Title: New GTD - more power - better fuel economy ?
Post by: Sootchucker on 08 June 2016, 11:05
Hi guys, as you may know, I've had my new GTD for only 3 weeks now and due to being abroad on business, up to last weekend, it only had 180 miles on it.

Well I went with the other half on a long weekend to see our best friends in South wales (a round trip of 400 miles). I went down the A483 from Cheshire to South wales (rather than use the motorway), and it gave me a good length of time to get an impression of the new car.

Firstly, and this may be in my head, but the car just feels a lot faster than my older car, it accelerates really hard straight from the off and although I was keeping the revs below 3,5k, really seemed to have some poke for a brand new engine. I take it the removal of the rear silencer on the Sport and Sound pack adds nothing (that's noticeable anyway) to the power of the car ?

I've also noticed that Eco mode is much more usable. Before the power would seem really strangled and horrible, but now in new Eco mode, it feels quite similar in power to Normal mode, but gives the additional benefit of the coasting mode on a trailing throttle, which really adds to the economy. I can only assume VW have modified the map on this mode ? Think I'll be using this mode much more than I did in the White GTD.

Second, fuel economy. In the white GTD, it took around 5-6k miles before it started to loosen up and I started to see over 50mpg average, with a best ever in 25,000 miles (over a long journey of 420 miles) of a genuine (calculated) 56.7mpg (mine was and still is a DSG by the way). In the new GTD with only a couple of hundred miles on it, for the 400 mile round trip, I average a genuine 58.9mpg (computer showed 59.7). Quite astounded with that for such a new car, and if it continues to improve as the miles pile on, a genuine 60+ mpg seems attainable.

All in all, loving the new car even more (if that's possible) that the older white one  :laugh:

As much as I like my Tiguan I want to be back in a gtd asap.

I'm pleased to read the MPG will improve!

My DTUK'd car has averaged 460-490 miles on a full tank. Brimming it each time has taken ~45litres so I calculate that to be mid-high 40's mpg.

Not bad given the engine only has 2.5k on it.

Be nice to have it top 50mpg given the Mrs predominantly drives it & it gets a fairly easy time when she's driving....

Quick question - does your new car have sport and sound and the old one not?

Yes new one has Sport and Sound package old one didn't.

Interesting you've noticed this as I did way back when.

We test drove a non sport and sound car before ordering our GTD. It drove very nicely yada yada but when ours turned up it felt so much quicker and urgent than the test mule.

I can only put it down to the (almost) straight through exhaust and the lack of back box. The centre silencer is slightly longer but then that's it, a straight run to the back of the car with the noise maker feeding in on a Y piece.

The only other explanation is that the map is different on S&S equipped cars but this we'll never know whilst VW can't describe what you get properly  :grin:

I did mention it on the S&S thread I think when I posted pics and video but didn't make much of it as I wasn't sure originally if I'd imagined it.

The 150ps lump seems to have improved over early MK7 standard 2.0TDIs, very eager in 2nd/3rd, still flat in 5th/6th though. I'm in a courtesy car right now (Limestone Grey R line TDI) as the R has gone in for a few small warranty issues that I got the garage to look at while the car was getting its first service. It has the novelty spec add-ons including the autopark, but the system has abandoned 2 of 3 attempted autoparks - maybe I drive to close to the scanned car that I park behind?

The R-line managed an impressive 57mpg on my 20 mile commute even though I caned it at every opportunity, (usually get 32-34 in the R).

Missing the R's immediate response though, I think i'd be wanting at least 240ps to go back to a TDI in future for the primary car.

Best I saw in my manual GTD was a 200 mile round trip to Leeds from Newcastle - almost 59mpg doing 80mph on the motorway with the aircon on in the height of Summer.

Don't fancy the new Tiguan Chris? - looks very good as SUVs go, like a miniature BMW X5 everywhere but the front end. Not sure whether I want to tie all that money up on my next car - if there's a decent lease deal on the next one i'll be all over it.

New Tiguan is just way too expensive Matt and that's before the 190 and 240 have even been released yet. Even with big discounts it's still very expensive.

Expensive yes Chris, but I was back in my dealership the other week and they had one of he first new Tiguan's to arrive in the UK.

A 2.0 tdi 150ps DSG model in metallic blue in SEL trim (so Pano roof, 19" Alloys, Active dash etc), and I have to say it looked REALLY nice.

Had the option as well of the Heads up display which the techie in me loved  :cool:

If I spec a couple of goodies like camera and 360 view a 150ps R line comes out at about 37 grand give or take. I'd rather be in a m sport BMW or s3 for that money. Actually a golf would be fine with loads of change haha

wow, just over 700 miles on it and I got this on the way home from work last night. OK, ambient temp was good, I wasn't thrashing it (around 65-70 on the motorway), but still plenty of traffic light stops. I got held up as well ½ mile from home and at the time it was showing over 65mpg !

Took me around a year after getting the white one until I started seeing over 60mpg !

If you're PCPing then it's all about the monthlies rather than the sticker price, and the monthlies are strongly influenced by the GFVs - looks like a straight 50% on the Tiguan, which makes a 150ps 2WD R line a pricey £500 a month. Might be worth looking at the lease deals if/when they come through if you want one Chris.

For £31k i'd expect the 184/190ps TDI engine and 4WD in R line trim, the new Tiguan is very over-priced.

Excellent economy. Under very similar circs a few weeks back I managed 50.3 in my GTI over an 18 mile route. At the end it was still slowly improving so could've been better, who knows where it would've got to? Generally I get up to about 45 which I'm more than happy with.

That's really impressive and when got my R itch over would not hesitate to select another GTD. If circumstance changed also and had to select own car it would be a bee line to the GTD even used.

Think you have the perfect all round car now with the later model additions and the quicker response/economy.

Wonder if the ECO remap applies to the R as motorway is certainly a place where not looking for performance and be happy to cruise along in ECO.

There is an ECO mode on the R, but it doesn't really do much. The GTD purrs along at 2200rpm at 80mph, the R is doing 3100rpm at the same speed - that is always going to cost you a lot more fuel. The R is not an economical cruiser, but around town it needn't be much more thirsty than the GTD. I was stuck in some bad traffic today and my commute took twice as long as normal, still ended up getting 29mpg as opposed to 32mpg, the GTD would've managed about 36mpg in the same sh!tty traffic.

That's very true and hence why my overall figure just creeps over 40 mpg as it demonstrates my mileage drop off and behaviour where most journeys are between towns or local with the occasional long distance cruise where the GTD really earns its corn as you see the mpg increase by the mile.

My main drives are in the economy region you describe and if R replicates that in some way I will be more than happy.

It was noted elsewhere that the stop/start is a little sharper now, even cutting out the engine literally as the car stops opposed to the slight delay.

Obviously be seeing the range of my economy from the extremes of pushing the R and nursing the R.

Though this is the GTD section will say its with some sadness that seeing the GTD go, if someone said you had to keep it another couple of years would have had no issue keeping it (company lease dictates change and hence given the R a go)

Has anyone fitted an induction kit on their GTD or K&N panel air filter?
