One Tesla Cybertruck owner who took delivery this week reported crazy driving efficiency, after notably receiving the electric vehicle (EV) with the new Core Wheels and aero wheel covers.
In a post on the Cybertruck Owners Club forum on Friday, user MadMaxTX shared photos of the newly delivered Cybertruck, adding that the drive home resulted in 304 wH/mile, equating to about 370 miles of range total. On the second drive, the user reported a consumption of 285 wH/mile, which would equate to about 400 miles of range.
“Driving home, consumption was 304 wh/mile! This is around 370 miles on a full charge, mixed city driving, about half freeways,” wrote the user. “Next trip, streets only, light traffic, 97 degrees, BTW, and 285 wh/mile which works out to about 400 miles range.”

The driver also questioned whether or not this could be expected regularly with the Tesla Cybertruck, or if the initial drives were simply some kind of fluke.
As can be seen in the user’s photo, the new Core Wheels come with the Pirelli Scorpion ATR tires, which were developed specifically for the Cybertruck and include the word “CYBRTRK” on their outer walls. Tesla launched the Core Wheels option just this week, coming as a more efficient alternative to the company’s normal Cyber wheels included on the dual-motor configuration.
On its website, Tesla estimates that the tri-motor Cyberbeast configuration is rated for up to 301 miles, while the dual-motor AWD trim is rated for about 318 miles of range. With the inclusion of the Core Wheels, which are only available with the AWD configuration, Tesla estimates around 340 miles of range total.
Following our story, Tesla Cybertruck Lead Engineer Wes Morrill also highlighted the fact that it shouldn’t come as too much of a surprise that all-season tires, which are included with the Core Wheels, are more efficient than all-terrains, which come with the Cyber Wheels option. Morrill notes that the tires included with the Core Wheels offer a “custom construction which balances handling and efficiency while also reducing road noise.”
He later responded to continued conversations in the X thread, providing a few more details on the all-terrain versus all-season tires discussion:
Typically All terrain > All-season in snow. That said, a 3-peak rated tire will be best in snow. Tesla will offer a 3-peak winter tire package on the shop for those looking for the best winter performance.

Cybertrucks have recently been spotted in the wild with the new Core Wheels and covers, along with one unit sporting the highly anticipated lightbar alongside the covers and wheels. Tesla also began offering Cybertruck demo drives at select locations in the U.S. and Canada, after launching the EV in the latter country to mark the first Cybertruck sales outside the U.S.

A Tesla Semi caught fire in Hayward, California, which caused both directions of traffic to shut down for hours before being completely reopened early on Wednesday, the California Highway Patrol said.
The fire occurred just after 5:30 local time in Hayward on Tuesday, as the Semi caught fire in the southbound lanes of I-880 before CHP officials made the decision to shut down both lanes of traffic due to potential risks from hazardous chemical smoke.
There were no injuries reported.

The cause of the fire is currently unknown, as neither Tesla nor the CHP have not determined a cause.
However, some images taken before the Semi was completely destroyed by the fire seem to indicate this might have been an older unit, as it appears to be one of the designs that Tesla shipped as part of its pilot program, before revising it and starting mass production just a month ago.
@Tslachan From on of the videos looks like it’s an old Semi (not the refresh version that recently started production) https://t.co/KzwmR2kXow

At the time of publication, CHP had not returned our request for a comment for additional details, including the Semi involved and any potential collaboration on an investigation between the CHP and Tesla. We will update this story when we hear back from them.
The southbound lanes were reopened at 3:30 a.m. on Wednesday, with the northbound lanes opening last night a few hours after the fire began. The CHP did state that the lithium batteries were “incredibly difficult to extinguish,” according to NBC Bay Area.
The truck’s driver said that the Semi caught fire, but he did not have an explanation.

