I had a peak of 28.7MPG combined over 212 miles only about 10miles of EV use over the 212miles


that 10 miles includes 8.5 miles of FREE ENERGY! (down hill that was 25mph so we say in EV mode the whole 8.5 miles!)




that is with a v8 6.0L engine the battery only has about 10% of 1.5KWH life left so only 0.15KWh...

At perfect conversion, you get about 36 kwh in a gallon of gasoline

0.797Kwh per mile assuming 100% efficiency of gas conversion...

well be generous and say 30% as the pulley only drives the water pump has VVt etc... etc..

0.2391KWh per mile


or 4.1 miles per KWh




i think it could get 50mpg in a Prius chassis it's 1/2 the weight and 1/2 the coefficient drag

V8-hybrid in prius = 50mpg



I will be swapping out All the bulbs for LEDS pretty soon i'm sure it will help a bit.. I also thought of doing some inexpensive Aero mods as well

I like the show the math and assumptions approach, but there's zero chance a Tahoe is getting a 4.1 mile per kWh EPA rating. That's what the Model 3 gets.

The Tahoe gets similar fuel economy to half-ton sized trucks, so I would expect them to have similar EV efficiencies.

Considering the very efficient Model 3 gets ~4 miles per kWh, I expect a truck to get about half that, or 2 miles per kWh.

My leaf gets about 140mpg equivalent or 4 miles per kwh during warmer months with out even trying. Normally I get 4.5 to 4.7 miles per kwh with out the trailer.
Best case scenario a pickup gets about half the fuel economy of a non hybrid economy car.
So figure 70mpge or about 2 miles per kwh.

100% conversion never works out it's not a perpetual motion machine



32.78kwh for E10 gas



realistically you can only get 10.1kwh out of a single gallon of gas 33%(some newer engines are upwards of 40% )
10.1KWh ÷ 28.7 miles=
0.352KWh/mile


40-45.45MPG would be the actual so basically you have what amounts 3 gallons of gas equivalent , using the efficiency percentage of an ICE engine...

Just to be clear I was speculating electric economy of an electric pickup not actual gasoline burning pickups fuel economy.
Plus only getting the equivalent of 40mpg would be catastrophically bad for an electric pickup that wasn't towing something big, thats barely over 1mile per kwh.

People keep saying that it would have sold with any name, even DonkE, so why call it this, when Ford will still sell gas Mustangs that do not look like they need an intervention:

I wasn't a fan of the looks when I first saw it, but it's growing on me. I prefer the silver grille of the GT to the body color one on the other trims. Looks much better than the Model Y.

I think efficiency will be a little better than it looks just comparing range to the battery capacities they've announced. The quoted battery kwh is probably the actual full capacity of the pack with the usable capacity being 80-95% of actual. It would be silly to list a usable capacity of 99kwh when 100kwh is such a nice round number.

I can't help but see this with most new vehicles. The new American dream, perhaps?

a better question is why is everyone using the 100% conversion of gas I guess it's the same people who think solar roadways is a great product .. or can pull water out of the air into a water bottle

using 100% conversion rate is claiming it's equal to 3 gallons of gas

=300 miles but in reality it's 10 gallons of gas as noted by the CX-3 which is = to the mustang version..



also btw the part were it says "Fossil Fuel Free" is a joke it should just say powered by Fossil Fuel Coal,CNG and nuclear ( are types of fossil fuels)




so unless your generating the power from wind or solar on site to the "electric car" you are still generating emissions.. that will never be off set..


unless you live near a hydro power plant it's not fossil free or negative offset
