Stated Range vs Real World

That seems quite high. ( althoughI suppose it depends on the size of the bit)
Can you share the details of a drive from Tessie?
That would be with M3P probably?

M3LR is better. I currently have 274 wh/mile after few shorter and two 150 miles trips on motorway at 72 on AP

Managed to grab a few days data now

In a nutshell 1 kWh every 2 and a bit miles

Seems to tie in with quite a few on here
Your standard trip meter will show the specific Wh/mile.
(If it turns out higher than others then something that affects any car can be a binding brake… you can sometimes hear noise and/or feel heat at the wheel after a trip. )
 
We're just guessing until the OP shows us some data of what the car is doing. Temp, elevation, speed, acceleration all make a difference to what you'll get.
These are from Tessie for yesterday

i can get a shot of the energy page off the touchscreen if you like?

There's no time scale on these graphs, but looks like a nice burst of acceleration from 40-70 (ish). You can also see the range drops quite a bit at (I think) the same point. Were you also going uphill at this time? Does Tessie give you a time scale?

I should have been clearer, I was talking about using the 2.7kW 13A plug charger that comes with the car. My average mileage is only around 100 miles per week so I am contemplating just using the supplied charger initially. I am getting some building work done beside my driveway later this year so would need to move a charger if I installed it now, so will (maybe) get a 7kW charger installed during/after the building work. I was just making sure that using the supplied 2.7kW charger would be feasible, at least for a few months.
I use my granny charger at work all the time admittedly sometimes I work long hours on the weekend. Yesterday I got 50 percent charge over 8 to 10hrs.

The main drain on the battery are sentry mode and the HVAC system and your right foot, HUGE drains, I've noticed. If you can manage them smartly the range can be extended quite a bit.

I can drive one way in and get fantastic range and hammer it home and deplete 30 percent of the battery on one leg of my commute.


Bjorn nyland on you tube uses the ABC acronym.



Always.
Be.
Charging,

sage advice.

Granny charger on your mileage easily manageable.
 
I'm getting 240-260 range this winter on a 2021 LR but it's at the higher end when I don't have any heating on. Last week, I did a 257 mile round trip to Manchester. Stuck at a steady 70mph on the dual carriageways/motorways. Started with 100% (336 miles) and still had 55 left when I stopped 9 miles short of home for a quick supercharge, as I needed to go out in the evening. Didn't need to heat the car inside as it was plenty warm enough.

That's remarkable. LR and P really are quite different cars.

I’m sure if you took the 2021 P version out in the same run, driven the same, on the same day it would have had about 20 left on the gage when the poster stopped. The poster didn’t have the heating on so we’re clearly aiming to maximise their efficiency, that said they would have probably made that supercharger anyway.

I doubt the SR would have made it.

Electric car range is all about ‘how’ you drive it.

I have 2020 M3P, drive it fairly conservatively, manual climate set to 21. Projected range currently showing 206 miles to a 70% charge, real world range 126 miles. Car is all short journeys though.

M3LR update as I did my first long trip of around 550 miles yesterday. First up the SC network was flawless with 3 easy stops on the way. At all times AP was set at 70mph when allowed and temp between 5 and 9oC.

First leg: Oxfordshire to Charnock Richard average 280 wh/m. Weather was dry and traffic light.

Second leg: CR to Abington average 340 wh/m. Weather was not so good with rain at times, road wet. This includes the climb over Shap.

3rd leg: Abington to Dundee average 330 wh/m. This was by far the worst leg weather wise with heavy rain and gusty winds. Saw 3 accidents at side of road where aqua planing was clearly a factor.

Final leg: Dundee to Aberdeenshire average 285 wh/m. Weather okay again and arrived with 50% battery.

Take home is that the worst I can expect is 2m for every % battery with cold and wet weather including some significant gradients at 70mph. Otherwise 240-50 miles is achievable at motorway speeds in cool conditions.
