European cars are often considered more fuel-efficient than their American counterparts due to various factors. One key reason is the prevalence of smaller vehicles and diesel engines in Europe, which are inherently more fuel-efficient than larger gasoline engines. Additionally, European tests for fuel efficiency differ from American tests, with the former being shorter and slower, and not necessarily reflecting real-world driving conditions. Furthermore, the measurement units for fuel efficiency differ between Europe and America, with European figures measured in litres of fuel used per 100 kilometres, while American measurements are based on distance per fuel quantity. These differences in testing methods and measurement units contribute to the perception of higher fuel efficiency in European cars.
| Characteristics | Values |
|---|---|
| Fuel type | European cars tend to use higher-octane petrol and lower-sulphur diesel, whereas US cars use lower-octane petrol and higher-sulphur diesel. |
| Engine size | European cars typically have smaller engines (under 2.0 litres) compared to US cars (over 2.5 litres). |
| Fuel efficiency standards | The US has stricter emissions regulations, which can make diesel cars less appealing to consumers due to higher costs and the need for urea injection systems. |
| Testing procedures | European tests, such as the New European Driving Cycle, are shorter and slower than US tests, which may include higher speeds and additional variables like air conditioning and cold temperatures. |
| Measurement units | European fuel efficiency is measured in litres of fuel per 100 kilometres, while US measurements are based on distance per fuel quantity and use smaller gallons than the UK. |
| Market preferences | The European market favours smaller, more fuel-efficient cars, while US consumers prefer larger vehicles with more powerful engines due to cultural and geographical factors. |

What You'll Learn
Smaller vehicles are more popular in Europe
There are several reasons smaller vehicles are more popular in Europe. Firstly, European cities are much more compact than American cities, with smaller parking spaces that cannot accommodate large vehicles. In addition, the price of gasoline and diesel is much higher in Europe, leading people to buy highly fuel-efficient vehicles, which tend to be smaller. Europe's gasoline prices vary by country, but they are generally very high relative to the United States. For example, as of April 2020, the price of gasoline per gallon in Oslo, Norway, was $6.27, while the average price per gallon in California was around $4.
Furthermore, European countries and cities have strict emissions requirements, and large, gas-guzzling vehicles are unlikely to meet these standards. Western Europeans also tend to value moderation, which is reflected in their preference for smaller cars, servings at restaurants, coffees, and houses. Additionally, per capita income in European countries tends to be lower than in America, so Europeans have less money to spend on larger, more expensive vehicles.
The small cars market in Europe is expected to grow, with unit sales projected to reach 2,721,000 vehicles in 2029, and a market volume of US$44,570,000,000. This popularity of smaller cars in Europe contributes to the overall fuel efficiency of the European vehicle fleet.
It is worth noting that the difference in fuel efficiency between Europe and the United States is also attributed to variations in testing procedures and regulations. European tests, such as the ""Urban" test, are often shorter and slower than those in the US, which can impact the reported fuel efficiency of vehicles.

European tests are unrealistic and don't reflect real-world results
There are several reasons why European cars are considered more fuel-efficient than their American counterparts. Firstly, the types of cars and engines differ between the two markets. The European market has a greater variety of smaller, more fuel-efficient cars with smaller engines, while larger vehicles with bigger gasoline engines are more prevalent in the US. This is partly due to cultural and historical factors, as the US has typically had cheaper fuel, more available land, and a heavy industry presence, making larger engines a simple and cost-effective way to increase power.
However, a significant factor in the perceived fuel efficiency discrepancy is the difference in testing procedures and measurements between the two regions. The New European Driving Cycle's test procedure is shorter and slower than the US Environmental Protection Agency's (EPA) procedure. For example, the European "Urban" test is 13 minutes long, while the EPA's city test is 31 minutes long. The EPA's test also includes higher speeds and accounts for real-world factors such as high speed, air conditioning, and cold temperatures, making it more reflective of actual driving conditions.
Furthermore, it has been noted that European tests are unrealistic and do not accurately reflect real-world results. The testing procedures are considered to be far from reality, with a significant difference between the lab results and the actual fuel economy experienced by drivers. Additionally, automakers have been known to exploit loopholes in the European testing procedures, further blurring the lines between rated efficiency and real-world performance.
The difference in fuel efficiency measurements between Europe and the US also contributes to the perception of higher fuel efficiency in Europe. European figures are measured in litres of fuel used per 100 kilometres, while North American measurements use the inverse, calculating distance per fuel quantity. When converting European measurements to the more familiar miles per gallon (MPG) measure, it is important to note that Imperial gallons, used in the UK, are 20% larger than US gallons. This means that an "80-mpg" European car would actually be closer to 67 mpg, and in reality, may not achieve this due to the unrealistic nature of the tests.
In summary, while there are some differences in the types of cars and engines commonly found in Europe and the US, the perceived higher fuel efficiency of European cars is largely due to unrealistic testing procedures and differences in measurement systems.

