multiple turbo diesel madness

hmm...seems we could go for a while, we both drive diesels anyway....

does he love diesels too? -In the UK the government are evil, they know people buy diesels now so charge more for diesel! you need to drive 1000s of miles in a diesel car to make up the difference after shelling out for a pricier car and fuel

you might want to read some of his posts in this thread

[jediali]

just been reading Ferrers posts. He has a good argument and so do you(henk4). Its very subjective. I would take a 535d over a 540i but not a C1 hdi over a C1 1.0.

I'd agree with you if it weren't for the fact that you were wrong.

As of 1st September 2006:

Sulphur-free petrol/diesel 48.35p
Ultra low sulphur petrol/diesel 48.35p

Don't forget that diesel and petrol don't start off costing the same anyway.

im confused, petrol is 85p/litre, diesel 94p/litre where i am right now.

85 - 48.35 = 36.65p before duty

94 - 48.35 = 45.65p before duty

Those prices are the fuel duty per litre - the amount the government charges.

It is the same for both petrol and diesel.

Diesel cars are only a little more expensive to buy (roughly 2%) but fuel is 20-25% cheaper! here in denmark

Personally I love diesel cars because they are almost always much stronger than comparable petrol cars until 5000rpm.

For example a comparison between a 2005 BMW 335d and the 2007 335i shows that:
-----------Diesel HP / Petrol HP
@ 1800rpm 125 hp / 75 hp
@ 2600rpm 180 hp / 140 hp
@ 3400rpm 220 hp / 195 hp
@ 4200rpm 230 hp / 225 hp

Note that the diesel is not only being compared to a petrol of the same size (normally diesels are larger) but that the petrol it is being compared to has a twin turbo system designed to maximise low down HP. Note also that the peak HP of the diesel is only 235hp and the petrol maxes out at 302hp.

So that is one of the reasons I like diesels... You can stomp others at the stop light without sounding like a drag car and attracting cops.

so government puts more duty on diesels then...

hightower, you are a tower of knowledge.

good argument but the 335i is a low pressure system, the 535d has a high boost a boost similar to that given the duratec 3.0 v6 put in the noble m15 and that produces 425hp

BUT we are comparing apples and oranges. I love some cars and im not going to change my mind just cos it costs x pence lower to fuel or because i can drive it at idle.

OK well about that:

The low pressure system used on the 335i is designed to max out low down HP. It has no lag at all (it makes 2 psi boost at idle) so the turbo improves the petrol engines performance from idle. Now the high pressure system you talked about doesn't even come in until 3300-3500rpm and therefor actually decreases the performance of the engine below that point meaning it would make the diesel look even better.


Diesels are great and I personally would take a good one over a luke warm petrol...

and by the way the diesel I qwas talking about is the 335d not the 535d not that it makes much difference

also the nobel M15 makes 455hp and has a max boost pressure of around 20psi whereas the 335i only uses 12psi

There's one thing I'd like to point out. In my opinion it's wrong making general claims. It all depends on which diesel and petrol engines are we talking about. The 286bhp 3-litre twin turbo diesel BMW straight six might be great but I doubt you can tell me the same about the 75bhp 2-litre normally aspirated diesel mounted in the Golf. And the same can be said comparing the 170bhp 1.4-litre twincharged inline four from Volkswagen and the 54bhp 1.1-litre normally aspirated inline four from Fiat.

My general claim is that diesels are stronger than petrols up to 4-5000rpm

and they are you will be hard pressed to find a situation where the comparable diesel is weaker than the pertrol at low rpm

[Coventrysucks]

so government puts more duty on diesels then...

This is the amount of fuel duty applied by the government, as of the 1st September 2006:

Sulphur-free petrol/diesel 48.35p
Ultra low sulphur petrol/diesel 48.35p

Check the link that I posted - oddly enough I didn't include it for my own amusement.
