GTD vs GTI vs R urban MPG (from cold)

[Dully]

Good test for mine today with a clear run on all roads.

GTD, DSG with 7,500 miles.

Straight out the garage and on the road with no need to de-ice, -0.5 outside, 2 miles of B road, 13 miles of A road, 15 miles of motorway and finish with 2 miles of B road and parked up, most of journey managed on cruise.

32 miles journey
48 mph average
40 minutes travel
50.1 mpg

These are middle of the road for this journey, seen up to 52 mpg and as low as 46 mpg depending on traffic and my right foot, pretty pleased with this.

I wonder how the 7 speed stacks up against manual

If it is the same as the 7-speed in the new Audi A4, it'll make a difference because 7th is a true overdrive gear. I would say the first six approximate to the Golf GTDs ratios and 7th much longer. My g/f's A4 Avant 190 TDI averaged > 53mpg in France at 130kph, as I said earlier my Golf in similar conditions would struggle to make 45mpg...

Took the car into town today. All country roads ,freezing temperatures. Seven miles and by time got to town oil temperature showing 40 degrees and fuel averaging out at 32. Water up to 90degrees within two miles. Car had not been used for two days and left outside so quite surprised how quickly it warmed through .

I have 1 mile of single carriage road, 8 miles dual carriageway and then 2 miles at 30mph. 11 miles all in.

I've always tested my MPG at a point as I come off the dual carriageway.

What I've found makes a big difference is the first stretch of dual carriageway I hit just a mile in to my journey. If I go sedately it really sets the MPG up for the rest of the journey.

I can hit the following coming off the dual carriageway in these wintry conditions.

GTD 51mpg
GTI 37mpg
R 32mpg

A good stretch of it is downhill.

We discussed the new 7 speed DSG on the facelift thread. It would appear that it is more than just a 7th gear overdrive. The figures for the facelift Golf R show improved performance, improved extra-urban AND urban fuel economy.

However, if you look at the figures for the new GTD, the new DSG is showing much smaller gains compared with the manual.

It will be interesting to see the figures for the GTI performance pack. Especially if the standard GTI is still available with the 6-speed DSG.

Wasn't there a graph somewhere that showed speed vs revs in each gear for old DSG vs new 7 speed  DSG or Manual vs New DSG? It showed gears 1-6 a bit shorter than they were before, with a really tall (relatively) 7th gear. I doubt the first 6 ratios will approximate the GTD's on a box intended for the GTI or R - they'd be much too tall. There's a big gap between the R and GTD in both manual and DSG like for like - R is happy maintaining 4th with no load doing 20mph on the flat - the GTD would be unhappy doing that at any less than 30.

13 mile commute to Manchester from south Warrington, mixed roads/speeds.
From cold
CS40 manual 33mpg (taking it pretty easy)

... page 40 of the facelift thread - new S3 7-speed Stronic vs manual...

If it's like the S3 7 Speed then the 7th is really just an overdrive with very slightly shorter gearing from 1-6.
However with 1st and reverse now on different clutches it makes slow speed manoeuvring quicker.

Here is a graph I did showing the different ratios between the 7 speed s-tronic and the manual in the S3

In this weather 0ish,  from a garage no defrosting 5 mile journey,  speeds of 40,30,50,70,50,30. 22-27mpg. No ac,  heater on 20, heated seat on for a couple of mins until it's warm.  When it's warmer 28-32mpg
