U.S. and U.K. retail prices of diesel fuel

The usage of diesel began in the 1930s, but until further European development in the 1960s, diesel vehicles were mostly applied to commercial use only. More recently, diesel-fueled engines have become more popular as diesel engines become more efficient. In the United Kingdom, 26.6 percent of new cars registered in 2019 were fueled by diesel. This is a noticeable decline from the 42 percent market share that diesel vehicles held in the U.K. in 2017. In the United States, diesel-powered cars remain a fairly small portion of the automobile market. Diesel cars often have lower acceleration, higher costs, and a heavier weight. They may also be more difficult to start in cold weather. Gasoline also tends to be more widely available than diesel fuel. However, diesel engines have better fuel economy than that of gasoline engines, and tend to last longer as well.
