The popularity of SUVs is rising, with SUVs accounting for half of all vehicles sold in the US, 44% in China, and 36% in Europe. However, this trend is detrimental to fuel efficiency and efforts to reduce emissions. SUVs are generally 15-30% less fuel-efficient than sedans due to their weight and wind resistance, which requires more powerful and fuel-thirsty engines. While some SUVs, especially crossovers, have improved fuel economy, they still fall short of the efficiency of smaller cars. To improve overall fuel efficiency and reduce emissions, there needs to be a shift towards more fuel-efficient cars or electric and hybrid vehicles, rather than a continued focus on producing and purchasing SUVs.

SUVs are less fuel-efficient than sedans, which are shorter, weigh less, and are more aerodynamic
The popularity of SUVs is a significant roadblock to improving fuel efficiency in the automotive industry. SUVs are generally 15-30% less fuel-efficient than sedans, the prototypical passenger car. This is primarily because SUVs are heavier and less aerodynamic than sedans.
Sedans are shorter, weigh less, and are more streamlined than SUVs. This gives them an inherent advantage when it comes to fuel efficiency. The first SUVs were based on truck-style ladder frames, making them quite heavy. They also required powerful, fuel-thirsty engines to move all that weight. While SUVs have become more fuel-efficient in recent years, they still have a long way to go to catch up to sedans.
The cargo room of many SUVs can lead to the accumulation of unnecessary items, increasing weight and wind resistance. Removing unused cargo and opting for more fuel-efficient models, such as hybrids or electric vehicles, can help improve fuel economy. However, it is worth noting that even the most fuel-efficient SUVs are still less efficient than sedans due to their inherent design differences.
The popularity of SUVs is driven by consumer preferences and profitability for automakers. Between 2010 and 2019, the share of SUVs in overall car sales in China jumped from 14% to 44%, while in Europe, it climbed from 10% to 36%. This trend is negating the annual fuel efficiency gains from technological advancements and tightening fuel economy standards.
While some SUVs are now on par with large cars in terms of fuel economy, the overall fuel efficiency of the automotive industry is declining due to the decreasing sales of smaller, more fuel-efficient cars. This shift in consumer preferences and production priorities is detrimental to the goal of reducing global emissions from cars.

SUVs are becoming more popular, with sales increasing in the US, China, and Europe
SUVs are becoming increasingly popular, with sales of these vehicles rising in the US, China, and Europe. In 2023, SUVs accounted for 48% of global car sales, setting a new record. This trend continued into 2024, with China leading SUV sales, followed by the US, India, and Germany.
There are several reasons for the growing popularity of SUVs. One key factor is the marketing and advertising campaigns of automobile manufacturers, who have a strong financial incentive to promote SUVs. SUVs are generally more profitable for automakers, as they can charge more for these vehicles, even though they may produce fewer overall. The demand for SUVs has been rising, with consumers increasingly attracted to dual-purpose vehicles that offer practicality, comfort, and improved visibility on the road. The availability of SUV alternatives in smaller sizes has also contributed to their popularity, particularly in Europe, where sales of these smaller SUVs have grown significantly.
While SUVs are gaining traction, their rise in sales is setting back efforts to improve fuel efficiency and reduce emissions. SUVs are typically 15-30% less fuel-efficient than the average passenger car, and their increasing presence on the road is negating the annual gains in fuel efficiency from technological advancements. The trend towards heavier and less efficient vehicles, such as SUVs, has largely offset the progress made in reducing energy consumption and emissions in the global passenger car fleet. This is particularly notable in the US, where SUVs likely accounted for half of all vehicles sold in recent years, and in China, where the SUV share of overall car sales jumped from 14% to 44% between 2010 and 2019.
Despite the challenges posed by the increasing popularity of SUVs, there have been some improvements in fuel efficiency within this vehicle category. Crossovers, which are lighter and more fuel-efficient than traditional SUVs, have driven much of the growth in SUV sales. Additionally, advancements in construction methods and powertrain technology have made SUVs more efficient than ever before, with some models now offering fuel economy comparable to large cars.

SUVs are getting bigger, which puts consumer choice at odds with climate concerns
SUVs are increasingly becoming the world's pre-eminent car, spreading from the US to China to Europe. This shift towards SUVs is challenging efforts to reduce emissions and is putting consumer choice at odds with climate concerns.
The rise of SUVs is producing a vast new source of planet-cooking emissions. SUVs require more energy to move around than smaller cars and therefore emit more CO2, overshadowing the car industry's climate gains from fuel efficiency improvements. In the US, SUVs emit 14% more carbon dioxide than small passenger cars on average. Over a 15-year lifespan, the SUVs sold in the US in 2018 will emit 429.5 million tonnes of CO2. SUVs are the second-biggest cause of the rise in global carbon dioxide emissions during the past decade.
SUVs are generally around 15-30% less fuel-efficient than the prototypical passenger car, the sedan. Auto manufacturers have a strong incentive to push consumers towards SUVs because the profit earned per vehicle sold is higher for SUVs than for sedans. To lure more buyers, car companies have introduced a greater variety of new choices of SUVs than they have for sedans and other passenger cars.
While it is true that vehicles are increasing their fuel efficiency every year, with electric ones on the way, they are also getting bigger and bigger. This puts consumer choice on a collision course with concerns over the climate.
However, it is important to note that individual actions are no substitute for corporate and government leadership. While SUVs are certainly contributing to the climate crisis, the choices made by corporations and governments will have a much more significant impact on global warming and air pollution.

SUVs are more profitable for auto manufacturers, who have introduced a wider variety of models
SUVs are more profitable for auto manufacturers for several reasons. Firstly, they have higher profit margins due to their higher demand. Manufacturers can charge more for larger vehicles, and the profit earned per vehicle sold is higher for SUVs than for smaller cars. This is partly because of the artificial scarcity created by CAFE standards, which limit the number of larger vehicles that can be sold, driving up prices and profit margins.
Another factor contributing to the profitability of SUVs is the customer lifetime theory. Manufacturers aim to get loyal customers who will upgrade to bigger and more expensive vehicles over time. By offering a wider variety of SUV models, manufacturers can attract more buyers and increase their profits. This strategy is evident in the introduction of new choices and features in SUVs, such as improved aerodynamics, spacious cabins, advanced technology, and fuel-efficient powertrains.
While SUVs are becoming more fuel-efficient due to advancements in technology and tightening fuel economy regulations, they still lag behind smaller cars in terms of fuel efficiency. The average fuel efficiency improvements of light-duty vehicles have slowed down, and the growing popularity of SUVs is negating the gains made by better technology. Therefore, while SUVs may be more profitable for auto manufacturers, there is a need to balance profitability with environmental concerns and fuel efficiency improvements.
