Dan:

Your 50mpg might be one of a few things – the weather has warmed up a bit and everyone is seeing better mpg as a result. For the last week or so, when the temps have gotten up to 9 or 10C, I have seen my car get 5% higher mpg than when the day has started at 1 or 2C.

Your commute plays a big factor – the shorter the average journey, the lower your mpg is likely to be. Around 0-2C, my car is taking about 4 miles for the water temp to get to 90C, and about 8 miles for the oil temp to get to 90C. Doing less than 8 miles a day, your car won’t be fully warm by the time you reach your destination, the car is running much less efficient when cold and soot generation is higher, which will fill your DPF and force regens. I have a 12 mile commute, and I have noticed a huge improvement in mpg and regen frequency when I up my miles a bit. If you do 15+ miles for most of your journeys then you should be seeing 50mpg indicated, even in the winter, and most of your regenning will be getting done passively.

Your first regen will stink, it’ll smell like your car is on fire! Most people get their very first one at about 200-250 miles, and then it seems to be anywhere between 200 and 500 miles thereafter, depending on how short your journeys are (and therefore how quickly you’ll fill your DPF) – your car will idle at 1000rpm and not the usual 800. There are other things that will prevent stop-start working, related to battery load. If you’re at a standstill and you’re using your heater or aircon more than a smidge (or heated sets etc) whilst the dipped beam is on, you will usually find your stop-start not kicking in unless the battery is at a very high state of charge (90%).

Cheers for that. Currently doing 3mile journey each way to work with morning temp being between 4C-8C and evening 10C average and back and mixed driving around at night for a good drive. Not been looking at the oil temp yet, will have to keep an eye on that. I will expect for the first regen to happen when my Mrs is driving then and I get a phone call to say it is on fire  :grin:!

I also noticed in the 40 thousand page manual that the new engine run in cycle is up to 1000km and to gradually hard run it in between 1000km-1500km. I though that was quite low as it only equates to 621miles. Thought it would be at least 1000miles...

Dan:

 3 miles to work each way and you’ve not had a regen yet? I’m amazed, unless your other driving is long enough to keep the DPF clean. Running in really isn’t much of an issue any more with tighter manufacturing tolerances etc. Just drive it normally, babying the engine is as bad for it as hammering it while it is running in and after 1000 miles you can do what you like to it. I ran a TDI in badly once (picked it up from a broker and drove it on a 700 miles round trip all at motorway 6th gear cruising. That car had a thirst for oil, the mpg was crap and the power seemed on the low end of expectations for the car (Golf MK5 140TDI PD). The first 300 miles are most important from a safety point of view because it takes that long for the brakes and the tyres to be scrubbed in properly and working to their potential.

If you haven’t read much of the other threads, you might not be aware to avoid Shell V-power like the plague. It’s expensive but makes the car around 10% thirstier and less powerful because it’s got a lower density than regular diesel. The only thing it has going for it is that it’s clean (as fuels go) and might see you regenning a little less often. I’ve seen best mpg results on standard Esso and BP.

Some really interesting reading in this thread. My GTD is due in around 8 weeks. I've ordered a Tornado Red 5dr with manual 'box and am changing from a 2006 MK5 GTI which I have owned from new. Sadly I've had just about enough of the 22mpg average that the GTI returns and chose the GTD hoping that I can achieve a better balance of performance and economy. It's certainly encouraging to hear that the GTD can put a smile on your face but still do the economy thing well too.

Scored a record 56mpg on 12 mile trip home from work this evening.  Has to be the milder temp.

Last night though, on my way back from Newcastle me and an old shape Focus ST (221Hp/320Nm) were having a bit of fun for a couple of miles (the road was empty) on the coast road – definitely noticeably (but not hugely) quicker than one of those without even getting into the clicky zone of the pedal. Despite the spirited driving, I still returned an indicated 49mpg.

Funny you had a go with an old ST. On mg way to Hartlepool the other day I had a go with one and it rinsed me good and proper. Think a box is necessary, once I get my 10k out the way think it'll be going on.

How soon will your 10k be coming? My box went on at 5k. It was a friendly little challenge with the ST. We each had a blast from 70 to 90 in turn (4th gear for me, I assume he did the same), twice to see how quickly we could put distance between each other, then did one together. I was a few car lengths ahead of it. I'm sure he knew it wasn't a regular GTD after the first time. Blinked his hazards once before turning off for the A19 after our maneuvres.

The box is absolutely great, the extra go feels absolutely natural, like it was always meant to be there.

I reckon it'll be at start or middle of next month. Save a few pennies then put it on and get it lowered. That's the plan, it'd be nice to work out like that haha. My "play" was straight off a roundabout and then a 50-90 burst. Both of which he was easily out pacing me I'd say.

No doubt you know this from the know-it-all forum (overclockers) that not only are his statistics more favourable in standard trim, but the Volvo lump sitting beneath the bonnet of that Focus ST responds well to tuning and offers silly statistics for relatively little money. A tuned one would play with you like a kitten with a ball of wool.

I'd say pick your battles personally! I can't pick any as still running in. Desperately wanted to rinse a BMW last night.

I can well imagine if it'd of been tuned the result would of been even worse. If I'm honest I didn't really know the power of the STs. Thought they were in the 200BHP ball park. I'll be more careful in future!  :laugh:

Yep, the Volvo T5 lump has great potential, and my GTD is realising its own potential right now with the box. VW seem determined not to try harder with the TDI. They could seriously maim the GTD or GTI sales by going one of 2 ways:-

Bring out a twin turbo GTD with 220-230PS - GTI performance (if they can overcome stand-still traction issues) with TDI economy or

Up the GTI fuel economy by utilising ACT on the GTI lump - GTD economy (or close to it) in a GTI

My mate has a 1.4TSI ACT A1 and finds it very hard to do under 45mpg in most circumstances.
