The electric vehicle revolution is on the rise: In 2021, global passenger EV sales increased by 103 percent. They accounted for 13 percent of all new vehicle sales in the fourth quarter of 2021.

Many more EVs are being developed. Ford just delivered the first electric F-150 truck to a rural Michigan customer. It is the most popular vehicle in America. Ford intends to invest $25 billion into EVs by 2025. General Motors currently has two Bolt versions for sale and plans to start delivering its Hummer Electric Vehicle (EV) this fall. GM plans to invest $27 billion in EVs by 2025 and all-electric by 2035.

The summer road trip season begins and gasoline prices hit record highs, making it more attractive to drive without gas than ever. This year could be a turning point in the history of the number of road-going internal combustion engines. Countries such as Finland and Germany, and New Zealand, have plans to completely eliminate gasoline vehicles.

While many car companies are aiming for a future full of electrons, it is their traditional cars that will have the most impact on the global climate. The largest source of carbon dioxide in the US is transportation. 60% of that share goes to cars and light trucks. President Joe Biden made a commitment to reduce US emissions 50-52% below 2005 levels by 2030. This would require huge reductions in emissions from cars and trucks, as well as pickup trucks and crossover SUVs.

However, electric cars still represent 3 percent of all new car sales in America. The average car is on the road for over 11 years. This means that electric vehicles may only make up 13 percent of all US cars by 2035. Even though electric vehicles are rapidly growing in popularity, it will still take them years before they catch up with gasoline and diesel cars.

To meet climate change goals, a more gradual and less glamorous approach is required: Increasing efficiency. This requires regulations that the auto industry, oil companies, and some states have long resisted.

“Efficiency regulations remain really important even though automakers make pledges to electrify fleets,” stated Kate Whitefoot a Carnegie Mellon University associate professor of engineering policy.

California is a pioneer in setting pollution targets for vehicles. This has forced automakers to meet increasingly difficult benchmarks. This privilege has been held by the Golden State for decades because of a legal tidbit. 17 Republican state attorneys general sued earlier this month to stop the Environmental Protection Agency’s upholding of California’s special status. The suit, if successful, could halt progress towards more efficient cars or trucks.

There are also other obstacles. Americans still love big cars. The cost of new cars is increasing. Inflation and supply chain problems are making it more difficult to purchase new cars, including electric vehicles because the economy is stable. It’s making it difficult for carmakers to plan ahead. They want certainty. That’s why some carmakers are working harder to maintain their fleets, as required by regulations, using EVs and increasing efficiency.

Why California’s car regulations are so important to the country

California has historically been exempted from federal regulations regarding emissions from cars and light-duty trucks, as per the Clean Air Act. Sacramento enjoys the same privilege as Washington in regulating pollutants that come out of tailpipes. This includes particulates and nitrogen oxides.

It is important to remember that although vehicle emissions and fuel economy are closely linked, they are not the same thing. Different agencies regulate them. California can set standards for air pollution, but only the federal government, namely the Department of Transportation’s National Highway Traffic Safety Administration, can set fuel economy rules.

Since 1990, California has established a mandate for zero-emission vehicles. This requires that manufacturers sell a specified number of plug-in hybrids and battery-electric cars. California has been a leading laboratory for the regulation of cars and trucks.

“California gets the chance to experiment,” stated Meredith Hankins a senior lawyer at the Institute for Policy Integrity of the New York University School of Law. “They can kind of be the first to explore how we can reduce our emissions.”

The federal government often looks at California’s implementation of car regulations and uses its experience to help create new national regulations. California is the nation’s most populous state with the largest auto market. This means that it can set the standard for the rest of America even before the federal government can.

California Air Resources Board is currently updating its regulations regarding clean cars. The proposal by the agency again targets a higher standard for pollution than that of the federal government. The agency also wants to increase zero-emission vehicles and trucks sold in the state. Vox spoke with David Clegern, a spokesperson for CARB, who said that, unlike California, the federal government doesn’t have any requirement for zero-emission vehicle sales.

And 17 other states have already adopted California’s standards for vehicle pollution. Instead of redesigning vehicles for every state, car companies use the California benchmarks for the entire country.

This special status was not a good fit for some, including former President Donald Trump. He removed California’s authority set its own emission standards. In March, President Joe Biden reinstated the waiver.

The EPA was then stopped from restoring California’s special state status by Republican attorneys general representing those 17 states. They argued that this gives California an unfair market advantage and increases the cost of cars. A group of 20 additional states and the District of Columbia voted in favor of the status being maintained.

