Cold GTD vs Cold GTI Real MPG, Short Commute.

[corgi]

A lot will depend on your driving style and if you have heating/stereo up high, windows down, temp outside etc.

Heating, stereo, lights, heated rear window etc will make no measurable difference to fuel consumption. Window down will at speed and outside temperature only makes a difference to warm-up once up to temperature low ambient should help but warm-up on DI Diesels can take a long time...

Cold start 14 mile trip to work yesterday returned me 40.2 mpg in my GTI.
14 miles is probably not a short trip though and I was in slow moving traffic 40/50 mph.

Here's a question to the OP.... the difference between 30mpg and 40mpg on a 30 miles per week commute equates to what?

Every 4 weeks you would save one gallon of fuel... £6 per month? I know £6 is £6 and if you haven't got it then its £6 too much but really? That's 1.8 litres per week.

Its still a tiny, tiny amount compared to running a 30k car...

If you'd have bought a Polo GTI (for example) you'd have been saving a lot more! Or walk/cycle the 3 miles?

Thanks for all the replies, I think you would be right a Polo GTI might of been a better choice. I had not done any research into Euro 5/6 diesel and DPF prior to taking on this 3 year contract hire. I went from smoky old MK1 Leon FR 150bHp that was coming upto 9 years old and having read the VW brochure decided the GTD was the obvious upgrade giving a performance upgrade & better advertised fuel economy. I put the better figures and higher performance down to the weight saving over the Seat. think it was nearly 100kg lighter.

But then reality happened and I realise they must get these figures on a hot engine under perfect conditions unlike a 3 mile commute in heavy traffic and freezing conditions and I'm constantly throwing extra fuel into the exhaust to burn off the soot.

Your right its probably only costing me a couple of quid extra per week but what does annoy me is that the government gives me an advisory fuel rate that I can claim for business mileage use at just 11p per mile currently without having to declare any BIK on it.

The reality is that it is costing me say 17p currently to nip to see a customer locally.

Only another 2 & 3/4 years and then I will have to do my homework and probably look at a petrol machine.

BTW, from my latest journey, from over-night cold, the first 3 miles I got 39.8 mpg.... but the ambient was 11.5 Celsius by the time I left for my first meeting this morning (grrrr bloody kids!)

I reckon once ambient temperatures get up above ten degrees, the initial crappy warm up period is massively less....

However, definitely do not buy an oil burner if all you do is short trips!

That type of trip wont do either engine any good. I think a Golf GTE would be more suitable in these circumstances.

Get the GTI, otherwise one day you'll find yourself side by side with a Peugoet 208 GTI on an uphill stretch of dual carriageway and they'll destroy you. This happened to me today.

Miss my GTI.

Must be something wrong with your gtd then as it's got way more torque than a 208 s4itbox.

[andrewparker]

My GTD is a fit as the day I got it, but the fact is that 208 has way more bhp/tonne (173 vs 134) and weighs over 200kg less.

And without stage 1 at gti wouldn't make much difference?
