How many folks tow at 75 miles per hour? 55 would make more sense.


Watch it again, he accounted for 60 mph towing.


Square of the speed is the biggest factor. 60 x 60 = 3600; 55 x 55 = 3025; 3025 / 3600 =~ 14% savings, all other things being equal.

75 x 75 = 5625 ; 3025 / 5625 =~ 46% savings.

Towing at max load weight is, in my opinion, a bit of a red herring, and unwise. Doing so on any vehicle is not going to give good results, fuel economy wise, nor result in a long life. Of course, you can tow a 50,000 pound load with an inadequate vehicle--but how far, and how fast?

When I have time, I drive 49 mph (78 kph) because it happened, in the past, to be a "sweet spot" for my class C. Because of some recent changes, I may be searching for a new sweet spot--probably faster.

My "one day record" for driving was 1400 kilometers (870 miles). That was done at 55 mph in my previous class C diesel.

In the last two weeks I saw a suggested lease price of $79 per month (36 months) on a Hyundai Ionic. Perfect for a daily commute, but not much good for towing any serious load. To be fair, the initial payment is $999. That effectively raises the lease price to $107 per month. Prices are going to drop, and five year ownership costs already favor Bev's.

BYD has produced 500,000 Bev buses. Most travel 155 miles on a charge with a battery capacity is 150 kwh.

The buses range in size from 23 feet to 60 feet.

These units are by no means perfect. But the operating costs are well below diesel units.

As to recharging, if I were a campground owner, I'd be installing meters. 150 kwh would be possible on a 50 amp pedestal at 14 hours.

GM is promising many Bev and plug in models in the near future.

I'm probably too old to see a BEV RV, but ten years from now I suspect there may be lots.

The Trans Canada Highway (#1) is in the process of having charging stations installed at Petro Canada gas stations. They are approximately 120 miles apart. The locations will be using the fastest possible charging method (DC high voltage) and can recharge to 80% of capacity in 30 minutes.


You're taking his video much too literal. He's showing how the numbers work, not how we tow. Take the more realistic numbers we all tow with. The math is sound.

Do a little more research on BYD. The BYD buses are an apples to oranges comparison to Tesla cars and PUs. Again, plug in the numbers. No surprise they get 155 miles.

Interesting the approach Canada is taking. In the US it will have to be private enterprise that sees the need. No doubt the auto manufacturers are going to have to get involved in helping to finance charging stations. Small mom and pop gas stations are not going to put this stuff in without financial incentive.

Just how far can you drive in Norway. Not very far compared with the US, 1500 mile trips are very rare I'd say. I do not argue that EV aren't suitable for urban only driving. They are workable for short trips. But comparing Norwegian driving with what we do in the US is just silly. The same applies to the UK and other European countries.

Oslo to Tronheim is about 300 miles BTW, Boston to Miami is 1500 miles.

Ummm...norway sales are almost completely a political tree hugger socialist plot...the govt MANDATED EVs and heavily penalizes anyone who doesn't buy them.

Funny thing is Norway can afford this political boondoggle because...get this...they sell huge amounts of that nasty oil to fund it.

Soooo, the truth comes out.[emoticon]

Hi Campfire,

Both Petrocan and Volkswagon are private for profit companies.

The Hotel nearest me has 3 level two charging spots. They are being used by travelers from BC on occasion. That is 600 miles.

And how often do you drive Boston to Miami? Or 1500 miles? And do you drive 1500 miles without at least one overnight stop? (I sure don't).

Assuming one eats meals out (car travel) then I'd stop for both lunch and supper. If I pushed *really* hard I could do 500 miles per day.

That gives charging time at noon and supper, with overnight stop (full charge), another noon and supper, another overnight stop (full charge) and then lunch on the third day.

That would be possible right now even with the limited number of charging locations.

Batteries are not needed for a dedicated route.

I understand the London tube first ran with steam engines. Doubt that was pleasant.


Actually the first ones were horse drawn.

That’s kind of how we roll. The only time we charge is mealtimes or chihuahua breaks. We do a full charge overnight at the hotel so every morning we start with a full charge. No lost time to gas stations etc. BUT, a long day for us is not much more than 600 km. Off the road by 4 or 5. A quick swim or a little time in the exercise room, supper, kick back, rinse and repeat. Everybody travels different.

Exactly, my daughter owns a Tesla X and travels between California and Nevada for their business and 99% of the time charges it at home.

Her husband is happy as this keeps her hands off her Lambo Aventador although they now fight for the wheels on who drive the Tesla.[emoticon]

I've ordered a Cybertruck to pull my RV and if I get 150 to 200 miles between charge, I'll be happy because that my normal stop for gas, lunch and toilet breaks anyways.

So what's everyone else's problem again?[emoticon]

Yes that is the part that grinds on me. Everyone has an example why Tesla or an EV in general cannot work for them.

SO DON"T BUY IT

Nothing works for everybody in every possible situation. Be happy for those that can make it work.

Why is that so hard?