European cars have smaller engines
European cars are often more fuel-efficient than their US counterparts due to several factors, one of which is engine size. European engines tend to have smaller displacements compared to American engines. The average engine size in Europe falls between 1.3 and 1.9 litres, with some as small as 1 litre. In contrast, an average European V8 engine is around 4-4.5 litres, while American V8s typically come in at 6 litres.
The preference for smaller engines in Europe can be attributed to various factors, including fuel prices, taxes, laws, smaller roads, and insurance costs. Europe tends to have higher fuel prices, with gasoline costing between $6 and $9 per gallon. Additionally, many European countries had registration taxes based on engine displacement, and while some have shifted to CO2 emissions-based taxes, these can also incentivise smaller engines.
European roads also tend to be narrower and less highway-focused, making smaller cars more manoeuvrable and efficient. Insurance costs are another factor, as premiums increase with larger engine displacements. Furthermore, European automakers have engineered quality small-displacement engines, utilising efficient turbochargers that offer 7.0-litre performance from a 4.0-litre engine.
However, it's important to note that the era of small engines in Europe may be coming to an end due to emissions regulations. Smaller gasoline engines can struggle with fuel efficiency and emit high levels of fine particles and carbon monoxide. As a result, automakers are rethinking their strategies to meet stricter emissions standards, and larger engines may become more prevalent.

US fuel is cheaper, so less incentive to be efficient
Fuel efficiency is a significant concern for many countries, and governments have implemented various policies and incentives to encourage the adoption of fuel-efficient vehicles. One notable difference between the United States and Europe is the relative cost of fuel. In the United States, fuel prices are generally lower than in Europe, which reduces the incentive for consumers to prioritize fuel efficiency when purchasing a vehicle.
The lower fuel prices in the United States can be attributed to various factors, including different taxation policies and the country's significant oil production capabilities. While cheap fuel may benefit drivers in the short term, it can also reduce the urgency to transition to more sustainable transportation options. As a result, there is less incentive for both consumers and manufacturers to invest in fuel-efficient vehicles.
In contrast, European countries have historically experienced higher fuel costs, prompting a stronger emphasis on fuel economy in the automotive market. This market pressure has driven the development and adoption of more fuel-efficient vehicles, such as smaller cars with diesel engines, which are more prevalent in Europe than in the United States.
It is worth noting that the United States has also taken steps to promote fuel efficiency. At the federal level, tax credits and incentives have been introduced to encourage the purchase of low-emission and fuel-efficient vehicles. Additionally, individual states have implemented their own incentive programs, including discounts on insurance, reduced car registration fees, and free parking for electric vehicles.
However, the impact of these incentives can be diminished when fuel prices remain relatively low. Higher fuel prices can act as a more immediate and tangible incentive for consumers to reduce their fuel consumption or invest in more fuel-efficient vehicles. This dynamic illustrates the complex interplay between market forces and policy interventions in shaping the fuel efficiency landscape in both the United States and Europe.

Different fuel types are used in Europe and the US
While the fuel quality in the US is as good as anywhere else in the world, including Europe, there are some differences in the fuel types used in the two regions. Firstly, the way fuel quality is described differs between the US and Europe. In the US, the quality of gasoline is described using octane numbers, which are determined through experimental tests. However, the US uses a different system for octane numbers that does not translate directly to the octane numbers used in Europe and the rest of the world. For example, US 91 octane fuel is equivalent to European 95 octane fuel.
In Europe, fuel quality is described using the Research Octane Number (RON) rating system, which is also used in most other parts of the world. Gas stations in Europe typically offer fuel with RON ratings of 100, 99, 98, 97, or 95, with prices varying accordingly. Higher octane petrol is more common in Europe, while the US tends to use lower octane fuels. Additionally, diesel fuel in Europe has a lower sulphur content than in the US, which can impact fuel consumption and engine performance.
Another difference is the prevalence of diesel engines in Europe compared to the US. Smaller vehicles and diesel engines are more common in Europe, and these vehicles tend to be more fuel-efficient than larger vehicles with larger gasoline engines, which are more prevalent in the US. The emphasis on fuel economy is higher in Europe, and cars with smaller engines and diesel options are favoured due to their efficiency. However, it is important to note that diesel engines in Europe may have higher nitrogen oxide emissions, which can contribute to air pollution.
Furthermore, the testing procedures for fuel efficiency differ between Europe and the US. The New European Driving Cycle (NEDC) test used in Europe is shorter and slower than the test procedure used by the US Environmental Protection Agency (EPA). The NEDC includes an "Urban" test that is only 13 minutes long, while the EPA's city test lasts for 31 minutes and involves higher speeds and more acceleration and deceleration. These variations in testing procedures can lead to discrepancies in fuel efficiency ratings between the two regions.
