Which might make one wonder: Why is Subaru not the Subaru of EVs?

When the Rivian R3 rolled onto the stage in Orange County, car fans saw a flicker of the past. The truncated EV reminded automotive Twitter and Threads of throwback off-road hatchbacks with unusual shapes — the Lancia Delta, AMC Gremlin, Lada Niva, and even the maligned Yugo. It reminded me, in spirit more than silhouette, of the Subaru Outback from a quarter-century ago.
Remember the old Outback? Before it blew up and became just another crossover in a sea of indistinguishable cars, the Outback was a two-tone granola wagon with lesbian cred and font stylings borrowed from Raiders of the Lost Ark. It was a cobbled-together quirky legend built for specific tribes, particularly those who wanted to traverse the craggy roads and highways of America’s backcountry. Its sluggish acceleration couldn’t compare with a futuristic torque monster like the R3 will be, yet it inspired a cult following among the road atlas generation of adventurers that Rivian hopes to duplicate in the age of massive touchscreens.
Even as its cars became more generic and ordinary in the 21st century, Subie kept its marketing efforts aimed at the outdoorsy, dog-loving folks who had become loyal to the brand. However, while its fans are the kind of people with a clear, vested interest in addressing climate change, the world’s “we love the parks” car company has dragged its toes on joining the electric vehicle revolution that hopes to slash the car industry’s carbon emissions. Subaru’s electric aversion left a giant hole in the market for an adventure EV, one that Rivian seeks to fill.
We’ve been hard on Toyota for coasting on the sustainability reputation of the Prius. The world’s largest automaker has been content to tout its “electrified” lineup of mostly hybrids and plug-in hybrids, waiting for EV technology and infrastructure to mature before it jumps in. Subaru, for all its exercises in Earth mother branding, has done the same.
To its credit, Subie made most of its cars follow “partial zero emissions” standards reflected by the PZEV badge you see on the back of a modern Forester. This means the engine burns normal gasoline, but is built with characteristics that reduce smog-forming air pollutants. PZEV tech does nothing to reduce a car’s greenhouse emissions, but it’s about the best a non-hybrid, plain-old combustion car can do.
But Subaru never bothered to build even a Prius-esque MPG-maximizer. And it has been even more reluctant than its partner, Toyota, to join the battery revolution. Subaru’s only entry, the now-canceled plug-in hybrid variant of the Crosstrek, posted a paltry 17 miles of electric range before reverting to gas. According to Green Car Reports, the hybrid Crosstrek was effectively a “compliance car” — something automakers build to satisfy stringent regulations like the state of California’s, not because they believe in the vehicle.
The Crosstrek PHEV can die because Subaru finally has an EV: the Solterra, built on the tech platform Subaru developed in cahoots with Toyota. It is the same car as Toyota’s debut EV, the bZ4x, but with Subaru badges. The Solterra’s angular looks surely will appeal to somebody, and the car will satisfy superfans’ desire for any fully electric Subaru. But the Solterra is an uninspired crossover with a 228-mile range that can’t compare with the current state of the art. It certainly hasn’t generated the reaction of the R3.
For those willing to ignore the climate crisis, the naked business case for ignoring zero-emission technology in the present is clear. Even as the EV age bubbles up around them, the least-electric car brands are selling lots and lots of cars. Americans bought more than 15 million vehicles in 2023, and 632,000 of them were Subarus, a 14% increase from the year before. Subaru didn’t lose money on EVs like Ford has as it tries to establish its battery business. With EVs now stuck between early adopters and the mainstream, it’s possible to make the case that the holdouts are cynical, but smart.
It’s also not easy to build an electric car that does what a Subaru is supposed to do. I’ve driven across the empty expanses of the American West in a two-wheel-drive Tesla Model 3 that started its life with an EPA-rated 240 miles per charge. It was challenging. Subzero temperatures at Bryce Canyon punished the battery. The craggy, icy road into Canyonlands National Park pushed the iffy ground clearance to its limit. The range was barely enough for us to tempt fate by leaving the interstate and crossing the rugged interior of Utah, a decision that saw me end up borrowing — you guessed it — a friendly stranger’s old Subaru Outback while my Tesla charged.
You’d want an small electric vehicle built for adventure to ride taller and go farther. Well, they built one. It’s a Rivian. The rally car-inspired R3 promises to pair fat tires and promising ground clearance with outdoorsy-minded details such as fold-flat seats, a movie-projecting rooftop tent, and a rear-mounted cargo box. The new Rivians should come with at least 300 miles of range, which ought to be enough to reach most far-flung locales as the map of fast-charging stations continues to fill in.
