It's been about 3 weeks since I got my e-tron S. I was getting around 175 miles range at 80% charged. Lately, it's been varying between 162 to 169 miles at 80% charged. I'm assuming it's normal. Just curious.

The range estimator (which we call the "guess-o-meter" or GoM) takes your recent driving and electric consumption into account when presenting the estimate. So if you are a "spirited" driver and/or often drive at high speeds that result in higher consumption, then the GoM will predict less range for a given SoC (state of charge). This fluctuates all the time. For example, if you take the car out in winter without using a departure timer with cabin preconditioning, you'll burn a ton of energy on the initial heating of the cabin, and if it's a relatively short trip, your average energy use may be something like 1.8 mi/kWh. This will reflect in the GoM estimated range, and at 80% it might only say you have 120 miles of range.

In short, it's entirely normal for the range estimate to fluctuate even if you always charge to 80%.

As an aside, if you use the Audi in-dash nav to route to a destination, it will take the speed limits and topography (elevation changes) into account and the GoM will adjust accordingly. It can be interesting to have the GoM say something like 105 miles remaining, only to punch in a destination into the nav and have it jump to 125 miles or something, because part of the journey is downhill.

As a datapoint, my 2019 e-tron Prestige, with the battery buffer update, shows somewhere between 160 and 180 miles at 80% SoC.

@skaven81 Thanks so much for the detailed explanation.

my 2019 Prestige with 21in wheels, 35k miles, and all the SW updates gets between 170 and 180 miles at 80%, 220 miles at 100%. Im I’m CA where temps have been in the high 90s lately.

I am a spirited driver.. My 2020 Edition One w/21in wheels gets btw/158-180 @80%, and 205 @100%

I think its far more better to just watch your miles/kWh readout. Short term history vs long term history is interesting, and tells you much more.
I'd also wish that Audi would give us an actual estimate of kWh remaining in the battery rather than a % of charge. Seems like a hold-over from the days of ICE fuel tank levels. Apparently the car makers think we're too stupid to understand how to deal with a number of gallons or kWh remaining.

Anyways, I did a full reset of history when I got this car, long term average is 2.6 mi/kWh over about 1k miles.

My short term averages around 2.7mi/kWh. I haven't checked the long term yet. I'll reset them and compare the values after a thousand mile.

My 22 MY is getting about 170-180 miles at 80%. I'm near Sacramento where it gets hot in the summer so the AC is usually blasting. The car isn't driven up hills a lot, and it is driven on surface streets more than the freeway.

I recently drove to the Bay Area and back. On the return trip, when I got home the mileage was within about 4 miles of where it was supposed to be based on what it said when I started the trip. That said, I am pretty happy with the actual range that I am getting thus far.

i agree, better to compare this vs what kind of charge you are getting at 80%. my lifetime average is 2.3 mi/kwh over 42,000 miles now.

i am a spirited driver and don't bother with hypermiling. pretty much i drive it like a normal car. i never put it on efficiency or eco. it's almost always in Dynamic and Sport.

I'd agree it would be nice to have kWh remaining. Could be a legal thing with battery degradation and comparing vehicles at full charge, why my full, 100% e-tron only shows 79kWh and another full 100% charged e-tron shows 86kWh remaining, not to mention the confusion the battery buffers might cause some people. Percentage and guess-o-meter range based on current driving habits is a pretty safe way and lowest common denominator way to display remaining battery life.
