Quick synopsis of this 5min. video: Liquid fuel is far more efficient than batteries. It's not even close.
And I was politely asking what fuels these EV’s? Aren’t EV’s supposed to save the planet?
Good post. The electric cars’ time just isn’t right now. The government forcing them on us is the problem.
Our electricy in the USA comes from Coal, Gas, combined (coal+gas) and nuclear.
The industry has about a 45% efficiency.
As a reminder, gasoline (ICE) is 20% efficient and that’s NOT counting the energy to drill, pump, refined, and transport it to the pump. So we are looking at probably 15% max efficiency, versus a 45% efficient source, combined with a 80% efficient motive.
But WHO CARES?
I want 0-60 in 2.9 seconds! I can get it with electric for < 100K. In ICE it costs 1M$
I argued with luddites here who said electric cars were golf carts.
Yeah, well, the golf cart just passed your Lamborghini. Except the golf cart has 4 doors and you have to pour yourself into a Lambo.
I’m saving lightening bugs in a jar. I can use those if I can locate a cable to connect them to my RV bike. Somebody told me to use the Apple USB Type-C to Lightning Cable, but that didn’t work. Just squashed their little butts.
To do a fair efficiency comparison you have to include the efficiency of the coal fired electric generator to charge the batteries, the transmission losses, the charging and discharging losses, etc.
and there it is...
And the average EV is an ecological disaster. To manufacture each EV battery, you must process 25,000 pounds of brine for the lithium 30,000 pounds of ore for the cobalt 5,000 pounds of ore for the nickel, 25,000 pounds of ore for copper Digging up 500,000 pounds of the earth’s crust For just - one - battery.
And the efficiency of producing the raw materials? Not saying EVs aren’t the future (they have been the future for over 100 year). But the production and disposal of them seem to cancel out any benefits of traditional petroleum based system. My 30 year old Honda gets 30 per gallon. Will anyone ever be able to say they have a 30 year old battery powered cars. Physics is a bitch
“If you do that, the ICE is actually more efficient.”
What happens if you’re really fair about efficiency, and include the drilling, refining, transportation etc. for hydrocarbon fuels?
The killer problem, of course, is that there isn’t enough electricity available, and shutting down coal-fired (and other) plants is just making it worse. Plus, wind and solar power are nowhere near 24/7 available.
It’s like the old joke about Brazil. They say it is the country of the future.... and always will be.
Yeah, it’s the Model 3 performance that can do 0-60 in 2.9, which is the bottom model Tesla. I would say a corvette is is not the bottom chevy model.
The Tesla model S plaid is the fastest 0-60 ever tested (1.9 something) by most independent testers (like motor trend), and it’s a 4 door luxury car. I think that was back in 2023, and “production” is defined as > 100K units sold, which leaves out the “supercars”.
Tesla is coming out with a roadster that is aiming at UNDER 1.0 seconds 0-60. I expect that car though to come in at OVER 100K$. Perhaps 150K$.
BTW, my daily drive is a Roush Mustang GT. I have a CyberTruck on order (no, i turned down founder’s edition, as I don’t pay extra for badges, only performance)
ETA is probably EOY 2024. We also have a Ford F150 Super as a workhorse, it’s getting long of tooth, and will go. I just had to repair the electronics in the transmission. 100$ sensor of which the dealership and most trans shops whould have changed the transmission for (believe it or not it’s true) they wanted 5K rebuilt or 8K new.
The F150 will always have mountains of aftermarket parts available. My job relies heavily on the sale of EV chips, and we have “free” charging at work for the earliest risers. I think we FReepers all wish that the subsidies and CAFE restrictions were dropped altogether so as not to warp the natural development of the actual alternative energy market. I actually bought a dual fuel gasoline/CNG Ford Contour years ago to save money on my long commute. Awful car, and the CNG part didn’t even work ( nowhere to test it where I bought it),. Now CNG is considered dirty.
Jump in your Tesla,
I’ll be driving a 5.0.
We’re gonna race from
Houston to Albuquerque
in August, when temps are
a nice, toasty, 117 deg/f.
Wanna bet I get there
first?
You compare efficiencies
between ICE and EV power
sources. Once they’re
placed into their working
environments, many things
influence a power sources’
efficiency.
Running the AC, headlights,
wipers, window defroster,
extreme ambient temperatures,
all play a part on the the
efficiency of either power-
plant. In this type scenario,
the ICE vehicle remains on
top, if for nothing else,
for comfort and convenience
(time).
Enjoy your ride. I have a Roush Mustang GT, as daily driver.
What gets me is when people want to DISS other people’s choices.
If you don’t like something (like an EV) don’t buy it. I don’t know why people feel the need to diss something they don’t know about and have never used or experienced.
I don’t diss them. They
serve their purpose
well, but only under
certain circumstances,
where ICE powered vehicles
have had a hundred years
of engineering advances
to make them more efficient
under any circumstance.
Ford’s Lightning vs a F150
pulling 10,000 pounds of
trailer at 75mph in extreme
weather conditions.
I’ll take the F150.
It’s more efficient at
performing the task.
(for now).
I have a F-150 as well (5.0 gas).
Ford electric vehicles are not state of the art.
Neither are chevy’s.
Yep.
