Do you think also that someone spending a huge amount of money on an R8 will worry about saving a few bucks per year?

I think, like the Veyron, it's a test to see what they can do. It's a supercar with monster torque, I doubt anyone cares about the fuel economy or whether it's a low carbon alternative to the petrol version. You say why build it, I say why not?

I expect the R8 Tdi is a success, even if they sell just one

How many Audis do they sell on the back of the R8? with ties in from the boggo range

now how many people are talking about Audi Diesels because of the R8D ?

the problem is when people compare diesels to petrols they are usually comparing tdi to petrol n/a

a good 2.0 tdi would get spanked by its equivalent 2.0 petrol turbo.

Actualy thats nonsense. I have the new B6 sport pack passat, 170bhp diesel, and 394nm torque. I test drove the 2.0t fsi as well. The TDi blew my mind, and it is far far quicker. I should imagine the same would apply to the GTi golf and 170bhp Golf GT diesel. Just because you dont rev the nuts of a diesel does not make it slow. Torque is where your accelration comes from. Where else can you get a car that does 0-60 is a fraction over six seconds, and still returns 46-54 mpg?

I am a petrol head, as such I appreciate the engineering required to build the machines we love. Why be so narrow minded when it comes to diesel. I think both have merrits, and I embrace both technologies equaly.

Yep publiicty. No doubt this powerhouse will end up available in a Q7 or A8.

when it comes to everyday cars, that is 1.0 - 1.4 8v petrol and 1.7D- 1.9D, I still will choose a diesel because ok, it will not give you the feel a 16v polo will but it's so much more comfortable to drive, with less gear changes and less struggles at low revs.

I used my gfs 1.3 petrol for a weekend and I noticed this immediately, at low rpm there is no way you'll feel any sign of power at all, and climbing up a hill is a pain in the a** .

I'm feeling acute asthma just imagining the soot that churns out.

Diesel particulate filters mean you could breathe the fumes in all day long and not get ill or covered in soot!

Well that's shit because all diesels chuck out black soot when you accelerate hard.

One of the main rules allowing TDI's into motor sport was that they would emit no soot/harmful fumes, watch le man, and touring cars, try and find the soot, and now all H.G.Vs entering london must have a particulate filter aswell as cabs,

taken from wikipedia, A diesel particulate filter, sometimes called a DPF, is a device designed to remove diesel particulate matter or soot from the exhaust gas of a diesel engine. Wall-flow diesel particulate filters usually remove 85% or more of the soot, and can at times (heavily loaded condition) attain soot removal efficiencies of close to 100%. A diesel-powered vehicle equipped with functioning filter will emit no visible smoke from its exhaust pipe.

Well it appears they only manage efficiencies close to 100% some of the time...so there is still going to be soot?

I am sure there is still lots of nasty shit pumping out diesel exhaust pipes.

DPFs have only been introduced very reecently, for Euro IV emissions standards I think. So It's only diesel cars made in the last 3 years or so that have them.

I drive a PD 130 Seat Cordoba to and from work everyday. Clock up about 250 miles a week. I get about 50mpg at the moment. (enjoying the performance :)) A petrol with similar performance would be lucky to get 40mpg from the same commute. So i'm definately better off with a diesel, It was more expensive to buy, but it will also hold its value better than the petrol eqivalent so you get some of that extra cash back come for sale time. The skoda I had before this. I had for 2 years and it only depreciated £500 in that time. Which is not much at all. Plus it's only £120 a year to tax. A petrol with the same performance would cost double.

I was going to post a big ranty reply to this t'other day - but I think Alex/Jez have pretty much covered what I was going to say!

Whilst I don't get to drive as many different vehicles as a motoring hack like Alex, I still get to drive a large variety - development vehicles/prototypes, hire cars or other cars we've got in for benchmarking. I'm not a diesel fan really, and I don't think they're quite developed enough to make a truely entertaining sports car, but they do very much have their place. Having said that, I've not driven anything with such sporting pretensions as the R8 TDI, and the JCB Dieselmax thing seemed to go okay...

Yep publiicty. No doubt this powerhouse will end up available in a Q7 or A8.

Tada !

my van has a particulate filter... oh wait no it hasn't well not anymore

sounds like a group B audi quatro on steroids now

T4's didnt have particulate filters just a cat the newer T5's and Crafters now have particulate filters.

the diesel vs petrol argument is about as pointless as the other internet battles such as imports vs domestic, turbo vs supercharger, injection vs carb. at the end of the day your not going to get some people to agree with whichever side because some people are just too narrow minded. this thread has turned into a waste of time if you ask me.
