Key Takeaways

The U.S. Department of Transportation is misusing its regulatory authority over fuel economy standards to push the Biden-Harris administration’s radical EV goals.

These abuses of executive power will have devastating economic consequences and will make our nation dangerously dependent on China.

The fact that NHTSA is pur­pose­fully sup­porting rules it knows will increase highway traffic deaths and injuries is shock­ing and ought to be a national scandal.

The Biden-Harris administration is yank­ing every lever of execu­tive power it can get its hands on to snuff out Americans’ love affair with the inter­nal-com­bus­tion engine (ICE).

The prime lever-puller is the Envi­ron­mental Pro­tec­tion Agency. In league with Cali­fornia’s cli­mate regu­lators, EPA is try­ing to force the auto indus­try to elec­trify new cars and trucks by dictating car­bon diox­ide emis­sions limits that are impos­sible for ICE vehicles to meet—some­thing Con­gress never auth­orized.

But EPA isn’t the only federal actor abusing its statu­tory auth­or­ities in further­ance of Presi­dent Biden’s elec­tric vehicle direc­tive. Under Pete Butti­gieg, the U.S. Depart­ment of Trans­por­ta­tion is throw­ing its weight into this coer­cive effort, too.

Acting through the National High­way Traffic Safety Admin­is­tra­tion, the Biden-Harris DOT has finalized two sets of “cor­por­ate aver­age fuel econ­omy,” or CAFE, stan­dards (mini­mum-mile-per-gallon require­ments for new ICE vehicles) that, perversely, can­not realis­tically be satis­fied with a tradi­tional gas-powered engine.

In the first of those two rules, finalized in April 2022, NHTSA replaced the fuel econ­omy stan­dards adopted by the Trump admin­is­tra­tion for vehicles pro­duced in model years 2024 through 2026 with gigantic increases. The replace­ment stan­dards man­dated pre­poster­ously huge annual jumps in fuel effi­ciency of 8% for each of model years 2024 and 2025 and 10% for model year 2026.

These increases in CAFE standards were meant to track the strin­gency of the car­bon dioxide limits for new motor vehicles EPA had begun to imple­ment in 2021—all in obe­di­ence to the Biden-Harris anti-fos­sil fuel agenda.

NHTSA’s 2022 rule required auto­makers to achieve aver­age fuel econ­omy levels of nearly 60 miles per gallon for pas­sen­ger cars and higher than 42 mpg for light trucks (including pick-ups, mini­vans, SUVs, and all-wheel-drive cross­overs). These mileage require­ments are pure fantasy. They can’t feasibly be achieved by the ICE vehicles that America’s families want and need and that they can afford to buy.

Under these standards, auto­makers will have to phase out the most popular models of cars and trucks and transi­tion their fleets to expen­sive EVs that so far don’t meet the budget and per­for­mance needs of most Americans—par­tic­u­larly not lower-income and rural families. The 2022 rule is cur­rently under legal challenge in the U.S. Court of Appeals for the D.C. Circuit.

The second Biden-Harris CAFE rule adds yet further increases to the fuel econ­omy require­ments beyond the levels imposed in the 2022 rule­making. The second rule covers pas­sen­ger cars and light trucks in model years 2027 through 2032 and medium-duty trucks (basically delivery vans and heavy work pick-ups) pro­duced in model years 2030 through 2035.

When this second rule was initially proposed in 2023, NHTSA planned to increase the strin­gency for pas­sen­ger cars by an addi­tional 2% per year for six years and for light trucks by a whopping 4% per year (in an effort to bring the mile­age stan­dards for pick-ups and SUVs closer to parity with the higher stan­dards applied to sedans and other smaller pas­sen­ger cars). For medium-duty work trucks, NHTSA pro­posed an incredibly strin­gent increase in fuel effi­ciency of 10% per year.

Again, these proposals were intended to stay direc­tion­ally con­sis­tent with EPA’s car­bon diox­ide restric­tions—at least to the extent NHTSA felt it could do so within the statu­tory para­meters of the CAFE pro­gram.

