Tesla had lowest tailpipe CO2 emissions & highest fuel economy in 2021 EPA Auto Trends report finds
Tesla had the lowest tailpipe CO2 emissions for 2021, a new report published by the U.S. Environmental Protection Agency (EPA) stated. The EPA released its annual Automotive Trends report, and findings reveal that Tesla is leading the way with the lowest tailpipe CO2 emissions and the highest fuel economy of all large manufacturers.
Naturally, Tesla is the leader since it doesn’t produce any vehicles with an internal combustion engine (ICE), and as a result, there are no tailpipes. However, other manufacturers such as Kia and Toyota are showing improvements now that they have begun producing electric vehicles.
Following Tesla, Subaru, Kida, Hyundai, Nissan, and Honda had reductions in CO2 tailpipe emissions. Stellantis had the highest new vehicle average CO2 emissions and lowest fuel economy of the large manufacturers, the report noted.
Tesla was followed by a close grouping of Subaru, Kia, Hyundai, Nissan, and Honda. Also, for the model year of 2021, Stellantis had the highest new vehicle average CO2 emissions and lowest fuel economy of the large manufacturers. General Motors and Ford followed Stellantis.
The table below shows manufacturers and vehicles with the highest fuel economy by year. The manufacturer with the highest fuel economy for both 2021 and 2022 (preliminary) was Tesla. Stellantis was the lowest and has been the lowest since 2012. The Tesla Model 3 was the overall vehicle with the highest fuel economy and is expected to be replaced by the Lucid Air in 2022.

The table below shows the estimated real-world fuel economy and CO2 emissions for vehicles from Model Year 2020-2022.

The report also noted that in 2021, hybrid vehicles reached a new high of 9% of all production.
“This increase was mostly due to the growth of hybrids in the truck SUV and pickup vehicle types. The combined category of electric vehicles (EVs), plug-in hybrid vehicles (PHEVs), and fuel cell vehicles (FCVs) increased to 4% of production in model year 2021 and are projected to reach 8% of production in model year 2022, due to expected growth in EV production across the industry,” it stated.
Other key findings from the report found that in 2021, the average estimated real-world CO2 emission rate for all new vehicles fell by 2 g/mi to 347 g/mi, which was the lowest ever measured.
“Real-world fuel economy remained at a record high 25.4 mpg.”
All vehicle types are at record-low CO2 emissions, and preliminary data shows that the emissions and fuel economy for 2022 are expected to improve from 2021 levels.

SpaceX reports its second earnings today: here’s what to expect
SpaceX (NASDAQ: SPCX) will report its second public earnings call today since its IPO earlier this year, and there are a few things we expect to hear about, as well as Wall Street analysts, who have already outlined their expectations for the call.
Wall Street analysts have a consensus of $12.72 billion in revenue and an earnings per share (EPS) of $0.13. These are broken down into three sectors: Space, Connectivity, and AI/SI, which are perceived in this way:
- Space: $1.41 billion
- Connectivity: $4.84 billion
- AI/SI: $6.47 billion
Other outlets cluster near $12.8 or $12.9 billion in revenue and $0.14 – $0.15 EPS. This implies a roughly 65 percent sequential growth from Q2’s $7.81 billion, driven mostly by AI/SI, with the first post-IPO positive EPS expected.
Here are the three things to watch for on the call:
AI Revenue Ramp and the $100B+ ARR target
AI is truly the swing factor for SpaceX, and analysts expect it to roughly double from Q2’s $2.56 billion and become about half of total revenue. Management previously guided to a $100 billion+ annualized run rate by December, including the Cursor acquisition, which was $60 billion, to close the quarter.
Listen for updates on SpaceX’s compute capacity, especially pertaining to its contracts with Google, Anthropic, and others, revenue per watt, any new deals, and Cursor’s early contribution.
Starlink/Connectivity Metrics and Mobile Expansion
Connectivity remains a main profit engine for SpaceX. Subscriber additions will be something to pay attention to, as Q2 ended at 12 million and previews are looking at 14 million for this quarter. Additionally, ARPU trends, enterprise and government growth, and any commentary on Starlink Mobile will be something to pay attention to, especially following the recent low-band spectrum deal and FCC-related constellation approvals.
Capex Trajectory, Cash Burn/FCF, and Starship/Operational Updates
Q2 capex of roughly $18.4 billion weighed on the stock. Investors will look to scrutinize Q3 spending levels, any guidance on the pace into Q4/2027, free cash flow, backlog, and liquidity. Operational color on Starship (Flight 14 milestones and Flight 15 timing/reusability progress), Falcon cadence, and government/NASA contracts are also in focus.
Of course, there will also be some speculation on the potential Tesla-SpaceX merger, but there was nothing mentioned in the company’s proxy it sent earlier this week.
SpaceX will report earnings after market close today and will stream the call on X.

