New generation diesel

[kiato4]

I'll take the Touareg's 5.0L V10 TDI... that baby rocks.

i drove yesterday the "new" 530d BMW! I think that this car has the best diesel engine in the world! It's VERY powerful, and you dont have to visit the Gas Station every 200km.. I JUST LOVE IT!!

[Overmind]

well diesel fuel is not only cheaper here in Europe, but a diesel engine usually does more miles per gallon. Diesel cars are usualy more expensive, so you have to drive a lot in order to spare money.

#1-> Brabus V8 4L CDI
#2-> VW V-10 5L TDI
#3-> Duramax V8 6.6L (Dodge/Isuzu)
#4-> Detroit Diesels V8 7.8L
#5-> AMG inline5 3L CDI

if i were to mod and tune 1 up, the best value would be the Duramax that can go a woopin 450hp and 1000Nm b4 propane done by any1 that know how to use tools and a little brain power...

You have a wider torque range to play with, en sounds so much better And if you compare diesel and petrols the right way (normal aspirated vs normal aspirated and turbocharged vs turbocharged), petrols will always outperform their diesel friends. Except sometimes diesel will be a little bit quicker in very short sprints from 70 to 80 km/u for example. But when viewing the whole picture, petrols just have better performance figures.

Petrol has more kw(top speed), diesel has more Nm(acceleration), a 2L turbo petrol = a 2.2L turbo diesel = a 3.4L n/a petrol = a 1.3L n/a rotary petrol = a 1.6L n/a rotary diesel (FIA) :arrow: but in this case, since these engines all produce the same Kw, any diesel will be averaging a +10~15% in Nm. So I'd take the diesel and start runing biodiesel. That would be a 10% more acceleration for 4% total biodegradable pollution!!

If you compare a 2.0 turbo petrol with a 2.0 turbodiesel, and put in exact the same car, the petrol will outperform the diesel.
The diesel may have a little bit more torque (it depends which engines you're comparing) but due to the smaller rev-range longer accelerations will be less fast.
When accelerating form a certain speed, the diesel with more torque will be quicker in the beginning, but will run out of revs (torque drops really fast at high revs due to the engine speedlimiter on diesel engines), where as the petrol will continue accelerating. Eventually you will also ran out of revs with the petrol.
This limited usefull rev-range limits longer accelerating runs. Also a diesel will have longer gear ratio's (due to the low rev characteristic), which is not helpfull for fast accelerating times.
