I'm new to the forum, but not new to the e-tron - having owned my Launch Edition 55 for around a year now.
I was one of the first deliveries of that model into the UK around early summer 2019 so didn't really find anyone else to share info with initially, and unfortunately the car hasn't been driven continuously due to extended workshop visits, other repair work and Covid-19 restrictions. However since getting out a bit more recently and comparing my economy data with other threads on this site I downloaded the data from the 'my Audi' app and started playing around in Excel to analyse the .csv file.
Basically the data set is around 500 journeys, a couple of which seem to be logged twice (with similar start times, durations and distance logged) so this might be a bug. However there's a full year of data now and quite a lot of journeys.
Most of my trips are local town traffic, stop/start and under 8 miles on average. So for certain I'm using the air-con and heating during the year for short cycles where they are using the most energy to attain their set-point. A lot of journeys are only 1-2 miles. Occasional longer journeys of 180 mi for holiday have been few and far between.
I'm going to quote the data below in miles per kilowatt hour, i.e. how far can I go with each of my precious 95kWh in the battery before recharging. NB I understand that the net available capacity is more like ~86 kWh because Audi kept some of the battery spare for deterioration over the lifetime of the battery.
So having outlined the basic details of how I'm using the car the overall average energy usage across all 500 journeys is:
1.63 mi / kWh (or 2.62 km / kWh)
That's much lower than I was hoping IMHO and extrapolates to an average range per 100% charge of just (1.63 mi * 86.5 kwH) = 140 miles based upon my driving requirements e.g. short journeys with air-con, heating, stop-start traffic etc.
I decided to dig a bit deeper into the figures to see if my consumption was getting worse over time, or affected by the ambient temperature. Generally I always recharge when I'm around 45-50% remaining and cap the charging cycle at 80% SoC so that's not a variable in my use.
Graph 1 - average speed (mph) vs average consumption (mi/kWh)
This graph shows the average speed over every journey shown against the energy consumption average for the same. I guess even though we might reach 70 mph regularly during a motorway journey the average overall is much less when including the regional roads etc. So you'll see a sizeable spread of average speed data points, and no journeys with an average speed above 43mph (2.6 mi / kWh). There is one outlier, a data point on the right where consumption was 5.5 mi / kWh during a journey where I travelled 4 mi in 18 minutes at an average speed of 12 mph. Go figure!

Graph 2 - average speed (mph) vs median monthly temperature (degC)
Now this was only a hunch, but I thought it's worth looking at the median temp for any given month for my location in the UK (Greater London) and see if energy consumption correlates with the temperature shown in orange. The green line is just a moving average of mi/kWh through the month to see if there's much of a causal link. I'm not a statistician and there's a few gaps in the data but I think it's fair to say that consumption goes up (i.e. less miles per kWh) during the coldest months, which is to be expected when some mornings have been approaching or lower than zero C and when using the heaters has been mandatory. However the hottest months don't seem to have had such a clear impact when using the AC - in fact the hottest month also seems to have been the one where I saw the outlier of 5.5 mi / kWh!

Graph 3 - a different visualisation (mi / kWh consumption stacked on top of average speed)
![333]()
I think that this shows nicely how there is much better economy when the average journey speed is higher - hence much less start/stop traffic and lost energy due to that repeating cycle.
In summary
My car's MMI currently shows an average Long Term memory over 3,000 miles of 1.8 mi / kWh, and with the data shown above this points to a fairly close approximation when viewed alongside the myAudi app exported information. I'm guessing that a car like the e-tron was designed primarily (both aesthetically and functionally) as a town car, with occasional distance/range potential when coupled with ultra rapid charging - but I would say that the overall range promise of 248 miles at 100% SoC is not realistic for that type of use. As I've said before a lot of my journeys are very short, often commencing in the morning when the interior is cold and needs heating (I do try and pre-warm when I remember!), but the start-stop nature of queuing traffic in town is the major detractor from better economy. If I look closely at the higher mi/kWh values there are a wide cluster of data points around 1.7 - 2.8 mi/kWh concerning any journeys with average speeds greater than 20 mph.
If I multiply those examples by the 86.5 kWh maximum capacity of the battery it equates to a maximum possible range (for journeys above 20 mph on average) as [147 to 242] miles. Results may vary ;-)
Is it a problem for me? No.. not currently, I can easily go days without charging the car and the monthly charging costs are between £15-20 a month for 3,000 miles a year. I've never not been able to recharge the car overnight back to 80% - so from that point of view the economy isn't important - and the car is just beautiful to drive!
PS - to be honest, I put this together to test my own understanding of the way the car was behaving but decided to throw it out for comment. Please do let me know your thoughts and/or compare with your own data!
