I don't think that's quite said right. Constant speed usually refers to highway driving (vs city) which usually means higher speed. Yes, higher speed is bad for efficiency. But constant speed (if it's a flat road) is actually good for efficiency. It means you're never having to slow the car...

We're on a road trip to Las Vegas. Car started flaking out yesterday. Radio wouldn't work, Assistance Systems Error (no ACC), no speed limit showing, and that little yellow symbol that looks like a car next to a stop sign (??) is at the bottom. 15 minute drive across town. After I got there...

Yep. For example, when we hit a steep downhill stretch with ACC on, we can see the power meter go negative (i.e. capture power through regen) as ACC keeps the car from speeding up. We're not even touching the pedals. It would technically be a bit more efficient to just let the car coast, but...

Right, the car is using regen to slow the car down whether hitting the brake pedal (up to the point that regen max's out, beyond which friction braking adds on) or lifting off the accelerator pedal with Regen on. Just 2 different ways for the driver to do the same thing. It's a personal...

Perhaps, but the real point is that using applied slowing of ANY kind is less efficient than coasting. Friction braking recovers 0% and is thus WAY worse then regen. Regen isn't quite 100% but it's way better than 0%. While pure coasting loses no energy. The question is how much can one...

I reluctantly use the native nav part of the time on road trips in order to see the estimated arrival%, since Porsche failed to implement the AA feature that shows it. Otherwise I like AA nav much better.

The only scenario that makes sense to me that would make it more efficient to turn regen off during highway cruising is if you're driving on a mostly level highway with lots of short rolling dips. If the road is flat where you never have to slow the car down from coasting speed, it should...

I don't think I've ever had a car that did that. The volume controls have only controlled volume (UP-DOWN-MUTE). The PLAY-PAUSE-FWD-BKWD controls have always been separate from the volume controls. Perhaps they could program that button specially to first look and see whether the audio...

Agreed, the negative arrival number would be much more useful. I'd almost never see it because I'm not one that's comfortable pushing it that far, so I'm usually targeting arrival with a significant safety buffer. But there are rare times where we have a long gap with no chargers to cover...

Yep. People that got their EV start in a Tesla tend to favor kWh/100mi. But those of us coming from ICE vehicles tend to favor mi/kWh (MPK), because we're already used to mi/gal (MPG). Neither one is right or wrong, but it drives me crazy to see it the other way because I have to sit here...

As pretty much the last major automaker to get onboard, I would certainly hope they'd be able to get right what everyone else did before them. Yes, it works like it should. Cool. The fact that was even a concern is a bit concerning in itself. :cool: But yes, good that they were able to...

Our Porsche adapter doesn't work. Fortunately I was carrying my Ford adapter from our previous Mach-E on the last 2 trips. A have been meaning to try it at a local SC one more time just to confirm, before contacting Porsche for a replacement.

Unless you start the day with 80%+ like most would on a road trip day. By the time you reach your first DCFC, the car has had plenty of time to precondition the battery for the first charge. You're not making it 200 miles that first leg on a cold battery, of course, but there's still plenty...

That may very well work, but I'd only bother with all that if my DCFC options were so limited that I *had* to do it. Otherwise I'm just preheating the cabin before leaving in the morning and going like normal, letting the car precondition the battery for a distant DCFC stop that the car can...

Personally, I'd just charge up overnight and leave cold in the morning (except cabin heat). It's not worth playing games that don't work half the time anyway. As long as you have enough chargers along the way to be safe, just go with that.

Those don't seem quite right, or would be unusual. Typically both the EA and SC membership discounts are roughly 25% off. An EA station that's 60c base price would usually be ~45c with the discount. 48c would usually be ~36c with discount. SCs vary a bit more. For instance, one random one I...

You may be able to manipulate it by setting a much higher arrival % at the charger. For instance, if leaving at 80%, and want to stop at a charger that's gonna take roughly 50% to get to, you might be able to set the "arrive at charger" target to something like 30%.

I can tell you that in the Macan's case (and I would assume all EVs that have battery preconditioning capability) that while slow, the preconditioning system is strong enough to overcome the wind chill effect of 10F-20F temps flowing underneath the battery pack. My pack temp moved from 28F to...

If the car is at 80-90% SOC, my understanding is that it won't precondition the battery if you just start it, set the nav, and let it sit. I think the car is looking to be within roughly half hour range of the station before it starts preconditioning. If you started at like 40%, maybe you'd be...

Just be prepared for seriously low efficiency and range. Last road trip I did wasn't quite that cold, but close (10F) leaving a hotel in Jackpot NV early morning and driving thru ID/UT on the way home to CO. That morning leg I got 1.9 MPK for much of it (normal about 2.8 in warm temps). I set...
