• Modern EVs don’t suffer the extreme-temp range loss—or degradation—that earlier models did
• Heat pumps and battery heaters have made a difference, as have new battery chemistries
• Automaker testing is part of it, as Nissan points to in Ariya EV

Electric vehicle batteries perform best and last longest in a specific temperature window, but modern EVs are still equipped to deal with temperatures much hotter or colder than that ideal.

As Nissan explained in a recent press release, that’s largely down to equipping vehicles with thermal-management hardware—and validating that hardware with thorough testing.

The Nissan Ariya crossover uses liquid cooling to keep its battery pack at the optimal temperature during hot weather, and a battery heater in colder temperatures. The Ariya also has a heat pump to minimize cold-weather range loss—something the popular Tesla Model Y and Model 3 also have.

Nissan Ariya cold temperature testing

Like most other major automakers, Nissan tests new vehicles in climate-controlled chambers to monitor extreme temperatures. Such a chamber at Nissan’s Detroit-area technical center is capable of temperatures ranging from -40 degrees Fahrenheit to 176 degrees Fahrenheit, the automaker claims.

In a 24-hour “cold soak” test conducted in 2024, an Ariya was parked in the chamber with a 17% charge at -4 degrees Fahrenheit. After a full day had passed at that temperature, without the car being plugged in or using its battery heater, Nissan claims the charge level was unchanged.

Owners might want to leave a car plugged in, of course, both to charge and to pre-heat the cabin without drawing down the pack. Since they’re not waiting for the waste heat from a combustion engine, EVs inherently warm their interiors faster, too, Nissan notes.

Very high temps are a consideration nearly every automaker has allowed for in modern EV development, too. Nissan also uses Ariya SUVs for the security patrols at its proving ground near Phoenix, Arizona, to keep prying eyes away from new models circling test tracks out in the desert. In 2023, Nissan replaced gasoline Armada and Frontier patrol vehicles with a pair of Ariya EVs, which have since covered more than 30,000 miles at the site, where summer temperatures can exceed 115 degrees Fahrenheit. They’re part of a fleet of 10 Ariyas at the facility.

This more thorough testing in extreme temperatures—and wider use of heat pumps and other related hardware—appears to be paying off. Recurrent, which gathers EV driving data to compile battery health reports for used vehicles, found that 20 popular models are now averaging 80% of peak range in freezing temperatures, compared to ideal conditions. That’s based on data from over 18,000 vehicles in the U.S., according to Recurrent. 

As with previous studies, Recurrent found that each model performs differently, but that all models surveyed can deliver over 100 miles of range when the thermometer needle drops below freezing. Yes, that even includes the base 149-mile Nissan Leaf. The heat pump-equipped Tesla Model X and Model S performed best, and heat pumps overall averaged a 10% improvement in cold-weather range.

Nissan itself is a good example here for how far EVs have come in adding thermal systems and accommodating for extremes. The original Nissan Leaf EV lacked active thermal management, and its first cells suffered from excessive range reduction in the cold and accelerated degradation from the heat. That was partly solved in 2015 with a new cell chemistry, but as it’s shown here all the advantages built into the Ariya may be worth their added complexity. 

It’s also important to remember that whatever range loss owners encounter in cold weather is temporary. Long-term battery degradation is accelerated in hot weather, although research done last year by Geotab suggests that for most new EVs, battery degradation shouldn’t really be a concern—even if you follow habits that had been frowned upon with earlier EVs, like frequent fast-charging.

Honda and Nissan on Thursday terminated a memorandum of understanding under which the two automakers had been discussing a merger, but plan to continue collaborating.

The memorandum was signed by the two automakers in December as the first step toward a merger targeted for 2026. The decision to terminate it comes after discussions by each automaker’s management team and various stakeholders that “considered the surrounding market environment, the objectives of the business integration, and the management strategies and structures post-integration,” a joint statement said.

When talks started, both automakers had discussed transferring their shares to a joint holding company, in which Honda would appoint the majority of directors and a CEO. But Honda later proposed making Nissan a subsidiary. A report earlier this month indicated that this was jeopardizing the planned merger. Such a structure would diminish Nissan’s decision-making authority, and had reportedly caused the automaker to withdraw from negotiations.

Both companies agreed to cease merger talks in order to “prioritize speed of decision making and execution of management measures in an increasingly volatile market environment heading into the era of electrification,” the statement said. But the two automakers will continue working together.

“Nissan and Honda will collaborate within the framework of a strategic partnership aimed at the era of intelligence and electrified vehicles,” the statement said. The automakers signed a memorandum of understanding for a strategic partnership covering EVs, hybrids, and software in March 2024 that will continue to move forward, Nissan indicated.

The merger would’ve been a lifeline for Nissan, which has been struggling with declining sales globally, particularly in the U.S. and China. Nissan also owns 34% of Mitsubishi, and the two automakers collaborate as part of an alliance with Renault, but Mitsubishi was reportedly planning to stay out of the proposed merger with Honda.

Stellantis is now taking orders for all three versions of the Ram ProMaster EV electric van family, with deliveries to begin in the second quarter of this year.

When it announced the ProMaster EV just over a year ago, Ram said it would be offered in a delivery van configuration and two cargo van options. The delivery van went on sale as a 2024 model; now the two cargo options are arriving for the 2025 model year.

The cargo models include a standard 12-foot cargo length with an extended 13-foot length optional, both with a 159-inch wheelbase. This front-wheel-drive van has a single electric motor producing 268 hp and 302 lb-ft of torque in both cargo models, as well as the delivery van.

