This is a preview from our weekly newsletter. Each week I go ‘Beyond the News’ and handcraft a special edition that includes my thoughts on the biggest stories, why it matters, and how it could impact the future.
Tesla has tapped a new type of automotive glass from supplier AGP for the Plaid Model S, invoking the thought that everything, even the finest details of the vehicle, was considered a possible improvement for the company’s rebirth of the all-electric, flagship sedan.
Many months ago, Teslarati stumbled across a list of Tesla’s suppliers through international connections. These suppliers were shipping massive volumes of whatever product they were giving to Tesla on cargo ships, and we noticed that there was a company called AGP that was shipping windshields and other automotive glasses to the company’s Fremont Factory.
It turns out that AGP has been providing Tesla with automotive glass for several years. Back in 2016, AGP provided glass for the Model X’s panoramic roof and windshields. However, Tesla utilized AGC Automotive’s windshields for its cars, according to Investopedia.
AGP is a Peru-based company that specializes in all types of automotive glass, but what they’ve done for Tesla is especially interesting. The company has been in business for 50 years, but just like everything else, it changes, and the automotive industry is no different. As electric vehicles have become more mainstream, technologies surrounding the development of these new, sustainable automobiles are popping up left and right. AGP’s eGlass for electric and autonomous vehicles is no different.
Now, AGP says on its website that it collaborates “closely with the companies that are leading the new wave of the electric and autonomous vehicles of tomorrow.” When I first stumbled across AGP many months ago on the cargo ship list for Tesla, there was no indication that there was an official partnership, so I looked into it a tad further. I reached out to AGP and received a response that thanked me for my inquiry but refused to confirm or deny whether it was in any sort of professional relationship with Tesla. Ironically, AGP gave the answer we needed, because responding to me was all I needed to know.
Many may ask, “What’s the significance of what glass Tesla is using on its cars?” There are plenty of automotive glass suppliers out there that are worth their weight in gold, providing high-quality windshields and windows for vehicles on the road. Of course, consumers are going to want something that is relatively high quality, because nothing is worse than driving behind a tractor-trailer on the Interstate, just to have a chip or small crack on your windshield from something as tiny as a pebble. While strength is undoubtedly a need for all windshields, EVs require a slightly different bit of development.
One of the biggest focuses for EVs is their drag coefficient. Why is it so important? Because aerodynamics are crucial to the performance, range, and effectiveness of electric vehicles. As high-quality, long-range batteries are hard to come by in the EV sector, manufacturers look for every advantage they can get to achieve robust range ratings. While Tesla is the leader in EV range figures, the company is still looking for ways to get all of its vehicles to or near the 400-mile threshold.
Aerodynamics are a great way to do that. And Tesla undoubtedly worked extremely hard to achieve the best-in-class drag coefficient of .208, beating out the Lucid Air’s impressive .21 coefficient.
We knew aerodynamics was going to be a big part of the Plaid Model S when it was spotted at the Nürburgring two years ago. The vehicle was sporting a large spoiler, a huge rear diffuser, and the new eGlass from AGP is just another addition to Tesla’s attempts to make the Plaid Model S the most aerodynamic vehicle in its lineup.

We finally confirmed that AGP was providing the highly aerodynamic and EV-specific automotive glass to the Model S Plaid thanks to Tesla Raj, who took a picture of the manufacturer’s sticker on the window of the all-electric sedan at Tesla’s Delivery Event on June 10th. This all confirmed Teslarati’s discovery of AGP in its supplier list several months ago and also confirmed that the two companies had a partnership, despite AGP’s unwillingness to provide a comment (which we understood why!)

It makes me think about what Elon Musk may have needed to work on for the final week of Plaid development. When he had announced that the event was going to be delayed a week due to “tweaks,” I wondered whether it was software or hardware. While it was likely a software fix that needed to be addressed, it could have been related to the drag coefficient, which Tesla proudly displayed at the Plaid Event on the 10th. Nevertheless, the vehicle has finally been released to pre-orderers, and the fastest production car that has ever run the 1/4-mile drag is here, and it’s taking down anything in its path.
A big thanks to our long-time supporters and new subscribers! Thank you.
I use this newsletter to share my thoughts on what is going on in the Tesla world. If you want to talk to me directly, you can email me or reach me on Twitter. I don’t bite, be sure to reach out!

