Let’s talk about the Ramcharger 1500 — and why it’s different from a plug-in hybrid.
The American car buyer is a hard one to satisfy.
The freedom of the open road is embedded in our consciousness in a way it is in few (if any) other countries. A typical American consumer may want to be able to embark on a summer road-trip across the United States’ vast distances, to cram in a family of five and all their camping supplies (and maybe a dog and a canoe!), or to hitch up a trailer to haul a boat or RV wherever they might want to adventure.
We may not use all those features most of the time, but we don’t want to make a major purchase like a car, truck, or SUV to meet the average use case; if we can afford to, we buy for the edge case.
That’s why I can’t stop thinking about a recent announcement made by Stellantis, the Euro-American conglomerate behind brands like Dodge, Jeep, Ram and Alfa Romeo.
For model year 2025, Stellantis will electrify its full-size Ram 1500 pickup, following in the footsteps of GM and Ford. But unlike its rivals, Stellantis will offer the Ram 1500 REV in both an all-electric model (with 350-500 mile range) and a "range extender" Ramcharger 1500 that features around 140 miles of electric range — plus a V6 engine mated to a generator to power the vehicle when the battery is depleted.
I think it’s brilliant.
This kind of range-extended EV seems like the ideal near-term product to satisfy some of the trickiest American market segments to electrify: namely the uniquely American demand for full-size pickups and massive SUVs.
I’ve been a critic of plug-in hybrid vehicles as a bridge to an electrified future in the past. But I’ve leveled that critique against the popular “parallel” plug-in hybrid architecture, which features both a conventional internal combustion engine and mechanical transmission plus a battery and electric motor/generator.
Despite Toyota’s reputation for hybrids, Stellantis is actually the undisputed king of plug-in hybrids in the U.S. already, with plug-in hybrid versions of popular models like the Jeep Wrangler and Cherokee and the Chrysler Pacifica minivan selling at a record pace in recent months.
While this common plug-in hybrid architecture could be right for many Americans reluctant to fully electrify (especially those without access to dedicated Level 2 charging), they suffer from one big drawback: they carry around the full drive train — and all the baggage and cost — of both a conventional gas-burning vehicle and a full battery EV. Duplicate drivetrains means they’ll never be cheaper than a pure internal-combustion or electric car. And with limited space on board to cram in a big battery, these vehicles sport a modest 20-40 mile all-electric range.
(Listen to this recent episode of Shift Key for more on my problems with plug-ins and a discussion of recent U.S. electrified vehicle trends)
In contrast, a “range-extended EV” or “series” plug-in hybrid (or whatever we start calling this other third thing) like the new Ramcharger is a fully electric-drive vehicle. There’s no mechanical transmission to power the wheels. It simply has a compact gasoline engine, tuned to run at a single, most-efficient speed, married to a generator that can produce electricity to run the electric motors when the battery is depleted.
Thanks to the extended range provided by the gasoline generator, these vehicles can drop battery mass and cost, squeeze in a gasoline engine and fuel tank, and still come out comparable on cost as a pure EV with substantially longer range than parallel plug-in hybrids.
The Ram 1500 EV needs a massive 229 kilowatt-hour (kWh) pack to deliver an as-advertised 500 mile range. (The 168-kWh battery for the 350-mile-range version is also huge, 85% larger than the pack in my extended range Mustang Mach-E which gets about 300 miles range.)
In contrast, the Ramcharger has a 92 kWh pack and offers about 145 miles of all-electric range.
The range-extended series hybrid thus sheds 137 kWh of batteries vs. the 500 mile range EV. At about $100+ per kWh to manufacture and assemble those incremental battery cells, that saves Stellantis at least $14,000 to manufacture the truck. A new V6 engine costs about $5,000-10,000 retail and surely much less for an automaker to manufacture, so swapping batteries for the V6 nets a significant cost savings.
The economics and capabilities of a range-extended EV thus make a lot of sense, especially for massive vehicles like the full-size trucks and SUVs so many Americans love. And they squash any concerns about range anxiety that might give buyers pause — especially those interested in towing something, which decimates the range of the all-electric pickups on the market today.
At the same time, more range-extended EVs on the road would reduce demand for D.C. fast chargers — which are especially scarce in the more rural areas of America where the full-size pickup is king. You can still charge these vehicles at a D.C. fast charger (if you can find one), but you can also pull into any gas station to extend range on road trips.
