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. You can listen to the full interview with Ian Wright in Episode 2 on September 13th on the NextMobility podcast.
The first episode premieres next Wednesday.

Elon Musk handed Grok something no other AI company can get their hands on
Elon Musk says SpaceX will feed engineering data into Grok’s next model, avoiding restricted material.
Elon Musk said Tuesday that SpaceX will feed its internal engineering data into the next major training run for Grok, the AI model now folded into SpaceX following February’s merger. In a post on X, Musk wrote that SpaceX’s “massive corpus of world-class engineering data,” excluding anything restricted under U.S. arms export law, will be added during supplemental training of what he called the “2T run,” a reference to a roughly two trillion parameter model that would nearly double the parameters behind the latest Grok 4.5 that’s rolling out.
SpaceX’s massive corpus of world-class engineering data (excluding material blocked by ITAR) will be added during supplemental training of the 2T run.
This will dramatically improve Grok’s engineering capabilities. https://t.co/BbQEViFByn

The excluded material that Musk is referring to would fall under the International Traffic in Arms Regulations (ITAR), which restricts export of technical data tied to defense and space hardware. That likely rules out propulsion specifics for Merlin and Raptor engines along with guidance and control details for SpaceX’s launch vehicles, but leaves manufacturing knowledge, materials science, and Starlink hardware design on the table.
The announcement extends a pattern that has been building since SpaceX’s Nasdaq debut in June, when the company went public with Grok and xAI’s Colossus supercomputer folded into the pitch to investors.
Days after that listing, SpaceX closed its $60 billion all stock acquisition of coding startup Cursor, giving xAI both enterprise software distribution and a stream of real world developer data to train on. Grok 4.5 launched July 8 running partly on that Cursor training data, with Musk describing it as roughly comparable to Anthropic’s Opus 4.7 but faster and cheaper to run.
Feeding SpaceX’s own engineering data into the next AI model follows the same logic Musk has applied across xAI’s sister companies. Tesla supplies real world driving data and manufacturing expertise, X supplies conversational data, and now SpaceX supplies aerospace engineering data built up since 2002.
Musk did not give a release date for the upcoming AI model, referred to elsewhere as Grok 4.6. He has said the two trillion parameter run is in its final training phase and expected to wrap this week.
Tesla has extended its Bay Area ride-hailing service to include pickups and drop-offs at San Francisco International Airport (SFO). The update, shared via the company’s official channels on July 21, allows users in the region to request rides directly to and from one of California’s busiest airports.
The expansion builds on Tesla’s secured limousine permit for SFO operations. Public records show the permit became effective March 20, 2026, and remains active through January 31, 2027. Tesla vehicles operating the service now display authorized limousine permits issued by the City and County of San Francisco.

Tesla’s ride-hailing program in California relies on Model Y vehicles equipped with Full Self-Driving (Supervised) technology. Human safety drivers remain present in compliance with state regulations, distinguishing the service from fully driverless operations.
The Bay Area geofence covers a broad area spanning north of San Francisco to south of San Jose, offering extensive connectivity across the region.
UPDATE: Elon Musk reveals why Tesla didn’t say ‘Robotaxi’ upon California launch
This SFO addition follows earlier progress at other Bay Area airports. Tesla previously expanded service to San Jose Mineta International Airport (SJC) in late 2025. The company had engaged with SFO, SJC, and Oakland International Airport officials as early as September 2025 to secure necessary approvals for passenger transport.
The service provides a new option for travelers seeking electric, app-based transportation integrated with Tesla’s ecosystem. Rides are booked through Tesla’s dedicated ride-hailing application, which handles matching, routing, and payments. Pricing follows standard ride-hailing models, with potential adjustments based on distance, time, and demand.
Tesla’s California ride-hailing program launched in July 2025 with an initial invite-only rollout in the Bay Area. It started alongside operations in Austin, Texas, marking the company’s second major U.S. market.
The Bay Area remains a primary focus in California, with service centered on high-demand corridors connecting residential, commercial, and now major transportation hubs. This latest airport integration represents a practical step in Tesla’s broader mobility ambitions within the state.