Just how extreme the stan­dards had gotten was evident from NHTSA’s 2023 notice of pro­posed rule­making. The agency pre­dicted that almost every legacy auto­maker would be unable to meet the new stan­dards, even with a rapid con­ver­sion to EV pro­duction, and, as a con­se­quence, would be forced to pay sizable pen­alties to the U.S. Trea­sury.

After getting strong push­back against the pro­posal in pub­lic com­ments, NHTSA decided to moder­ate the stan­dards when it final­ized the rule in June of this year.

For passenger cars, NHTSA kept the addi­tional annual increases at 2% through­out the period covered by the rule, but for light trucks, it reduced the increases to 0% for 2027-2028 and to 2% per year for 2029-2032. For medium-duty work trucks, it kept the final strin­gency increases at 10% per year for 2030-2032 but reduced them slightly to 8% per year for 2033-2035.

Predictably, the Biden-Harris admin­is­tra­tion has tried to spin these changes as a merci­ful “com­pro­mise,” granted by the grace of the almighty regu­lator, to “scale back” the require­ments of the CAFE program in light of eco­nomic and poli­tical realities.

However, this portrayal of NHTSA’s latest rule is dis­in­gen­u­ous for two rea­sons.

First, you have to remember that the modi­fied increases in the mile­age man­dates adopted in the 2024 rule would be piled on top of the already sky-high fuel econ­omy levels adopted in the 2022 rule. The 2022 stan­dards will be un­achievable for nearly all ICE vehicles pro­duced through 2026, and the later stan­dards, grow­ing in strin­gency from the 2026 stan­dards, will be even more un­achievable, despite the modu­la­tion in the rate of increase.

Even with the changes NHTSA made in the latest stan­dards, by 2032, those stan­dards would demand average fuel econ­omy per­form­ance of more than 72 mpg for pas­sen­ger cars and more than 47 mpg for pick-ups, SUVs, and other popu­lar light trucks.

There is simply no way auto­makers can possibly come close to meet­ing these fleet­wide aver­age mile­age stan­dards with­out shift­ing much of their pro­duc­tion to EVs, which are given arti­ficially gen­er­ous regu­la­tory credit for pur­poses of mea­suring CAFE com­pliance.

Inducing this industrial shift to elec­tri­fi­ca­tion has become the driving pur­pose of the CAFE pro­gram under the cur­rent admin­is­tra­tion.

Second, the tempering of the year-over-year increases in CAFE stan­dards for the later model-year vehicles is ren­dered effec­tively mean­ing­less, in any event, by EPA’s separate rules imposing even more dra­conian car­bon diox­ide emis­sions limits on those same vehicles.

That’s because putting regu­latory limits on the amount of car­bon diox­ide ICE vehicles produce per mile traveled (as EPA is doing) is functionally the same as setting mini­mum mile-per-gallon fuel econ­omy require­ments (NHTSA’s job in the CAFE pro­gram).

Therefore, the reality now, under the Biden-Harris admin­is­tra­tion, is that EPA has taken over the driver’s seat in setting fuel econ­omy require­ments for the nation’s fleet of new cars and trucks. That trans­fer of regu­la­tory power from DOT to EPA is directly con­trary to Con­gress’s design.

Congress made the decision nearly 50 years ago to give the Secre­tary of Trans­por­ta­tion, not EPA, the sole power to establish fuel eco­nomy stan­dards for new motor vehicles sold in the U.S. In carry­ing out that respon­sibility, NHTSA con­sults with EPA and the Energy Depart­ment, and EPA is tasked with mea­suring the auto­makers’ com­pliance with the stan­dards NHTSA sets, but neither EPA nor any other agency is sup­posed to super­sede or inter­fere with NHTSA’s CAFE authority.

The CAFE program was not created to be another form of environ­mental regu­lation. The pur­pose was to prod the auto­makers toward pro­duction of more fuel-effi­cient vehicle models to help lessen America’s stra­tegic depen­dence on foreign oil in the wake of the Arab oil embar­goes of the 1970s.

