“At least 14 Tarrant County residents died from extreme heat last summer … Of those who died from heat, at least eight cases included residents with no air conditioning, no working air conditioning, or who had their air conditioning turned off at the time of their death…” –The Fort Worth Star-Telegram, June 25, 2023
Air conditioners aren’t supposed to make that sound. The gray-white box in the window had always rattled, but this morning it has begun to grind. The grandmother puts her hand in front of the AC’s dust-covered gills, feels nothing but a weak, lukewarm breeze.
She thinks about calling her daughter, whose husband installed the unit in her trailer’s living room window the summer before. She shakes her head to herself: No, they have the baby; it’s a 40-minute drive; she’s a burden enough as it is. She doesn’t have internet in the trailer to see the day’s excessive heat warning. Her cell phone, another gift from her daughter, is dead more often than it’s not, and she can’t find the weather app on it half of the time, anyway.
But the grandmother has been hot before — prides herself, even, on her 68 Texan summers. Besides, she’s not planning anything strenuous today, which would elevate her chances of exertional, or “activity-induced,” heat stroke — the kind that makes the news for killing the young, fit, and healthy, like the California couple who were found dead on a trail with their 1-year-old baby and dog in 2021, or the stepfather who died last month while trying to rescue his 14-year-old stepson, who also died, while hiking in 119-degree weather in Texas’ Big Bend National Park. Like the dozens of promising high school and college athletes who collapse during training, games, and meets every year.
Or like the characters in longtime Outside correspondent and adventure historian Peter Stark’s cautionary tales about succumbing to the elements. Stark is perhaps best known for his second-person narrative about what it’s like to die from hypothermia, which recirculates every winter, but he has a particular, morbid fascination with heat strokes, having now written two different versions (a competitive cyclist dies in one; a hungover, hiking surfer is brought back from the brink in the other). “Out of all the research I’ve done into ways to die — or come close to dying — heat stroke is the one I found the scariest,” Stark told an Outside interviewer last year.
Like Stark’s characters, the grandmother is fictional and illustrative. Unlike Stark’s characters, she has not elected into risk. Exertional heat stroke is often described as “sporadic” because it is circumstantial; it is also less deadly since an athlete often begins to feel terrible, or collapses, before the point-of-no-return. “Classic” heat stroke, which results from unbearably high temperatures, “occurs in epidemic form” in the sense that it strikes the vulnerable at once and all together: the ill, the elderly, the unhoused, the bedridden, the prepubescent. Though heat-related mortality can be hard to pin down, by some estimates classic heat stroke is fatal in over 60% of intensive care cases — part of the reason extreme heat is credited as the deadliest weather phenomenon in the United States.
The grandmother goes to her sink and fills a glass of water. She looks out the window, at the tall grass growing alongside her neighbor’s trailer, and thinks about her grandbaby. Her trailer, which had stayed cool overnight before the AC conked out, has already begun to feel muggy, but she isn’t alarmed.
It is 97 degrees outside and getting hotter.
The human body is a contradiction: It can run a marathon in under two hours; it can scale the tallest mountain in the world; and it can survive episodes of extreme cold and starvation. At the same time, it is hilariously delicate: Only about 8.2 degrees separate our core body temperature of 98.6 from multi-organ dysfunction, which begins somewhere around 106 degrees, depending on the person and circumstances. Because this leaves little margin for error, our bodies spring into a well-rehearsed response when blood warmed by our environments at the surface of our skin makes its way to our brain, causing our hypothalamus to rustle through its bag of cooling tricks.
The grandmother’s body begins to run through them as the trailer’s temperature rises to 100 degrees, the point at which the body ceases to give off heat and begins to absorb it. Her hair follicles relax to release any trapped warm air against her skin. Her sweat glands are activated, and soon she’s covered in a light sheen that serves to transport heat away from her body via evaporation. Crucially, her blood vessels dilate so that the warmed blood can pass closer to the surface of the skin, where it will ideally be cooled by the heat pulling away from her body.
