cooling fins on the stator are also liquid-cooled. This will ensure that the car can withstand repeated accelerations without overheating. In addition, there is temperature control of the gear oil, which will ensure that the car is also efficient in low temperatures.
The first editions of EQS to be delivered to customers get the largest battery, while they later come with versions with a slightly smaller battery of 90 kilowatt hours.
Mercedes will have a new generation of battery technology. They use nickel-cobalt-manganese chemistry, with a ratio of 8: 1: 1. They claim that the batteries should have a significantly higher energy density than the previous generation, without quantifying the improvement.
They are confident that it will work well: The battery warranty is up to 250,000 kilometers, or 10 years, whichever comes first.
High power and flat charging curve
The car can regenerate with an output of up to 290 kilowatts during braking.
EQS should also be able to charge quickly. It can be charged with power up to 200 kilowatts, which should provide a range of 300 kilometers in 15 minutes under optimal conditions. 10 to 80 percent should walk away in 31 minutes.
The test driver says that the car has a relatively flat charging curve. It does not hold 200 kilowatts throughout the charging session, but we are told that it will stay relatively high. Based on the information we have received, it appears that the average power from 10 to 80 percent will be around 145 kilowatts, which must be said to be impressive.
Mercedes has stuck to a 400 volt system, which after all is still the most common. It is probably most of academic interest to the user what voltage the system is running on. In practice, it is how long the car spends charging that is important.
The car is equipped with active temperature control on the battery, and if you enter the route in the navigation system, the car will suggest a stop and make sure that the battery temperature is optimal for fast charging before you reach the charging station.
EQS comes with one year of free access to the Ionity network, so you will be guaranteed access to this charging network.
The navigation system should have an overview of not only the available charging power at the stations, but also whether they are in use, as well as look at real-time traffic information to ensure that you get the most optimal driving route.
5.21 meters long
Like other cars in the S-Class, the EQS is not a small car. It is 5.21 meters long and has a wheelbase of 3.2 meters. The curb weight of the car in question we were allowed to “ride” in is 2405 kg. It is equipped with air suspension to provide the best possible comfort.
Such a long car can be challenging to navigate in city streets, so Mercedes has equipped it with rear-wheel steering. The rear wheels can be turned up to 4.5 degrees so that it is more maneuverable in tight environments.
It will be possible to choose a larger angle on the rear wheels, and get up to 10 degrees. This will be optional.
In addition to easier maneuvering in the city, rear-wheel steering will also contribute to better stability at high speeds.
Air as in an operating room
EQS must otherwise be equipped with a particularly effective HEPA air filter, which has 600 grams of activated carbon. It is supposed to provide air quality equivalent to the requirement for an operating room. 99.65 percent of all particles must be filtered from the air sent into the passenger compartment.
There is also no shortage of fancy features, we learn. The frameless doors on the car can be opened automatically when you approach the car. Here it is luxury that is in focus.
EQS shall have what Mercedes has to offer of advanced driver support systems, and shall be prepared for type approval for level 3 self-driving when it allows for this.
The car is built on Mercedes’ EVA platform, on which the upcoming EQE will also be built, in addition to the SUV versions of the EQA and EQE. The test driver says that these cars will have many of the same components as the EQS, such as the engines and batteries.
Then the question is what the car will cost. The only thing that is certain is that this is an exclusive car – in the sense that it is a car reserved for those who have the funds to buy a million car.
We guess that the price will not be far below the million, and that you will quickly go up to a seven-digit amount for a well-equipped variant. Of course, we can not know for sure before the car is launched on April 15. According to the test driver, the prices will come in mid-June.