This isn’t to say Subie doomed itself by dithering. For all the excitement over Rivian’s new offerings, the R2 remains at least two years away from realization, and the little R3 even longer. Besides, Rivian’s biggest obstacle isn’t Subaru, but survival. The startup burns through billions of dollars each year and needs to persist on sales of its large, expensive R1 SUVs and trucks until the mass-market models go on sale.
In the meantime, Subaru could trot out a battery-powered Crosstrek and sell a bunch of them to people who’ve been buying fossil fuel Subies for decades. That looks like the plan: The brand now says it will launch a quartet of EV crossovers (possibly the current Crosstrek-Outback-Forester-Ascent lineup, but electric) by 2026, just in time to compete with the R2 and R3, and build 400,000 EVs per year by 2028.
Yet something has been lost. Every time Subaru trots out a new gas-burning vehicle on a stage meant to mimic the high desert or advertises its corporate contributions to the National Park system, it tries to reinforce its status as the car for the Earth-conscious. Stalling on EVs may have been the easy business decision, but the brand has given away excitement that it could have owned, if only they’d trotted out an EV with the spirit of that quirky old Outback.
Or do an Impreza hot hatch EV. As the response to the R3 demonstrated, we’re ready.

SoftBank’s error and Nvidia’s scandal suggest data centers may have already peaked as an economic and energy trend.
This is Heatmap Daily, a weekday digest written by our executive editor. Subscribe here.
Covering energy and climate change sometimes means seeing certain stories in a different light than others. And a particularly vivid hue illuminated The Wall Street Journal’s report today that the Japanese conglomerate SoftBank Group is taking a $3.7 billion loss on several gigawatts’ worth of natural gas turbines.
For the Journal, the big news is that SoftBank and its billionaire founder, Masayoshi Son, are failing to capitalize on the artificial intelligence boom. But at Heatmap, we’re thinking about the turbines.
The data center boom and the return of electricity load growth has depleted the world’s supply of natural gas turbines. SoftBank had purchased reservations for about 13 gigawatts of turbines, according to the Journal. That’s a staggering amount of electricity — it could meet New York City’s maximum power draw on the hottest part of a summer’s day. The conglomerate now seems set to dump reservations for about four gigawatts’ worth. Keeping a reservation, it turns out, really is harder than making it.
Most of those rotors were reportedly from GE Vernova, one of the world’s largest producers of gas turbines. GE Vernova’s order list for gas turbines has been filled for nearly two years and the waiting list now stretches into 2031. That has led data center developers, hungry to get power as soon as possible, to reach for ever dirtier forms of electricity generation, including diesel generators and even old jet engines.
On that front, SoftBank’s failure to sell the turbines to a higher bidder suggests (albeit weakly) that demand for energy-producing assets might not be as strong as the AI boom’s backers once thought. SoftBank was already set to send about 9 gigawatts of turbines to the enormous Trump-backed OpenAI data center in Pike County, Ohio. The roughly remaining four gigawatts will be released back their manufacturers. (One thing this news can’t quite tell us, alas, is what type of turbine set-up will be used in the Pike County facility, which will be the world’s largest gas-fired power plant if it is build to completion. Recent public filings have suggested the facility isn’t planning on using any turbines in the more efficient combined-cycle configuration, which would mean the plant’s carbon intensity will be worse than most other new natural gas plants. But we’d love to hear any tips on this front.)
To zoom out for a second, I’m struck by how the AI bubble has been replaced by an AI muddle. As I wrote this, news emerged that Nvidia is preparing to fire its CEO, Jensen Huang, for his affair with a Chinese woman who is alleged to be a spy. (He had at least one more affair with another Nvidia executive, according to The New York Times.) Under Huang’s leadership, Nvidia has invested in a sprawling and sometimes circular network of energy-related companies, including Emerald AI, a startup that helps data centers flex their electricity consumption, and Redwood Materials, a battery recycler and producer led by the former Tesla executive J.B. Straubel. Huang has used Nvidia’s enormous balance sheet to buy down the risk of other AI and AI-related companies, propelling the overall AI trade to become the biggest story in American markets.
Now that balance sheet is in peril: Nvidia’s stock is already down 11% over the past five days, and it has fallen another 8% in after-hours trading since news broke of Huang’s ouster. If the chip designer’s financial network began to fray — or even if the next CEO had a lower risk appetite than Huang — then its demise could impact a much larger set of firms.
