I always love comparing charging. Let's just pretend that there actually is a 175kW CCS v2 (not v1) charging network where you're going.
E-Tron is nominally 150kW to 80%, but in practice appears to be 150kW to ~60%, and under 120kW to 80%, and further slowing above that. So, say, starting a charge with 40 miles remaining as a safety buffer, and adding 140 miles, that's 20% to 90%, so probably an average of 125kW or so, due to the slowdown near the end. At around 240Wh/km WLTP, that's 520kph WLTP.
40 miles on a Model Y LR is 13%, and 180 miles is 60%. On a newly-updated 145kW V2 Supercharger, that'll be an average of, say, 135kW. Model 3 WLTP Wh/km is 140, so let's say 155 for Model Y. 870 kph WLTP. Now let's redo for Supercharger V3, with an average of, say, 155kW over that range (probably too pessimistic). 1000 kph WLTP.
And E-Tron is only a 5-seater with 40% as much cargo space as Model Y Much closer to Model 3 in interior size than Model Y (despite its bulky exterior dimensions; it's poorly packaged with a massive hood). The above charging figures for Model 3 instead of Model Y become 12% to 55%, ~140kW, 1000 kph WLTP on V2; and ~165kW, 1179 kph WLTP on V3.
And E-Tron is the fastest-charging of the "competitors" released thusfar
Www.abetterrouteplanner.com now supports other EV’s, in particular the i-pace and e-tron. It will also determine the optimal charging duration using ccs chargers, just as it does for Tesla with supercharging.
Pro tip: if somebody talks to you that they are interested in a non-Tesla EV, let them use ABBR to calculate how long their favorite road trip takes, and compare that to a long range Model 3. Take e.g. 1000km trip from Brussels to the south of France. The results are sobering.