Meanwhile, a 100+ mile electric range is sufficient to cover around 99% of trips taken in personal vehicle in America. Plus, even when running in generator mode, a series electric drive train with regenerative braking is more efficient than a pure internal combustion drive (especially when the internal combustion generator can bypass the battery to directly power the electric motors, as it can in the Ramcharger). Near-term adoption of range-extended EVs could deliver substantial reductions in both emissions and gas use.
Sound familiar? That’s because this was exactly how the original Chevy Volt and BMW i3 range extended option were configured way back in 2011. Why GM didn’t continue down this path to electrify their massive Silverados, Sierras, and Escalades is beyond me.
Stellantis isn’t the only automaker going down this path. Mazda has struggled to get a competitive EV out, with their MX-30 offering a paltry 100-mile range. So they’re launching a range-extended version with a compact 830cc rotary engine (one of Mazda’s core IPs), which could turn the compact SUV into a truly viable product. Across the Atlantic, Nissan also offers a series hybrid drivetrain marketed as e-POWER in Europe and the U.K.
Building range-extended battery EVs is also a good way for manufacturers to develop experience with all-electric vehicle architecture and achieve economies of scale in production. A series hybrid can ride on the same all-electric platform as a full battery electric variant — as in the case of the Ram 1500 REV and Ramcharger — which is key to keeping manufacturing costs low. (Several Chinese automakers took this route.) In contrast, a parallel plug-in hybrid always shares a platform with its pure fossil fueled siblings.
Finally, the U.S. is embarking on a strategic effort to onshore and “friend shore” the whole EV battery and critical minerals supply chain. It’s going to be a serious challenge. Cutting the size of battery packs in electric full-size pickup and SUVs in half makes that a lot easier.
So are range-extended EVs with 100 mile range the electrified vehicle Americans are waiting for? If they're demanding big vehicles, towing capacity, and long-distance travel away from cities and interstates — e.g. exactly the segments hardest to satisfy with a pure EV — the answer might be yes.
Editor’s note: A previous version of this article used “personal vehicle miles traveled” instead of trips taken in personal vehicles. It’s been updated.

Rob talks to Peter Brannen, author of the new book The Story of CO2 Is the Story of Everything.
How did life first form on Earth? What does entropy have to do with the origins of mammalian life — or the creation of the modern economy? And what chemical process do people, insects, Volkswagens, and coal power plants all share?
On this week’s episode of Shift Key, Rob chats with Peter Brannen, the author of a new history of the planet, The Story of CO2 Is the Story of Everything. The book weaves together a single narrative from the Big Bang to the Permian explosion to the oil-devouring economy of today by means of a single common thread: CO2, the same molecule now threatening our continued flourishing.
Brannen is a contributing writer at The Atlantic and the author of The Ends of the World, a history of mass extinctions on Earth. He is an affiliate at the Institute of Arctic and Alpine Research at the University of Colorado, Boulder. Shift Key is hosted by Robinson Meyer, the founding executive editor of Heatmap, and Jesse Jenkins, a professor of energy systems engineering at Princeton University. Jesse is off this week.

Here is an excerpt from our conversation:
Robinson Meyer: Why do we have a surplus of oxygen in the air in the first place? It was, for me, also something I did not understand at all before I read the book.
Peter Brannen: So there’s this common trope that two out of the next three breaths you have is from phytoplankton the ocean, or a quarter of it is from the Amazon alive today. And there’s a sense in which that’s true because oxygen and CO2 are being exchanged very quickly in the biosphere. But there is something like 800 times more oxygen in the air than can be produced by the entire biosphere. And all of the oxygen that’s produced by the rainforest, say — the rainforest is a living system where everything else is consuming that organic matter and feeding off of it. And it’s kind of a wash — just as much oxygen is created by the trees as is consumed by the bugs and fungi and jaguars and all the things that are living in the rainforest that are feeding off those plants and respiring that plant matter back to things like CO2 and water. So on a net scale it’s a wash.
So that gets you a planet with close to zero oxygen, and instead we have this absurd abundance of this thing that wants to react with everything. And the only way you can do that is if, say, you imagine a tree and when it dies, rather than being decomposed by fungi and beetles and on and on, that tree suddenly gets buried in sediment and falls into the crust and becomes part of the rock record, and the oxygen it made in life is not used in its own destruction. And by shielding that tree in the earth, you leave this surplus of oxygen in the air. And over all of Earth history, as a vanishingly small amount of this organic matter, things like plants and algae, do make it into the rock record, they leave an equivalent gift of oxygen in the air as a surplus.
