Had my DS4 since June , it has 3000 miles on the clock. For the first 5 months I was achieving 29 miles on a 100% charge but since then it has been progressively getting lower today I got 100% with 19 miles. Is this a weather thing? Spoke to Stellantis who said they would run a diagnostic but if no fault was found they would charge me. So before I go down that route has anyone any observations?
Thanks in advance.
I’ve seen a decrease as the weather has got a bit colder.
29 miles at 100% is about what I’ve seen on the display when I first got the car about 2 months ago , it has decreased since then as its got a bit colder.
My son has the new Vauxhall Astra PHEV its the same 1.6 engine and plug in, both the Vauxhall and the DS are made by Stellantis , they are basically the same car except for how they look.
He said he’s very rarely seen over 30 miles at 100% , it’s more like mid 20’s and drops in the winter.
What I will say is the electric on my DS E Tense 225 is guzzled up if not driven wisely.
I’ve never tried to get the electric range by itself that is shown on the display as I’m still getting used to driving it.
If I’m honest if I saw 29 miles at 100% I doubt I would actually achieve the full 29 miles just on electric alone, but hey it might be possible ?
I’ll give it a try one day.
But getting back to your question, I would say yes the colder months definitely drop the range, along with other factors as well.
I’ve not dropped that low yet at 100% but it wouldn’t surprise, especially after what my son tells me with his Astra, thats basically the same under the bonnet.
Mine is down to 30km now when its cold outside.
Climatising when connected to charger dramatically decreases battery use when starting the journey.
I installed the grill covers before the weekend.
I guess that they might protect the fan from snow but also decrease cold air into the engine bay = easier for the car to keep the engine and cabin heated.
Will see during this week if it affects battery performance also.
(Ive used AI to remove registration plate, hence the covers looks bigger then they are)
There’s likely no fault with your batteries. Don’t waste your money on an investigation.
My DS7 can only do half of the battery distance during winter compared to summer.
This is just the way it is with batteries and cold.
I totally agree with @DSJay - this is the reality and it affects all electric and hybrid cars.
My colleagues Q4 55 drops something around 40% during colder months.
Cupra formentor is the same, XC60 and V60 T6 the same.
But - the covers might give a little boost, at least I hope so 
In the manual they specify that they should be removed when temp is +5c which tells me that they restrict airflow to engine significantly.

Looks like we all have or will have the same situation. Thanks all for your help. I love the car both for comfort and performance but its a shame it doesn’t have a larger battery.

Where did you get the covers?
Tried searching but found nothing. Maybe they’re not available for DS7…
They was included with my car, maybe its something for the Nordic countries?
Or else the DS7 might have the “electric curtains” that almost all new cars have.
I actually thought they were joking with me when they told me what the plastic thingys was

I have had my DS7 PHEV for 2 1/2 months now and the indicator normally shows 13 or 14 miles when fully charged, but I will say I don’t look at that number as the car odometer gives a better idea on how much I’m getting from the battery which is nearly 30 miles on average. This is with the lights on, heated seats and sitting in London traffic for at least an hour covering 6 or 7 miles in an hour then 35 ISH miles at over 50mph. My journey each way every day is 41 miles as the crow flies but can change with traffic and my general feeling towards other road users 
As mentioned above mine has decreased as the months have become a bit colder, but I’ve never seen it below 25 miles at 100%.
After a full home charge I usually see 29 at 100%.
I think when I first had the car end of September it might of been around 31 to 34 at 100% .
If I’m honest if I was seeing figures constantly below 20 a 100% I would ask the dealership to check it out.
Just wondering ?
Is the DS4 E Tense 225 comparable with the DS7 E Tense ?
Jeff has a 4x4 DS7 so would that make a difference ?
Just a thought !
If your car shows 13-14 miles battery distance, I really don’t think you can all of a sudden get 30 miles out of it.
In this weather conditions (winter, below 10 C), 13-14 miles sounds correct according to what I get.
My experience is that the estimation is rather accurate as long as you drive in a similar manner.
Do you really use Electric mode only when getting 30 miles, or do you run in Hybrid/Comfort?
I searched a little to see if I could find any good data on this.
DS 7 is a bit heavier (2000kg vs 1650kg) but also has slightly larger battery pack (13,2 kWh vs 12,4 kWh) so perhaps the end result should be similar?
Would be strange if the larger DS7 didn’t have slightly worse m/kWh.
(Compared my 2020 DS7 vs 2nd gen DS4 (2021-))
Looking at brand new cars, they have very similar battery distance (slightly depending on model trim).

So, this morning I took a picture of the dash before I set off, 18 miles indicated on the battery meter 5013 on the odometer, that’s the 1st picture. The second picture shows when the battery meter reached 0% and 0 miles, the odometer read 5042 which is 29 miles. This was with the lights on, heated seats on, wipers on and there was a spirited pull away from a junction just for good measure. The 2nd picture also shows 100% electric use. If I use comfort or hybrid on the same 40 mile journey the battery just reaches 0% about a mile before my destination. This has been more or less the same since I bought the car. If I use sports mode or drive with a bit of spirit the battery will not last as long which is to be expected. I don’t poodle around, 75 or 80 mph on the major roads, 50 mph else where as I’m not a hyper milage type of guy.

Aight, I believe you. 
Wow, it’s really remarkable how your estimation is so way off!
I’m sorry I doubted you, but it’s just like I said previously, my experience with the estimation is that it’s pretty accurate. Well, in my car at least. 
Your car looks newer than mine. What model year is that?

to be fair I started to doubt myself so I thought it best to check it out.
It’s a MY2023 with a 14.2 kW battery DS7 E-Tence 300 performance line+ apparently.

Oh, so they increased the battery from 13,2 to 14,2.
That’s really good to know when comparing mileage.
I was about to ask you what your stats tab says about the consumption after such a 29 mile journey, but I’m not sure I’m gonna manage the mile-to-km-per-kWh conversion correctly… 
so those figures are using full electric only ?
Yeah, the “Zero emission: 100%” means they didn’t use any petrol for the duration.
29 miles this time of the year is good going 
I think I’d be happy with that as an average all year.
I havent had my Ds long enough to get a good feel for fuel economy, plus I do very little mileage, but i’m definitely putting in less fuel .
My journeys are pretty much like Ground Hog Day, I do the same journey everyday to work and usually park up for the weekends .
On my last car I would normally put fuel in every Sunday to Sunday, ready for the week ahead, and would usually have the almost the same mileage on the odometer every time, but now the same amount of fuel lasts around 11 days instead of 7, with one home charge in between.
It’s not an exact science but I can see a saving and an increase in milage.