Even before the Huang scandal broke, companies at the center of the AI trade were showing signs of weakness. Alphabet, Meta, and Microsoft are all down on the month. Nvidia was already lagging by about 10% on the month before its hebdomas horribilis began, too. The memory and chip makers Micron and Applied Materials are both down more than 25% in about the same period, and GE Vernova and Oklo have fallen nearly 20%. Although the data center company Coreweave rebounded on an earnings beat today, it’s still down 24% on the month and nearly 50% since May.
The market rout isn’t total — Anthropic seems likely to enjoy one of the largest IPOs ever in the next week (although perhaps not with quite as large a valuation as its investors once imagined). And the underlying technology of AI seems to be getting worryingly better all the time. But even though the politics of data centers and AI seem set to dominate the new Washington, I’m wondering if data centers as a mainstream economic trend might have already peaked. Americans voted for a more subdued AI boom in the midterms. Now it seems like they might get it ahead of schedule.
Lunar Energy’s latest AI-powered system aims to integrate EVs into the automated demand response mix.
In theory, it’s straightforward to assemble the smart energy home: Solar panels, home backup batteries, and electric vehicles, plus smart thermostats, heat pumps, and water heaters — all the individual pieces can be had for the homeowner who can afford the up-front cost. The challenge is getting all those pieces to talk to one another.
Bay Area-based Lunar Energy is one of the tech firms that’s been trying to crack this problem. Today, it announced an upgraded version of its artificial intelligence-powered home energy control system, which not only integrates all those separate systems but also responds tactically to energy markets. CEO Kunal Girotra told me Lunar AI saves its users money by monitoring their home 24/7 and making decisions to charge, not to charge, or discharge so that they save the most money.
“Utilities are all moving to almost-real-time changes of rates,” he said. “You need software to handle that for you. I think that the race is on for who has the best AI machine learning algorithms to save the most amount of money. And so far, we seem to have a head start.”
Lunar’s first-generation system focused on generation, storage, and control. In other words, it connected elements like a home’s rooftop solar panels with the backup battery the residents might keep in the garage, using the AI to decide when to meet the home’s real-time energy needs with solar versus grid energy versus stored power. What it didn’t have was the ability to work with electric vehicles to manage charging and use the car’s battery as a bonus source of energy.
To fix this, Lunar has built its own bidirectional EV charger — one that can charge up the battery or discharge the car’s battery for a secondary use, like backing up the home’s power supply. Girotra, formerly the head of Tesla Energy, told me the problem with that functionality to this point has been the connection point between the car and the home electrical system. Carmakers and other companies in the space didn’t have the deep experience with electrical certifications to make the process seamless, he tells me. That led to setups like the original Ford Charge Station Pro, which required several different wall-mounted electrical boxes to connect the F-150 Lightning EV to the home.
Lunar’s charger is built to connect to its customers’ existing home Lunar energy system, which includes a microgrid interconnect device they call Lunar Bridge that islands the home in case of a power outage on the grid. In that way, the power stored in the EV battery is ready to back up the home in case of a blackout without any additional work — or to be optimized as part of a fully smart home that’s making money as part of a virtual power plant.
The company’s setup allows for another fun feature: “slow” charging that’s not slow at all, but actually two or three times as fast as the Level 2 charging most EV owners use to recharge their batteries overnight. Electric cars in the U.S. can typically take on only about 11 kilowatts of AC power from one’s home because of the limitations of their on-board hardware. Because Lunar’s system is fully DC, however, Girotra said the company decided to build a DC home charger, one that — like a Tesla Supercharger or other DC fast chargers out in the world — isn’t limited by that power cap. Lunar said it could use a combination of power from the grid, home solar, or home batteries to charge an EV at up to 25 kilowatts. That’s enough to recharge an EV in three to four hours rather than six to eight.
“If the standards get high, and if everybody sees cars can get charged in three hours, then all of a sudden people are like, ‘Wow, this is how I want it,’” he said. “Especially for 25% of the users who are like me, who always are running low on charge and they don’t mind a boost every now and then.”
Some of the other improvements in the second-gen system are more incremental. An inverter that’s 40% more powerful helps Lunar get its system up to enterprise scale. That’s crucial, as the world moves toward a place where more homes and businesses employ battery backup systems. Lunar’s new batteries come in modular 5 kilowatt-hour blocks ranging from 10 kilowatt-hours to 30 kilowatt-hours in a single unit and scale up to 300 kilowatt-hours for home or small commercial use; there’s also new pad-mounted configurations with capacity up to 1 megawatt-hour.
