Diesel v Petrol

Following on from previous threads I see the VAG Diesel Engined cars have again wiped the floor with the Victoriana petrol engine Porsches, Lolas, Ferraris etc. at Le Mans. It’s the future! A 200bhp diesel in the EOS would be nice.

I went into manchester vw and was looking at new cars not for me for my OH's dad, I said to the sales guy i have the 2.0 tdi sport and he said it was the best model so its better than petrol ner ner!!

Steph xx :p
lol the future is not on diesel thankfully.
That race is just a marketing move to fool you guys, they won just because they had better gas milage and didn't pit stop.
There was a report mentioned in the motoring press last week (emanating from used car guide Glass's) which stated that "The average diesel car requires 7 years to pay for itself in reduced fuel bills" such is the extra expense of buying the car and the fuel!



Diesel fuel used to cost less than gasoline/petrol in the US during the 70's when I had a Mercedes 240D. Since that time the price has matched gas and presently is about 10% more. As neh321 points out, there is a long time before the break even point. However, if your bladder will hold it, you can GO a long time between pit stops!
They won because they were faster for longer. Still even in the world of diesels VAG gave PSA a good kicking. Weird thing is the diesels are incredibly quiet - almost dull -but they are incredibly fast too. I think you will find they did pit stop but it was the usual French shambles that helped the slower Audi cars, that and the rain on Sunday. Anyway it was worth seeing just to listen to a well beaten Jacques Villeneuve whining afterwards. Next year they will change the rules to suit slower petrol engine cars.

On an EOS note I managed 28.8mpg on the way home tonight - a personal best. The bit about diesels taking longer to pay back is a sweeping generalisation. It depends entirely on personal circumstances and varies massively depending on your situation. The cost of any car depends on personal circumstances and purchase method. I’m sure that for private buyers who don’t do many miles - up to 12k used to be the rule of thumb I think - the petrol is probably cheaper to buy. Then it depends on insurance - the TDi is a lot cheaper, but again depending on personal circumstances. My cars a lease car through work and the TDi is a lot cheaper than the petrol, fuel gets subsidised and there aren’t any tax implications so with 25K plus miles a year the TDi wins by a long way. At the of 3 years its GRV is just over £10K. The petrol model is slightly less. However, if I bought my own car, if I only used it on a Sunday I’m sure I'd get the petrol engine.

I think the TDi is underpowered but its pick up from 30 - 50 is ok. With DSG and paddle shift its pretty good fun but much past 70 it’s starting to show the 60bhp difference. Nice car though. I just need to find that missing bhp - since its that that makes a car faster and quicker! Audi R10 anyone?

In Oz the TDI is AUD2k cheaper than the TFSI. The 40-50% fuel efficiency advantage with the TDI negates the slightly 12-15% cheaper petrol here in Oz.
End of arguement.

Yes, of course the report referred to the UK and did say the average car... There will always be those at opposite ends of the scale and some high-milers will get the advantage quickly whilst some low-milers will never get it!

With different pricing of both the cars and fuel in different markets circumstances will not be the same everywhere.

I presume that's a WORST? My TDI managed 60.0 mpg over the 89 miles I drove to work yesterday :D . Currenly the MFD shows 50.1 mpg as an average over 2600 miles.

I drive up to 33K miles per year, there really was no choice. The extra economy over my previous car (A Mazda 6 diesel) has offset the fuel rise over the past 12 months.
Yes - best at getting low figures - I was surprised at 28.8mpg. twisty windy road, in tiptronic mode and using the paddleshift. great fun. If I pootle in another way I ususally get about 55mpg. I'm in the same boat - this car is cheaper even with the fuel hike than my previous car.
... the report referred to the UK ...

I'm in the UK too ... the diesel was cheaper to buy and has a higher GRV within our scheme.
i think the public has been dupped into buying diesel and it shoud have been kept in tractors
manufaturers have gone along and wasted millions on it and now need to get their money back. when they try harder they can produce better fuel efficient decent petrol engines like vw's own tfsi or mercs new Gasoline Compression Ignition system. 1.8t, 238 bhp, 400nm torque, 127g co2 and 44mpg!
i know diesel can be cheaper if you do 20k plus a year but i worked out i would only save £150 on juice, a small price to pay to avoid having to drive around in a niosy, vibrating, dirty, smelling, underperforming, unrefined car. plus the mess you can get every time you fill up and diesel links to cancer

BAN DIESEL :mad:
Petrol is VERY carcinogenic.

The Material Safety Data Sheet for unleaded gasoline shows at least fifteen hazardous chemicals occurring in various amounts. These include benzene (up to 5% by volume), toluene (up to 35% by volume), naphthalene (up to 1% by volume), trimethylbenzene (up to 7% by volume), MTBE (up to 18% by volume) and about 10 others.

BAN PETROL.
True, but I tend to burn mine not use externally or internally.
The biggest potential carcinogen problem for the future will be the hydrocarbo nano partical emissions from diesel engines. The more diesels there are the bigger the problems for the future.
What we need are polution free engines using fuel cells or simple hydrogen to replace all current engines.
Well who'd have thought the wifes car would cause so many insecurities to surface. A few days away and all this to come back to.