We are more familiar with plant matter in the crust where it’s economically exploitable — we call those fossil fuels. So in a weird way, the fact that me and you can breathe — I don’t think a lot of people attribute that to the fact that there’s fossil fuels in the ground. Luckily most, you know, quote-unquote fossil fuels are very diffuse in mudstones, and they’re not economically exploitable. And we’re never going to run out of oxygen by burning fossil fuels because, you know, we worry about CO2 going up in parts per million and oxygens in whole percent. So, you know, it is true that for every molecule of CO2 we burn we’re bringing down oxygen by an equivalent amount, it’s just not that concerning.
But yeah, there is this astounding way of reframing, of looking at the world where the plant surface is breathable only because of what’s happened in the rocks beneath it.

Is the “turbine crisis” coming to an end? Or at least the end of the beginning?
One of the few bright spots for renewables this year has been that their main competitor for energy generation, natural gas, has been in a manufacturing crunch. An inability (or unwillingness) to ramp up production of turbines, the core component of a gas-fired power plant, to meet rising energy demand is cited regularly by industry executives and financiers to explain why renewables are the best solution to quickly getting power. And it’s reflected in the data; planned additions to the grid are overwhelmingly solar and storage.
But now there might be more turbines coming. Mitsubishi Heavy Industry chief executive Eisaku Ito told Bloomberg over the weekend that it aims to double its capacity to build gas turbines over the next two years.
The industry is essentially an oligopoly of three suppliers: Mitsubishi, GE Vernova, and Siemens Energy. Due to the high level of capital investment necessary to build turbines, there’s little chance of the triumvirate expanding. This means it’s a seller’s market. Developers describe having to be vetted by their suppliers for a product that might get delivered in five years, instead of suppliers fiercely competing for new business. That means for the turbine crisis to be truly reversed, executives (and investors) at Mitsubishi’s two competitors will have to be convinced that large-scale capacity expansions are worth it.
Something that might help them reach that conclusion is if capacity expansion plans are met with a higher stock price. In another ominous development for the renewable energy industry, Mitsubishi’s stock price went up in response to the news. Renewable developers have enough problems on their hands without having to worry about a gas turbine industry that could supply more and more megawatts over the medium term.
Gas turbine manufacturers have been trying to navigate the tension of fulfilling orders for new gas turbines and avoiding costly investments in new capacity that might not actually be utilized should the AI boom peter out, let alone if public policy makes it much more difficult to build new fossil-powered generation.
Up until now, manufacturers — and their investors — have seemed content with heavy demand and constrained supply. Going into the weekend, the stock prices of the gas turbine industry powerhouses GE Vernova, Siemens, and Mitsubishi Heavy Industry had risen 86%, 79%, and 69% so far this year.
But Mitsubishi Heavy Industry’s stock bump on Tuesday indicates that investors are not completely averse to capacity expansion. Yet at the same time, executives across the industry are careful to portray themselves as thoughtful and prudent stewards of capital.
Ito emphasized that the planned capacity expansion would not mean reckless investments, telling Bloomberg “the goal is to be as lean as possible” and that there would be work on the efficiency of the production process to address spiraling costs of turbine manufacturing.
“The executives seem keen to stress that this expansion will be lean and efficient,” Advait Arun, a climate and infrastructure analyst at the Center for Public Enterprise and the author of a much-cited Heatmap article on the turbine shortage, told me. “There’s a tension between getting over their skis by expanding overmuch while also killing the goose that’s laying their golden egg by not expanding.”
The pressure to build is immense — but so is the industry’s hard-won reticence about expansion.
Gas turbine orders are likely to hit a new record this year, according to S&P Global Commodities Insights, and the industry might be unwilling to go further.
“Past boom-and-bust cycles have made the industry cautious in its investments, and turbine demand in the early 2030s is uncertain,” S&P analysts wrote.
Siemens Energy chief executive Christian Bruch had told Morgan Stanley analysts in a note released Tuesday that the company had “no intention” of increasing capacity beyond working to expand the facilities it already has. He also said the company’s constraints are its own supply chain issues, namely the blades and vanes used in the turbines
And GE Vernova has been practically bragging about how far back they have reservations for turbines. “Our pipeline of activity for gas demand is only growing, but it is growing at even more healthy levels for 2029 deliveries, 2030, 2031,” the company’s chief executive Scott Strazik said on an earnings call in July.
