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.

Tesla FSD’s newest model is coming, and it sounds like ‘the last big piece of the puzzle’
“There’s a model that’s an order of magnitude larger that will be deployed in January or February 2026.”
Tesla Full Self-Driving’s newest model is coming very soon, and from what it sounds like, it could be “the last big piece of the puzzle,” as CEO Elon Musk said in late November.
During the xAI Hackathon on Tuesday, Musk was available for a Q&A session, where he revealed some details about Robotaxi and Tesla’s plans for removing Robotaxi Safety Monitors, and some information on a future FSD model.
While he said Full Self-Driving’s unsupervised capability is “pretty much solved,” and confirmed it will remove Safety Monitors in the next three weeks, questions about the company’s ability to give this FSD version to current owners came to mind.
Musk said a new FSD model is coming in about a month or two that will be an order-of-magnitude larger and will include more reasoning and reinforcement learning.
He said:
“There’s a model that’s an order of magnitude larger that will be deployed in January or February 2026. We’re gonna add a lot of reasoning and RL (reinforcement learning). To get to serious scale, Tesla will probably need to build a giant chip fab. To have a few hundred gigawatts of AI chips per year, I don’t see that capability coming online fast enough, so we will probably have to build a fab.”
NEWS: Elon Musk says FSD Unsupervised is “pretty much solved at this point” and that @Tesla will be launching Robotaxis with no safety monitors in about 3 weeks in Austin, Texas. He also teased a new FSD model is coming in about 1-2 months.

It rings back to late November when Musk said that v14.3 “is where the last big piece of the puzzle finally lands.”
With the advancements made through Full Self-Driving v14 and v14.2, there seems to be a greater confidence in solving self-driving completely. Musk has also personally said that driver monitoring has been more relaxed, and looking at your phone won’t prompt as many alerts in the latest v14.2.1.
This is another indication that Tesla is getting closer to allowing people to take their eyes off the road completely.
Along with the Robotaxi program’s success, there is evidence that Tesla could be close to solving FSD. However, it is not perfect. We’ve had our own complaints with FSD, and although we feel it is the best ADAS on the market, it is not, in its current form, able to perform everything needed on roads.
But it is close.
That’s why there is some legitimate belief that Tesla could be releasing a version capable of no supervision in the coming months.
All we can say is, we’ll see.

SpaceX IPO is coming, CEO Elon Musk confirms
However, it appears Musk is ready for SpaceX to go public, as Ars Technica Senior Space Editor Eric Berger wrote an op-ed that indicated he thought SpaceX would go public soon. Musk replied, basically confirming it.
Elon Musk confirmed through a post on X that a SpaceX initial public offering (IPO) is on the way after hinting at it several times earlier this year.
It also comes one day after Bloomberg reported that SpaceX was aiming for a valuation of $1.5 trillion, adding that it wanted to raise $30 billion.
Musk has been transparent for most of the year that he wanted to try to figure out a way to get Tesla shareholders to invest in SpaceX, giving them access to the stock.
He has also recognized the issues of having a public stock, like litigation exposure, quarterly reporting pressures, and other inconveniences.

Musk replied, basically confirming it:
As usual, Eric is accurate

Berger believes the IPO would help support the need for $30 billion or more in capital needed to fund AI integration projects, such as space-based data centers and lunar satellite factories. Musk confirmed recently that SpaceX “will be doing” data centers in orbit.
AI appears to be a “key part” of SpaceX getting to Musk, Berger also wrote. When writing about whether or not Optimus is a viable project and product for the company, he says that none of that matters. Musk thinks it is, and that’s all that matters.
It seems like Musk has certainly mulled something this big for a very long time, and the idea of taking SpaceX public is not just likely; it is necessary for the company to get to Mars.
The details of when SpaceX will finally hit that public status are not known. Many of the reports that came out over the past few days indicate it would happen in 2026, so sooner rather than later.
But there are a lot of things on Musk’s plate early next year, especially with Cybercab production, the potential launch of Unsupervised Full Self-Driving, and the Roadster unveiling, all planned for Q1.

Tesla adds 15th automaker to Supercharger access in 2025
Tesla has added the 15th automaker to the growing list of companies whose EVs can utilize the Supercharger Network this year, as BMW is the latest company to gain access to the largest charging infrastructure in the world.
BMW became the 15th company in 2025 to gain Tesla Supercharger access, after the company confirmed to its EV owners that they could use any of the more than 25,000 Supercharging stalls in North America.
Welcome @BMW owners.

Newer BMW all-electric cars, like the i4, i5, i7, and iX, are able to utilize Tesla’s V3 and V4 Superchargers. These are the exact model years, via the BMW Blog:
- i4: 2022-2026 model years
- i5: 2024-2025 model years
- 2026 i5 (eDrive40 and xDrive40) after software update in Spring 2026
- i7: 2023-2026 model years
- iX: 2022-2025 model years
- 2026 iX (all versions) after software update in Spring 2026
With the expansion of the companies that gained access in 2025 to the Tesla Supercharger Network, a vast majority of non-Tesla EVs are able to use the charging stalls to gain range in their cars.
So far in 2025, Tesla has enabled Supercharger access to:
- Audi
- BMW
- Genesis
- Honda
- Hyundai
- Jaguar Land Rover
- Kia
- Lucid
- Mercedes-Benz
- Nissan
- Polestar
- Subaru
- Toyota
- Volkswagen
- Volvo
Drivers with BMW EVs who wish to charge at Tesla Superchargers must use an NACS-to-CCS1 adapter. In Q2 2026, BMW plans to release its official adapter, but there are third-party options available in the meantime.
They will also have to use the Tesla App to enable Supercharging access to determine rates and availability. It is a relatively seamless process.
