Tesla Semi gets ‘peppy and quiet’ hydrogen fuel cell competitor from Kenworth-Toyota
With support from the California Air Resources Board, Japanese auto giant Toyota and truck maker are collaborating to develop and build a limited run of hydrogen fuel trucks. The vehicles, which are Kenworth T680 trucks modified with Toyota’s hydrogen fuel cell powertrains, are expected to drive on routes around Los Angeles and further inland to San Bernardino. The actual specs of the vehicles have not been announced by either company, but the range of the hydrogen fuel cell T680 trucks are said to be 300 miles in “normal drayage operating conditions.”
Toyota and Paccar, the parent company behind Kenworth, took the wraps off the first hydrogen fuel cell long-hauler at this month’s Consumer Electronics Show in Las Vegas. The vehicle, which is classified as a Class 8 truck, stands to be a possible competitor for upcoming all-electric trucks like the Tesla Semi in the future. In a statement to CNBC, Brian Lindgren, Kenworth’s director of research and development, noted that utilizing hydrogen as a source of propulsion makes more sense for Class 8 vehicles than batteries, which power vehicles like Tesla’s all-electric long-hauler.
“We believe that carrying energy in the form of hydrogen for heavy-duty Class 8 trucks makes more sense than carrying it in batteries because the trucks can be refilled faster and offer longer range,” he said.
Lindgren’s point about faster refilling times for hydrogen fuel cell vehicles is quite justified, considering that a passenger car such as a Toyota Mirai could refill its tank with around 300 miles of range in roughly five minutes. That’s significantly faster than Tesla’s Superchargers, which are capable of charging roughly 200 miles of range in 30 minutes. Larger vehicles such as the hydrogen-electric Kenworth T680 trucks would likely take longer to refill than a passenger car such as the Mirai, but there’s a good chance that the long-hauler could still refill its tank faster than the Tesla Semi could charge its batteries, even if it is plugged into the upcoming Megacharger Network.
Toyota-Paccar’s Kenworth T680 hybrid fuel cell trucks caught the attention of some CES attendees due to the vehicle’s silent operation, which is nearly comparable to an all-electric truck. Lindgren, for his part, noted that drivers who have operated the truck actually appreciated the silence of the vehicle. “Drivers like these trucks because they are peppy and quiet,” he said.
Andy Lund, the Toyota chief engineer on the project, further stated that the hydrogen-electric trucks would have the same payload capacity as a diesel rig. Unlike its fossil fuel-powered counterparts, the hydrogen fuel cell Kenworth T680 long-haulers would only require a four-speed transmission, which is far simpler than the 18-gear transmissions usually fitted on Class 8 diesel trucks.
If there is one thing that would probably go against Toyota and Paccar’s hydrogen trucks, though, it would be their fuel efficiency. Kenworth’s director of research and development noted that the prototype trucks currently consume hydrogen at roughly the same rate as present diesel trucks, at around 5-7 mpg. The only advantage of the vehicles, of course, is that the trucks would only produce water vapor from their exhausts. This is a substantial advantage, considering that the trucking industry accounts for about 23% of carbon emissions from transportation in 2016, according to the Environmental Protection Agency.
That said, this would be something that Tesla could capitalize on. During the electric long-hauler’s unveiling, Musk noted that the Semi would cost operators $1.26 per mile to run, less than the standard $1.51 per mile that diesel-powered vehicles cost. Musk’s estimate has been met by skepticism by veterans of the trucking industry, but if the Tesla Semi’s operating costs stay true to the CEO’s estimate, then the vehicle would most certainly give itself a notable advantage over diesel and hydrogen-powered rivals when it starts operating on America’s roads.
Hydrogen fuel cells remain a polarizing solution for sustainable transportation. Elon Musk, for one, has openly discussed his dislike for hydrogen-electric transportation. In a statement to Autocar in 2014, for one, Musk went so far as to describe hydrogen fuel cell systems as “mind-bogglingly stupid.”
“They’re mind-bogglingly stupid. You can’t even have a sensible debate. Consider the whole fuel cell system against a Model S. It’s far worse in volume and mass terms, and far, far, worse in cost. And I haven’t even talked about hydrogen being so hard to handle. Success is simply not possible. Manufacturers do it [FCEVs] because they’re under pressure to show they’re doing something ‘constructive’ about sustainability. They feel it’s better to be working on a solution a generation away rather than something just around the corner. Hydrogen is always labeled the fuel of the future – and always will be,” Musk said.
Elon Musk initially announced that the Tesla Semi would start production sometime in 2019. That said, later statements from Tesla’s head of investor relations Martin Viecha suggested that the electric car maker would “earnestly” start producing the Semi by 2020.
Tesla has officially launched the Model Y L in the United States and Puerto Rico for $61,990. It is the longer-wheelbase version of the Model Y, and has been available in China since last year.
Tesla brings the Model Y L to the U.S. just months after it phased out the only pure SUV in its lineup, the Model X. It is slightly longer than the Model Y configurations that are already available in the U.S., and features a three-row, six-seat setup with Captain’s Chairs being among the many features that make this a truly fantastic offering.
The Model Y L is priced competitively at $61,990, and features 325 miles of range and a 0-60 MPH in just 4.4 seconds.
Tesla also added a handful of new features that are not available in even the Premium Model Y. Here’s a full list of its features:
- Heated/Ventilated Front Seats with Powered Thigh Cushion
- Heated/Ventilated Captain’s Seats in Second Row with Powered Armrests & One-Touch Fold
- Heated Third-Row Seats with Power Recline, One-Touch Fold & Child Seat Anchors
- Improved Airflow, Increased Efficiency, More Range
- 89 cubic feet of trunk space
- Upgraded Acoustic Glass and Suspension to Minimize Road Noise
- Adaptive Damping for a Smooth, Stable Ride
- Staggered Tires for Enhanced Grip
- Larger Tailgate for Better Rear Visibility and Bigger Windows Overall
- 16″ First Row and 8″ Second Row Touchscreens
- 19-Speaker Immersive Tesla Audio
- 50W Wireless Charging Pads with Active Cooling and Charging Ports for All Other Seats
- FSD Supervised and Integrated Grok AI
Tesla is also delivering these first units as a “Launch Series,” which comes with additional features, such as:
- Door Trim Puddle Lights
- Suede Dashboard Wing
- Exterior and Interior Badging
- Floor Mats
- Sill Plates
The launch of the Model Y L in the U.S. marks a huge offering from Tesla to U.S. consumers. People have been calling for Tesla to bring a larger car to the U.S., and it needed it more than ever now that the Model X is gone.

