Isn't it normal to have between 15-20km/KWh, that's 4-5 times less efficient. Our car obsession is showing how wasteful we are.
Not to mention that if this tank goes into an accident, the force experienced by the passengers in the other car would be a couple of times higher compared to the force experienced in the passengers of the IQ, practically making this a road kill machine.
Nah, not at all that high. A typical EV gets around 3-4 mi/kWh, which is about 4-6.5km.
For comparison, 1 gallon of gas is 33.7 kwh of energy, so 3m/kwh is 3*33.7 = 101.1 mpge
So the numbers look low, but they're certainly not low in comparison.
Eh, that's a bit disingenuous in terms of consumer cost though. Where I live, gas is $3.90 per gallon and electricity is $0.19 per kWh. That puts gas at $0.11 per kWh. That still puts the Escalade IQ at 58mpg, but it's getting awfully close to some (admittedly much smaller) hybrids. And that's not to mention that that's the price for home charging - public charging is closer to $0.40 per kWh. That still puts it around half the cost per mile of a gas Escalade.
With a starting price of $50k more than the gas model you're talking 300,000 miles to break even (assuming 100% home charging).
My comment wasn't necessarily addressing cost as opposed to how to calculate efficiency. Cost gets much weirder. Nobody can accurately determine the price that anyone else pays for electricity unlike gas, because solar and time of usage exists not to mention the percentage of time home charging comes into play. Washington Post ran a pretty good article on this recently.
Either way ignoring cost, the EV will always be more efficient. That doesn't mean it will always be cheaper.
Sure, but if we want the typical consumer to choose an EV over an ICE then it would need to be cheaper.
You're stating a different point that I'm making. I'm consistently saying "I'm not talking about price", then you go back to price. The initial OP stated that the car obsession is showing it's wasteful, because it consumes a ton of resources. Someone corrected the OPs understanding of the average efficiency of electric cars. I provided the EPA agreed-upon conversion of MPG -> MPGe. You then decided that efficiency = cost. It's not.
Yes, for most use-cases an electric car will be cheaper; you can read about that here. There are some use-cases today where it won't be. But it wasn't the point of my post. Whether or not it's always cheaper, using an EV Escalade vs a gas Escalade will always be more efficient.
