Tesla Semi competition with 140 kWh battery emerges before reveal event, Tesla co-founder weighs in
This Article first appeared on:
Less than a month away from the Tesla Semi reveal event, competitors are emerging to challenge the Elon Musk-led company on its first foray into the commercial trucking sector. After witnessing Tesla’s wildly successful entrance into the passenger vehicle space, existing players in the trucking industry have already realized the potential disruption Tesla could bring in their own backyard.
Just yesterday, Cummins, a massive $27 billion truck manufacturer, announced they have built an electric truck that they plan to mass produce in the next two years. The electric truck carries a 140 kWh battery pack and fast-charging technology. The 140 kWh pack will allow the vehicle to travel up to 100 miles on a single charge and capable of recharging to full capacity in approximately one hour. Cummins also plans to include a range extender to raise the overall range to 300 miles. Similar to Tesla who recently announced that their all-electric truck will have between 200 to 300 miles of range, Cummins is mainly targeting short-haul trucking needs.
Tesla CEO Elon Musk first shared his plans in July 2016 when he announced the company’s plans to shake the trucking industry to its roots. And it was revealed earlier this month that Tesla has begun testing “platooning” technology to increase battery range. Platooning would allow the trucks to drive autonomously and close together to reduce aerodynamic drag.

But in order for platooning to work effectively, the trucks must be able to safely navigate the dense interstates in close proximity, with little to no risk towards other vehicles. Like most things, that is easier said than done. To understand the feasibility of platooning and electric heavy duty trucks, we spoke to one of the leaders in the industry, Wrightspeed.

If Wrightspeed sounds familiar, its probably because you’ve heard of its founder, Ian Wright. Ian was one of the co-founders of Tesla in 2003 and left the company in 2005 to pursue the commercial vehicle industry. Since then, Wrightspeed has designed and manufactured several different hybrid electric powertrains for buses, garbage trucks, and delivery vehicles.
Forget Platooning, Road-Trains are Coming
Here’s what Ian Wright had to say about Platooning and how he plans to tackle this issue.
“Why don’t you pull two of three trailers with one tractor, that would be a lot more efficient than platooning.” – Ian Wright, CEO and Founder of Wrightspeed.
While Wrightspeed isn’t ready to start producing a powertrain for a hybrid electric truck, they are looking at the market seriously. The company believes that in order to maximize savings for trucking operators, their still needs to be a range extender in trucks, at least until batteries are more dense.

A Tesla Semi was involved in a fatal collision on U.S. Highway 50 in Dayton, Nevada, on Sunday, June 28, 2026, marking the first known fatal crash involving the electric Class 8 truck. The incident occurred around 7:20 a.m. at the intersection with Traditions Parkway, approximately 40 miles east of Reno and close to Tesla’s Gigafactory Nevada.
According to the Lyon County Sheriff’s Office and the Nevada State Police Highway Patrol, a semi-truck struck two passenger vehicles stopped at a traffic signal. The truck hit the vehicles from behind. Two people were pronounced dead at the scene, and a third person suffered life-threatening injuries and was flown to a hospital, Forbes reported.
Preliminary statements gathered at the scene by the Lyon County Sheriff’s Office suggested the truck driver may have fallen asleep at the wheel. However, the Nevada Highway Patrol, which is leading the investigation, stated that the official cause has not yet been determined.
Additional information is expected to be released early the following week. The truck was seized for evidence as part of the ongoing probe.
Responders at the scene included deputies from the Lyon County Sheriff’s Office, personnel from the Nevada Highway Patrol, Central Lyon County Fire Department, and the Nevada Department of Transportation. The crash led to the temporary closure of U.S. 50 in both directions.
The Tesla Semi is Tesla’s battery-electric heavy-duty truck, produced at the nearby Gigafactory in Nevada. Authorities initially described the vehicle as a semi-truck; its make was subsequently confirmed through reporting and scene identification; an interesting bit of information here, as the Semi is not yet available publicly and many do not know that Tesla builds electric trucks.
The investigation remains active, with no further official details on contributing factors or vehicle systems released as of early July 2026.
This incident highlights ongoing scrutiny of commercial vehicle safety on Nevada highways, particularly involving fatigue. Law enforcement continues to gather evidence and witness statements.
Tesla has expanded its Robotaxi program to Miami, Florida, marking the third state the autonomous ride-hailing platform has made its way to since launching last Summer.
Tesla announced today that the Robotaxi suite would now officially launch rides in a geofence in Miami:

The first geofence in Miami covers approximately 10 to 14 square miles. The area appears to be focused on western and central Miami, including Miami International Airport (MIA). It also includes popular routes like SR 826 (Palmetto Expressway), US 41 (Tamiami Trail), and connectors such as SR 968, 953, 959, and 972.
This is Tesla’s initial Miami launch zone, smaller and more targeted than some competitors’ areas (for example, Waymo’s initial rollout was broader in eastern neighborhoods). It prioritizes high-traffic, airport-linked routes before wider expansion.
The expansion is a huge signal for Tesla that it is now operating in Florida, a heavy-traffic state with many tourist areas, including Fort Lauderdale, Palm Beach, and the Boynton area, all of which are coastal and will attract perhaps millions of tourists in any given year.

The Tesla Robotaxi network launched last year on June 22, in Austin, Texas, beginning limited commercial operations in that city. It expanded shortly thereafter into the San Francisco Bay Area of California in late July 2025, marking entry into a second state with service covering key areas such as San Francisco, San Jose, and Berkeley.
Full commercial service was achieved in Austin by November 18, 2025, strengthening its presence within Texas before further growth.
In 2026, the network continued expanding across Texas with the addition of Dallas and Houston on April 18, significantly broadening its footprint in the state. This new launch into Miami marks Tesla entering a new state and bringing active locations to include Austin, Dallas, Houston, San Antonio in Texas, and the Bay Area in California.
These sequential expansions have steadily increased the network’s reach across major metropolitan areas in Texas, California, and Florida, focusing on scaling operations city by city and state by state since the initial Austin debut.
Tesla CEO Elon Musk has tempered expectations for the company’s humanoid robot Optimus, emphasizing that initial production will ramp up slowly despite recent progress on the manufacturing line. In a July 1 reply on X, Musk responded to optimistic community speculation by stating, “No, Optimus production will be extremely slow at first, as everything is new. This is not like making a car.”

The comment came in response to a post theorizing that Tesla had accelerated Optimus V3 development and might soon unveil an impressive demonstration with multiple units already in meaningful production. Musk’s clarification highlights the fundamental differences between scaling a novel humanoid robot and Tesla’s established automotive operations, which benefit from over a century of refined supply chains, tooling, and processes.
Recent updates show tangible advancement. Musk shared a photo of himself walking the Optimus production line at Fremont, where Tesla is converting former Model S/X manufacturing space. According to Q1 2026 earnings commentary, limited production is slated to begin in late July or August 2026 on this converted line.
Tesla Optimus project fires up as Musk sees production line progress
Musk previously noted that Optimus features roughly 10,000 unique parts, making early output rates “literally impossible to predict” and describing them as “quite slow.” A larger dedicated factory at Giga Texas is under construction, targeting higher-volume production around summer 2027 with long-term annual capacity potentially reaching millions of units.
Some experts point out that pioneering humanoid robotics demands inventing new automation techniques, actuator supply chains, and quality-control standards in real time. Unlike vehicles, where components and assembly methods are mature, every element of Optimus—from dexterous hands to AI-integrated movement—requires fresh engineering solutions. Early units are expected to handle simple factory tasks before expanding to more complex roles.
This cautious approach aligns with Tesla’s history of under-promising and over-delivering on complex technologies. While enthusiasts hoped for rapid deployment, Musk’s message underscores a deliberate strategy: prioritize reliability and iterative improvement over rushed volume.
Analysts suggest the S-curve ramp typical of new manufacturing will eventually accelerate once foundational issues are resolved, positioning Optimus as a potential trillion-dollar product line.
Musk has long envisioned Optimus transforming labor markets, assisting in homes, factories, and hazardous environments. By setting realistic timelines, Tesla aims to build sustainable momentum rather than risk disappointment. As the Fremont line comes online this summer, investors and fans will watch closely for the first production metrics and capability demonstrations.
