Diesel doom

[RetroPug]

Didn't they rule a few years ago though that you can't belatedly change car tax? So if your car was registered in 2006 and it is £30 a year then it will always be £30, but if the same car with the same engine and same emissions registered after they raise the tax that's fine...

It would at least give it 5-10 years for us all to slowly filter back onto petrols. My question is what will they do on the continent where because diesel is cheaper than petrol diesel is the undisputed king ?

Diesel is cheaper to refine. The government is already imposing extra tax on dervs by taxing diesel fuel more, thus making it more expensive.
This is under the guise of making up for emissions but in reality the government realised that they would be out of pocket if people were using less litres AND paying less tax per litre.

Diesel is great for a daily car, it is just a bit more dirty, however you are using less fuel which is a benefit.

For countries with huge, long open roads like German autobahns diesel will continue to be more suitable than petrol for quite some time in terms of efficiency. Whether or not they'll be forced off the road remains to be seen. In reality, I think it'll be like the 1990s when everyone was raving about diesels: petrols didn't just disappear. Both will continue to get better.

What is interesting is that some diesel technologies may begin to transfer. Compression ignition petrol engines may enter mass poduction, for example.
