Data from real-world testing involving 99 cars — half Tesla Model 3s and half Nissan Leafs — found that the Leaf was more efficient on average than the Model 3.
According to research done by Recurrent, an EV testing and analysis firm, 500,000 data points of efficiency metrics logged between November of last year and March of this year, representing roughly equal groups of Tesla Model 3s and Nissan Leafs, highlighted a strange occurrence. The Leaf group was more efficient on average than the Model 3 group — 3.7 miles per kWh compared to 3.4 miles per kWh.
Before looking at Recurrent’s results, it is important to recognize that the Model 3 is, according to multiple metrics and measuring groups, considered as one of the most efficient vehicles. According to FuelEconomy.gov, their “MPGe” (miles per gallon equivalent) metric lists the Model 3 Standard Range Plus RWD as the most efficient vehicle in their database, scoring 142 mpge. In comparison, the 2021 Hyundai Ioniq Electric scored 133 mpge, the Lucid Air 131 mpge, and the newest model Leaf 111 mpge.
Another similar study done by the American Council for an Energy-Efficient Economy (ACEEE) found that the Model 3 used some of the least energy per 100 miles compared to a variety of rivals.
Despite these data points, Recurrent notes that the Nissan leaf proved to be the more efficient vehicle, even in adverse weather conditions. Further, older model year Nissan leafs achieved higher efficiency in most weather conditions compared to their newer counterparts.
So what could have accounted for the Leaf group achieving such high levels of efficiency? Recurrent points to driver behavior as the driving factor. Nissan drivers must maximize the range that their vehicle is capable of, which is often a fairly limited total range. Recurrent says drivers are incentivized to drive more cautiously.
On the other hand, Tesla drivers may drive more “regularly”; using air conditioning, accelerating quickly, etc. Each of these factors drives down the efficiency of the Tesla vehicles.
On top of this, Recurrent says “Nissan drivers see their cars as an extension of their values. This means they are more likely to pay attention to their efficiency and alter their preferences to maximize it.”
The main takeaway should not be that Tesla has not designed an efficient vehicle, nor should it be said that Nissan (while performing admirably) has designed an incredibly efficient vehicle. The clear trend is that driver action, much like in ICE vehicles, is one of the predominant factors determining the efficiency of a vehicle.
A few questions remain nonetheless; should manufacturers be incentivizing more efficient driving, or should the primary goal be to offer the best overall experience to drivers? And as EVs become more common, will focus switch from range or charging speed to efficiency?

Tesla revamped Semi spotted, insane 1.2 MW charging video releases
These developments highlight Tesla’s ongoing refinements to the vehicle’s design and infrastructure.
Tesla is gearing up for high-volume Semi production in 2026, with the Class 8 all-electric truck’s revamped variant being spotted in the wild recently. Official footage from Tesla also showed the Semi achieving an impressive 1.2 MW charging rate on a charger.
These developments highlight Tesla’s ongoing refinements to the vehicle’s design and infrastructure.
Revamped Tesla Semi sighting
Tesla Semi advocate @HinrichsZane, who has been chronicling the progress of the vehicle’s Nevada factory, recently captured exclusive drone footage of the refreshed Class 8 truck at a Megacharger stall near Giga Nevada. The white unit features a full-width front light bar similar to the Model Y and the Cybercab, shorter side windows, a cleared fairing area likely for an additional camera, and diamond plate traction strips on the steps.
Overall, the revamped Semi looks ready for production and release. The sighting marks one of the first real-life views of the Class 8 all-electric truck’s updated design, with most improvements, such as potential 4680 cells and enhanced internals, being hidden from view.
1.2 MW charging speed and a new connector
The official Tesla Semi account on X also shared an official video of Tesla engineers hitting 1.2 MW sustained charging on a Megacharger, demonstrating the vehicle’s capability for extremely rapid charging. Tesla Semi program lead Dan Priestley confirmed in a later post on X that the test occurred at a dedicated site, noting that chargers at the Semi factory in Nevada are also 1.2 MW capable.
The short video featured a revamped design for the Semi’s charging port, which seems more sleek and akin to the NACS port found in Tesla’s other vehicles. It also showed the Tesla engineers cheering as the vehicle achieved 1.2 MW during its charging session. Dan Priestley explained the Semi’s updated charging plug in a post on X.
“The connector on the prior Semi was an early version (v2.4) of MCS. Not ‘proprietary’ as anyone could have used it. We couldn’t wait for final design to have >1MW capability, so we ran with what had been developed thus far. New Semi has latest MCS that is set to be standard,” the executive wrote in a post on X.

