Car & Driver recently published a study conducted in collaboration with SAE International to see if EV’s are as good as they are touted as being. But unfortunately they are not, as the gas-powered cars performed just as good or even better. And yet the marketing for EV’s are overhyped, inflation, and simply disingenuous; especially considering that EV’s cost more than a car/truck with a combustible engine.
And yet car manufacturers like Ford and General Motors are going all-in with EV production, as are others like Honda.
Last year the state of California ruled that sale of gas-powered cars will officially be phased-out by 2035, but many other states have laws on the books that mean they will be following California’s lead. Therefore, car manufacturers have no real incentive to keep producing gas-powered cars and trucks, and instead will slowly convert to more EV production.
For more on the test results, Car & Driver provide more details:
A new paper published by SAE International uses Car and Driver‘s real-world highway test data to show that electric vehicles underperform on real-world efficiency and range relative to the EPA figures by a much greater margin than internal-combustion vehicles. While the latter typically meet or exceed the EPA-estimated highway fuel economy numbers, EVs tend to fall considerably short of the range number on the window sticker. The paper, written by Car and Driver’s testing director, Dave VanderWerp, and Gregory Pannone, was presented this week at SAE International’s annual WCX conference. It points to a need for revised testing and labeling standards for EVs moving forward.
Basically we’ve taken a look at how vehicles perform relative to the values on the window sticker, looking at the difference between what the label says and what we actually see in our real-world highway test.
We see a big difference in that gap between gas-powered vehicles and the performance of EVs. The real question is: When first-time customers are buying EVs, are they going to be pleasantly surprised or disappointed by the range?
Explained VanderWerp.
On Car and Driver‘s 75-mph highway test, more than 350 internal-combustion vehicles averaged 4.0 percent better fuel economy than what was stated on their labels. But the average range for an EV was 12.5 percent worse than the price sticker numbers.
One reason the paper suggests for why EVs fail to match expectations is how the range is calculated. While separate city and highway range figures are computed behind closed doors, only a combined number is presented to consumers. The combined rating is weighted 55 percent in favor of the city figure, where EVs typically perform better. This inflates the range estimates, making it harder to match in real-world highway driving. The paper proposes publishing both city and highway range figures—as with fuel-economy estimates for gas-powered vehicles—to give shoppers a more holistic sense of a vehicle’s abilities.
The way the tests are conducted also skews the reported range figure. Unlike Car and Driver‘s real-world test—carried out at a constant 75 mph—the EPA’s cycle is variable, with the speed increasing and decreasing over the course of the test. While this is detrimental to the results for gas vehicles, which tend to be most efficient at a steady rpm, the ability to regenerate energy under braking leads to higher range results for EVs, which are shifted even higher by the slight bias towards the city results in the combined rating.
The EPA’s highway cycle is conducted at significantly lower speeds than Car and Driver‘s 75-mph test, with the initial EPA results then multiplied by a reduction factor to simulate the effect of higher speeds. Automakers can chose between running a two-cycle test—where the data is multiplied by a standard 0.7 adjustment factor—or carrying out a five-cycle test in an attempt to earn a smaller reduction factor, making the label figure higher. That means range figures aren’t perfectly comparable across different vehicles.
“There’s a balance,” explained VanderWerp. “The marketing team wants to tout a big range number, but to customers you want to be conservative.” This leads to different approaches from various brands. The German automakers—BMW, Mercedes, Audi, and Porsche—typically provide a relatively conservative range figure, allowing us to meet or even at times exceed the range numbers in Car and Driver‘s real-world tests. Tesla, meanwhile, pursues an impressive figure for its window stickers, and ends up returning real-world results that are on average two times as far off the label value as most EVs. A range discrepancy between EVs from different companies might not be as extreme as the numbers would suggest. “400 miles of stated range for a Tesla and 300 miles for a Porsche is pretty much the same number at real highway speeds,” VanderWerp said.
The paper recommends that the EPA shift the reduction factor closer to 0.6, which would result in range estimates that closely correlate with the results of the real-world efficiency test. But having the same test procedure for all cars is also crucial.
Every automaker could aggressively use the five-cycle test and get a better reduction factor, but then more people end up being disappointed in the numbers. They should all be tested the same, and it should be closer to the real world than it is now.
VanderWerp said.

AUTHOR COMMENTARY
The wisdom of the prudent is to understand his way: but the folly of fools is deceit.
Proverbs 14:8
Regulars of The WinePress know that for the longest time that I have said that the EV push is all about control, and has absolutely nothing to do with the environment. Not only are these hunks of junk not as fuel efficient as initially touted, but the amount of “dirty energy” and the amount of mineral and metal mining that it takes just to produce these batteries and components obviously contradicts being environmentally friendly.
But as I said, it’s all about control. They are not as fuel efficient and they take forever to charge, and need to be charged quite frequently. In truth, they are really designed to be taken for a Sunday stroll and not far at all. Furthermore, it is really only designed to disrupt and destabilize the market. People cannot afford regular cars as is, and they certainly cannot afford an EV; and to backtrack production is going to time, and would be a ginormous loss of money for these companies.
In the end, “You’ll own nothing and be happy” is the end goal. One week after the California car emissions bill passed, a new law was introduced that would pay people a $1,000 to not own any car.

[7] Who goeth a warfare any time at his own charges? who planteth a vineyard, and eateth not of the fruit thereof? or who feedeth a flock, and eateth not of the milk of the flock? [8] Say I these things as a man? or saith not the law the same also? [9] For it is written in the law of Moses, Thou shalt not muzzle the mouth of the ox that treadeth out the corn. Doth God take care for oxen? [10] Or saith he it altogether for our sakes? For our sakes, no doubt, this is written: that he that ploweth should plow in hope; and that he that thresheth in hope should be partaker of his hope. (1 Corinthians 9:7-10).
