No offense meant to the Prius! It’s the benchmark for ICE efficiency, which is why it was mentioned. The newest version with AWD is especially impressive.
We’ll have to agree to disagree on safety. There is an abundance of data indicating that larger vehicles are safer in accidents (but worse for the other car). On the highways of CA I would much rather have my family in a 6,000 lb truck than a low to the ground 3,000 lb car.
We’ll see how long batteries last. The precedent from Tesla is up to 500,000 miles.
Someone cut in front of my Rav 4 on a dirt road. Entered the roadway without looking. I tried to brake and swerve around them but couldn’t; I impacted their Kia Sport just in front of the rear wheel. We all got out, shook ourselves off, exchanged information and went on our way (they couldn’t but were fortunately close to home; bent rear axle). Should have been in my more maneuverable but on paper less “safe” Crosstrek. If I had another 0.5 seconds I could have missed them or barely clipped them and the accident might never have happened.
But what if I’d been in a truck? Impact would likely have been 0.5 seconds sooner rather than later. Five thousand pounds or more t-boning a Kia. No more people getting out and exchanging information. Motionless bodies in the other car surrounded by blood. You’re not getting that sight out of your head. Police and insurance agree it wasn’t your fault. So not your problem?
Yes your problem.
Maybe you have to sell that lovely getaway you got built - or your primary residence - because no way no how are going to be able to drive through that intersection again and again after something like that. What if there were children in the car?
That experience put the idea of buying a truck I don’t need for towing or hauling forever out of my mind.
Hertz Global Holdings Inc. earnings missed estimates amid headwinds from Tesla Inc. price cuts and the high price of repairs for electric vehicles.
Tesla has been rapidly dropping its prices to spur sales, which has lowered the resale value of the EVs in Hertz’s fleet by about one-third. Repair costs for EVs have also been higher than expected, about double what the company pays to fix damaged gasoline cars, Chief Executive Officer Stephen Scherr said in an interview Thursday.
Didn’t they go bankrupt? In addition to Teslas having a much higher maintenance cost than ICE, according to Hertz, they also are depreciating very quickly…
You can get a low mileage used 2017 S Tesla for close to $20k … new they were over $90k with tax… FOMO is gone … which the only real value Teslas have… Hertz has tons of used 3 models for sale… close to the price of new ones… They will have to dump them at a big loss… further depressing the used Tesla market.
2100 3s for sale… who is going to pay $20k over retail… especially for a used rental car with 60,000 miles…
I’d suggest that anyone looking to buy a Tesla wait until Hertz goes bankrupt for a second time over this but by the time the dust settles all the batteries in those Teslas will have “bricked.”
ICE cars vs EVs. EVs are massively more energy efficient: 89% vs 20%.
Electricity transport significantly reduces primary energy demand
If we were to electrify transport, we’d need much less energy overall.
When we look at the amount of energy that countries currently use, it can seem like an overwhelming challenge to replace all of this with low-carbon sources.
But, we don’t need to produce the equivalent amount of low-carbon energy. Our current energy stack includes the energy that we actually need, but it also includes all of the wasted energy in converting fossil fuels to something useful. When we switch to electric cars or low-carbon electricity, a lot of that disappears.
We can demonstrate that with transport.
Great Britain currently uses the equivalent of 445 TWh from petrol and diesel road vehicles. As we’ve just calculated, if this was electric we’d need just 118 TWh. Almost 4 times less. Our energy demand has shrunk dramatically.
Actually, not really Apple to Apple comparison because electricity is not a raw material. It is a processed energy from oil , solar, wind and water. Wondering how efficient is power generation plants.
So is gasoline. You don’t stick crude oil into your car. You need refineries.
What makes EV greener is that electricity can come from sustainable sources like wind and solar. Gasolines can only ever come from crude. Moreover, a huge central power plant is more energy efficient than tiny ICE engines on each and every ICE car, and are better equipped to deal with the resulting pollution, even if the electricity comes from burning hydrocarbons.
…a huge central power plant is less energy efficient than tiny ICE engines on each and every ICE car, and are unable to deal with the resulting pollution, if the electricity comes from burning hydrocarbons.
Anyhoo I suspect is more efficient but not sure by how much since I didn’t do DD so I merely wonder. I doubt you did any DD. So don’t make an authoritative statement as if you’re had.

Since you don’t like “processed”, use “converted” or “transformed”. Processed is used because is not raw, to indicate there is a loss of energy when converting from one form (oil) to another (electricity)… to follow your original statement of “power efficient” which is “loss of energy” when converted from electricity or gasoline to kinetic energy. There is no conversion from crude oil to refined oil (gasoline)… energy is used to refine (expended), not “loss of energy” due to conversion. So again your comparison is not apple2apple.
Here are some efficiency rates for different types of power plants:
Coal: The global average efficiency is 34%.
Natural gas: The global average efficiency is 40%.
Oil: The global average efficiency is 37%.
Hydro: The efficiency rate is 90%. This is because dams funnel water directly to turbines, which results in very little energy loss.
Nuclear: The efficiency rate is around 33-37%. However, more modern designs like the Generation IV nuclear reactors could potentially reach above 45% efficiency.
Most US electric power is generated from natural gas. So let’s use that 40% number.