It is a huge accomplishment for Tesla to get the Model Y L to the U.S., and after reporting strong deliveries today, it will be interesting to see how this car impacts future quarterly delivery reports.
Deliveries for the Model Y L “Launch Series” are slated for September or October of this year.
Tesla just told us twice that the Model Y L is coming to the U.S., and two social media posts definitely just tipped the company’s hand, as if they wanted it to be any other way.
The two social media posts basically confirm that the slightly longer version of the Model Y will be heading to the United States soon, and many have speculated that the company could launch the vehicle as soon as this weekend.
The first post was directly from Tesla, and it showed an incredibly long Dachshund, with words above that said, “Looking forward to the long weekend.”

Anyone who knows Tesla knows the company loves to troll its fans and have fun, and this is a perfect example of that. While not a direct acknowledgement, Tesla is very involved on social media, especially CEO Elon Musk’s platform X, and the company is well aware of what is being discussed within the community.
With recent sightings of Model Y L test mules in California, peeks of the vehicle at Giga Texas, and a large call for the car to come to the U.S., Tesla is simply stoking conversation with this.
However, the company also made another move that was recognized on social media. Tesla has a large gallery that includes photos of its products so media and others can use them. This gallery applies to the U.S. market specifically, unless otherwise specified.
Tesla uploaded a Model Y L to the Gallery last night:

This seems to be another indication that the Model Y L is coming to the United States.
Musk said last year that the Model Y L could make its way to the United States late this year, but it was not something that was set in stone by Tesla. The company definitely needs to establish something in the SUV market that is larger than the Model Y, and the Model Y L might be the answer.
Even still, there are consumers out there who would love Tesla to develop something even larger, like a competitor to the Tahoe or Expedition. Tesla has not really given much of an indication that it will go in that direction.
Tesla is using the vehicles’ internal microphones to improve build quality, Vice President of Engineering Lars Moravy revealed recently.
It’s no secret that Tesla is always finding ways to make its manufacturing operations more efficient, accurate, and valuable. Constantly trying to make its cars better, the company has never placed any restrictions on what it will do to improve everything from panel gaps to paint.
As Teslas have been driving autonomously on the property of the Gigafactory Texas plant for a while now, Moravy revealed to Herbert Ong in a new interview that cars rolling off production lines now autonomously navigate themselves through a bumps, squeaks, and rattles (BSR) portion of the line. This helps to identify any loose or improperly installed internal parts.
The cabin’s microphones, which are used for a variety of things in ownership, simultaneously monitor any noises inside the vehicle while it rolls through the BSR portion of the production line. Moravy actually revealed that Tesla is trying to build “Full Self-Hearing,” an AI system that will detect minor imperfections so they can be corrected before delivery.
It’s no secret that build quality is something that Tesla struggled with as it scaled to a fully massive production operation that manufactures over 1.6 million vehicles per year. However, in recent years, especially, there have not been as many complaints. Tesla has truly improved upon its build quality and paint quality over the past several years, especially in the U.S.
Tesla’s ‘megacasts’ are key to massive build quality improvements
While those improvements have been evident, there are still some complaints; no automaker is perfect with this. But this step will now ensure that every single car that rolls off the production lines at Gigafactory Texas will be void of any creaks, squeaks, or squeals when it leaves the factory.
This measure is one of the most unique we’ve seen in terms of a strategy to avoid build quality issues, but it is not exclusive to Tesla.
Ford uses acoustic analysis AI to find abnormalities in seat motors, climate control units, and other components. Suppliers and OEMs will also use microphone arrays or particle velocity sensors in end-of-line stations.