Tesla FSD earns high praise in South Korea’s real-world autonomous driving test
As per the Korea Expressway Corporation’s report, the FSD test was conducted on December 15, 2025, from 10 a.m. to 6 p.m.
Tesla’s Full Self-Driving (FSD) has received a bullish assessment from the Korea Expressway Corporation following a real-world autonomous highway driving test.
A report of the test, shared on Naver Cafe, showed high praise for the system’s safety, capabilities, smooth maneuvers, and confidence.
South Korean highway test
As per the Korea Expressway Corporation’s report, the FSD test was conducted on December 15, 2025, from 10 a.m. to 6 p.m. Four people were in the Tesla that was tested, including the head of the mobility department. All four FSD driving modes were tested, from “Sloth” to “Mad Max.”
To test FSD’s performance, the system was tasked to operate on highways such as Gyeongbu, Cheonan, and Cheonan-Nonsan, as well as city areas in Dongtan New Town, Sejong Special City, and Daejeon Metropolitan City, among others.
Since FSD is only available for the Tesla Model S and Model X that are imported to South Korea from the United States, the system was not tested in a Model 3 or Model Y, which comprise the majority of Teslas on the country’s roads today.
Highway test results
Results showed FSD performing well, both in inner-city roads and on highways. In inner city roads, the testers noted that FSD was capable of autonomous driving at a level that already exceeds that of general human drivers, except in very few areas, such as unprotected left turns and work zone intersections.
In highways, the testers described FSD’s performance as “excellent,” though the system still showed frequent cases of violations in local bus lanes and max speed limit rules. These, however, could hopefully be addressed by Tesla in a future FSD update without many issues. The testers also noted that in some parts of the test, FSD seemed to be driving autonomously in accordance with traffic flow rather than strict traffic rules.

Tesla claims nearly 20% market share as Norway sets new car sales record
Tesla captured roughly one in five new cars in Norway, highlighting its dominance in the world’s most EV-friendly market.
Norway shattered its all-time new car sales record in 2025, and Tesla emerged as the clear winner. A year-end rush ahead of higher EV taxes pushed registrations to nearly 180,000 vehicles, with electric cars accounting for 96% of sales.
Tesla captured roughly one in five new cars in Norway, highlighting its dominance in the world’s most EV-friendly market.
Norway’s EV rush
As noted in a CarUp report, Norway’s electric vehicle sales in 2025 surged, thanks in part to buyers rushing ahead of a post–new year VAT increase of roughly 50,000 kronor on many new electric cars. This ended up pulling demand forward and setting a national record with almost 180,000 registrations in 2025.
The result was unprecedented. From the vehicles that were sold in 2025, 96% of new cars sold were fully electric. And from this number, Tesla and its Model Y made their dominance felt. This was highlighted by Geir Inge Stokke, director of OFV, who noted that Tesla was able to achieve its stellar results despite its small vehicle lineup.
“Taking almost 20% market share during a year with record-high new car sales is remarkable in itself. When a brand also achieves such volumes with so few models, it says a lot about both demand and Tesla’s impact on the Norwegian market,” Stokke stated.
Tesla domination
Tesla led all brands in Norway with 34,285 registrations, which is equal to a 19.1% market share. These results place Tesla well ahead of Volkswagen and Volvo, which held a 13.3% and 7.8% market share in 2025, respectively.
On the model chart, Tesla’s strength was even clearer. The Tesla Model Y topped all vehicles with 27,621 registrations, accounting for 15.4% of the entire market. The Tesla Model 3 also ranked among the top five, accounting for 3.7% of Norway’s entire auto sales in 2025.
Other strong performers included Volkswagen’s ID.4 and ID.7, Toyota’s bZ4X, which commanded 4.9%, 3.9%, and 4.1% of Norway’s total sales in 2025, respectively.

Tesla China sees 2nd-best month ever by selling 97,171 vehicles wholesale in December
The results mark Tesla China’s second-highest monthly result on record, trailing only November 2022’s 100,291 units.
Tesla posted a sharp year-end rebound in China last month, with December’s wholesale figures climbing to their second-highest level to date.
The surge capped a late-year recovery for the electric vehicle maker, even as full-year wholesale figures still finished lower year over year. Still, the data highlights how Tesla China’s offerings still resonate with customers in the world’s most competitive electric vehicle market.
Tesla China’s December surge
Tesla China sold 97,171 vehicles wholesale in December, as per data from the China Passenger Car Association (CPCA). The results mark Tesla China’s second-highest monthly result on record, trailing only November 2022’s 100,291 units, based on data compiled by CNEVPost. The details of Tesla China’s December results, such as its domestic sales and exports, are yet to be released.
December’s wholesale results represent a 3.63% increase from the same month last year and a 12.08% jump from November’s 86,700 units. It also marked the second consecutive month of year-over-year growth, signaling renewed momentum in China.
Tesla’s late-year momentum is believed to be partly driven by Tesla pulling deliveries forward to allow buyers to take advantage of more favorable purchase tax policies before the calendar year ended. That strategy helped boost monthly performance even as competition in China’s EV market remained intense.
Tesla China’s FY 2025 volumes
Despite the strong December finish, Tesla China’s wholesale sales declined on an annual basis. The electric vehicle maker’s total wholesale figures for 2025 reached 851,732 units, down 7.08% year over year. This could have been due to a variety of factors, from intense competition in the domestic Chinese market to Giga Shanghai’s changeover to the new Model Y in the early part of the year.
Tesla Gigafactory Shanghai continues to play a central role in its global operations, producing the Model 3 sedan and Model Y crossover for both Chinese customers and export markets. The efficiency of Gigafactory Shanghai has allowed it to become Tesla’s largest factory by volume, as well as the company’s primary vehicle export hub.
