Should I buy a diesel car in 2020?
Yes, of course you should still buy diesel cars (if you don’t give a toss about urban air quality, people with respiratory problems or children’s long-term health).
Even if the latest technologies are cleaner, they are not clean enough, particularly if not well-maintained and run mainly on short, cold local journeys..
How clean is a modern diesel engine?
“Modern diesels essentially do not have a particulates problem,” he says. “The filters clean up 99% of the particles. So long as they are not tampered with, they are very effective”. But diesels also produce nitrogen oxides, or NOx – and how they deal with those is also very important.
Why diesel engine has more efficiency?
A diesel engine uses a much higher compression ratio within the cylinder to heat the air inside. … Because the air is so compressed, the engine gets greater efficiency from the fuel. This means a diesel engine is generally 20 per cent more efficient than an equivalent petrol engine.
Which car is best diesel?

What is the disadvantage of diesel cars?
Cons of Diesel Engines Diesel vehicles are more expensive. Some buyers may feel the fuel-efficiency and durability are not worth the extra cost. Engines are more technologically advanced, so service may cost more if you neglect proper maintenance. Diesel fuel is more expensive and can sometimes be harder to find.
Is 1.6 or 2.0 engine better?
Yeah, the displacement for the 2.0 L is 25% larger than for the 1.6 L engine. … Generally, with non-turbo engines, the 2.0 litre will have more low down punch (torque) and be a more relaxed performer.
Why are diesel engines bad?
While diesel engines are meant to be more efficient than petrol engines, diesel cars have received a tremendous amount of bad press. They are said to release toxic gases such as noxious pollutants which are linked to premature deaths. With over half our cars in Europe being Diesel this is extremely alarming.
What is the most efficient diesel engine?
Finnish technology group Wärtsilä has introduced a gas-fueled version of its Wärtsilä 31 marine engine, which is recognized by Guinness World Records as the world’s most efficient 4-stroke diesel engine.
How efficient are modern engines?
Modern gasoline engines have a maximum thermal efficiency of more than 50%, but road legal cars are only about 20% to 35% when used to power a car. … At high speeds, efficiency in both types of engine is reduced by pumping and mechanical frictional losses, and the shorter period within which combustion has to take place.
What is the most efficient engine ever?
The new Wärtsilä 31 is the most fuel-efficient four-stroke engine currently available on the market.
Which engine is the most efficient?
TOKYO — Mazda Motor has developed what it claims is the world’s most fuel-efficient gasoline-powered engine, the carmaker said Tuesday. Called the Skyactiv-X, the engine is the first gasoline model that ignites the fuel-air mixture through compression, like a diesel engine.
Will diesel be banned?
The government has announced that the sale of new petrol and diesel cars will be banned by 2040, along with most hybrid cars that use existing technology. … Even if your petrol or diesel car is still running in 2040, there are no plans to ban it from the roads entirely, as second-hand sales are expected to be unaffected.