But as an older adult, the grandmother’s blood vessels don’t dilate as well as they used to. Her body strains to cool itself and her heart pumps harder. And despite her glass of water, the grandmother begins to notice she feels … off. She is experiencing some of the most common heat-related symptoms, the ones most of us are probably familiar with: Her stomach starts to cramp and she feels slightly nauseous as blood is redirected from her gut to the surface of her skin. She begins, also, to feel fatigued — unbeknownst to her, the drowsiness is because her body is running its cooling mechanisms full-blast, compensating for the broken AC.
But today, these systems are fighting an uphill battle. The trailer is humid, meaning the grandmother’s sweat isn’t evaporating as efficiently as it would in dry air. She has a sunburn from sitting on her lawn the day before, and her body is using water to try to heal it, leaving her with less liquid overall to sweat out. She can’t drink enough water to replenish what she’s lost, either, since the human body can only absorb, at max, one liter of water an hour, and those in extreme heat conditions can lose that or more in the same span of time.
Little does the grandmother know, either, that because it’s now over 95 degrees in her trailer, the fan she’s turned on is no longer having any cooling effect. Her core temperature tips toward 100 degrees.
Heat exhaustion sets in when the core body temperature is between 101°F and 104°F, as the grandmother’s is now. (Core body temperature cannot reliably be read on an oral thermometer, which is part of why the Centers for Disease Control and Prevention recommends watching for symptoms of heat exhaustion and heat stroke rather than taking your own measurements). In addition to her fatigue, she now feels dizzy. Her heart is pounding as her body tries to regulate itself; if she had a preexisting cardiac condition, she would be in even more danger than she already is. She stands up to get more water and feels a woosh of lightheadedness — a result of low pressure stemming from her dilated vessels — and her vision momentarily goes black. She nearly faints, but steadies herself with a hand on the back of a chair.
If a neighbor checked in on her, as the weathermen on TV are advising good samaritans do, they would see that the grandmother looks pale, that she’s grown irritable and unfocused. The neighbor might suggest she take a cold shower before asking her to come to their air-conditioned trailer, or a local cooling center, for the rest of the day. The most crucial thing, though, would be that she gets to a safe temperature, and fast, before her core hits 104, the threshold of heat stroke.
In her delirium, the grandmother thinks to take an Advil, foggily hoping a fever-reducer might help lower her core body temperature. And though the damage wrought by extreme heat is similar internally to that inflicted by a dangerously high fever, the response systems at play in each case are completely different. For extreme heat, there is no magic pill, no shut-off switch for how the grandmother is feeling aside from getting somewhere cool.
It might seem like a simple thing: getting somewhere cool. In this sense, classic heat stroke is, agonizingly, preventable. Though most Americans have air conditioning, over a quarter — 34 million households — “said they could not [financially] meet their energy needs at some point” during 2020, according to Energy Information Administration data. Of those who were struggling, 10% reported enduring dangerously high temperatures in their homes due to concerns about cost.
Because Americans typically do have access to AC, though, losing air conditioning for reasons beyond their control — say, due to grid failure, a localized blackout, or a mechanical issue — actually makes people more susceptible to dangerous heat-related illness, in part because acclimation has such a large role in how well we tolerate heat. The shock of living in climate-controlled rooms and suddenly finding yourself without one can be deadly.
The grandmother’s internal temperature is now over 105 degrees and still rising; she is well within the realm of heat stroke. Her pulse is rapid and now she is confused and agitated — she stumbles, directionless, toward her living room and collapses on the floor. Her body is rationing water away from vital organs, like her kidneys, which begin to shut down. Her brain is swollen. She cycles in and out of consciousness on the floor.
Her body is past the point of being able to bring its temperature back down by itself. A heat stroke victim may stop sweating. Their cells begin to die — the cerebellum, which controls motor functions, is one of the earliest parts of the brain to fail. They may have seizures or hallucinate or, nearing the end, feel a soaring sense of euphoria. Internally, the body is in freefall; by one estimate, there are 27 different pathways to death once heat stroke sets in, ranging from heart failure to the proteins that control blood clotting becoming overactive and cutting off flow to vital organs.
