i have found that diesel cars can be really nice to drive, the only passenger car i have driven is the mazda 6, which i have found to be a really nice to drive. yes they do run out higher up in the rev range but they are really good on fuel so why worry!

if you are buying a car to be cheap on fuel why are you trying to thrash it anyway??

[QUOTE=WhiteRX]I havent driven one yet, though im sure it is proberly as quick as a NA petrol engine of the same size, though proberly down on torque. driven plenty of bmw and vw diesel's though and they all have a torque band of like 2500rpm max, how boring. But still, if it is the type of car that you like then go out and enjoy it.[/QUOTE]

Yeah 450nm of torque at 1400rpm is pretty boring :)

Don"t Worry Joe! He Knows What He Is Talking About !!!!!!!!!11111

also, how many have been in a "modded" diesel?

double the boost, change the zaust...add fuel! Add lots of timing...

Yes, well to me :D my engine never sees the under side of 3200rpm, except when idling. Howmuch torque does it have at 7500 rpm? If it had that much then it would be making serious power... or is that when it goes bang, from such a long stroke and such heavy (but robust) engine componets.

Anyway as Tim said, they are great for just driving around slowly, give great fuel consumption if driven sedately. Diesel engines have loads of torque low down, but because of the long stroke required to get such high combustion pressures, their ability to revv is far less, due to being so far over square. The piston speed is too high.
They are also great, when designed to operate at a fixed speed, like generators.

Me personally, i love the feeling and sound of a engine going up to and past 7000 rpm :D

Why are revs so important to you? Just because an engine makes all its power between 1000 and 4000rpm, does that make it shit?

Most diesel's have extra gear ratios to keep the engine in its power band. 6 speed's are the norm, auto and manual.

You dont have to rev them to go quick, and most diesels will be just as quick as their petrol counterparts, but with a LOT more torque, which makes them more driveable around town and a lot more enjoyable to drive. You get a real push in the back sensation, more than with a petrol engine.

Over square, heavy engine components and long stroke? Thats making some huge generalisations. Many diesels have forged pistons and alloy heads, just like good petrol performance engines.

You can drive a diesel around VERY quickly, with very little rpm. They don't have to be driven slow.

In fact, in my uncles Audi A6 diesel, I drove it around and averaged across two tanks, just under 10 litres per 100km. That included 75% city driving, and the rest freeway driving. It even included a Fri nite cruise that involved a LOT of heavy acceleration. Yes, gearchanges were at 4500rpm, but it hauled arse below that!!!

I'm not arguing about this any further, but let me just say, you best be test driving some modern euro diesels...you might be pleasantly surprised.

I do understand where you are coming from, and im not saying that they are shit. What i am saying is application. If your happy with a diesel then thats cool.
I have driven quite a few euro cars, well hundreds, as i work for a workshop that specialises in euro's, and know that i dont really like the feeling diesels have. Just me though.

Over square, heavy engine components and long stroke are all requirments of a diesel engine. They need the stroke length/bore stroke ratio to ignite the air/fuel mix, otherwise they would need spark plugs. The air being compresses generates the heat to initiate combustion.
The engine needs to have heavy components to resist the constant detination, otherwise the engine wouldnt last very long at all. And they need a heavy flywheel to keep them going at idle, due to so much combustion pressure.

all alloy engines is where it's at. Japs have used them since the 70's

I like reving my engine. I personally love the feeling, the sound, and knowing whats going on inside. I really admire some of the engines that honda, mazda and mitsubishi make, many are understated and feel fantastic at 7000+rpm
Petrol engines use the gearbox to make the torque, that makes the car just as quick.
Not to mention that a petrol engine and diesel of the same size and design, the petrol will always be faster(99% of the time) . Not more fuel efficient, but faster.

Anyway, not trying to be rude or anything, just a bit of fun :)

Audi diesel? VW diesel? BMW diesel?.....pfftt :rolleyes:
