Real world range touring 19 inch wheels

[Halodde]

By far the best efficiency I've seen over this kind of mileage. Touring, glass roof, 19" with aero inserts, mostly state roads and towns with speeds from 30-75 (for the short highway stretches), temps in the mid to upper 70's, some good size hills, used AC the entire time, mostly on ACC.

Did I forget any needed details?

Nice - you were on smooth I would guess
Highest I got so far was 4.6

Yup. And although I was aware of how efficient it was, I wasn't actively trying to do it

Amazing technology - love this car

Yeah, rolling downhill the entire trip!
Seriously, that is an admirable achievement. Congrats!

This was my screen yesterday. Trip A was the drive to work in rush hour, so I couldn't go as fast as I wanted to. But it was nice seeing the numbers.

Looking at your 'since last charge' data, you only got 2.1 miles per kWh on the other 4.2 miles you drove. What the heck did you do? Launch your way over the traffic???

I *think* trip A and B only factor in when you are moving and since last charge factors in all used energy including when you are stopped. So, maybe, the difference is due to standstill traffic on the commute?

Can someone smarter than me confirm or refute this?

(Yeah, I know. That's pretty much everybody... Figured I'd say it before you did )

But, now that I think about it, I wish I had trip A reset before my workday today. I did spend some time sitting in the car working before and after my meetings that must have lowered the 'Since last charge' down to 4.8. Wonder what trip A would have been?

Yes, you are absolutely right. I was only funnin'! Also, when I charge, I often drop one kWh before I'm out of the parking lot.

Touring with 19 inch and 2000 miles. I get 3-3.5 m/kw. Combination city highway and a lot of chauffeuring of the kids to sports.

What’s your speed on highways ? Speed makes all the difference

It’s probably mixed driving. The Air’s efficiency tanks quite a bit with a lot of around town driving. The car’s efficiency shines when cruising steady state at 65-70mph. I think you’ll see majority of people lifetimes average will be in the 3-3.5 range depending on wheels. (3.1 for me with 20s, which would equate to 3.5 if I were on 19s)

My highway speed is probably around 75. Id peg about half my driving as highway.

Something I've noted elsewhere with efficiency and perceived efficiency. These cars have a lot of horsepower and are quickly accustomed to. If you are finding it difficult to achieve the higher efficiency numbers with speed limit speed, there may be two primary factors: regen braking and acceleration.

Acceleration: I have driven "normally", if not sedately, only to find out folks following (family members in ICE, non-performance vehicles) have a really, really hard time following. The car is stupid quick even with "easy" acceleration. This is only apparent to me as a driver when driving an ICE, non-performance vehicle and transitioning back while actively thinking about the differences. You have to emulate the driving habits of a sedately driving Prius to achieve the higher efficiency numbers.

Regen Braking: My wife has gotten better with the regen braking, but she used to yo-yo without noticing and uses hard regen braking without realizing. Even now, she has to make a conscious effort to keep a steady speed without oscillations. My driving is much more aggressive by comparison, but I'm more optimal with regen braking and minimize oscillations as second nature since I like to optimize. This includes transitioning in traffic to minimize deceleration from slower cars and passing with minimal additional acceleration.

Her efficiency numbers are almost always lower than my own under similar conditions due to oscillations, harder regen braking, and traffic transitions by 5-10% when targeting a known miles per kWh. Nothing wrong with how my wife drives just to clarify. She is just an A to B kind of driver with little concern of the how, and I primarily do the driving when together further reducing her time behind the wheel.

I have serious range envy of some of your replies. My GT with 19” wheels gets a range of only 300 miles or so…the only deal killer on this wonderful vehicle as I want a car to drive highway distances. This experience is 90% in town, going slightly over the speed limit but not crazy and in Smooth mode on pancake flat Florida roads. I use A/C only about half the time and music about half the time. The range is a serious disappointment and will not allow me and my wife to have electric only vehicles. I could have lived with 400-425 miles but not happening.

The in town driving makes sense. The Air is terrible in town,heavy car start and stops...really bad for efficiency.

I see your point and I raise you “I don’t care, it’s fun even in traffic, and who cares about efficiency if you’re not going anywhere” lol

I understand the common perspective on range and efficiency. But, I think it's important to realize and recognize that a fair number of us actually use these cars as our DD including logging significant miles each day. Range/efficiency may not matter much to owners who rarely drive more than a hundred miles or so in a day. But, for those of us who do, and NEED to on a regular basis, efficiency, range, charging speed, DCFC availability and reliability are significant concerns and warrant discussion.

And, yes, I understand that I could have stayed with an ICE vehicle for range, availability of gas stations etc... So, I'm walking the fine line between desiring an EV and needing to put a lot of miles on it. Maybe not the best vehicle choice for my usage. But it was/is the best available EV for what I do daily. Obviously, I wish I could have afforded the GT for the larger battery pack. But, I'm making due with my Touring and appreciate the conversation and thoughts people have on maximizing range when needed.

I don’t disagree. There’s nothing wrong with discussing efficiency, and long trips.

Efficiency is a useless conversation to have around in-town driving though; that’s my point.

I agree with you that, for most people, myself included, the daily city-driven efficiency and range are unimportant. Where range and efficiency come into play is on my road trips. Assuming most roundtrips involve driving on highways, we need to have a "reasonable road tripping speed" to have a meaningful metric. I think that number is 70-75mph. It is not the EPA's 55 mph and not the moronic 90mph. In addition, EVs have more susceptibility to weather (cold/hot temperatures, need for heat or AC, etc.).
Range anxiety is also exaggerated by the manufacturer's claimed range (EPA based) vs actual realizable range when driving at highway speed. On top of that, there is the lack of fast charging infrastructure.

I drive long distance trips (780 miles) regularly in my two EVs. I do not have range anxiety per se. I know the route and I know the EVs. Clearly, I don't default to the EPA or the manufacturer's range ratings.

I think the entire EV industry will benefit from revised Efficiency and Range metrics. I was hoping the leaders would take the lead but they won't.