Tesla’s launch of the “Emergency Drive Away” function a few months back offered owners a safe option to evacuate an area if they were in reasonable danger. The function finally got its first use in the real world, but it appears it was by mistake.
A video shared by u/Joshalander in the r/TeslaLounge subreddit recorded the instance from his vehicle and said the incident took place in Austin this past weekend during the city’s F1 Race.
“Was charging around 6 AM this past Sunday in Austin before heading to the F1 race and heard a pop. Looked over and saw the new emergency drive-away feature in action. Genuinely felt bad for the dude when he got out and realized what happened, since he looked exhausted and only seemed to half-read the prompts.”
🚨 Here’s the first look at Tesla’s Emergency Drive Away function in action:
Apparently this driver accidentally enabled it and drove forward; you can see the Supercharger pull with the car.
Tesla said previously this would cost up to $25k if not used properly. https://t.co/B4qQRrsO6B

Emergency Drive Away unlatches the Supercharger connector from the vehicle, but still causes damage to both the car and the Supercharger. Tesla has said that it will cost up to $25,000 in repairs to have everything fixed back to normal.
Additionally, the company said that if it were not used in an emergency situation, the driver of the vehicle who activated the Emergency Drive Away feature would be responsible for all repair costs.
Tesla constitutes the following situations as reasonable justifications for activating the feature:
- You face an immediate threat to your life or personal safety.
- You must leave the area immediately.
- Exiting the vehicle is unsafe.
- Unplugging the charge connector would unreasonably delay your departure or expose you to a risk to your personal safety.
After using the feature, Tesla requires the driver to schedule Service so the car can be inspected.

Tesla’s Cybercab battery design could make robotaxis even cheaper
Tesla built the Cybercab’s battery pack with spare room for a future switch to LFP.
Tesla built the Cybercab’s battery pack with empty space inside it on purpose, and the reason points to a cheaper robotaxi down the road.
Robert Sumpf, Tesla’s director of mechanical design engineering for battery modules and packs, said the extra room beside and beneath the Cybercab’s modules was left there so the company can move to lithium iron phosphate cells later. “So, we protected this pack to go to an even lower energy dense chemistry as we scale and need to bring LFP into the platform,” Sumpf said in a Cybercab deep dive with Munro Live.
The Cybercab runs on Tesla’s own 4680 cells with a nickel chemistry today. LFP cells store less energy for their size, so a straight swap would cut range. The reserved space lets Tesla add more LFP cells to make up the difference. In return, Tesla would get cells that cost less, run cooler and survive more charge cycles. LFP became the most used EV battery chemistry in the world last year.
Not all of that room was planned for a chemistry change. Lars Moravy, Tesla’s Vice President of Vehicle Engineering, said part of it exists because “we didn’t need as many batteries as we thought we did.” Tesla told Sandy Munro in early 2025 that it was targeting a Cybercab pack under 50 kWh with close to 300 miles of range.
The pack also breaks from the structural design Tesla used in some Model Y and Cybertruck builds. Instead of potting hundreds of cells into one block, the Cybercab uses four separate, individually sealed modules, so a bad module can be replaced without scrapping the whole pack. Sumpf was blunt about the older approach, giving the Model Y structural battery “a grade D” because it was hard to build and nearly impossible to repair. He estimated a fully structural pack gains about 10% more cell volume, but said “the issue is the service cost.”
That cost matters more for a car that rarely sits parked. Cybercab chief engineer Eric Earley said replacing an entire pack “before half a million miles is a killer on cost,” which is why remanufacturing and serviceability were built into the design from the start.
The same Munro Live tour produced Moravy’s admission that the Cybercab line at Giga Texas is now outpacing Robotaxi deployments, along with a look at the robotaxi’s unorthodox paint process. Tesla is aiming to deliver the first Cybercabs to outside customers by the end of 2026, though Elon Musk has said the vast majority will stay owned by Tesla and run as a transport service.
Sumpf did not give a date for an LFP version, name a cell supplier or say how a chemistry change would affect range. For now, the 4680 cars keep piling up: Texas DMV records from Tuesday list 544 Cybercabs authorized for Tesla’s Robotaxi fleet, more than the 507 Model Ys on the same roster for the first time.
