Range Energy’s electric trailer, which can “electrify” a diesel semi truck just by adding a trailer, has been found to improve efficiency by 36% in independent testing.

We covered Range Energy’s trailer back in May when we saw it at ACT Expo, the largest expo for advanced fleets.

As a quick refresher, the basic idea is that the trailer has a battery and motors in it and can sense acceleration through the trailer’s kingpin. When the tractor pulls forward, the motors kick in to help carry the load, meaning the tractor doesn’t have to do as much pulling.

This means that a truck can be “electrified” without having to modify the truck at all – just attach a Range trailer with built-in electric propulsion and you’ve effectively turned a diesel tractor into a plug-in hybrid of sorts. Or, attach it to an electric tractor and you can extend range as well.

We had a demo of a dummy trailer at ACT Expo and frankly, it was the coolest demo I’ve ever had at a media event. I went from having a hard time pulling the trailer to being able to do it with one finger, and it was responsive enough that I really just felt like Superman.

Now, Range has undergone independent testing on its trailer to validate its efficiency claims, finding a 36% improvement (+3.25mpg, based on a 9mpg baseline). This was done on a 25-mile urban/high loop at 60mph top speeds and approximately 59k gross vehicle weight (so about half of the maximum trailer weight).

Testing was done by Mesilla Valley Transportation Solutions, a fuel economy consultant for the trucking industry which has validated many technologies, most of which give single-digit percent efficiency gains.

So, 36% is a pretty huge improvement compared to all of those. Which makes sense – none of the other technologies tested provide their own propulsion, just aerodynamic improvements.

​“We were impressed with the Range trailer. Whether a fleet wants to reduce fuel usage or increase BEV range, this system provides unique opportunities over a traditional trailer – and by a large amount when considering it achieved 36.3% fuel savings. Our drivers also liked the Range trailer; reporting it pulled easier and felt lighter. Naturally, there is a trade-off with electric charging and additional weight so it may not suit every fleet but for those considering the EV direction, Range is worth talking to.”

Daryl Bear, COO, MVT Solutions.

MVT used a diesel tractor, so we don’t know if the same improvements would happen for an electric truck – they would likely be close, but given that the electric truck already has regenerative braking, range gains might be a little lower than the 36% diesel efficiency gains.

Range Energy isn’t the only company doing something similar. Since we saw the Range trailer, we also heard about BMW doing the same thing in Europe with a trailer by Trailer Dynamics. Their solution has a much larger battery and claims higher efficiency gains, but it’s hard to compare the gains directly given the differences in testing regimens, regional shipping patterns and so on.

Range’s solution is not yet commercially available, but claims that production will ramp starting next year.

Electrek’s Take

The one issue with these tests is that the press release includes the words “up to” when describing the gains, and those words may be doing some heavy lifting. We’re curious to hear what circumstances work better or worse for the trailer, and what kind of average real-world gains can be gotten across a variety of fleets.

Other than that, I really like Range’s solution, because even though it doesn’t necessarily make trucks “all-electric” right off the bat, it does offer a much faster and easier way to electrify for many fleets.

Electric trucks are still quite expensive upfront, and while they offer extremely impressive benefits in terms of running costs, smaller operators can have a hard time fronting the money to convert to electric. While Range’s solution will certainly not be cheap either, it may offer an easier way to improve a fleet’s efficiency quickly.

My worry is that the market for Range’s solution will disappear over time. There is a lot of potential market to quickly electrify diesel tractors by adding a trailer, but as more and more electric trucks become available, there will be less and less need for Range’s trailer.

The “range extending” function might still be useful in some circumstances (e.g. medium-to-long-haul electric trucking of low weight and high volume items), but it still seems like a transitional solution rather than a permanent one. Especially with the rapid shift to electrification coming in trucking, led by California’s strong new trucking regulations.

So, Range just has to get to market and ramp up quick, both because it will offer immediate efficiency and clean air gains, and because the business might only have a limited time before it loses some of its relevance while electric trucks start to take over the industry.

Total ‘pauses’ New York offshore wind project after Trump win

Total 'pauses' New York offshore wind project after Trump win

After Donald Trump’s US election win, French energy giant TotalEnergies has hit the pause button on Attentive Energy, its planned offshore wind farm off the New York coast.

“Offshore wind, I have decided to put the [Attentive Energy] project on pause” with Trump’s return, said Total CEO Patrick Pouyanne on Tuesday at an energy conference in London. “I said to my team, the project in New York, we’ll see that in four years. But the advantage is it’s only for four years.”

Total’s offshore wind project is Attentive Energy, which is an 84,332-acre area around 54 miles from its nearest point to New York and 42 miles from its nearest point to New Jersey. Attentive Energy has the potential to generate 3,000 MW of clean energy to power nearly 1 million homes.

The company won the rights to develop Attentive Energy in a record-setting auction in 2022 and planned to bring it online in the early 2030s. But the project is currently in a very early phase, and it’s not permitted. It hasn’t filed a construction and operations plan with the US Department of the Interior, and that review process can take at least three years, which would be particularly challenging, if not impossible, under an administration that openly opposes the offshore wind industry.

Trump is a vocal critic of offshore wind and has repeatedly vowed on the campaign trail to target the industry with an executive order on his first day in office. His plans are vague but probably relate to lease sales and permitting. He’s also chosen pro-fossil fuel fracking executive Chris Wright as secretary of energy.