Tesla FSD successfully completes full coast-to-coast drive with zero interventions
Tesla community members celebrated the milestone on X, and the feat earned praise from some of the electric vehicle maker’s executives.
A Tesla owner has successfully completed a full coast-to-coast drive across the United States on Full Self-Driving (FSD) Supervised. The trip was accomplished with zero interventions.
Tesla community members celebrated the milestone on X, and the feat earned praise from some of the electric vehicle maker’s executives.
FSD Coast-to-Coast
The coast-to-coast feat was accomplished by Tesla owner Davis Moss, who drives a stealth gray Model 3 with AI4 hardware. Based on data from the FSD database and a community tracker, the last 10,638.8 miles Moss drove in his Model 3 were completed using FSD 100% of the time. His vehicle is equipped with FSD v14.2.1.25, which was installed 12 days ago.
As per Moss in a celebratory post on X, his Model 3 was able to complete a full coast-to-coast drive across the United States in 2 days and 20 hours. His trip started at the Tesla Diner in Los Angeles, CA, and it ended in Myrtle Beach, SC. Overall, his trip spanned 2,732.4 miles.
“This was accomplished with Tesla FSD V14.2 with absolutely 0 disengagements of any kind even for all parking including at Tesla Superchargers,” Moss stated in his post. He also added in later comments that there were zero close calls during the trip.
Tesla community celebrates
The FSD milestone trip was widely lauded by members of the Tesla community, especially since a coast-to-coast drive with zero interventions has been cited by Elon Musk as a target since October 2016, when Autopilot 2.0 was unveiled. At the time, Musk initially estimated that a coast-to-coast drive across the United States should be possible by the end of 2017. Considering Moss’ feat in his Model 3, it appears that Elon Musk’s estimate was not impossible at all. It was just late.
Musk himself celebrated the milestone on X, and so did Tesla VP of AI Software Ashok Elluswamy, who wrote “World’s first fully autonomous coast-to-coast drive, done with Tesla self-driving v14. Congrats and thank you @DavidMoss!” in a post on X. The official Tesla North America account also celebrated the feat, writing “First Tesla to drive itself from coast to coast w/ FSD Supervised. 0 interventions, all FSD” on X.

Elon Musk: Tesla Model Y is world’s best-selling car for 3rd year in a row
The Model Y has now established an impressive streak that would otherwise have been impossible before Tesla.
Elon Musk has announced that the Tesla Model Y has become the world’s best-selling car by volume for the third consecutive year, capping 2025 with another dominant performance.
The Model Y has now established an impressive streak that would otherwise have been impossible before Tesla.
Three years in a row
Musk posted on X: “Tesla Model Y is now officially the world’s best-selling car for the third year in a row!” The CEO’s comment echoed an update that Tesla included in its 2025 recap, which highlighted, among other things, the Model Y’s incredible streak.
The Model Y has held the title since 2023, outperforming traditional leaders like the Toyota RAV4 and Corolla thanks to its bang-for-the-buck nature and its stellar combination of practicality, performance, and tech. The Model Y is also lauded as one of the safest vehicles on the road, making it an ideal choice for families in key markets such as China.
An impressive 2025
The Model Y’s sales feat in 2025 is especially impressive considering the introduction of the vehicle’s new variant. Tesla’s changeover to the new Model Y across its global factories resulted in sales being paused for some time in the first quarter. As per Tesla’s Q1 2025 vehicle delivery and production report, “the changeover of Model Y lines across all four of our factories led to the loss of several weeks of production in Q1.”
This suggests that the Model Y’s sales remained strong in 2025 to the point where it could still claim the title of the world’s best-selling vehicle by volume, even with its sales being throttled during the first quarter of the year. It would then be interesting to see just how far the Model Y can go in 2026, especially considering the rollout of new variants like the six-seat extended wheelbase Model Y L, the affordable Model Y Standard, and the top-tier Model Y Performance.
