Diiference in Petrol & diesel vehicle prices.....

Why diesel car prices are more than petrol cars? Can anyone explain?

Simple diesel is cheap than petrol.

Ya.....that's true.......but any technical reason.......?

If diesel cars become equal or cheap than  petrol cars, most of them would prefer diesel cars. And this in turn will increase diesel prices. Because there would be more demand for diesel than petrol.

Diesel cars are no more roaring machines they have become smooth and silent day by day, and also you can expect more mileage than petrol cars.

There are more advantages in choosing diesel car than petrol car. So due to these advantages manufactures and taking premium for that.

Hope that makes sense.

Technically speaking I dont have deep knowledge inside the machine.

However I am not sure how much relevent this information for this thread. But it is definitely worth reading.

A diesel engine is costlier to manufacture than a petrol engine of the same capacity.

Due to the way a diesel engine works, the engine has to be physically stronger and rugged to take the power generated during the "ignition" stroke - ignition in quotes because diesels work by compression detonation of the fuel rather than burning. This is a result of far more compression of the diesel-air mix than petrol-air mix and thus the extracted power is more from diesel. In addition to more power extracted from the power-stroke, the resulting physical forces are also greater, so the cylinder walls, piston etc have to be heavier/thicker to take that force. In all this means that a diesel engine of the same capacity as a petrol engine will be heavier - and naturally contains more metal which directly increases its cost.

Add to that the fact that a diesel engine may also have turbo-charging and/or intercooling which further increase the engine's cost.

Thus, in the same car the diesel engine will cause the overall price to be greater than the petrol version.

Thank you very much guys for your inputs.......!!!!!

diesel engine has got more power than petrol engine and thats the reason for differenc in price.

Diesel is thick and more in density

Hi, Got to know your perfectly asked query. Because a DIESEL engine is efficient only then when its size is big(In term of cc), it will generate more power relatvely to petrol engine. Since this engine is not having any carborator, spark plug which is used in petrol engine. The design of diesel engine is so sophesticated that it catchs fire in combustion chamber due to applied a heavy pressure.

We all know that DIESEL is having much more impurities as compared to PETROL, the removal of wastage is also a big task

In such countries wher diesel price is not cross subsidised by petrol price,the selling price of diesel and petrol variants is not much different. Even in India when Skoda was new entrant,they were pricing diesel and petrol  versions very close to each other.Slowly they also have learnt the trick that as diesel is priced lower than petrol,car cos can charge a premium on diesel version and the premium is so cleverly worked out that the buyer ie us do not end up with any advantage in long run.
