Tesla Cybertruck isn’t better than 1949 technology when it comes to off-roading, says popular Trucking channel
The Tesla Cybertruck is, without a doubt, one of the most discussed vehicles in recent memory. The pickup’s polarizing and robust design has vehicle fanatics raving about the possibility of changing the tune of the American truck market today. In a recently published video from The Fast Lane Car YouTube channel, the team discussed why they believe the Cybertruck will fail to be an effective mode of off-road transportation. They highlight its heavy-weight and low-body design as two of the reasons it will fall short of impressively navigating through rocks and trails.
“If you look at what you need for off-road ability, you need ground clearance, you need gearing, you need articulation, you need underbody protection, right?” The trucking experts add, “If you look at the off-road tech, the stuff that you needed back in 1949 is the stuff you still need in 2020-2021.”
Typically, offroading vehicles that find success in challenging terrain have short wheelbase are lightweight and tend to told hold higher-than-normal ground clearances that assist in traveling over sharp crests on trails. TFL’s Tommy Mica highlights these attributes during the video, stating that an offroading vehicle’s biggest enemy is weight.
“Just like on-road, the enemy to off-road is weight. The lighter the weight, the easier it is to crawl up obstacles to maneuver difficult situations. The Cybertruck is going to be huge and is going to be monstrously heavy,” Mica says.
While it is ideal to have a lighter vehicle for offroading situations, that does not mean a heavy car will have issues 100% of the time. In fact, there are many vehicles that hold a weight that is similar to the Cybertruck’s estimated 5,000-6,500 pound curb rating. One is the 2019 Ford F-150 Raptor, a truck that was recognized by Popular Mechanics as one of the top 12 best off-road vehicles available. Weighing in at over 5,500 pounds, the Raptor has been spotted climbing intimidating stretches of steep offroading trails without much of an issue.
Additionally, Mica states that the Cybertruck’s low ground clearance will inhibit the vehicle’s ability to navigate over steep land grades and sharp objects on a trail. However, the Cybertruck’s 16″ ground clearance is higher than the 8.7″ measurement of the top-ranked 2019 Ram 1500 Rebel from Dodge and the previously mentioned F-150 Raptor’s 11.5″ clearance.
TFL tested a Long-Range configuration of the Model X in its off-road tests. Citing a diminished loss of range due to increased power usage, and increased worry over puncturing the vehicles underbody battery pack made their experience not-so-memorable. However, the Model X was never aimed toward off-road performance specifically. While the electric SUV does have traction control capabilities that have performed well on off-road courses in the past, the Model X was not meant for navigating through vicious trails of rocks, branches, and uneven terrain.
Even so, using the Model X’s performance as an off-road vehicle as the basis to prove the Cybertruck’s inability to function on trails just seems silly. The two cars maintain entirely different packages. Comparing a Ford Escape’s off-road performance to the F-150 Raptor’s wouldn’t be justifiable either, as the two vehicles are completely different and aimed toward different functions.
Besides, Tesla CEO Elon Musk has stated that the Cybertruck’s size and dimensions are not finalized. In early December 2019, Musk said the width and length would both be revised to fit inside a residential garage. “We can prob reduce width by an inch & maybe reduce length by 6+ inches without losing on utility or aesthetics,” Musk said.
The Cybertruck’s off-road performance won’t be solidified until the release of its Dual and Tri motor variants in 2021. However, there is plenty of evidence to suggest that the electric truck will be more than capable of holding its own in tight terrain, especially considering its most powerful variant packs a tremendous punch.

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.
