Diesel engines took a huge, disgraceful hit when Volkswagen was exposed for installing software on its vehicles designed to cheat emissions tests. But the fact remains that diesels are more efficient than gasoline engines—and according to one recent study, newer models are cleaner, except for their higher emissions of nitrogen oxides. This problem has led to heavily decreased sales of diesels in Europe, while some big cities such as Paris are now planning to ban diesels. Meanwhile, sales of all-electric and hybrid cars are rapidly increasing in Europe.