When the grandmother’s daughter arrives and calls the paramedics, it will only have been two hours since the grandmother first noticed her air conditioner’s grinding. “That’s part of what makes [heat stroke] so lethal,” Willamette Week wrote after the heat wave in the Pacific Northwest in 2021 killed an estimated 250 Americans: “You can go from feeling bothered by the heat to dead in 90 minutes.”
Victims of classic heat stroke are often elderly, often have pre-existing health conditions, often are socially isolated, and often are low-income. In an analysis of heat deaths in Multnomah County (where Portland, Oregon, is located) in 2021, The Washington Post found 61 percent of confirmed deaths were in areas with above-average poverty rates. In the same story, the reporters found that a “direct outreach” program in Philadelphia — which includes a “mass notification system,” “the number for a 24-hour hotline staffed by nurses [flashing] from one of the city’s tallest high rises,” and a 5,000-strong volunteer team that mobilizes “to check on high-risk neighbors” — saves an average of 45 lives per year.
If the grandmother had been younger, she might have been treated with “cold-water immersion,” which is one of the fastest and most reliable ways to address heat stroke. (Willamette Week reports Oregon paramedics resourcefully filled body bags with ice and had those suffering from heat stroke crawl inside). In the case of the elderly, though, it is advised to treat heat stroke with more easily tolerable cooling methods, like the application of ice packs and cold, wet gauze.
Either way, the outcome past the threshold of heat stroke is uncertain. As Stark, the master of the cautionary tale, writes, “A study reviewing 58 of the severe heat stroke victims [after a 1995 Chicago heat wave] found that 21 percent died in the hospital soon after admission, 28 percent died within a year, and all the remaining subjects experienced organ dysfunction and neurological impairments.”
But he sees a grim silver lining. “It could be a small measure of good fortune,” writes Stark, “that confusion, semiconsciousness, or coma overcome victims as they succumb to severe heatstroke.”
The laborer puts the nail gun down on the nearest cinderblock and sweeps the back of his hand across his brow, a portrait of I’m hot. Though the elimination of water breaks won’t go into effect until the fall, his employer has threatened to fire anyone who “slacks off” anyway, and the laborer needs this job. He watches for a moment as the heat makes strange shapes in the air above the new asphalt driveway. He thinks he might have a headache coming on.
There are five more hours to go. It’s 96 degrees out with 66% humidity.
And tomorrow will be another scorcher.

Businesses were already bracing for a crash. Then came another 50% tariff on Chinese goods.
When I wrote Heatmap’s guide to driving less last year, I didn’t anticipate that a good motivation for doing so would be that every car in America was about to get a lot more expensive.
Then again, no one saw the breadth and depth of the Trump administration’s tariffs coming. “We would characterize this slate of tariffs as ‘worse than the worst case scenario,’” one group of veteran securities analysts wrote in a note to investors last week, a sentiment echoed across Wall Street and reflected in four days of stock market turmoil so far.
But if the economic downturn has renewed your interest in purchasing a bike or e-bike, you’ll want to act fast — and it may already be too late. Because Trump’s “Liberation Day” tariffs stack on top of his other tariffs and duties, the U.S. bicycle trade association PeopleForBikes calculated that beginning on April 9, the day the newest tariffs come into effect, the duty on e-bikes from China would be 79%, up from nothing at all under President Biden. The tariff on most non-electric bikes from China, meanwhile, would spike to 90%, up from 11% on January 1 of this year. Then on Tuesday, the White House announced that it would add another 50% tariff on China on top of that whole tariff stack, starting Wednesday, in retaliation for Beijing’s counter-tariffs.
Prior to the latest announcement, Jay Townley, a founding partner of the cycling industry consulting firm Human Powered Solutions, had told me that if the Trump administration actually followed through on a retaliatory 50% tariff on top of those duties, then “we’re out of business because nobody can afford to bring in a bicycle product at 100% or more in tariffs.”