2025 Ram ProMaster EV Cargo Van

A 110-kwh battery pack, below the center of the vehicle to maintain a flat cargo floor, delivers an estimated 164 miles of range in the cargo vans and 180 miles in the delivery van. Ram also claims a maximum payload of 3,020 pounds for cargo vans and 2,876 pounds for the delivery van, with volume unchanged versus equivalent internal-combustion models.

Prices start at $58,490 for the cargo models and $71,990 for the delivery van. That means the 2025 Ford E-Transit remains the lowest-priced electric van, at a starting price of $53,095. But at only slightly more for more range and battery flexibility, the ProMaster also appeals on value.

And it significantly undercuts the $82,900 base price of the Rivian Commercial Van 500 recently announced, with similar range. That van is similar in design to the one Rivian once sold exclusively to Amazon; following the end of that exclusivity deal, Rivian is now opening electric van sales to all fleets.

The Rivian is based on an EV-specific platform, but the ProMaster EV and gasoline ProMaster share underpinnings. That’s also the case for the Ford E-Transit and current Mercedes-Benz eSprinter—although a family of standalone Mercedes electric vans is on the way within two years. General Motors has also designed electric vans from scratch, even marketing them under the separate BrightDrop brand for some time, before folding it into Chevrolet.

• Bigger battery packs bring an inflated carbon footprint
• Solution is higher efficiency and reeling range in to a real-world 300 miles
• Six upcoming Neue Klasse EVs will follow this philosophy

BMW aims to grow its electric-vehicle momentum with its next-generation Neue Klasse family of vehicles, but it won’t be doing that with big battery packs.

“You can’t make battery packs bigger and bigger because then BEVs don’t make sense anymore,” BMW chief development officer Frank Weber said in an interview with Automotive News Europe published Monday, arguing that chasing ever-bigger range numbers with ever-larger battery packs would lead to a penalty in the form of an inflated carbon footprint.

Bigger battery packs could indeed lead to more emissions from their manufacture—plus a range of farther-reaching consequences. One 2022 study suggested heavier EVs would also mean increased particulate emissions from tires wearing down more quickly under the added weight of those packs. They’ll also strain the supply chain, which has been shown to be fragile over the past few years.

BMW Vision Neue Klasse concept

“Improving efficiency is much more important than ever-larger batteries,” Weber said. “And this is exactly what we are doing with the Neue Klasse, which makes efficiency leaps of up to 20%, depending on the model.”

At a certain point, increased range is also unnecessary, Weber said, noting that current BMW EV customers are happy with 250 to 310 miles of range “under real-world conditions.” BMW is finding that this amount of range allows customers to complete most trips without charging, Weber, said, adding that BMW still is aiming for a 30% range boost over its current models with the Neue Klasse.

Those comments echo what Green Car Reports and a rather small group of automakers have emphasized for years—that range is a red herring, and that no one needs a 500-mile EV. But now that philosophy is being applied to what BMW has promised will be a large family of fairly high-volume models.

Pre-production example of first BMW Neue Klasse electric vehicle at plant in Hungary

BMW plans to launch six Neue Klasse EVs within the next two years, Weber told Automotive News Europe. The first of those models, an electric crossover SUV, is expected to start production later this year. The first vehicles will be built in Hungary, but BMW has said factories in Germany and Mexico will build Neue Klasse models as well.

Those models will reverse BMW’s current trend of basing EVs on existing gasoline vehicles, although Weber pointed out that they’ll still share elements with other BMW models, such as the new dashboard display the automaker unveiled last month at CES 2025. During media roundtables at that show, Weber also said the upcoming EVs will set the design template for future gasoline BMW models.

Automakers are already preparing for the federal government stop electric vehicle tax incentives, lobbying for a gradual phaseout rather than an abrupt end, Bloomberg reported Tuesday.

Several automakers, including Ford and General Motors, along with industry lobbying groups, have asked the Trump Administration and Republican Congressional lawmakers to preserve some EV incentives from the Biden Administration’s Inflation Reduction Act (IRA) as long as possible, according to the report, which cites anonymous sources familiar with the matter.

The IRA, with its manufacturing incentives and tax credits, was predicted to double EV sales by 2030 vs. the previous forecast. But by all previous accounts, the Trump Administration was aiming to make nixing the federal EV tax credit a priority—with support from Elon Musk and Tesla.

According to this report, one of the ideas being discussed in the event that Trump eliminates it is a three-year credit sunset that would buy more time to reduce costs of new EVs and make the loss of the tax credit less impactful.

Automakers are reportedly also rallying to keep the so-called leasing loophole that allows automakers with captive financing companies to get a $7,500 tax credit for leased vehicles, and pass the savings on to the customer. This allows for an equivalent discount on EVs that wouldn’t normally qualify for the credit due to price, battery-materials sourcing, or the customer’s income.

2025 Ford F-150 Lightning

That led to a surge in EV leasing in recent years—with federal money subsidizing luxury EVs built in other countries. That’s likely not going to be a winning argument in Congress, where the IRA’s EV tax credit barely squeaked through the first time around.

Even if automakers fail to convince Republicans to keep the federal EV tax credit, increased state incentives may help make up for it. California plans to provide its residents with $7,500 rebates if Trump kills the tax credit, but it’s seeking to exclude Tesla, ostensibly to provide more incentives to brands with less market share in order to promote competition.

Although car companies typically want to push new models onto the public, in some cases they provide plenty of support for customers looking to hold onto and maintain a classic. This used to be the domain of exotic brands like Aston Martin and Ferrari, whose classic cars are often worth so much they’re typically seen as investments, but in recent…
