Tom's TDCi Titanium X...

[Toms306]

These are a good steer, my boss just P/x'd a 2007 (earlier pre-facelift) 2.0 TDCi and it was a stonking chassis with plenty of oomph.

We've driven loads of rentals with the 1.6 diesel engine in and they go alright, never going to set the world on fire but they serve a purpose and do 45+ mpg all day long. Our results are somewhat hampered mind, since they are 'rentals' after all

It wouldn't be my choice, but I can see how it appeals. I prefer to think a bigger, less-stressed engine will get equivalent / better mpg with the extra power there if you want it, especially the way I drive. You can find the performance limit of these 1.6 diesels very quickly. How would it go with a remap?! :p

Same boss recently picked up a 1.7 Zafira because it said it would do 65mpg. HA! It does 43. And is slow as fook. Should have got the 1.9 all along like I insisted!

Christ, I get better than 45mpg in town! But I see your point about them being rentals.

Its obviously not a performance motor, but I don't find it runs of puff with me tbh, and it doesn't feel 'stressed' either, not like a 1.4 306 or a 106 NAD does, I find 306 HDis feel stressed as well really, but that's more to do with the gearbox I think, they need a 6th imo.

Were your 1.6s, 110s or 90s? I was quite surprised the difference that that 20bhp (and the extra torque) made tbh! I tested a 1.6 90 'studio' (less spec than a Rallye! ) at the main dealer up for the same price as mine was, really didn't feel like enough power for the weight imo. The 110 will happily sit at 90 if you don't mind burning fuel lol, but obviously the 2.0 would get you to 90 faster. But then even that's only another 25bhp...not worth the extra fuel, tax and insurance for me so the best compromise between the 1.6 90 and the 2.0 136 was the 1.6 110.

Not sure what they do with a remap, I'd imagine better performance and economy than the 2.0, but I'm not gonna push my luck like that this time, I don't drive it wishing it had more power so until that happens I probably wont bother lol. I don't reckon the turbo would be efficient with much more power though, its pretty small, GT1544v I think, but I'm sure JP or Ruan will know what they're capable of if I do decide to go for a remap. Wont be anytime soon though, £250 insurance the year is nice!

With the Vauxhall engines, I don't think they make an efficient diesel. They get decent power from them, but at the expense of economy it seems. I never managed 50mpg with the 150CDTi in the Vectra, probably get even less in the heavier Zafira.