SpaceX just launched its secret Starfall saucer again
SpaceX launched its Starfall capsule again on Bandwagon-5, this time listed openly beside rideshare customers.
SpaceX launched its Starfall reentry capsule for the second time on Tuesday morning, flying it as the payload of the Bandwagon-5 rideshare mission. Falcon 9 lifted off from Space Launch Complex 40 in Florida at 7:04 a.m. ET with 32 payloads, and the first stage booster, on its 19th flight, landed on the droneship A Shortfall of Gravitas about nine minutes later.
Starfall was scheduled to separate last, 2 hours and 48 minutes after liftoff. The final customer satellite on SpaceX’s mission timeline comes off the upper stage about an hour and nine minutes in, which left a long gap before the capsule was due to be released alone. SpaceX later posted that the payload deployment sequence is complete. At liftoff, the company said Starfall “enables affordable, routine access to a microgravity environment, providing unique opportunities for on-orbit manufacturing, scientific research, and testing.”

As Teslarati reported before the first Starfall flight, SpaceX made no public announcement about the vehicle then, and nearly everything known came from FAA and FCC filings. This time Starfall is an item name on the official mission page, listed beside paying rideshare customers. SpaceX has still not said what, if anything, is aboard this Starfall, Spaceflight Now noted.
The FAA’s environmental assessment from May describes a disk about 10.2 feet wide and 2.5 feet tall that weighs roughly 4,600 pounds and can bring 2,200 pounds of payload back to Earth.
Interestingly, the same rocket also carries a competitor’s hardware. Varda Space Industries launched its W-Series 7 capsule on Bandwagon-5, a spacecraft about three times smaller than Starfall that will test whether microgravity can improve the solubility of a cancer drug called Protac. It is Varda’s ninth reentry capsule, and W-8 and W-9 launched earlier this month on Transporter-18. SpaceX has been Varda’s launch provider since the company’s first Falcon 9 rideshare contract in 2021.
SpaceX has not published where or how this Starfall will come down. The preview we ran in June described a recovery from the Pacific Ocean, and the company has not said whether this flight follows the same plan. The launch also arrives hours before SpaceX posts its third quarter results after the market closes, a report we previewed earlier this week.

The Boring Company’s latest Tesla tunnel truck mod “fits like a glove”
The Boring Company has modified a Tesla powered tunnel truck to carry freight containers underground.
The Boring Company has found a second job for the Tesla hardware it already runs underground. In a post on X, Elon Musk’s tunneling company showed its latest Prufrock Liner Truck modified to carry a standard 20 foot shipping container. “Using TBC tunnels to transport freight,” the company wrote. “The latest Prufrock Liner Truck (using Tesla Model 3 batteries and drive units) has been modified to carry a standard 20′ shipping container. Fits like a glove!”
The photo shows a red container sitting on a long, low white chassis parked outside, with drive hardware visible at one end. The Boring Company did not say where or when freight hauling would start, which customers it has in mind, or how many trucks it is converting.

Until now, the liner trucks have hauled concrete. Teslarati reported in August on Liner Truck 3, which uses Model 3 battery packs and drive units to move more than 22,000 pounds of precast tunnel segments to the boring machine. It has 28 miles of range, tops out at 12 mph, and is piloted remotely from the company’s operations center in Texas. The freight version appears to be the same platform with a different bed, and The Boring Company has not said whether it will also be remotely piloted.
Freight has been on the company’s menu for years. When TBC updated its product lineup in 2021, its freight tunnel was described as sized to fit a standard shipping container, “barely.” The company later used the idea at Tesla’s own factory, where Prufrock 3 dug a tunnel to Giga Texas that now moves finished Cybertrucks away from the production line.
The Boring Company closed a $3 billion Series D in September at a $23 billion valuation, and Teslarati has covered how that money is tied to a UAE tunneling push and a faster Nashville build. In Nashville, Prufrock MB1 and MB2 are mining at the same time, and a third machine is expected to launch in late October. Each machine needs a steady supply of liner trucks, so any design that works for segments and containers alike gives the company more use out of the same Tesla parts.
The Vegas Loop remains the only Boring Company system open to the public, and it moves passengers in Tesla vehicles. A freight service would be a separate product, and the post gave no indication that one is close to launch. For now, it is a truck, a container and a short caption saying they fit together.