It’s difficult to overstate how existential the tariffs are for the bicycle industry. Imports account for 97% of the bikes purchased in the United States, of which 87% come from China, making it “one of the most import-dependent and China-dependent industries in the U.S.,” according to a 2021 analysis by the Coalition for a Prosperous America, which advocates for trade-protectionist policies.
Many U.S. cycling brands have grumbled for years about America’s relatively generous de minimis exemption, a policy of waiving duties on items valued at less than $800. The loophole — which is what enables shoppers to buy dirt-cheap clothes from brands like Temu, Shein, and Alibaba — has also allowed for uncertified helmets and non-compliant e-bikes and e-bike batteries to flood the U.S. market. These batteries, which are often falsely marketed as meeting international safety standards, have been responsible for deadly e-bike fires in places like New York City. “A going retail for a good lithium-ion replacement battery for an e-bike is $800 to $1,000,” Townley said. “You look online, and you’ll see batteries at $350, $400, that come direct to you from China under the de minimis exemption.”
Cyclingnews reported recently that Robert Margevicius, the executive vice president of the American bicycle giant Specialized, had filed a complaint with the Trump administration over losing “billions in collectable tariffs” through the loophole. A spokesperson for Specialized defended Margevicius’ comment by calling it an “industry-wide position that is aligned with PeopleForBikes.” (Specialized did not respond to a request for clarification from Heatmap, though a spokesperson told Cyclingnews that de minimis imports permit “unsafe products and intellectual property violation.” PeopleForBikes’ general and policy counsel Matt Moore told me in an email that “we have supported reforming the way the U.S. treats low-value de minimis imports for several years.”)
Trump indeed axed China’s de minimis exemption as part of his April 2 tariffs — a small win for the U.S. bicycle brands. But any protection afforded by duties on cheap imported bikes and e-bikes will be erased by the damage from high tariffs imposed on China and other Asian countries. Fewer than 500,000 bicycles in a 10 million-unit market are even assembled in the United States, and essentially none is entirely manufactured here. “We do not know how to make a bike,” Townley told me flatly. Though a number of major U.S. brands employ engineers to design their bikes, when it comes to home-shoring manufacturing, “all of that knowledge resides in Taiwan, China, Vietnam. It isn’t here.”
In recent years, Chinese factories had become “very proficient at shipping goods from third-party countries” in order to avoid European anti-dumping duties, as well as leftover tariffs from Trump’s first term, Rick Vosper, an industry veteran and columnist at Bicycle Retailer and Industry News, told me. “Many Chinese companies built bicycle assembly plants in Vietnam specifically so the sourcing sticker would not say ‘made in China,’” he added. Of course, those bikes and component parts are now also subject to Trump’s tariffs, which are as high as 57% for Vietnam, 60% for Cambodia, and 43% for Taiwan for most bikes. (A potential added tariff on countries that import oil from Venezuela could bump them even higher.)
The tariffs could not come at a worse time for the industry. 2019 marked one of the slowest years for the U.S. specialty retail bike business in two decades, so when COVID hit — and suddenly everyone wanted a bicycle as a way of exercising and getting around — there was “no inventory to be had, but a huge influx of customers,” Vosper told me. In response, “major players put in huge increases in their orders.”
But by 2023, the COVID-induced demand had evaporated, leaving suppliers with hundreds of millions of dollars in inventory that they couldn’t move. Even by discounting wholesale prices below their own cost to make the product and offering buy-one-get-one deals, dealers couldn’t get the bikes off their hands. “All the people who wanted to buy a bike during COVID have bought a bike and are not ready to buy another one anytime soon,” Vosper said.
Going into 2025, many retailers were still dealing with the COVID-induced bicycle glut; Mike Blok, the founder of Brooklyn Carbon Bike Company in New York City, told me he could think of three or four tristate-area shops off the top of his head that have closed in recent months because they were sitting on inventory.