And in author­izing the program, Con­gress has always been very careful to limit NHTSA’s dis­cre­tion to impose overly strin­gent fuel econ­omy require­ments.

Congress’s goal all along has been to wean the U.S. of its strategic dependence on unreliable foreign sources of critical inputs like oil while (1) pre­serving the health and vitality of America’s job-sus­tain­ing auto­motive indus­try, and (2) ensuring that Americans will con­tinue to benefit from a wide range of affordable ICE vehicles that suit the needs of families in all income brackets in all regions of the country.

Consistent with those objectives, Con­gress expressly pro­hibits NHTSA from con­sider­ing the imputed fuel econ­omy of EVs in setting CAFE standards.

The bottom line is that NHTSA has no authority to compel the phaseout of inter­nal-com­bus­tion engines or require auto­makers to use new tech­no­lo­gies that are not responsive to market demand or that fail to align with the indus­try’s existing pro­duc­tion reali­ties.

So how is it that EPA has come to usurp NHTSA’s role in regulating fuel econ­omy, and why has the CAFE pro­gram been hijacked in support of the Biden-Harris EV man­date?

It was the Obama-Biden admin­is­tra­tion that originally launched EPA into the business of limit­ing car­bon diox­ide emis­sions from new vehicles under the Clean Air Act.

Recognizing the potential that EPA’s rules could improperly trample on NHTSA’s exclusive CAFE authority, the Obama admin­is­tra­tion had NHTSA and EPA join together to estab­lish a com­mon har­monized set of fuel econ­omy stan­dards and car­bon diox­ide emis­sions limits for each model year of new cars and trucks.

For its part, the Trump admin­istration con­tinued the prac­tice of having NHTSA and EPA issue a single joint rule to ensure harmoni­za­tion.

But now, in the name of pushing its thoroughly radi­cal­ized cli­mate policies, the Biden-Harris admin­istration has unleashed EPA, directing it to set car­bon diox­ide restric­tions at levels calcu­lated to achieve the White House’s EV goals with­out any regard for the care­ful limits Con­gress placed on the CAFE pro­gram.

Following the same marching orders, Pete Butti­gieg has instructed NHTSA to push the bounds of its own statutory authority to support and rein­force EPA’s actions.

The consequences of these regu­la­tory abuses will be nothing short of dev­as­tating for America.

The price of all new vehicles will rise dramatically, and America’s families will lose many of their favorite options at the dealer­ship. Lower-income and rural Americans will be stuck driving older and older used vehicles, which are far less safe, so highway deaths and serious injuries will rise.

NHTSA recognizes the negative safety effects of unreal­istically strin­gent fuel econ­omy require­ments, and yet it’s push­ing all these rules none­the­less. The fact that America’s pre­mier traffic safety regulator has pur­pose­fully sup­ported rules it knows will increase highway traffic deaths and injuries is shock­ing and ought to be a national scandal.

At the same time, countless jobs will be lost in the U.S. auto industry, while employ­ment surges in China, as the U.S. becomes des­per­ately depen­dent on China for the pro­duc­tion of criti­cal min­erals and other inputs needed for EVs—a national security danger anti­thetical to the pur­poses of the CAFE pro­gram.

Any artificially ramped-up transi­tion to elec­tric cars and trucks will also put a tre­men­dous strain on our fragile electricity grid and require a huge increase in power pro­duc­tion, just as the EPA has issued separate regu­la­tions designed to shut down fossil-fuel power plants. Elec­tricity prices will inevitably spike for all Americans as a result.

And even if it were fully carried out, the Biden-Harris admin­is­tra­tion’s Green Dream scheme will have no mean­ing­ful effect on global tem­per­a­tures because China’s pro­duc­tion of energy from dirty coal (con­sumed in grow­ing mea­sure to pro­duce ever more EV batteries) will just keep climb­ing.

It’s no wonder, then, that the wisdom of using the power of the admin­is­tra­tive state to coerce EV pro­duc­tion in the face of flagging market demand, with all the eco­nomic dis­rup­tions and destruc­tive con­se­quences that will inevitably follow from it, has become a highly charged public policy issue in 2024.