Batteries, though, are the simple part. Everyone from EV makers like Rivian to utilities like Octopus Energy is racing to make a person’s or a business’s batteries and solar panels and electric cars work for them, using the power of AI to account for moment-to-moment changes in energy prices and supply. Lunar’s new tech makes the case that the most important element is a single brain to integrate every last smart, electrified thing in your house.
The fundraise comes on the heels of a $50 million grant from the Department of Energy.
Almost all lithium-ion batteries on the market rely on graphite for their anodes, more than 90% of which is processed in China. That concentration has created a chokepoint in the Pentagon’s supply chain as the military increasingly turns to batteries to help its transportation network operate more quietly and reduce reliance on complex refueling logistics.
So when Congress passed the latest National Defense Authorization Act at the end of 2025, barring Chinese-linked battery materials from military use starting in 2028, Coreshell saw an opening. While the California-based silicon-anode battery startup had previously focused on automakers as its beachhead customers, it’s now shipping its first battery cells to the military for use on Navy ships and Army ground vehicles. On Wednesday, Coreshell announced a $30 million Series B to scale up manufacturing operations to meet the needs of this growing customer base.
“We’re entering a new stage where we’re no longer, I would say, demand limited,” Coreshell’s CEO Jonathan Tan told me. “This year we’ve had to put on second and third shifts, work nights and weekends, just to get the product out the door.”
Coreshell sets itself apart by going a step further than the NDAA requires. The law doesn’t make suppliers trace battery materials all the way back to the mine, which would be exceedingly difficult given China’s dominance across the battery supply chain. But Coreshell has nevertheless eliminated Chinese sourcing from its anodes by replacing graphite with silicon mined and refined in the U.S. by Ferroglobe, one of its Series A investors.
Ferroglobe and global investment firm Access Industries led the latest round, with defense contractor ADS also joining as a new strategic investor. The financing comes on the heels of a $50 million Department of Energy grant that Coreshell secured in August as part of a program to strengthen the domestic battery supply chain. That funding will support the company’s first commercial-scale facility, a 2-gigawatt-hour factory.
That’s about 20 times the size of the 100-ish-megawatt-hour plant the startup had originally envisioned, as the DOE grant has allowed Coreshell to “expand much further than we were originally expecting,” according to Tan. The company is now evaluating several potential U.S. sites and expects to announce its selection early next year. For now, it relies on unnamed contract manufactures, along with its small pilot line in San Leandro, to produce its cells. But once the gigafactory gets up and running, the startup plans to bring electrode production in house by 2028, followed by full cell assembly in 2029.
Building this plant will ultimately require significant additional capital. But Tan believes this latest vote of confidence from the federal government will help Coreshell to diversify its capital stack as it continues to fundraise. “That’s one of the great things about having such a notable DOE award is that it also allows us to attract multiple forms of capital,” he told me.
Silicon has long been recognized as a promising alternative material for battery anodes, as it can store far more energy than graphite. The catch is that it tends to swell during charging, causing it to break down quickly and ultimately leading to a much shorter cycle life. Coreshell says it’s extended its anode’s lifespan by giving it a proprietary coating, which Tan told me back in April essentially means “painting the inside of your battery” with an ultra-thin protective layer.
Other companies, such as Sila Nanotechnologies and Group14 Technologies, are also working to commercialize silicon anodes. But Coreshell says many of its competitors rely on more highly engineered, expensive forms of silicon, such as silane gas. By contrast, Coreshell uses metallurgical silicon, a cheap, raw commodity already widely used in aluminum alloys. That, Tan argues, gives the company a cost advantage not only over its competitors, but potentially Chinese graphite too.
Coreshell hasn’t yet demonstrated that its cells can meet the performance demands of the automotive industry, however. When the company raised its Series A in early 2025, it said it expected its automotive cells to exceed 1,000 charge cycles while retaining 80% of their original capacity. But Tan told me many defense applications don’t require such demanding performance targets, as Navy ships and ground vehicles are “not intending to have as many miles or missions or use cases on that same battery” as a consumer EV would.
That doesn’t mean the company is abandoning its automotive ambitions. As Tan pointed out, electric vehicles remain by far the largest source of global and domestic battery demand. “It’s natural for us to obviously utilize the security supply chain first,” he told me. “That allowed us to really get to commercialization, revenue, and production faster, because automotive qualification is this longer journey. But ultimately, we want to do both of those and more.”
