Range anxiety on EQS450 (updated with road trip results)
Hi All,
I just acquired a 23 EQS450 RWD. Enjoyed every moment so far until I looked at the energy consumption data.
As shown in the screenshot, over the last couple of days, I have gotten only 2mi per kWh in stop and go city traffic. This is quite concerning as I will be taking my first long trip with the EQS soon, and the 107kwh battery will only last 214miles based on the consumption data so far.
Is such high energy consumption rate normal for EQS driving in the city? I live in a relative warm area and the average daytime temperature is in the 50-60F range.

Reason: update
You should get much better than that, unless something is wrong with your car. I have had my 450+ for over a year and have just over 16k miles with an average of 3.0 mpkWh. This includes winter driving which does reduce range for the heater. I have found that once you are rolling the range projection is pretty accurate, changing due to speed and conditions. Depending on the distance of your trip, just plan a stop within a comfortable range. You don't list your location, but in my area most of the EA chargers are in WalMart parking lots, which is very convenient for restroom breaks while charging.
Yes this is very normal for an EQS. If you drive 13 miles a day in stop and go traffic to your destination you will probably only cover 200+ miles.
I strongly suggest you try to complete your “long trip” all at once, that way the massive energy consumption at the start of the journey doesn’t happen every 13 miles.
Unless… you are thinking that your “AVERAGE” consumption will not change if you drive more than 13miles…
Unless… you are thinking the massive energy consumption is going to continue the entire trip…
Nah…

Hmm. Are we saying the car is actually more efficient on the freeway vs. city traffic? I'm quite surprised because my previous EVs are the opposite. Will let you guys know once I take my first road trip.

No, it's not freeway vs city.
It's short trip vs long trip. Every time you start a trip, it uses a lot energy to bring everything up to temperature.
So in your example, it uses much less energy for one 104 miles trip vs 8 x 13 miles trips.
Do you pre-condition the car before the trips while plugged in?
Coming back from the golf course, 22.5 miles, in city traffic and some 75mph highway driving, I am regualrly getting 4.1-4.5 mpkWh on my 450+. And on short trips to the driving range 2 miles from my house I always get above 3.5 mpkWh. Something is wrong with the OP's car, IMHO, unless he is accelerating rapidly from each stoplight or driving in very cold temps.

Always in comfort mode, with AC set to 72. I use normal regen most of the time, but switch to strong regen when I hit slow traffic. I'm not a leadfoot, but I drive normally. Can't understand why the OP is getting such poor numbers.
On a recent trip to Waco from San Antonio and back, in comfort mode, normal regen, with AC going and two passengers with luggage, I got 3.3 mpkWh at 75-80 mph on the interstate. I was in cruise control most of the time. I was actually disappointed with those numbers, but temps were cool for Texas, in the 50's. I expect to get better numbers this summer.
Just had a thought......how long have you had it, and have you charged yet? If only a few days, I wonder if someone test drove it prior to you and did 0-60 pulls to assess the acceleration? That would make the SOC predict much lower numbers. Go on some 20-30 miles drives with your normal driving style and charge it up. It may change.

Make sense. I had it for less than a week. Today's number is way better than the last one.

I agree with you. Why is the OP getting a very poor range? It doesn’t make sense. In city driving with outside temperatures in the 30s in my EQS 580, I get about 315 miles. If temperatures are in the 40s the range jumps to near 340, and to 360 with temperatures in the 50s. If the temperatures are in the 70s, 80s, or even the 90s, the range shoots up to at least 425 miles. Something must be wrong with the OP’s car.
On highway driving, I try to limit the speed to 65-70 mph and the range is lower than city driving but not too much lower.
Sorry to hear about the poor consumption OP, I would had suspected the A/C but then you mentioned the temperature the vehicle is in so the A/C wouldn't be on anyways. What is recuperation set to?

At 50 degrees Fahrenheit one would need considerable energy for heating, while on the go but specifically for the first mile. AC would also consume energy if cooling is needed but it takes less energy than heating, specifically on an EQS without any heat pump.

So is the average consumption posted for the trip or over a past group of trips?

Oh ya trueee I forgot about the opposite side never occurred to me that if OP didn't need A/C OP might need heat instead, that explains it thanks for your comment.

I’m embarrassed to ask this question but what exactly does it mean to precondition the car while driving to the next fast charger? How is this done?
I’m going to attempt to summarize the key points in this thread:
1) The number one factor is outside temperature. If it’s frigid outside, the range will decrease as the temperatures drop from the 50s, to the 40s, 30s, 20s, teens, single digits, and so on. The opposite is true if outside temperatures rise to the 70s, 80s, and even the 90s (unless you set inside temperature to very low levels). I hate cold, so I set the AC to 76 or higher when it’s hot outside. I find that the range is hardly affected. When it’s very cold set the climate control to ECO+.
2) Speed. If you drive above 65 and especially above 70, the range will dramatically decrease.
3) Wind direction and velocity. A strong head wind or crosswind will decrease the range.
I think that’s it. If I left out something else important, please chime in. I bet that those of you complaining about get very low range are not following the above guidelines.
I have to agree that cold temperatures have a huge affect on mileage on the EQS, both the sedan and the SUV. I live on the Texas Gulf Coast and many winters we have daytime temperatures in the 70s where my mileage is great. When the temperatures drop into the 60s, 50s, 40s and 30s the mileage drops significantly. With a 90% charge, 580 SUV, a difference in mileage between 280 miles and 207 miles recorded one time this last winter

From your screen shots, your drive less but stop more. You’re basically sit on the car more than you’re driving it.(red light). That makes your consumption looks so bad. Next time when you drive, look at your consumption and you will see it goes up fast when your stop. But when distance increases, it averages out.

We have 2900 miles on our 580 and we are at 2.8mpkWh on the trip data. Our trips average 15-35 miles per hour. We too started out around 2.1 mpkwh. I don’t know why, but it seems things improve after 1000 miles. In the car under “EQ” it lists average watt hours per mile for trips. It’s really hard to get below 300. We are generally averaging 330-350 watt hours per mile. Based on the usable battery capacity of 107.8kwh, that yields about 310 miles total from a 100% SOC. We are driving in warm weather, flat land, comfort mode, with A/C set to 72. We don’t preconditioning the interior either.

I gather that preconditioning is making the interior comfortable (either warmer or cooler depending on outside temperature, sun angle, etc.) before one enters the car, correct? For a while, I was under the impression that it was something that would increase the range but it’s the opposite.

Glad to hear it improved I guess there is learning period for batteries, although not a break-in like the traditional ICE but a learn in period. You are more familiar with the vehicle now, the vehicle is more familiar with you so both are happy, the vehicle knows what is the best behaviour and you know what is the best for the vehicle.
I always thought break-in vehicles in traditional ICE was more than just running in the engine and seating the pistons, it was also indirectly to give the new owner sufficient time to really learn about their vehicle, its capabilities, features and what not before utilizing the vehicle's full potential (end of the break-in period) and WOT.
