Tesla had lowest tailpipe CO2 emissions & highest fuel economy in 2021 EPA Auto Trends report finds

Published

on

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 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.

Elon Musk has donated hundreds of generators to Tennessee residents still without power following a historic winter storm, as per an update from Governor Bill Lee. 

The donation comes as thousands of households have gone days without electricity amid freezing temperatures.

Musk donates generators

As noted in a report from WSMV4, the historic storm that hit Tennessee resulted in hundreds of thousands of residents experiencing a power outage at the end of January. Thousands are still living without power or heat in freezing temperatures for up to nine days.

As per TN Gov. Bill Lee in a post on X, Elon Musk and xAI have donated hundreds of generators to assist residents in affected areas. “Tennesseans without power need immediate help. I’m deeply grateful to @elonmusk & @xAI for going above & beyond to support Tennesseans by donating hundreds of generators to fill the gap, & I value their continued partnership to solve problems & support communities across our state,” he wrote in his post.

Tennessee officials have stated that recovery efforts remain ongoing as crews work to restore power and address damage caused by the winter storm. The generators are expected to provide temporary relief for residents facing power outages during freezing conditions.

Tesla Powerwalls may follow

Musk publicly responded to the governor’s post while hinting that additional help may be on the way. This time, the additional support would be coming from Musk’s electric vehicle company, Tesla. 

“You’re most welcome. We’re working on providing Tesla Powerwalls too,” Musk wrote in his response to the official. 

Even before Elon Musk’s comment, Tesla had already extended help to affected customers in Mississippi and Tennessee. In a post on X, the official Tesla Charging account noted that all Superchargers in the two states are online, and free Supercharging has been enabled to help those in areas that are affected by persistent power outages.

Tesla-inspired door handles prohibited under China’s new safety standard

The rule effectively ends a design trend pioneered by Tesla and widely adopted across China’s electric vehicle market.

China will ban hidden door handles on electric vehicles starting 2027 under a new national safety standard, forcing automakers to equip their cars with mechanical exterior and interior handles. 

The rule effectively ends a design trend pioneered by Tesla and widely adopted across China’s electric vehicle market.

China bans hidden door handles

China’s Ministry of Industry and Information Technology (MIIT) noted that the new mandatory national auto safety standard on EV door handles will take effect on January 1, 2027. For models that have already received approval and are scheduled for launch, automakers will be allowed to complete required design changes by January 2029.

Under the new rules, exterior door handles must remain operable even in scenarios involving irreversible restraint system failures or thermal runaway incidents in the battery pack. Doors must also be capable of opening even if the vehicle loses electrical power. Interior doors must include at least one independent mechanical release handle per door as well.

Safety concerns drive rollback

Hidden and electrically actuated door handles have become mainstream in recent years as EV makers pursued cleaner styling and improved aerodynamics. Tesla pioneered the hidden handle design, and it was adopted by most Chinese EV manufacturers in either fully hidden or semi-hidden forms, as noted in a CNEV Post report. Today, about 60% of top-selling EVs in China use the design.

Chinese regulators have stated that the designs pose safety risks, particularly in crashes or power failures where doors may not open from the inside or outside. Authorities cited multiple fatal incidents in which occupants or rescuers were unable to open vehicle doors after collisions.

One high-profile case occurred last October, when a Xiaomi SU7, a vehicle designed to be a competitor to the Tesla Model 3, caught fire following a crash in Chengdu in southwest China. The driver died after bystanders were unable to open the doors. The incident sparked intense scrutiny over the SU7’s Tesla-inspired door handles.

Reaching a global fleet of more than 9 million vehicles reflects the cumulative impact of Tesla’s growth over the past decade, particularly following the introduction of high-volume models such as the Model 3 and Model Y. The Model 3 and Model Y have allowed Tesla to transform from a niche automaker into one of the world’s largest producers of electric cars.

Strong China sales help drive fleet growth

Tesla’s expanding global footprint has been supported by solid performance in China, where the company posted a strong finish to 2025. In December, the Model Y ranked as the country’s top-selling new energy vehicle, as per sales data compiled by Chinese auto industry aggregator Yiche.

The Model Y led China’s NEV rankings with approximately 65,874 units sold during the month, outperforming a field dominated by domestic manufacturers such as BYD, SAIC-GM-Wuling, and Xiaomi. Tesla’s Model 3 also delivered an impressive result, ranking eighth overall with just under 28,000 units sold, ahead of numerous locally produced competitors despite its premium pricing.

Tesla China’s broader performance in December was equally notable. The company sold 97,171 vehicles wholesale during the month, based on data from the China Passenger Car Association. The result marked Tesla China’s second-highest monthly total on record, trailing only November 2022’s peak of 100,291 units.
