Adoption of Tesla’s electric truck will be driven by regulation
It’s expected that the commercial trucking industry will begin to transform in the same way that the passenger automotive industry has. Fuel efficiency has become a new priority and electrification is now the go-to plan for achieving higher MPGs in heavy trucking. In much the same way that regulations pushed trucking towards lower pollution at the expense of efficiency in the 1970s, today’s trucking paradigm is seeing a push for more efficiency. At what expense?
A new report from Ravi Shanker at Morgan Stanley urges investors to consider electric and self-driving commercial trucking as an opportunity. Shanker says that regulations and economics will drive the industry towards electrification and autonomous technologies. The analyst says that this could happen as early as 2020, which is when new federal fuel economy regulations on heavy-duty vehicles begin to really gather steam. Although efficiency gains will be had with electrification and self-driving, Shanker makes it clear that this will be secondary to the demand created by regulatory pressure.
As usual, we look to California for a glimpse of what could be coming. California’s Sustainable Freight Action Plan calls for 100,000+ zero-emissions trucks to be on the road by 2030 in that state. There is debate as to whether this plan is realistic, but federal standards are also playing a large role. The U.S. Environmental Protection Agency (EPA) and the National Highway Traffic Safety Administration (part of the federal Department of Transportation) have proposed emissions and fuel economy standards for heavy-duty vehicles. The first of these began with the 2014 model year.
For our purposes, the regulations affecting “combination tractors” (aka “tractor-trailer” or “18 wheeler”) models are pertinent. The 2018 standards are relatively loose and most in the industry believe they are achievable, but the EPA and NHTSA have proposed further standards to begin in 2021, with incremental increases thereafter through to 2027. The goals are largely aimed towards lower CO2 emissions with reductions of about four percent (depending on the vehicle type) being the goal. The reduction is not the issue with industry insiders, however, it’s the test cycle to be used, which some argue is less realistic and which disfavors other emissions that also have requirements to be met. This Phase 2 of the federal efficiency standards for heavy trucks is not yet finalized, but will very likely be the driving force behind national changes in trucks.
Equating these changes into standard numbers that the general public would understand is difficult. Heavy-duty trucks can range in fuel efficiency from 20 mpg or better down to 2-3 mpg. For most tractor-trailer combinations, MPG averages of 4-9 mpg are the norm, depending on load, tractor type, and area of operation. Most analysts calculate efficiency using fuel use in tons per mile with a relatively long distance (100-500 miles) being the average. Using this method, for example, in my time driving a tractor pulling a refrigerated trailer across all 48 states, my fuel economy average was about average for that sector of the industry at roughly 60 ton-miles per gallon. Today, these numbers are slightly higher, according to the latest U.S. Transportation Energy book. Using this method of calculation, a 2015 Toyota Prius is about a third as efficient at moving freight as was my truck.
This doesn’t mean there isn’t room for improvement, of course. There are more companies than Tesla working towards deleting the smoke stacks from big trucks.
In Europe, Volvo trucks is working hard towards a zero-emissions (at the tailpipe anyway) trucking solution with several approaches being tested. An overhead tram-like charging system has been deployed for a short stretch of highway in Sweden, aiming to improve plug-in trucks’ range in EV mode. Short-haul battery electrics and two different versions of autonomous (or semi-autonomous) systems are also being tested.
Here in the States, Volvo’s Mack Trucks is working on a handful of electrification options for heavy-duty drivetrains. So is Daimler (Freightliner, Western Star in the U.S.). Startups like Nikola also have eyes on this electric trucking future. Other startups have hoped to get into the mix as well, but the failure rate is high with companies like Smith Electric, Vision Industries, and Boulder Electric having designed and marketed innovative commercial truck options that ultimately never caught on.
Meanwhile, the largest maker of electric heavy vehicles is Chinese maker BYD, who branched out from making gadget batteries into building electric buses, trucks, and more. They are currently filling contracts internationally for buses and trucks in places as disparate at California, Malaysia, and Europe. BYD builds battery-electric, hydrogen fuel cell electric, plug-in hybrid, and hybrid drivetrains and machines for several commercial market sectors.
So we can guarantee that changes to the trucking industry are coming, but no one can say how fast or how much change that will be. Current federal regulations will drive the industry forward until 2018 and it’s likely that new standards will be in place to keep carrying change forward after that. California’s ambitious plans for adopting electric trucks will be largely regulation and incentive driven, but that has down sides as well. Many of the startups we’ve seen who’ve created electrified big rigs or delivery trucks ultimately failed when the incentives began to dry up.
For Tesla, this could mean that the financial case for the Tesla Semi will need to be more economics-based and less dependent on single market, incentives-based plans. This means that Elon and Co should be looking beyond California and it’s 100,000 vehicle plans into a broader market. We’ll discuss the potential economic case for a Tesla Semi in a future editorial.
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.