Blok, however, was cautiously optimistic about his own position. While he stressed that he isn’t a fan of the tariffs, he also largely sells pre-owned bikes. On the low end of the market, the tariffs will likely raise prices no more than about $15 or $20, which might not make much of a difference to consumer behavior. But for something like a higher-end carbon fiber bike, which can run $2,700 or higher and is almost entirely produced in Taiwan, the tariffs could mean an increase of hundreds of dollars for customers. “I think what that will mean for me is that more folks will be open to the pre-owned option,” Blok said, although he also anticipates his input costs for repairs and tuning will go up.
But there’s a bigger, and perhaps even more obvious, problem for bike retailers beyond their products becoming more expensive. “What I sell is not a staple good; people don’t need a bike,” Blok reminded me. “So as folks’ discretionary income diminishes because other things become more expensive, they’ll have less to spend on discretionary items.”
Townley, the industry consultant, confirmed that many major cycling brands had already seen the writing on the wall before Trump announced his tariffs and begun to pivot to re-sale. Bicycling Magazine, a hobbyist publication, is even promoting “buying used” as one of its “tips to help you save” under Trump’s tariffs. Savvy retailers might be able to pivot and rely on their service, customer loyalty, and re-sale businesses to stay afloat during the hard days ahead; Moore of PeopleForBikes also noted that “repair services may increase” as people look to fix what they already have.
And if you don’t have a bike or e-bike but were thinking about getting one as a way to lighten your car dependency, decarbonize your life, or just because they’re cool, “there are still good values to be found,” Moore went on. “Now is a great time to avoid a likely increase in prices.” Townley anticipated that depending on inventory, we’re likely 30 to 40 days away from seeing prices go up.
In the meantime, cycling organizations are scrambling to keep their members abreast of the coming changes. “PeopleForBikes is encouraging our members to contact their elected representatives about the very real impacts these tariffs will have on their companies and our industry,” Moore told me. The National Bicycle Dealers Association, a nonprofit supporting specialty bicycle retailers, has teamed up with the D.C.-based League of American Bicyclists, a ridership organization, to explore lobbying lawmakers for the first time in decades in the hopes that some might oppose the tariffs or explore carve-outs for the industry.
But Townley, whose firm Human Powered Solutions is assisting in NBDA’s effort, shared a grim conversation he had at a recent trade show in Las Vegas, where a new board member at a cycling organization had asked him “what can we do” about Trump’s tariffs.
“I said, ‘You’re out of time,” Townley recalled. “There isn’t much that can be done. All we can do is react.”
Any household savings will barely make a dent in the added costs from Trump’s many tariffs.
Donald Trump’s tariffs — the “fentanyl” levies on Canada, China, and Mexico, the “reciprocal” tariffs on nearly every country (and some uninhabited islands), and the global 10% tariff — will almost certainly cause consumer goods on average to get more expensive. The Yale Budget Lab estimates that in combination, the tariffs Trump has announced so far in his second term will cause prices to rise 2.3%, reducing purchasing power by $3,800 per year per household.
But there’s one very important consumer good that seems due to decline in price.
Trump administration officials — including the president himself — have touted cheaper oil to suggest that the economic response to the tariffs hasn’t been all bad. On Sunday, Secretary of the Treasury Scott Bessent told NBC, “Oil prices went down almost 15% in two days, which impacts working Americans much more than the stock market does.”
Trump picked up this line on Truth Social Monday morning. “Oil prices are down, interest rates are down (the slow moving Fed should cut rates!), food prices are down, there is NO INFLATION,” he wrote. He then spent the day posting quotes from Fox Business commentators echoing that idea, first Maria Bartiromo (“Rates are plummeting, oil prices are plummeting, deregulation is happening. President Trump is not going to bend”) then Charles Payne (“What we’re not talking about is, oil was $76, now it’s $65. Gasoline prices are going to plummet”).
