MERCEDES EQS 580 4MATIC RANGE TEST (highway and city)

I’m going to test the range on the highway first. There is also a little bit of sporty driving on country roads with the EQS. The purpose of this part of the test is to find out the minimum range of this car by testing it at higher average speeds.

At the beginning of this part of the test, the battery is at 94%. I did the test in January and it was between 7 and 10.5 degrees. It also rained a lot this day. The first part of the test is a 117 km ride, purely on the highway, driving at 120 km/h from Brussels to the Ardennes. The battery is down to 65% and the average consumption is 25.9 kWh.

I will base my estimated range on consumption and net battery capacity. The total range based on this consumption is 416 km. I now leave the highway for some sporty driving on country roads in the Ardennes. This stretch was 62 km. After this section, the total average consumption is 25.6 kwh. The range has now increased to 421 km. Now we drive all the way back along the highway from the ardennes to Brussels. Let’s look at the end result.

The battery dropped to 26% and the total length of the ride was 288 km. Average consumption was 24.8 kwh so total highway range is 435 km.

The Mercedes EQS 580 is equipped with CCS (combined charging system). With this system, the Mercedes EQS 580 can be charged with both AC and DC. For this test, I am charging the car at a DC Fast Charger. The Mercedes EQS 580 can fast charge at up to 200 kW. Mercedes says it takes 31 minutes to charge the battery from 10 to 80% on a fast charger.

At the beginning of the test, the battery is at 12%. It’s 5 degrees outside. The car indicated it would take about 57 minutes. To fully charge the battery. I will do a 30-minute load test.

After 10 minutes, we charge at a charging speed of about 123 kW. The battery increased to 29% and we gained about 92 km on the range indicator.

After 20 minutes, I noticed that we were charging at 162 kw. I gained another 104 km of range and the battery is now at 50%.

After 30 minutes, the battery is at 71%. The charge rate dropped to 125 kw. The range stands at 368 km, so we gained 305 km, about 100 km every 10 minutes.

I haven’t done an AC charging test with this car, but let’s look at some theoretical information. The charging speed of the on-board charger is 11 kw, but optionally you can increase it to 22 kW. It charges from 10% to 100% in 10 hours with the 11 kW on-board charger, or in 5 hours with a 22 kW on-board charger

Now let’s test the range at lower average speeds in the city. I wanted to know the maximum range of this car. Let’s take a look at my results. I took this test on a different day than the highway test. This day the weather was nicer, so no rain, but a lot colder. The temperature during this part of the test was between 4 and 6.5 degrees.

At the beginning of this part of the test, the battery is at 65%. So the first stretch of 24 km was pure city driving in Brussels. The battery is at 59% and the average consumption was 26.3 kWh, which is quite high. The range based on this consumption is 410 km. This is mainly due to the many traffic lights and busier traffic resulting in a lot of stop-and-go driving. During this part it was also the coldest, between 4 and 4.5 degrees.

After that, I was still in an urban area, but with more opportunity for continuous driving. I drained the battery to 39%. As you can see, over a 127 km trip, the consumption dropped significantly and my final consumption was 21.4 kwh. This results in a range of 504 km in the city.

As a conclusion, I can say that the range of the Mercedes EQS 580 is somewhere between 435 km and 504 km, based on similar driving conditions and measured in somewhat colder temperatures between 4 and 10.5 degrees. In much colder temperatures, the range is likely to be less. In the summer, you probably have more range.

Weighing 2,585 kg, it is certainly not a light car. I think in situations with a lot of stopping and driving, this weight starts to be a challenge to get really good results, especially in cold temperatures.

On the other hand, This car has the best air resistance coefficient of any production car. During my highway test, however, it rained a lot. I think all that rain on the car also had an impact on the aerodynamic performance of the car.

All in all, I think this car performed very well in the action radius test. Compared to some other recent cars I have tested, this range is of another higher level.

As for fast charging, we did not reach the maximum charging speed of 200 kW, maybe due to the colder temperatures or maybe there was a problem with the fast charger, I don’t know. 200 kW fast charging is fast, but not the best in that class. That said, gaining about 100 km of range for every 10 minutes of charging is not at all bad for day-to-day driving.

While I have not tested AC charging, I would like to point out that the option to get a built-in 22 kW on-board charger is a really interesting option and also one that I would definitely choose for this car. Most of the cars I test only have the option of an 11 kW on-board charger. In an area like Brussels, I see quite a few AC charging poles have a rate of 22 kW, so having a car that can also charge AC at a rate of 22 kW is also interesting.