However, Trump won’t be able to cancel offshore wind farms that are fully permitted and are at more advanced construction stages.

Total is retaining Attentive Energy’s lease so it can resume work on the offshore wind project after Trump’s term ends under a more environmentally friendly administration.

EV sales are set to surge as buyers rush to claim discounts that may disappear in 2025

EV sales are set to surge as buyers rush to claim discounts that may disappear in 2025

With US President-Elect Trump reportedly planning to cut federal incentives, EV sales are expected to surge in November and December. Right now, major discounts are slashing upwards of $10,000 to $20,000 off some of the most popular EV models, but that could change in 2025.

EV sales are expected to surge with discounts on the line

According to Cox Automotive, “EV sales are expected to surge in November and December” ahead of Trump taking office.

“We may see an increase in electric vehicle (EV) and plug-in hybrid (PHEV) sales over the next few months as buyers move to take advantage of discounts that may disappear in 2025,” Charlie Chesbrough, senior economist at Cox Automotive, said.

A Reuters report earlier this month claimed Trump’s transition team was planning to kill off the $7,500 federal tax credit for clean car buyers.

Chesbrough explained that with fewer discounts on the line, buyers are expected to take advantage of them while they are still being offered, leading to “robust activity through the end of the year.”

In October, EV sales in the US reached a milestone. With another 106,155 units sold last month, over 1 million EVs have now been handed over to buyers.

EV lease deals are adding up

Higher incentives and discounts have helped fuel the growth. In Q3, EV incentives were over 12% of the vehicle’s average transaction price, much higher than the industry average of about 7%.

The $7,500 federal tax credit is the biggest factor behind the discounts. Although the credit is for EV purchases, a loophole enables automakers to pass it on through leasing.

Combined with other offers like loyalty and conquest, lease discounts, and bonus cash, some EV discounts are reaching upwards of $10,000 to even $20,000.

For example, you can score up to $21,150 off the 2024 Acura ZDX luxury SUV with combined discount offers. Ford is also offering up to $17,500 off its F-150 Lightning pickup through an end-of-year promo. A few EVs are even available to lease for under $300 this month.

Lease From Term
(months)
Due at Signing Effective rate per month
(including upfront fees)
2024 Nissan LEAF $109 36 $2,529 $179
2024 Kia Niro EV $169 24 $3,999 $336
2024 Kia EV6 $179 24 $3,999 $346
2024 VinFast VF 8 $199 36 $894 $244
2024 Hyundai IONIQ 5 $199 24 $3,999 $366
2024 Honda Prologue $229 36 $1,299 $259
EVs for lease under $300 per month in November 2024

Several new lower-priced models, like the $35,000 Chevy Equinox EV LT and Honda Prologue, are also hitting the market. The electric Equinox and Prologue SUVs helped push EV incentives to a record high in October.

With the $7,500 credit, the 2025 Chevrolet Equinox EV can be bought for as little as $26,100. GM calls the new electric SUV “America’s most affordable 315+ mile range EV.”

Honda just extended its ultra-low $229 per month lease offer to 17 additional US states after introducing it in California last month. For a nearly $50,000 electric SUV, $229 per month (36 months, 10,000 miles per year) is a pretty good deal.

Tesla adds direct charge port defrosting option just in time for winter

Tesla adds direct charge port defrosting option just in time for winter

Tesla adds direct charge port defrosting option just in time for winter

During Model 3’s first winter in 2018, we reported that the electric car had some issues with the cold weather, and Tesla said they were investigating the situation.

Several owners in cold weather regions were experiencing difficulties entering their vehicles because the door handles wouldn’t open, the windows, which need to go down about an inch to open the doors, would jam, and even the charge port would freeze shut.

A week later, Tesla released a software update to help with some of these issues.

Later, they also released a new software update to use climate control to help thaw the charge port when it gets frozen.

However, the real solution to the freezing charge port was a heater dedicated to it, which Tesla started putting in its vehicles in late 2020.

While charge port heaters have been in vehicles for years, Tesla never really gave the option to owners to specifically defrost their charge ports. Instead, it would activate when turning on the overall or rear defrosting functions of the vehicles.

This is now changing.

Not A Tesla App, which tracks Tesla software updates, is nothing that some Tesla vehicles are now getting the specific option to activate the charge port heater with the latest software update:

Tesla has finally added a solution to this problem. You can now manually turn on the charge port heater by going to Controls > Service > Charge Port Heater. However, the feature is not available on all vehicles. It’s only appearing in the release notes for a very small segment of vehicles. We’ve confirmed that it is showing up on a 2024 Model X and some 2023 Model Ys on Tesla software update 2024.44.3.1.

The change is coming right in time for the cold weather, and it should enable owners to target the charge port when needed – increasing efficiency.

Electrek’s Take

To be honest, I haven’t heard many issues about frozen charge ports since the first winter with the Model 3. I had this issue myself during the first winter.

There were a few reports about it the next two winters, but Tesla did help a lot simply with a software update to better manage the airflow toward the charge port area. Then, when the heater was introduced, it seemed to have basically eliminated the issue.

I still like to have a direct option to activate the specific charge port heater. It makes sense.