But according to Neil Dutta, head of economic research at Renaissance Macro Research, pointing to falling oil prices as a stimulus is just another example of the “4D chess” theory, under which some market participants attribute motives to Trump’s trade policy beyond his stated goal of reducing trade deficits to as near zero (or surplus!) as possible.
Instead, oil markets are primarily “responding to the recession risk that comes from the tariff and the trade war,” Dutta told me. “That is the main story.” In short, oil markets see less global trade and less global production, and therefore falling demand for oil. The effect on household consumption, he said, was a “second order effect.”
It is true that falling oil prices will help “stabilize consumption,” Dutta told me (although they could also devastate America’s own oil industry). “It helps. It’ll provide some lift to real income growth for consumers, because they’re not spending as much on gasoline.” But “to fully offset the trade war effects, you basically need to get oil down to zero.”
That’s confirmed by some simple and extremely back of the envelope math. In 2023, households on average consumed about 700 gallons of gasoline per year, based on Energy Information Administration calculations that the average gasoline price in 2023 was $3.52, while the Bureau of Labor Statistics put average household gasoline expenditures at about $2,450.
Let’s generously assume that due to the tariffs and Trump’s regulatory and diplomatic efforts, gas prices drop from the $3.26 they were at on Monday, according to AAA, to $2.60, the average price in 2019. (GasBuddy petroleum analyst Patrick De Haanwrote Monday that the tariffs combined with OPEC+ production hikes could lead gas prices “to fall below $3 per gallon.”)
Let’s also assume that this drop in gas prices does not cause people to drive more or buy less fuel-efficient vehicles. In that case, those same 700 gallons cost the average American $1,820, which would generate annual savings of $630 on average per household. If we went to the lowest price since the Russian invasion of Ukraine, about $3 per gallon, total consumption of 700 gallons would cost a household about $2,100, saving $350 per household per year.
That being said, $1,820 is a pretty low level for annual gasoline consumption. In 2021, as the economy was recovering from the Covid recession and before gas prices popped, annual gasoline expenditures only got as low as $1,948; in 2020 — when oil prices dropped to literally negative dollars per barrel and gas prices got down to $1.85 a gallon — annual expenditures were just over $1,500.
In any case, if you remember the opening paragraphs of this story, even the most generous estimated savings would go nowhere near surmounting the overall rise in prices forecast by the Yale Budget Lab. $630 is less than $3,800! (JPMorgan has forecast a more mild increase in prices of 1% to 1.5%, but agrees that prices will likely rise and purchasing power will decline.)
But maybe look at it this way: You might be able to drive a little more than you expected to, even as your costs elsewhere are going up. Just please be careful! You don’t want to get into a bad accident and have to replace your car: New car prices are expected to rise by several thousand dollars due to Trump’s tariffs.
With cars about to get more expensive, it might be time to start tinkering.
More than a decade ago, when I was a young editor at Popular Mechanics, we got a Nissan Leaf. It was a big deal. The magazine had always kept long-term test cars to give readers a full report of how they drove over weeks and months. A true test of the first true production electric vehicle from a major car company felt like a watershed moment: The future was finally beginning. They even installed a destination charger in the basement of the Hearst Corporation’s Manhattan skyscraper.
That Leaf was a bit of a lump, aesthetically and mechanically. It looked like a potato, got about 100 miles of range, and delivered only 110 horsepower or so via its electric motors. This made the O.G. Leaf a scapegoat for Top Gear-style car enthusiasts eager to slander EVs as low-testosterone automobiles of the meek, forced upon an unwilling population of drivers. Once the rise of Tesla in the 2010s had smashed that paradigm and led lots of people to see electric vehicles as sexy and powerful, the original Leaf faded from the public imagination, a relic of the earliest days of the new EV revolution.
Yet lots of those cars are still around. I see a few prowling my workplace parking garage or roaming the streets of Los Angeles. With the faded performance of their old batteries, these long-running EVs aren’t good for much but short-distance city driving. Ignore the outdated battery pack for a second, though, and what surrounds that unit is a perfectly serviceable EV.
