EPA EV range estimates challenged by new research

Tesla Cybertruck spotted on the Highway

Published

The Society of Automotive Engineers (SAE) and Car and Driver have published a report challenging the EPA’s EV range estimate calculations.

As revealed by countless surveys, one of the most critical specifications for EV buyers is how far the vehicle can drive on a single charge. But often, without a way to test it themselves, EV customers are forced to use the number printed on the window sticker or posted on the EPA’s website, which is the agency that has typically tracked and measured these capabilities. Now, those numbers are being challenged by research from SAE International and the Car and Driver magazine.

According to the research published by Car and Driver, the EV range estimates published by the EPA are, on average, 12.5% higher than the numbers they achieved in their testing, which could be quite a shock for a car buyer. In comparison, Car and Driver’s ICE vehicle testing was only 4% off of the EPA’s estimates, which were actually lower than their testing results.

As noted in the published report, this range discrepancy was entirely expected, thanks to the difference in testing methodology, but that was ostensibly the point. First, because the EPA only provides consumers with a single highway/city combined range number – which is slightly weighted toward city driving (55/45) – customers who predominantly drive on the highway will consistently fail to reach the estimated range number. Further, the inverse is true for drivers who spend most of their time in the city.

The EPA was not immediately available to comment to Teslarati on their testing procedures.

The second discrepancy point highlighted in the paper concerns testing methodology, in which the EPA currently provides options for automakers on how to complete the testing. This means different automakers, or even different models, will be dramatically different in their estimated range compared to their real-life range, adding to customer confusion.

Nowhere is this second point seen better than in highway testing, which is once again significantly skewed upwards. Instead of testing the vehicles at actual highway speeds, 75mph (the speed used in Car and  Driver’s testing), automakers test at a lower speed and then multiply their results by a “reduction factor,” determined by how many runs the vehicle completes.

Third and perhaps worst of all, these slight discrepancies, mixed with automakers’ self-reporting their results, can mean that different brands take wildly different approaches and report drastically different figures compared to real life. Perhaps the starkest example found by Car and Driver was the difference in EV range reported by Tesla and Porsche. While the German brand was incredibly conservative with its range estimates, Tesla was slightly more generous than the testing completed by the car magazine.

Luckily, according to Car and Driver, fixing these issues would be fairly simple. First, the paper suggests providing consumers with an EV highway and city range number, with each of those estimates being found by separate testing, similar to current gas vehicle testing. Second, removing or adjusting the “reduction factor” toward more realistic use (higher highway speeds) will provide a more accurate number to consumers. And third and finally, enforcing more consistent testing standards between automakers will help consumers more accurately gauge the capabilities of the cars they are buying.

Ford considers drastic move with F-150 Lightning: ‘The demand is just not there’

Published

Ford is considering a drastic move with its F-150 Lightning, which was the best-selling EV pickup on the market last quarter, beating out Tesla’s Cybertruck.

Ford has had a tumultuous entrance into its more expanded electric vehicle strategy over the past several years. At one point, the company was widely considered to be the most invested legacy automaker in the transition to electrification, but as the company has seen some real backtracking in terms of its sales and demand, it is cooling down its commitment.

At the end of Q3, it seemed to already be considering making some moves to cool off its EV ambitions, especially as the $7,500 EV tax credit was removed and it appeared that consumers would be less attracted to its vehicles without this sizeable discount.

Now, according to a new report from the Wall Street Journal, Ford is considering scrapping the F-150 Lightning altogether, as one employee said “the demand is just not there.”

Despite it being the best-selling EV pickup in the U.S. last quarter, the sales simply do not match up with the pricing, and financially, it is not the time to try to dive further into a project that is not making a profit. Ford has been dwindling in its commitment to EVs over the past several quarters, and its profits are reflecting a slowing interest in its electric vehicles.

Simply put, Ford’s combustion engine lineup of pickups in the F-Series is, by far, the best-selling division of trucks globally. Ford brought an awesome product forth with the Lightning, a mirror of the gas-powered F-Series that had a variety of trim levels for whatever the truck would be used for by the consumer.

However, the demand and sales have caused Ford to take a loss on its electric truck: figures from early last year indicated it was losing between $100,000 and $132,000 per vehicle.

It is not an official announcement, as Ford has not publicly said anything regarding its plans for the Lightning at this time.

Tesla schedules Roadster unveiling event, and you won’t believe when it is

Published

Tesla has tentatively scheduled its unveiling event for the Roadster’s next-generation iteration, and you will not believe the date the company picked for it.

Tesla CEO Elon Musk said during the 2025 Annual Shareholders Meeting that the company is aiming for an April 1 demo event.

Yes, April Fools’ Day.

Tesla originally aimed for its “most epic demo” to take place at the end of this year. However, the writing on the wall as 2025 winds down seemed to indicate the company was not quite ready to show off everything it plans to implement into the Roadster.

Its capabilities have been teased quite heavily throughout most of the year, but the biggest hints came last week when Musk appeared on the Joe Rogan Experience Podcast.

He said:

“Whether it’s good or bad, it will be unforgettable. My friend Peter Thiel once reflected that the future was supposed to have flying cars, but we don’t have flying cars. I think if Peter wants a flying car, he should be able to buy one…I think it has a shot at being the most memorable product unveil ever. [It will be unveiled] hopefully before the end of the year. You know, we need to make sure that it works. This is some crazy technology in this car. Let’s just put it this way: if you took all the James Bond cars and combined them, it’s crazier than that.”

The Roadster has been somewhat of a letdown, at least in its newest version, thus far. Tesla has routinely delayed the project, putting those who put lofty down payments on the car in a weird limbo, lost at what to do.

One notable pre-orderer cancelled his reservation last week and got in a spat with Musk about it.

Now that there is a definitive date for the Roadster unveiling, Musk and Co. should have a more definitive cutoff date for features and capabilities. Chief Designer Franz von Holzhausen said earlier this year that when they showed Musk what they had done with the Roadster, the CEO encouraged them to do even more with it.

This delayed things further.

Musk also said he believes production would begin between 12 and 18 months after the unveiling, putting it out sometime in 2027.

Tesla (NASDAQ:TSLA) CEO Elon Musk has officially approved his 2025 Performance Award, a landmark pay package that could make him the world’s first trillionaire and make Tesla the most valuable company in the world by a mile. 

The 2025 CEO Performance Award was officially approved by Tesla shareholders at the 2025 Annual Shareholder Meeting.

Elon Musk‘s landmark pay package

As per Tesla, more than 75% of the shareholders approved Elon Musk’s 2025 CEO Performance Award. It was then unsurprising that the approval of Elon Musk’s pay plan received overwhelming applause from the event’s attendees.

The CEO took to the stage with much enthusiasm, welcoming every shareholder to the event and dancing briefly on stage. Optimus also danced on stage smoothly, demonstrating its improved movements to much appause.

Elon Musk’s 10-year targets

To earn his 2025 CEO Performance Award, Musk would be required to grow Tesla’s market capitalization from about $1.1 trillion today to $8.5 trillion over the next decade. At that level, Tesla would surpass every major public company in existence. The compensation plan also requires Tesla’s operating profit to grow from $17 billion last year to $400 billion annually.
