Is it better to buy a diesel or petrol car?

Diesels deliver more power at lower engine revs than their petrol equivalent. This makes diesels feel more suited to longer motorway trips because they’re not working as hard as petrol engines to produce the same performance. This also helps to make diesel cars better suited for towing.

Are diesel cars better?

Diesel engines are still more efficient than gas engines, but less so for those who are mostly engaged in city driving. Diesel cars also have more torque, which results in better fuel economy along with more impressive acceleration. For most U.S. consumers, diesel fuel and gas fuel cost about the same.

What’s the difference between petrol and diesel?

Both petrol and diesel engines are internal combustion engines. The difference between petrol and diesel is found in the way that the combustion occurs. Whilst a petrol engine combines fuel with air before being ignited by spark plugs, in a diesel engine the air is compressed beforehand and then the fuel is injected.

Is petrol or diesel better for the environment?

Diesel engines are “lean-burn”, meaning they use less fuel and more air to get the same performance as a petrol engine. So, while diesel fuel contains slightly more carbon (2.68kg CO₂/litre) than petrol (2.31kg CO₂/litre), overall CO₂ emissions of a diesel car tend to be lower.

Is diesel worse than petrol?

So, while diesel fuel contains slightly more carbon (2.68kg CO₂/litre) than petrol (2.31kg CO₂/litre), overall CO₂ emissions of a diesel car tend to be lower. In use, on average, this equates to around 200g CO₂/km for petrol and 120g CO₂/km for diesel.

What is the benefit of a diesel car?

Diesels get great mileage. They typically deliver 25 to 30 percent better fuel economy than similarly performing gasoline engines. Diesel fuel is one of the most efficient and energy dense fuels available today. Because it contains more usable energy than gasoline, it delivers better fuel economy.