Although it’s difficult to predict where litigation will lead, courts have always upheld California’s special status. Hankins stated that “it’s a very established provision, and now the red states are arguing it’s unconstitutional.”

The federal government updated its vehicle efficiency standards this year. These are known as Corporate average fuel economy (CAFE) standards. The new standards require that the US auto industry average 49 miles per gallon in its fleet by 2026. This is up from the 28 mpg benchmark. The new rules, according to the Transportation Department will reduce fuel consumption by more than 200 billion gallons over 2050 than the current standard.

“These improvements will also make the country less vulnerable to global shifts of the price of oil and protect communities by reducing carbon emission by 2.5 billion metric tons,” said Transportation Secretary Pete Buttigieg in an April Statement.

It is an enormous relief for the $100 million US auto industry that any standard has been established. Whitefoot stated that uncertainty in itself can have a significant impact on the industry’s long-term R&D planning. It can take many years to design a car. Companies have trouble getting cars in the showroom if they keep moving the goalposts. Some car companies have fought federal regulations and California’s waiver, but they are now waiting for the dust to settle quickly.

Although automakers are experts at building cleaner and more efficient vehicles, will they be able to sell them to the public?

It is clear that electric cars are the future of the global automotive industry. Toyota, the largest carmaker in the world, has invested $17.6 million to develop a line of 30 electric cars by 2030. Mercedes plans to launch 10 new electric vehicles this year. Nissan intends to launch eight EVs before the end of 2023. Between now and 2025, big EV launches are planned for Acura, Audi and BMW, Honda and Land Rover, Toyota, and Volkswagen, as well as Toyota and Volkswagen.

There are also car companies that only make EVs like Lucid, Polestar, and Rivian. The most valuable automobile company in the world was the Tesla EV manufacturer.

However, car companies still have plenty of room to improve their gasoline and diesel offerings. Many are already using new technologies in order to improve the efficiency of their fleets. According to the National Academies, “Electric Hybridization is the best efficiency option for gasoline-fueled vehicles.” A report from last year’s National Academies stated that this was the case. The hybrid synergies can make the internal combustion engine more efficient.

There are many systems that combine electric motors with gasoline engines. These systems include acceleration assist systems, automatic stopping and starting engines at stoplights, and plug-in hybrids that can run entirely on gasoline or electricity. Automakers can increase the compression ratios of engines while increasing fuel efficiency can be achieved by adding more gears to transmissions. Aerodynamic improvements and lighter materials such as aluminum can help cars travel farther with less fuel.

Americans want more legroom, more ground clearance, more power, and more space. This in turn requires more energy to move about. According to the EPA’s automotive trend report, this has “offset some fleetwide benefits that would otherwise have been achieved through the improvements within each vehicle type.” Even electric cars are becoming larger, which is affecting their performance.

Because they have higher margins, carmakers like to make larger cars. Ford stated in 2018 that it would no longer make sedans and instead focus on trucks, SUVs, crossovers, and other vehicles.

It’s an incentive to produce larger cars since fuel economy regulations are based on the size of the vehicle. This has helped to create new types of vehicles such as the cross-over. It is a taller and heavier vehicle that is built on a car platform, in contrast to sport utility vehicles which are usually built on truck platforms. Crossovers account for half the cars sold in America. Ford’s Electric Mustang is now an SUV.

Larger cars are also more costly. The average car purchased in the US is now more than $47,000. The US median income is $41,000 and 85 percent of new car purchases are made with loans. The US’s automotive debt is now at $1.4 trillion. Transportation is the second-largest expense in most households after housing. In fact, for most Americans, driving is not an option. As a result, people are driving more.

Big cars can be dangerous for those who are not in them. More pedestrian deaths have been caused by larger vehicles. These vehicles are especially dangerous for children because they often have large blind spots. They are safer for drivers and passengers than smaller cars.

This has made it harder for people to purchase new, more efficient vehicles or electric cars. Also, the vehicles aren’t as safe or clean as they could be.

Some lawmakers called for discounts from the government to encourage people to switch to EVs. The Biden administration also invests in infrastructure to support cleaner cars, including $7.5B to construct 500,000 EV charging stations throughout the country and close enough to $10B to support hydrogen fuels in vehicles.

To reduce greenhouse gas emissions, cars must be made more affordable to replace older cars. This will require a broader reimagining of transportation. The US has approximately 75 percent of all vehicle trips that are shorter than 10 miles. This is an enormous opportunity to explore alternatives to driving, such as scooters, cycling, public transit, and car-sharing.

While electric vehicles might be the future of the automobile industry, there are many obstacles and bumps in the road. Carmakers will continue to stay on the right track by improving fuel efficiency.
