So...

Last Sunday my son (10) begged me to take him skiing. We live in West LA, 125 miles from Big Bear (which is also the top of a mountain).

I agreed. And we drove, mostly on the freeway to Snow Summit in Big Bear. 125 miles. 41% remaining when we got to the slopes.

Four hours of (slightly more exhausting for me) skiing later we were done.

Back in the car, the battery percentage had dropped to 39%. Could we get back?

SatNav said "no" and wanted to route us via an EV charger. I reckoned "yes".

The first bit of the journey was ups and downs on the mountain. My battery remaining dropped to 34%. I switched range mode on.

Given that it was mostly downhill from this point, I turned regen on to auto. (Which is terrifying, by the way, as it turned regen on to avoid us rear ending the car in front.)

At the bottom of the hill, I had

...38% remaining.

Surely this would be enough.

SatNav said "no".

My son recommended simply turning the SatNav off and winging it. Now I normally follow the principle of not paying too much attention to my son's suggestions, but in the case he was correct.

Range mode off (70mph is too limiting), we made it home with 8% remaining.

So, 252 miles on freeway and mountain roads, including a fair amount of traffic, and 8% remaining at the end. (And our Taycan was not exactly lightly loaded, given two sets of ski gear.)

How did the EPA come up with their range numbers?

Did you start your trip with a 100% SoC?

I did.

I'm thinking (on Sunday) of doing the ride again from 85%. And sticking it in Range mode the entire time, and seeing if I can get there and back on 85%...

I suspect it'd be a little too close for comfort :cool:
