Why don’t more people drive diesel?
Many consumers of diesel trucks hated the newer technologies due to the increased maintenance costs, lower torque ratios and reduced horsepower. Today those problems have been solved and in fact emissions technology has been shown to increase horsepower and engine efficiency output.
What are the advantages and disadvantages of diesel engine in passenger car?
Because it contains more usable energy than gasoline, it delivers better fuel economy. Diesels have no spark plugs or distributors. Therefore, they never need ignition tune-ups. Diesel engines are built to withstand the rigors of higher compression.
What is wrong with diesel cars?
The nitrogen oxides (NOx) produced by diesel engines are one cause of air pollution.
Are diesel cars slower?
Diesel engines are generally heavier than their petrol counterparts making them slower. As a consequence of a higher compression ratio (longer stroke), diesel engines produce more torque which means you get more acceleration off the line.
What is the disadvantage of buying a diesel car?
Some other downsides to diesel are: Increased cost. Diesel is more expensive to buy at the pump than petrol, and the higher purchase price of a diesel car can bump up insurance costs. New diesel cars also cost more to tax.
What happens to diesel cars after 10 years?

Why don’t more passenger cars have diesel engines?
Diesel engines have never really caught on in passenger cars. During the late 1970’s, diesel engines in passenger cars did see a surge in sales because of the OPEC oil embargo (over half a million were sold in the U.S.), but that is the only significant penetration that diesel engines have made in the marketplace.
Why are there no diesel cars and pickups in the US?
The fact that diesel cars and pickups are not marketed, sold, nor purchased in the United States is shocking considering the advantages of diesel engines. Diesel engines can last twice as long as a spark-fired gasoline combustion engine.
Are diesel engines more environmentally friendly than gasoline engines?
Second, diesel engines are considerably more environmentally friendly than gasoline engines. The fact that diesel cars and pickups are almost non-existent in the United States is puzzling. The lack of diesel cars and pickups in the United States is especially odd when considered in relation to the other continents and countries around the world.
Why is diesel taxed higher than gasoline in the US?
But in the United States, for some reason, diesel is taxed higher. Even though diesel engines are more fuel efficient than gasoline engines and produce fewer emissions, there is very little incentive for car and pickup truck manufacturers to produce them. Diesel engines are more expensive to produce than gasoline engines.
