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 launches Powerwall Lease for affordable home backup
Tesla Energy has introduced the Powerwall Lease in conjunction with Tesla Electric, making the service available in Texas. This new option delivers whole-home backup power using two Powerwall units for a net monthly cost of $35 after credits, accompanied by a low fixed electricity rate.
Under the lease terms, customers pay a one-time order fee of $100. The base lease payment for the two Powerwalls is approximately $122 per month during the first year, subject to a 3 percent annual escalator thereafter. Enrollment in a qualifying Tesla Electric Backup plan or Virtual Power Plant plan provides an $87 monthly credit.

This credit lowers the effective cost to roughly $35 per month plus applicable tax.
Installation of the standard system carries no additional charge. The package features Storm Watch for outage protection and allows complete management through a single Tesla application. The system supplies continuous whole-home backup capability.
The Powerwall system enables households to maintain electricity during severe storms that disrupt the utility grid. When outages occur, the batteries automatically provide seamless backup power to the home.
Tesla announces 100k Powerwalls are participating in Virtual Power Plants
Tesla Storm Watch monitors weather forecasts and ensures the units are fully charged ahead of anticipated severe weather events so that power remains available throughout the disruption, keeping lights, refrigeration, and other essential systems operating without interruption.
Availability is restricted to select Texas locations where retail electric choice exists. Participants must lease exactly two Powerwall units and maintain continuous enrollment with Tesla Electric. Solar panels cannot be included under this particular lease arrangement.
The monthly credit activates automatically once the system is installed, receives permission to operate, and enrollment is confirmed. To retain the credit, customers are required to stay enrolled in Tesla Electric and fulfill all program conditions.
Nonstandard installations that involve electrical upgrades or special permitting may lead to extra expenses and might impact eligibility for the credit, so be sure to check with either your installer or Tesla to ensure you will still qualify.

Elon Musk teases Tesla Roadster unveiling once again
Elon Musk continues to tease the unveiling event for the Tesla Roadster, a continuing trend that has grown into a bigger game of “When” for fans who have been waiting years for the car to finally enter production.
A video shared on X of the Joe Rogan Experience podcast that Musk appeared on last year, teasing the Roadster unveiling, was shared once again on the social media platform. The poster said the Roadster event will be “unforgettable.”
Musk agreed:
Yes
— Elon Musk (@elonmusk) August 12, 2026
The timing is interesting because just yesterday, Musk said that we will be getting flying cars, and for years, Tesla has hinted that it could develop a SpaceX cold gas thruster package that would help the car float or fly for a short period of time.
It would be reasonable to assume Tesla’s major delays with this unveiling event are likely caused by the company’s need to break the rules and push the envelope on nearly everything. Last July, Lars Moravy, Tesla’s VP of Vehicle Engineering, said:
“Roadster is definitely in development. We did talk about it last Sunday night. We are gearing up for a super cool demo. It’s going to be mind blowing. We showed Elon some cool demos last week of the tech we’ve been working on and he got a little excited.”
The latest updates that Tesla has given us are that the Roadster is in design development, and it did have several potential dates for an unveiling event this year, including April. It was then pushed to August.
However, there are no clues as to when Tesla will be ready, and fans are certainly getting frustrated with the delays.
For what it is worth, Franz von Holzhausen told Jay Leno this week that the event would be “very soon.”
We sure hope.

Tesla’s driverless Cybercab just passed a big test with State Governor
Florida’s governor rode Tesla’s Cybercab at a closed test track and called the experience impressive.
Florida Governor Ron DeSantis rode in a Tesla Cybercab on a closed test track this week and came away impressed, posting on X that the vehicle “successfully navigated all hazards — a kid running into the street, a crash with police stopping traffic, a Model S cutting us off, etc.” He called the ride “impressive.”
The stop was part of a broader event Monday at SunTrax, a 775 acre state owned proving ground in Auburndale that Florida built specifically to test autonomous and connected vehicles before they reach public roads. Standing next to a gold Cybercab, DeSantis described the car in plain terms: “You go in there and you just sit. You have a screen. There’s no steering wheel, no pedals. Clearly these things could be very beneficial.”

— Ron DeSantis (@RonDeSantis) August 11, 2026
DeSantis paired the praise with a caveat that has followed autonomous vehicles since the category existed. “You don’t want to be in an autonomous vehicle and it drives you into a ditch. That would not be good,” he said, framing safety validation as the gate before wider deployment.
SunTrax, the 2.25 mile oval which the state calls the only high speed autonomous vehicle test track in the Southeast, can simulate rain, pedestrian crossings, hills and crowded urban conditions at highway speeds, letting companies push a car past what an early public rollout would risk. Tesla, Waymo and Beep all use the facility, and Florida’s regulatory approach, among the most permissive for autonomous vehicles in the country, doesn’t require a human operator inside a fully autonomous car.
Tesla has reason to want the blessing of Florida and states beyond, as the Cybercab entered volume production at Gigafactory Texas this spring and has since self certified as SAE Level 4 under Texas law. Public road testing so far has kept a safety monitor in the passenger seat, and Florida is where Tesla has been expanding its existing Model Y based Robotaxi service instead, adding Miami in July and then Orlando and Tampa two weeks later. A closed track endorsement from a sitting governor doesn’t change any of that, but it does put Tesla’s newest hardware in front of a state that has already shown it will move fast on rules.