And Wall Street has been happy to see developers get in line for whatever turbines can be made from the industry’s existing facilities. But what happens when the pressure to build doesn’t come from customers but from competitors?
A federal appeals court on Tuesday cleared the way for the Trump administration to kill former President Biden’s $20 billion green bank program, which would have provided low-cost loans for solar installations, building efficiency upgrades, and other local efforts to reduce greenhouse gas emissions.
The three-judge panel overturned a lower court’s injunction temporarily requiring the Environmental Protection Agency to resume payments, and ruled that most of the plaintiffs’ claims were contract disputes and belonged in the Court of Federal Claims. If the case now moves to the Court of Federal Claims, the plaintiffs would only be able to sue for damages and any possibility of reinstating the grants would be gone. But they could also petition to appeal the decision.
Congress created the grants, known as the Greenhouse Gas Reduction Fund, as part of the Inflation Reduction Act in 2022. It authorized Biden’s EPA to award $20 billion to a handful of nonprofits that would then offer financing to individuals and organizations for emission-reduction projects, mostly geared toward low-income or otherwise disadvantaged communities. The agency fully obligated the funds last August to eight nonprofits that would “create a national financing network for clean energy and climate solutions across the country.”
Then Trump took office and ordered his agency heads to pause and review all funding for Inflation Reduction Act programs. EPA Secretary Lee Zeldin targeted the Greenhouse Gas Reduction Program for termination, making a big show of a covert recording of a former agency employee comparing Biden’s efforts to get climate money out the door after the election to “throwing gold bars off the edge” of the Titanic. Nevermind that this particular program had been fully obligated prior to the election, and recipients had already started to announce investments as early as October.
The nonprofit awardees sued the Trump administration, and the District Court for the District of Columbia issued a temporary injunction on the EPA’s grant terminations in mid-April, mandating that the funds continue to be paid out while the case proceeded. The EPA appealed that injunction, leading to today’s ruling.
In her opinion for the majority, appeals court Judge Neomi Rao, a Trump appointee, dismissed the nonprofits’ claims that the EPA’s grant terminations were arbitrary and capricious, in violation of the Administrative Procedures Act. She wrote that the dispute was “essentially contractual” and therefore did not belong in the district court to begin with. The nonprofits had also alleged that the EPA violated the constitution's separation of powers in attempting to cancel the grant agreements, as Congress had given explicit direction to the agency to award the funds by September 2024. While Judge Rao allowed that the district court had jurisdiction over this particular claim, she ruled that it was “unlikely to succeed” on the merits.
This decision, if it stands, means the case is basically over, David Super, an administrative law expert at Georgetown Law, told me. The plaintiffs could ask to have it transferred to the Court of Federal Claims if they wish to pursue monetary damages, but that’s likely a losing proposition since Judge Rao — unusually, according to Super — went on to opine that the plaintiffs would have no case there, either.
The plaintiffs could, however, ask for a rehearing by the full D.C. circuit. “Given that this is a very important case, both legally and practically, I think they would have a good chance of getting reheard,” Super said.
There was one other important point in the decision. While this case has been playing out, Congress rescinded any “unobligated” funding — money that hasn’t yet been spent or contracted out — from the Greenhouse Gas Reduction Fund as part of Trump’s tax and spending law. The Congressional Budget Office estimated that the remaining balance in the fund was just $19 million, essentially the cost of program administration. But the Trump administration has argued in the ongoing court case that the law rescinded the full $20 billion. Judge Rao disagreed, writing that the law “did not render this appeal moot.”
This is the latest in a series of wins for the Trump administration over the termination of grant funding. Last week, the D.C. district court dismissed a challenge brought by nonprofits over the termination of the Environmental and Climate Justice Block Grants, another Inflation Reduction Act program, on the grounds that it belonged in the Court of Federal Claims. The Supreme Court also issued a similar opinion in August regarding grant funding from the National Institutes of Health that was terminated on the grounds of a shift in agency priorities.
The evaporation of $20 billion in clean energy funding is no small loss, but Super said the consequences could also be much more systemic, threatening the viability of federal grantmaking as a tool to stimulate private capital. “If these commitments are utterly unenforceable, then no one's going to do business with the federal government,” he said.
