Tesla CyberFlop

[740GLE]

Even the old s10 tiny isuzu truck is superior to any ev truck...

Agreed but modern trucks are 80k luxury items parked at malls vs small trucks of decades ago used for you know truck things.

IMO the cyber truck is a perfect item for those that want the latest flex, but people will still buy their powerstrokes to commute 50 miles unloaded on the highway cause you know diesel towing.

The only outlier is the ford Maverick hybrid, but sadly ford wasn’t making enough money on them so they limited production and optioned the gassers to what people would buy MPG be damned.

Because otherwise it's just a hypothesis with no tangible proof to back it up

If you can provide an example I would love to read it.

It's not a hypothesis. Drive a Hybrid with a non-functioning battery and compare it's fuel mileage to the non-hybrid vehicle.

It's also just basic physics that converting mechanical energy to electricity and then back into mechanical energy (generator to electricity to motor) means some of the energy gets converted to heat.

I would like for you to explain why you think that's more efficient and provide examples as that would be out of line with everything I know and have experience with.

Mines the same. Except everyone (my Wife) forgets to ever plug it back in, so I've just made it a habit during my nightly routine of locking up the house, to plug in the car. Even if I forget one night, there's always enough for a couple days. I charge to 70% and it's no biggie

Time to set up an alarm system!!
if the EV is parked, but not plugged in, the alarm goes off until it is plugged in! LOL

Chevt volt 2.0 is more efficient over a full energy system topped up, energy in vs energy out, than a straight gasser with the same energy in just liquid form.

Running an ICE engine at its most optimal efficiency point while charging a battery/powering
a motor consistently is way more efficient than anything a straight ICE powering a CVT could convert as load demand fluctuates it moves in and out of the optimal efficiency band.

"Running an ICE engine at its most optimal efficiency point while charging a battery/powering"

Yes, and the difference can be substantial between the peak RPM and the amount of time in a normal vehicle outside of that RPM range.

The conversion from mechanical to electrical is rather efficient; yes, it loses more power than a transmission, but it's not so much of a loss that it cannot be recovered elsewhere.

Then there's braking/downhill, especially for vehicles that are towing, there's a lot of energy intentionally turned into heat or noise that could be used to charge a battery.

But, more than anything, the biggest appeal to me is the flexibility; a diesel or gas electric vehicle that had a full power port would solve a lot of problems for many different use cases. Whole house generator, generator in the field, battery capacity for solar with gen coupled backup for pure off grid, generator our RV, much better "around town" vehicle than plugging up the DPF on a modern diesel (and getting 15MPG in my F450).

Just a lot of different things it could do well, including, of course, the primary application; towing. Towing with 1-2000ft/lbs of torque on tap and not hearing a diesel scream up the hill would be very nice.

Sure. @pollenface

We know why hybrids are more efficient and it's not because they convert mechanical energy to electricity and then back to mechanical energy again.

If that was the case the manufacturers wouldn't go through the Rube Goldberg setups they have in order to mechanically link the wheels and engine.

The new CR-V Hybrid has two lock-up clutches to link the engine directly to the wheels at low and high speeds.

I don't have a hybrid to drive. I have an EV, a turbo-petrol awd SUV, a turbo-diesel 4x4 diesel and 3x 2-stroke dirtbikes

If you're unable to back up what you're saying with a reputable reference, It's a hypothesis/opinion and everyone is welcome to their own opinion. I just wanted to see if you could provide an example, because I find the subject interesting

It's also just basic physics that converting mechanical energy to electricity and then back into mechanical energy (generator to electricity to motor) means some of the energy gets converted to heat.

Absolutely agree.

I think you're confusing me with someone else again, I have not made any argument about efficiency in this thread.

So what is it that you are you asking me to back up with an example?

 

[Supervstech]

I know there have been driving tests with the prius where they drove the vehicle where the ev portion wouldnt engage, and the mpg was abysmal, in the low teens...

"Gas only vehicles also have transmissions and CVT's that let the engine run at its optimum RPM and LOAD.

These cars would get worse mileage of they did away with the mechanical transmissions and put an engine/generator in its place that powered electric motors that drove the wheels."

For long-haul trucking, I really like what Edison motors is doing - they are building semi trucks with electric drive motors, but under the hood is a CAT engine driving a generator. The benefit to this is the engine can run at it's point of maximum efficiency all the time and shut off once the batteries are charged enough.

I daily drive a Model 3 Performance and my favorite thing about EV's is NOT saving the planet. It's instant torque and regenerative braking. Edison's semi's get the best of the EV world with their design and solve the range issues associated with long-haul trucking. My M3 is still on the factory brake pads at 85000 miles (in fact, there is a TON of meat on them and the car is on its fourth set of tires - plus the previous owner of this car certainly worked it hard). Take that to a semi where instead of wasting all the energy going down a hill to heat or Jake brake, but instead put it in a battery for going up the next hill and you are miles ahead without glazed rotors.

I ran across Edison recently. I noticed no one commented on your post, probably because they had no idea what Edison Motors is.

This will be the market that makes or breaks Edison.

The above information is 100% correct.

You guys should check out Edison motors. They're a startup based in Canada run by a truck driver, they're building hybrid-electric logging vehicles, that actually seem to be pretty well done. Maybe at some point they'll start working on a smaller truck too.

I also like their philosophy, they use non-proprietary parts as much as possible, and designed the truck to be fixed on the go. They even went with flat glass windows so you could buy glass panels and make new windows / windshields for yourself.

It's neat but there is so much stuff involved in getting emissions certified, road-worthy etc.

I assume they are just used off-road?

Are these being built en masse?

No, they're still in the prototyping phase. They look promising though, and they're definitely taking production seriously.
