What You'll Learn
Diesel cars are more fuel-efficient than petrol cars
Diesel engines are also more durable and last longer than petrol engines. They are also more efficient for those who drive long distances or on highways. Diesel engines do not have spark plugs, but instead use extreme compression to generate the heat required for spontaneous ignition, also known as compression ignition. This process, if used in a petrol engine, would damage it.
Diesel engines are also more economical, as diesel fuel packs more energy per gallon than petrol fuel. However, diesel engines are also more expensive, heavier, and tend to have lower maximum RPM ranges than petrol engines. They are also less readily available than petrol engines, and diesel fuel system components can cost much more than their petrol counterparts.
Diesel engines have been more popular in Europe than in the US, due to historically lax emissions standards in Europe, the failure of US carmakers to make reliable diesel cars in the 1970s, and the fact that diesel engines are noisier and produce more pollution. Gas is also more expensive in Europe, and diesel engines get better gas mileage.

Diesel engines are noisier and more polluting
Diesel engines have a reputation for being noisier and more polluting. This is partly due to the relaxed emissions standards in Europe compared to the US, where diesel vehicles must meet the same standards as gasoline vehicles.
Diesel engines emit less CO2 and greenhouse gases than petrol engines. This is due to the higher compression ratio of diesel fuel, which results in better performance and less fuel used to travel the same distance. However, diesel engines require large amounts of air for fuel combustion, which causes more chemical reactions and releases air pollutants such as nitrogen oxides and fine particles. These fine particles are associated with poor heart health, leading to more hospital admissions and deaths from heart attacks.
While diesel engines were initially less efficient than petrol engines in terms of fine particles, manufacturers have since installed particulate filters to meet new, more restrictive standards. These filters can remove up to 99% of diesel polluting mass particles. However, they cannot retain the finest and largest particles produced by diesel engines, and they tend to clog up in urban areas where diesel engines are primarily used.
The focus on reducing CO2 emissions in Europe, rather than local pollution, has contributed to the popularity of diesel engines on the continent. Diesel engines were promoted as a more environmentally friendly option following the 1997 Kyoto Protocol, which aimed to reduce greenhouse gas emissions. This led to governments incentivizing the purchase of diesel vehicles with subsidies, tax breaks, and other policies.
In summary, while diesel engines may be more fuel-efficient and produce less CO2 than petrol engines, they contribute to air and noise pollution, particularly in urban areas. The complex nature of engine technologies and evolving standards makes it challenging to definitively state which type of engine is more polluting. However, the negative health impacts associated with fine particulate matter emitted from diesel engines are a significant cause for concern.

Diesel cars are more popular in Europe than in the US
Furthermore, diesel cars have been promoted by European governments, including the UK and Norway, due to their lower carbon dioxide (CO2) emissions, which are taxed more heavily than other emissions. Road tax breaks and subsidies were introduced to incentivise the purchase of diesel vehicles. However, this trend is shifting as governments and consumers become increasingly concerned about the other noxious gases produced by diesel engines.
Additionally, emissions standards in Europe have been less stringent than those in the US, which has made diesel cars more attractive to European consumers. Diesel vehicles in the US must meet the same emissions standards as gasoline vehicles, which can be challenging due to the differences in engine design. The extra emissions equipment required for diesel cars to comply with US emissions standards can reduce their fuel economy, making them less appealing to American consumers.
Cultural habits and driving patterns may also play a role in the differing popularity of diesel cars between the two regions. Americans, on average, drive longer distances and tend to "load up" their vehicles with a week's worth of supplies. The perception of diesel cars as underpowered and struggling to reach freeway speeds could be a contributing factor to their lower popularity in the US.

Diesel is cheaper than petrol in Europe
Diesel-powered cars are more common in Europe than in the United States, where gasoline tends to be the fuel of choice. One reason for this is that diesel has historically been cheaper than petrol in Europe. As of 2009, diesel was cheaper than petrol in the following European countries: Belgium, Denmark, Finland, France, Germany, the Netherlands, Ireland, Italy, Luxembourg, Lithuania, Poland, Slovenia, Portugal, Sweden, and Bulgaria. However, by 2022, diesel had become more expensive than petrol in most EU countries, with Sweden exhibiting the largest price difference.
There are several reasons why diesel has been cheaper than petrol in Europe. One factor is taxation policies. Lower taxes were historically used to promote the use of diesel, and while many countries are now reducing taxes on fuel to provide relief from rising prices, these tax differentials still exist in many places. For example, in Sweden, diesel is taxed 13 percentage points less than petrol, and in Greece, the difference is 12 percentage points.
Another factor contributing to the lower price of diesel in Europe is the region's emissions standards. European emissions standards have been more relaxed than those in the US, which are fuel-agnostic. Diesel vehicles in the US must meet the same stringent emissions standards as gasoline vehicles, which is challenging due to diesel's higher emissions. Europe, on the other hand, has prioritized the reduction of CO2 emissions, in which diesel vehicles excel compared to their gasoline counterparts. However, diesel vehicles produce more local pollution, and it has been revealed that many diesel manufacturers lied about their local pollution levels, leading to a lack of concern from governments.
The failure of US carmakers to produce reliable diesel cars in the 1970s also played a role in diesel being more affordable in Europe. The US's emphasis on fuel economy and freeway speeds, combined with the unavailability of diesel at gas stations, contributed to the underpowered nature of early diesel cars in the American market. Additionally, diesel engines are known for being noisier and producing more smoke, making them less appealing to consumers.

Diesel cars are more common in Europe's used-car market
Secondly, diesel engines offer better fuel efficiency, especially when paired with heavier vehicles like SUVs. The torque and performance of diesel engines can offset the weight of larger vehicles, resulting in improved fuel efficiency compared to petrol engines. This advantage is particularly appealing to consumers who prioritize spacious and comfortable designs.
Another factor is the historical context of emissions policies and taxation in Europe. European emissions standards have been more relaxed for diesel vehicles, focusing primarily on reducing CO2 emissions. This led to the marketing of \"clean diesel," emphasizing lower CO2 emissions. Governments, such as in the UK, also previously subsidized diesel and offered tax breaks due to its perceived environmental benefits. These factors made diesel vehicles more affordable and desirable to consumers.
However, it's important to note that the popularity of diesel cars in Europe's used-car market may not persist indefinitely. With increasing awareness of the environmental concerns associated with diesel, such as local pollution and NOx emissions, the demand for diesel vehicles in the new-car market has decreased. As a result, the supply of used diesel cars is also expected to decline over time.
Additionally, the price of diesel fuel has recently surpassed that of petrol for the first time, impacting the cost-effectiveness of diesel vehicles. While diesel cars remain profitable outside city centers due to their fuel efficiency, the increasing fuel prices may deter some buyers.
