Warmer weather efficiancy

[MattgID3]

so i drove from south glous to telford and back today and seeing much better MPG with the spring weather, i just drove steady with no heating or cooling on, pics below show return trip data and total data. (plus a trip to the shops)

Daft question, what speed where you sitting at on duel carriage ways? I’ve done a few local runs of 50miles at 70mph, and have been returning around the 4kwh whilst using the heating +fans.

You don't get 4.9 miles per kWh sat at 70mph, not even at temps as high as 28C, looks like a 60mph run for the given 14C to me.

4.0 miles per kWh in the height of Summer at a constant 70mph and a smidge of Aircon under recirculation is as good as it gets for motorway driving.

correct i had to defrost the windows on battery and then turned off the AC, I was driving around 58-65mph with ACC behind lorries, i wanted to see what the car could do if pushed. i did stick the aircon on for a bit and did notice that cooling is much better for consumption than heating. im looking at trips in the summer to mid wales where chargers are fewer and far between so wanted to get an idea of what the car can really do. I think 350 miles is feasible in the summer on the 58KW battery driving this way.
just to add at no point did i hold any traffic up and all non motorway was at the speed limits for the roads. its all down to how quickly you need to get somewhere.

I would say anything over 240 miles would be a miracle on the 58kw battery

4.9 is not realistic to maintain even in the summer.

Well, the guy above has presented evidence.
It seems to me that some of the newest cars (software 3.2) with the smaller motor might be more efficient, I've seen a couple of people on Facebook report similarly impressive numbers. I'm hopeful I'll see 4mi/kWh on a motorway run at 70 in my car this summer now it has 3.0. Never did more 3.8mi/kWh at 70 last year but efficiency in winter is definitely ~10% improved over 2.3/2.4 (which for me were no different as far as I could tell).

It works out to a 35% increase over the official range ,if it was possible I think VW would be shouting about it from the rooftops

Tailgating a 58mph truck ("hypermiling"), its certainly possible to do 250 miles, 350 miles is pure fantasy though in a 58kWh ID3 (6 miles per kWh).

Ha ha ha ha ha I'd missed the 350miles bit.. Oh if only.. 12C here and I am still on 150miles @80% I can't say as I saw any noticeable improvement since 2.4 either.

Sounds like a challenge when the weather warms up. I was around 300 miles range on the trip to Telford and that included a cold run of around 5 degrees in the morning. I'll figure out a 350 Mile return run and see how far I get. I think it will be very close.

Excellent efficiency achieved. I think also that the average speed achieved is a very telling parameter. You might set the ACC to 60mph but unless the traffic is very light etc. Then your actual ongoing speed achieved can be a lot less plus you have regen from all the times you slow down with slower traffic etc. - also of course the benefits of being in the slipstream behind lorries etc.

A few weeks back I went for a drive around locally in the evening - was planning to go for a walk by the beach and listen to a podcast but decided it was too cold when I got there so just drove a few laps of the area instead. 20mph, quiet residential streets so very few stops, very flat, 9-10C. Heating on LO with steering wheel heater on. Over about 20-30 minutes the car averaged 6.2mi/kWh, starting and finishing in the same place. I expect it would hit 6.5-7 on a hot summer's evening in that sort of extreme scenario. Of course it's not relevant in any normal situation but illustrates what is possible.

You're lucky you didn't get stopped.. There are ID.3 Driving School cars that the owners are reporting amazing numbers against.. but as you say not real world scenarios.

My ID3 said 312miles range when I picked it up new from the showroom. Presumably it had just pootled around the dealership compounds to get that indication. Never saw more than 240 miles real range, and even then, nowhere near a 70mph road.

Took for a short drive today I'm sure that 6miles per kilowatt is more than possible when it warms up over the next couple of months.

Once you get higher than 12C ambient temp, the efficiency gains are tiny (absolutely no battery warming), assuming you didn't heat the cabin with that drive shown.

Presuming you were driving very carefully on 30/40mph roads to get that figure?

correct 30/40 mph roads, the sweet spot for economy seems to be from 30 to 58 mph, obviously aircon and heating are range killers but i find that B-mode seems to help economy too.

Does the drive mode help would assume so if driving in economy mode

I think the battery is quite a bit more efficient at 20C than 12C, notwithstanding heating. I certainly saw my best efficiency on the very hottest days last summer, despite the aircon running harder. Anecdotal obv.

I've seen my best efficiencies at 28C, but the difference between 14C and 28C was 5% at best - that did surprise me that the difference was so little. Maybe the aircon was chewing up the difference, although I always have aircon on recirc to minimise its consumption and at 7omph, tge aircon will be as efficient as it can be.

On that scorchio 28C day, I was sat at 70 on the motorway and got 4.1 miles per kWh. I can get 3.9 miles per kWh pretty much at any temp above 12C sat at 70mph.
