I am one of those Ex-petrol Converts. I remember when my company were going to force us all to drive diesel company cars a couple of years ago - people were actually going to resign if they did [:O]
Having said that the new generations of diesel are soooooo much better. I did find that the 2.0Tdi I have was a litlle noisier than I had expected, and is certainly louder than my wifes Mondeo(cough,cough) 2.o Tdci GhiaX, but then that may have something to do with sound deadening materials?
Anyway, you should drive both and then make up your own mind (i am sure you would anyway), but don't fall into the trap of thinking the diesel is more expensive to buy than a petrol. Yes, you will pay more for it initially, but as well as the MGP savings, which are only really relevant to high mileage driver, you will also realise a much better residual value in the current 2nd hand market. This may change though if they carry on stinging diesel drivers at the pumps at the rate at which they are. I saw diesel for 10pence more than petrol yesterday - was'nt so long ago that it was more than 10 pence cheaper.
Lastly, on yoour test drive don'nt make the mistake of revving the nuts out of the diesel, use it's torque and gears to gain the best speed.
My experience two weeks ago was that I had placed a deposit on a 6 month old 2.0 GT FSI. I then heard about the mpg figures obtained by others on this forum (generally between 26 and 31) and that made me decide I should be buying the diesel instead. I then found a 2.0 GT TDI for the same money but 11 months old. I collected it 10 days ago and have been really pleased with it. First fill up was yesterday after covering 500 miles. Performance is superb too and despite being a diesel the car is no slouch once its moving and acceleration for overtaking is excellent and effortless (no need to thrash it).
Looking at the specs the FSI is slightly faster by a few fractions of a second i think, HOWEVER the TDI is ALOT faster when driving imo. You got loads of power from like 2k, doesnt matter what gear your in.
To get some decent speed outa the FSI you gotta rev it all the way up to the top of the rev band before changing.
Ok guys, I've been in to the dealers today and done back to beck tests on the 2.0 FSI, imediately followed by the 2.0 TDI. The TDI was much better to drive than the FSI. It feels like a much faster car. Lots of low down torque and really useable power. Much more fun. The FSI was quieter, but it felt like you had to wind it up a bit more that the TDI. I actually prefered the growlyness of the TDI too. So, all in all, the TDI is much more fun, and more efficient although a bit more expensive. The TDI I drove had only done 5 miles, and the FSI had done 7000!
VW Driver did test the GT FSI in Feb 2005; these were the figs:
Golf 5 2.0 FSi
Max Speed - 128
0-60 - 8.5
0-80 - 14.6
30-50 (in 3rd) 4.8
50-70 (in 4th) 6.6
50-70 (in 5th) 8.6
The 0-60 time is actually slower than 2.0TDI; interestingly the mid-range times for the 2.0FSI seems very similar to 1.8T(150). This is no doubt helped by having a 6 speed g/box.
Diesels always seem to be quicker for comparable mid-range times but imo a petrol engined car can always be driven in a lower gear due to it being much quieter than the average diesel car. I had a test drive in a MKV 2.0TDI prior to buying another MKIV 1.8T and was very disappointed by the refinement; maybe it was a poor example but it seemed noisier than other 130/150TDIs that I've driven.
"Me female dog" was a passenger on both drives in the FSI and TDI and she said the TDI felt much faster. When I put my foot down in the FSI she didnt flinch or look at all concerned, but in the TDI I could feel her tence a little and she looked across at me (always a good sign).
