GT/GTPE real world range

[chrisGT]

[*]Lastly, we are talking about a GT/GTPE here... If you wanted to get tons of range from something that does 0-60 in 25 seconds, go get a Prius. I think it's comical to see people driving their GT/GTPE's in the city like some 105 yo with a walker. There's many people who have told me I need to drive under the speed limit to get better range... NOPE, not going to happen. This is not the car to hypermile in...

I'm slightly disappointed with the range because I think that they can do better. I'm hoping for an OTA that improves long distance range.

Good point about expecting good range from a high performance car. My ex Taycan 4S which has similar performance, about the same weight and slightly smaller usable battery capacity (84kWh) could do 270 miles on Sport mode and spirited driving and almost 300 miles on Range mode. Taycan's highway range was very close to city range. So it is doable!
(For comparison I am getting 230miles at best on same route, same driving style, similar temperatures)

However I don't think that a software update can improve things much.
Maybe the increase in usable battery capacity will give us another 8 miles. But there is so much you can do with just software if the right hardware is missing.

Taycan has a 2 speed transmission on the rear axle which shifts to second gear after 35mph and that allows the motors to not run on super high speeds were they need a lot of power. Probably the motors are a little mote efficient too.

Exactly as I stated it. Range is for distance. I would expect the EPA 260 to be distance driving, not 25mph city streets. This is what I've said all along and the reason for my disappointment.

I agree with your thought that range is for distance. But, EPA range has always been a mixture of city and highway. We were never given individual city/highway estimates.

The window sticker is definitely confusing then.

It gives MPGe for city/hwy then a range. And on the range it doesn’t specify. Yes, it is more efficient in the city, but I honestly when thinking “range,” thought it was for distance driving as well. This is from my window sticker:

According to Fueleconomy.gov, the Premium AWD extended range is rated at 96 MPGe city and 84MPGe highway, 90 combined. They do not have a listing for the GT or GTPE yet.

There is definitely some weirdness to the MPGe numbers that is probably a whole other thread.

The window sticker of 88/75 I posted above is for a GTPE.

Ok - so you have the information you need to calculate highway range. We know the "average" range is 260 miles and the "average MPGe is 82. Highway MPGe is 75. So it is just a ratio. Highway range = 260miles * 75MPGE/82MPGe = ~238miles.

You were posting yours as I was typing my post. Thanks for the info!

For road tripping, you'll probably only charge to the 80% cliff and leave 10% buffer. That means you'll want to stop every 165 miles or so. If you are driving in conditions that match the EPA highway test cycle.

Yup sounds about right. ~2 to 2.5 hours between stops (depending on average speed, weather conditions, driving style, elevation changes, etc.), with an extra half hour on the first leg (if starting at 100%).

In the real world, what that means is you can get to 5+ hours (~400 miles) away from home with no additional time added vs. ICE if you plan a meal on the way (and charge while you are eating). Longer than that and you are likely added a little time for a charging stop that will take a little longer (variable with family size) than a bathroom / fuel stop in an ICE vehicle.

Ok but (usable 88/41)x100 = 214.... Sooo when it says on the sticker 41 kWh to get 100 miles then I'm confused.

That means you'll want to stop every 165 miles or so.

Agree! That's exactly what I said here.

Not so sure about that... My trip I'm doing this weekend in my Audi would take 6/6.5 hours. Plugshare is telling me it's gonna be 9 in my GTPE. I will confirm soon!

So on my trip home I managed to do about 2.5mi/kWh @77mph which is the same I noticed on my FE. No difference.

I average 3.0mi/kWh normally but I beat on it. I'm assuming I could do even better. One day I drove 140 miles mixed city and fast highway and did 2.8mi/kWh and was pretty impressed with that considering I hit 100+ a few times.

My GOM is totally screwed though. I've driven the car ~600 miles since getting back from my trip home and the GOM still assumes I'm doing 2.5mi/kWh by its calculations. It makes no sense because I can manually do the math of energy used and it matches the Trip 1/2...however the 'current trip' always reads super low. I can reset trip 1 and then 'current trip' and trip 1 will be totally different numbers at the end of my drive? Trip 1 being correct, 'current trip' reading about 0.5mi/kWh lower. Anyone else see this happening? Didn't happen with my FE.

Are you still seeing equivalent range on your GTPE as your original FE?

How far is the trip, and what stops would you normally make on that drive (food, bathrooms, fuel, etc)?

480 miles. I would stop twice for gas and food. I never eat "sit down" when traveling so it's always quick. It's all freeway driving 75/65 mph zones.

Yeah that is at least 2 charging stops, so ~80 minutes on top of the pure driving time (6.5 hours at ~75mph). Maybe consider making one of those a "sit down" meal so the time passe more quickly!

That is also assuming that chargers are available on / near your route.

You’re probably right.

But that’s a ton of math. They really need to explain this better because I guarantee that the average person seeing a “260 mile” advertised range is going to expect to be able to do at least 200 miles on a highway road trip safely.

That was definitely the number in my head (200).
