Diesel vs Petrol

I would also suggest comparing a turbo-petrol to a turbo-diesel, for example a BMW 320d vs Audi A4 2.0T
:thumb:

Did that... The BMW Diesel still feels better IMO.

i have yet to be beaten by a diesel :) many have tried... but i guess not hard enough...

:slap: Your car isnt standard... :mmm:

Bring ur 330i and come :p....

M_Diesel,

I left the same challenge out there to a prefacelift standard 330i a while back... and thats to take on my Lci 320d... :mmm: Had no takers yet. Seems like the 'petrol guys' are scared to put their money where their mouths are...

Runs quickly and sits in the 'diesel corner' :)

I still say bring your N/A 3.0l diesel up against my 3.0l N/A petrol, then there is something to see.

There really is no point comparing the performance of an N/A car to that of a F/I car, because it is two different things.

Like I said before between turbo-diesel and petrol engined cars, each has its own merits, and you have to choose based on that. I for one don't like the sound of diesel car, the smell, the smoke, and the fact that its F/I so I went for a petrol engined car.

You cannot compare turbo diesel to turbo petrol or na diesel to na petrol, it is different technologies. The way the diesel operates, makes it much more suitable for turboing than petrol (you can basically boost as much as you like). Petrol is much more limited in terms of boost capacity. Diesel is also much more efficient, especially when turboed, where petrol becomes less efficient much quicker. Diesel also has the advantage of being much more compatible with VNT turbos, meaning that you can pretty much eliminate lag while still boosting 1.5bar+ above atmospheric. Each type has there place, but 99% of the time in normal domestic applications, turbo diesel trumps petrol, largely due to the enormous fuel savings, while sacrificing no power. I would consider a NA petrol if I lived at the coast, but up here you just lose so much power.

i did not say that diesels are slow... just that i have not been beaten by one :) it does seem there are alot of over confident diesel drivers out there (mostly VW)... guess its the low down torque or some sort of inferiority complex :)

all jokes aside im very impressed at how well diesels tuneup... would i buy one... no im very happy with my car

im running a 3.38 ratio and the car seems about even with a 330i... im not very interested in drag racing... but using a few calculators it seems my car should get between 15-16

you do realize i live in pmb?

My Brother Just bought the brand new 535d 8 speed auto in some metallic royal blue colour. R790000 (Crazy Fcu8ker)

OMG - That thing is RAPID!!!!!!!! He upgraded from an Audi A6 3.0TDi which was damn quick.

Apparently this 535d has a turbo and a super charger. There is NO lag what so ever. I honestly never thought a diesel could pull like this thing and with the eight gears it never seems to run out of steam like a normal diesel does with the redline coming up so fast. To top it off he is running at around 8.5/ 9 lt /100km and he does not drive miss daisy.

I personally love an engine that Revs and have always said I would never drive a diesel but damn, i would chose this thing over a petrol engine any day of the week.

It has two turbos. There is no stock BMW that sports a supercharger. That and the fact that superchargers efficiencies become stupidly low at the pressure ratios needed to boost a diesel properly. The fact that there is no lag is due the twin sequential VNT turbo configuration married with some clever control systems engineering...

Hmmmm.....Interesting!

Two different size turbos I guess to boost through all rev ranges?

Only downside is that he has probably lost about R200k on it since he has put 1600kms on it already :dunno:

Yes that is it. Also because it boosts in the region of 2 bar above atmospheric.

LOL, that is sad but true.

One doesnt buy a BMW thinking about the resale value.

Its a very well known fact that just driving it out the showroom greatly devalues the car, so the only thing thing remaining (the most important), is the unrivalled quality and driving experience.

Buying a BMW is a very emotional thing. Sometimes it can make you angry, but for the most part you will smile everytime you even think about the car.


This Diesel vs Petrol debate is as old as the Pakistan / India - Kashmir battle.

Both have unique characteristics, including pros and cons, that appeal to different people and their driving styles. It shouldnt matter which engine you choose. What Should matter is the fact that you chose a BMW in the first place.


Lets quit this pointless battle and enjoy the best cars in the world.



P.s. If I had a choice, I'd take the 535D as well. just such an awesome car. And if I wanted a 3 Series it would have to be the 335D. Just my opinion, as im sure that others here would prefer the petrol deriveratives.

323i vs 330i with only change made to the ratio "even" with a 330i" neva....
And the altitude would neva get your car in front with a 530d coz it's making 170kw 480 nm std so chipped gets you to around 200kw vs your 128kw do the cals... doing 15 in your dreams.. or maybe on your own hand held stopwatch...

Kinnear i dont give a rats ass how fast my car is in a strait line... thats why i have never done a timed run with it... there are a few other mods im pushing about 150kw... but the 3.38 made the most difference by far... most diesels run very long ratios...

i did not say my car was fast... but it seems every diesel owner thinks he has a rocket... from what i have experienced it just has not been the case... not that im any sort of expert

why does everything with you have to turn into a pissing contest? do you suffer from a small penis size or something...

I have been reading this whole thread, front to back. Petrol vs. Diesel is soo old guys. The thread originator wants pros and cons, he has to make a very expensive and long lasting descision.

Personally for me owning a diesel has and is a great experience. Great Fuel consumption, minimum maintenance and oozles of torque. Driving style does take getting used to IMHO.

In about a year I will be looking for another vehicle, specifically 325i, 330i or 330D. What is gonna matter at that stage is fuel prices and general overall condition of cars available, whatever variant.

Yes i do:banghead:Wonder why??? coz its :bawling: to think that my little fella(brainpenis) is small yet has more brain size then your Nut Shell upstairs....Understand!!.If a Grandpa with his 330i+ his Venter Trailer cruise to his vacastion at 160km:pimp: and you passes him its doesn't mean you keep up with him use that nut shell man coz a 330i has 173kw how would yo keep up with a short gear ratio.. Keeping up does not meen that you raced him in first gear while he was looking the other way and when he wnted to past you, you heat the Beaks and tell your girlfriend a beat that Grandpa...:hammerhead:
