US Environmental Protection Agency (EPA) test documents have revealed a number of interesting tidbits about the 2022 Rivian R1T and R1S, including the vehicles’ peak DC charging rate and their absence of a heat pump.
The documents, which could be viewed here, were initially shared in the Rivian Forums and the Rivian Owner’s Forum. As could be seen in the documents, the 2022 Rivian R1T and R1S have a peak DC charging rate of 210 KW, which is right in line with what the company quoted for its proprietary DC Adventure Network. Similar to Tesla Superchargers, the Adventure Network is designed specifically by Rivian for its vehicles, though the company has noted that the system could be opened to other EVs in the future.

Rivian has been quite subtle about the Adventure Network’s full specs, though the company has noted that its fast chargers would offer over 200 kW output for the R1T and the R1S. This should allow the all-electric pickup truck and SUV to replenish up to 140 miles of range in 20 minutes. Rivian did state that further improvements down the line would likely improve the fast chargers to over 300 kW.
Interestingly enough, Rivian’s EPA test documents also featured a specific section for the R1T and R1S’ heat pump, though a look at the filings itself reveals that the vehicles are not equipped with the component. Considering that heat pumps are known to increase the efficiency of electric vehicles in the cold, it would be quite interesting to see how the R1T and the R1S’ range could hold up in places with extremely cold temperatures.

It should be noted, however, that the specs listed in the EPA test documents are specifically for the 2022 Rivian R1T and R1S for now. Considering that the company has spoken about upgrading its rapid chargers in the past, and the fact that the design of the vehicles is being improved on a rapid basis, there is a good chance that succeeding iterations of the flagship all-electric pickup truck and SUV may feature improvements such as peak charging rates that could stand toe to toe with some of the best in the industry today.

Elon Musk shares updated Starship V3 maiden launch target date
The comment was posted on Musk’s official account on social media platform X.
SpaceX CEO Elon Musk shared a brief Starship V3 update in a post on social media platform X, stating the next launch attempt of the spacecraft could take place in about four weeks.
The comment was posted on Musk’s official account on social media platform X.
Musk’s update suggests that Starship Flight 12 could target a launch around early April, though the schedule will depend on several remaining milestones at SpaceX’s Starbase launch facility in Texas.
Among the key steps is testing and certification of the site’s new launch tower, launch mount, and tank farm systems. These upgrades will support the next generation of Starship vehicles.
Booster 19 is expected to roll to the launch site and be placed on the launch mount before returning to the production facility to receive its 33 Raptor engines. The booster would then return for a static fire test, which could mark the first time a Super Heavy booster equipped with Raptor V3 engines is fired on the pad.
Ship 39 is expected to undergo a similar preparation process. The vehicle will likely return to the production site to receive its six engines before heading to Massey’s test site for static fire testing.
Once both stages are prepared, the booster and ship will roll out to the launch site for the first full stack of a V3 Super Heavy and V3 Starship. A full wet dress rehearsal is expected to follow before any launch attempt.
Elon Musk has previously shared how SpaceX plans to eventually recover Starship’s upper stage using the launch tower’s robotic arms. Musk noted that the company will only attempt to catch the Starship spacecraft after two successful soft landings in the ocean. The approach is intended to reduce risk before attempting a recovery over land.
“Should note that SpaceX will only try to catch the ship with the tower after two perfect soft landings in the ocean. The risk of the ship breaking up over land needs to be very low,” Musk wrote in a post on X.
Such a milestone would represent a major step toward the full reuse of the Starship system, which remains a central goal for SpaceX’s long-term launch strategy.

Tesla opens first public Tesla Semi Megacharger site in Los Angeles
The development was highlighted in a post on social media platform X by the official Tesla Semi account.
Tesla has opened its first public Tesla Semi Megacharger site in Los Angeles. The station reportedly offers up to 750 kW charging speeds and is open to Tesla Semi customers.
The development was highlighted in a post on social media platform X by the official Tesla Semi account.
Tesla Semi Megachargers
The Los Angeles site seems to be the first public Tesla Semi Megacharger that is not located at a Tesla factory. It is also the third Megacharger site currently visible on Tesla’s map.
The Megacharger system is designed specifically for the Tesla Semi and is capable of delivering extremely high charging speeds to support long-haul trucking operations. Infrastructure such as this will likely play a key role in making the Semi competitive with diesel-powered transport trucks.
Tesla’s progress with the Semi has also drawn attention in recent days after Elon Musk biographer Ashlee Vance shared photos from inside the Tesla Semi factory near Giga Nevada. The images suggested that preparations for higher production volumes may be underway, hinting that a broader ramp of the Tesla Semi’s production indeed be approaching.
New deployment strategies
Tesla has continued expanding its broader charging network through several new strategies aimed at accelerating infrastructure deployment. One of these initiatives is the Supercharger for Business program, which allows third parties to purchase Tesla Supercharger equipment and deploy charging stations while still integrating with Tesla’s network.
The program recently marked a milestone in Alpharetta, Georgia, where the city deployed four 325 kW city-branded Superchargers near the Alpharetta Department of Public Safety on Old Milton Parkway. The chargers support the city’s Tesla Model Y police vehicles while also remaining accessible to the public.
As per a report from EVwire, the project was designed not only to support fleet charging but also to generate economic returns that could offset the city’s investment. Tesla’s Supercharger for Business program has already attracted several participants, including businesses and charging providers such as Suncoast Charging, Pie Safe bakery in Idaho, Francis Energy in Oklahoma, and Wawa convenience stores.

The Boring Company’s Vegas Loop moves 82k riders during CONEXPO
The Loop’s feat was highlighted by The Boring Company in a post on its official account on social media platform X.
The Boring Company said its Vegas Loop system transported roughly 82,000 passengers during the recent CONEXPO-CON/AGG construction trade show in Las Vegas. The event was held at the Las Vegas Convention Center (LVCC) from March 3-7, 2026.
The Loop’s feat was highlighted by The Boring Company in a post on its official account on social media platform X.
CONEXPO-CON/AGG 2026
CONEXPO-CON/AGG is one of the largest construction trade shows in North America. This year’s event was quite impressive, attracting more than 140,000 construction professionals from 128 countries across the world.
Considering the number of this year’s attendees, the LVCC Loop seemed to have proven itself to be a very useful transportation solution. A video posted by The Boring Company on its official X account featured attendees expressing their enthusiasm for the underground transport system, with some stating that they would like to see similar tunnels across Las Vegas.
The LVCC Loop is only part of the greater Vegas Loop network, which is actively under construction.
New Vegas Loop extensions
One of the newest additions is a station at the Fontainebleau Las Vegas resort on the Strip. The station is located on level V-1 of the resort’s south valet area, according to a report from the Las Vegas Review-Journal. From the Fontainebleau, passengers can travel free of charge to stations serving the Las Vegas Convention Center, as well as to Loop stations at Encore and Westgate.
The system is also expanding beyond the Strip corridor. In December, The Boring Company began offering Vegas Loop rides to and from Harry Reid International Airport. These trips include a limited above-ground segment after receiving approval from the Nevada Transportation Authority to allow surface street travel tied to Loop operations.
The Boring Company President Steve Davis previously told the Review-Journal that the University Center Loop segment, which is currently under construction, is expected to open in the first quarter of 2026. The extension would allow Loop vehicles to travel beneath Paradise Road between the convention center and the airport, with a planned station just north of Tropicana Avenue.
