Cold-weather performance edit

An explanation is order about why I deleted this fragment: Compared to similar battery electric vehicles, the Audi e-tron has a poor energy effiency during normal driving in normal climate conditions. Due to the poor efficiency during normal driving, the *relative* range decrease during winter (or motorway) driving small, compared to similar cars. However the overall efficiency is still poor compared to similar cars.

1. As far as I understand, it's not that the winter range drop is small *because* efficiency is already bad during non-winter driving. If anything, it's that efficiency might be bad during non-winter driving because the car was built with winter in mind: with extensive liquid cooling/heating system for the battery to keep it at practically constant temperature. (Tesla's liquid cooling is nothing like this because - correct me if I'm wrong - it allows both 0 °C and 55 °C while the e-tron is practically constant temperature at 23-35 °C)

The I-Pace also has such a system (the EQC seems to have one too but I cannot find hard numbers about its temperature range). The I-Pace's and the e-tron's results[1] are within 3% when adjusted (linearly scaled) for different frontal areas. For the e-tron and the Mercedes EQC there is about 6% difference when adjusted for different frontal areas[2], but the reviewer noted the EQC was helped by tailwind. So, the e-tron's efficiency is just a very little bit worse than in technologically similar battery electric vehicles.

I'm not disagreeing that efficiency is poor in *all* these cars, but partially it's the price of using a constant-temperature battery. You get worse efficiency in summer temperatures, but the range is much more dependable in the winter.

The deleted fragment kind of twisted it, as if good winter performance was an unintended side effect of poor engineering.

All these cars also suffer from poorer aerodynamics than Teslas.

2. Touching the subject of motorway vs non-motorway speed: maybe motor inefficiency at lower speed could indeed cause lower range drop on motorways (but I did not try to check that!)

3. Both relative (%) and absolute (miles/km) range decrease are small - not just the relative range decrease. Don't really know why stress the word "relative" here.

Images proposal edit

I'm suggesting a proposal to replace the infobox photo and the photos of the Sportback version with these I taken recently. The I believe the photo to be use for the infobox would be an improvement as it has a better angle which shows more details of the car and it isn't blurry or shaky. Although more busier background, the former factors I think outweighs that. The Sportback has the same principals although is slightly more reflective as it in a showroom as well as a rear image of the Sportback. I also proposed a alternative, less reflective rear image of the Sportback if people doesn't prefer the showroom one. Thoughts? --Vauxford (talk) 21:21, 9 November 2020 (UTC)Reply

Proposed edit

  • I think your proposed infobox photo is an improvement. Better angle, better background, and a bit less in the way of reflections.
  • The existing rear Sportback image is appalling and nearly anything would be an improvement, but the second one works better despite the power filler nozzle being attached, as it shows the roofline better and that's where the difference is from the standard car.
  • I'd be inclined to remove the front view of the Sportback entirely. The existing image doesn't show the rear roofline at all, and on yours it gets somewhat washed out in the glare. Barring removal of the image, yours would be preferable. --Sable232 (talk) 23:12, 9 November 2020 (UTC)Reply
 
The same car as in the current photo, but less shaky
What about this one? It is the same car, but a far less shaky photo… Best regards, --Johannes (Talk) (Contribs) (Articles) 23:30, 9 November 2020 (UTC)Reply
I like Vauxford's front a bit better but it's close. On the rest of them I agree with Sable232. Toasted Meter (talk) 23:43, 9 November 2020 (UTC)Reply
I'm gonna keep the white Sportback one on there but will replace the rear image. There is a difference between the normal and Sportback one with different front end exterior. --Vauxford (talk) 07:37, 10 November 2020 (UTC)Reply

Technical specs regarding power figures and battery capacity wrong edit

Audi's website, configurator and various other sites have different figures. Whole page littered with old e-tron specifications some of which aren't even true to that model.
