Efficiency comparison, Kona vs. Tesla Model Y

The M3 isn't much better. My son avoids having it on during trips for that very reason.

 

Yeah, except in summer, it gets pretty hot here, too. You would be surprised. 90's is pretty common here, esp in the interior. Remember BC is the hottest place in Canada, both summer and in winter.

Yesterday I was at our lake cabin. It was 32C (90 F) there. Lytton (just 25 miles from there) was 34 C and is tied with Osoyoos BC as the hottest place in the country. And we are not into July and August yet, which are the hottest months (temps are into the high 30s and sometimes hit low 40s (>100F). Much of the BC interior here is quite hot all summer (long days). So, yeah, we couldn't live without A/C here either.

 

Your results are about the same for our Model Y. This is actual efficiency of our Model Y since it was new. Your Kona consumption is higher than ours. We are getting just under 5 miles/kwh regularly. We always use the air conditioning because of noise.

If you want to track your Model Y's efficiency, I would suggest signing up with Teslafi.com. It collects all data (from the car) on your drives, charges, trips and efficiency. Here is an example chart of efficiency vs Temp from my data. This is not a free site. It is amazing that I can collect this data on my car. There is a trial period if your interested.

 

Weather in Vancouver itself is very local. Official temps are taken at the airport which is right on the ocean, very misleading. A few miles inland it is much warmer. But yeah, interior is downright hot in the summer. And when we get an outflow (summer high pressure system), the canyons are esp hot, like Harrison Lake (where our cabin is) and the Fraser Canyon (Lytton, Kamloops). But we also get mild winters, don't get a lot of below freezing temps. And not a lot of snow, just a few flakes and dusting a couple times this year. We laugh, when we see southern places like Texas, and even northern Florida get hit sometimes in the winter, way worse than here.

 

Did not realize there are places in Canada that gets that hot, hot here in Sudbury is 35C.

Guessing when it is past 90F or 40C any car with air conditioning will have hard time ( both ICE and EV ) as my last Ford Mustang GT took about 15 minutes to cool down car in middle of the day in summer

Range might be higher on other cars with bigger batteries, but honestly, it's going to be hard to beat the Kona for mi/kwh. Even the new Ioniq 5 won't be able to touch it, especially the dual-motor version.

 

Which Model Y do you have? And do you believe the EPA?

 

Ya, I'm kind of disappointed about how the latest generation of cars with bigger batteries are pissing away efficiency gains for AWD and larger tires. Style over substance.

 

Nothing new about that. After the Prius demonstrated that hybrid technology could yield 50 MPG, a lot of manufacturers used it to add more power with minimal efficiency gain. Oh, and hybrid badging.

But if tires, features and AWD are what it takes to get people out of their ICE SUVs and into an EV, let's not fight the marketplace. Geeks and techies may lead the revolution but we aren't going to win it alone.

 

That was a big minus for me with the Mach-E. Most trim lines have a huge uncovered non-opening glass roof that gets too hot to touch. I would have to get an aftermarket cover if I bought one.

Tesla in general is unusually trusting of technology and its customers. Kind of like Android vs. iPhone.

Kona engineering doesn't seem to be that trusting of, or even interested in, their customers. (I speak as one who has done for my Kona repeatedly draining its 12v battery what Darnella Frazier did for George Floyd, only to have a Kona corporate tech note that my carefully recorded "graph(s) provided by customer are normal operation." But I digress.)

 

So does the braking feel funny? Or does it quickly discharge enough to resume regen?