That’s exactly what a new brand of EV restorers see. Last week, car site The Autopiancovered DIYers who are scooping up cheap old Leafs, some costing as little as $3,000, and swapping in affordable Chinese-made 62 kilowatt-hour battery units in place of the original 24 kilowatt-hour units to instantly boost the car’s range to about 250 miles. One restorer bought a new battery on the Chinese site Alibaba for $6,000 ($4,500, plus $1,500 to ship that beast across the sea).
The possibility of the (relatively) simple battery swap is a longtime EV owner’s daydream. In the earlier days of the electrification race, many manufacturers and drivers saw simple and quick battery exchange as the solution for EV road-tripping. Instead of waiting half an hour for a battery to recharge, you’d swap your depleted unit for a fully charged one and be on your way. Even Tesla tested this approach last decade before settling for good on the Supercharger network of fast-charging stations.
There are still companies experimenting with battery swaps, but this technology lost. Other EV startups and legacy car companies that followed Nissan and Tesla into making production EVs embraced the rechargeable lithium-ion battery that is meant to be refilled at a fast-charging station and is not designed to be easily removed from the vehicle. Buy an electric vehicle and you’re buying a big battery with a long warranty but no clear plan for replacement. The companies imagine their EVs as something like a smartphone: It’s far from impossible to replace the battery and give the car a new life, but most people won’t bother and will simply move on to a new car when they can’t take the limitations of their old one anymore.
I think about this impasse a lot. My 2019 Tesla Model 3 began its life with a nominal 240 miles of range. Now that the vehicle has nearly six years and 70,000 miles on it, its maximum range is down to just 200, while its functional range at highway speed is much less than that. I don’t want to sink money into another vehicle, which means living with an EV’s range that diminishes as the years go by.
But what if, one day, I replaced its battery? Even if it costs thousands of dollars to achieve, a big range boost via a new battery would make an older EV feel new again, and at a cost that’s still far less than financing a whole new car. The thought is even more compelling in the age of Trump-imposed tariffs that will raise already-expensive new vehicles to a place that’s simply out of reach for many people (though new battery units will be heavily tariffed, too).
This is no simple weekend task. Car enthusiasts have been swapping parts and modifying gas-burning vehicles since the dawn of the automotive age, but modern EVs aren’t exactly made with the garage mechanic in mind. Because so few EVs are on the road, there is a dearth of qualified mechanics and not a huge population of people with the savvy to conduct major surgery on an electric car without electrocuting themselves. A battery-replacing owner would need to acquire not only the correct pack but also potentially adapters and other equipment necessary to make the new battery play nice with the older car. Some Nissan Leaf modifiers are finding their replacement packs aren’t exactly the same size, shape or weight, The Autopian says, meaning they need things like spacers to make the battery sit in just the right place.
A new battery isn’t a fix-all either. The motors and other electrical components wear down and will need to be replaced eventually, too. A man in Norway who drove his Tesla more than a million miles has replaced at least four battery packs and 14 motors, turning his EV into a sort of car of Theseus.
Crucially, though, EVs are much simpler, mechanically, than combustion-powered cars, what with the latter’s belts and spark plugs and thousands of moving parts. The car that surrounds a depleted battery pack might be in perfectly good shape to keep on running for thousands of miles to come if the owner were to install a new unit, one that could potentially give the EV more driving range than it had when it was new.
The battery swap is still the domain of serious top-tier DIYers, and not for the mildly interested or faint of heart. But it is a sign of things to come. A market for very affordable used Teslas is booming as owners ditch their cars at any cost to distance themselves from Elon Musk. Old Leafs, Chevy Bolts and other EVs from the 2010s can be had for cheap. The generation of early vehicles that came with an unacceptably low 100 to 150 miles of range would look a lot more enticing if you imagine today’s battery packs swapped into them. The possibility of a like-new old EV will look more and more promising, especially as millions of Americans realize they can no longer afford a new car.
