GTD vs GTI vs R urban MPG (from cold)

[Sootchucker]

Hi guys.

The following is for nothing more than my own curiosity and a bit of fun, but whilst I'm really happy with my second GTD, and the fuel consumption overall (at just over 45mpg) with a best of 62.4mpg is what I expected, I was just wondering with the really cold mornings and frost here, what others are getting from their petrol GTI's and R's under the following conditions.

Cold start, frosty morning (so a few minutes of the car running to clear the windows etc). Approx 10-15 mile journey a mix of urban (major town / city driving) and 50-60mph dual carriageways.

Under the above circumstances, by the time I arrive at work (approx 20 minutes and 10 miles), the water temp has already hit 90 deg C, but the oil temp around 70-80 deg C, heated rear window, heated front window (god I love this), heated mirrors all on for the first 5-10 minutes, full lights on, heater on (set to 23 deg C) for the whole journey (but AC off) with auxiliary heater set to auto , and heated drivers seat on for most of the journey (that's a lot of electrical load), I'm getting approx 37-42mpg (depending on traffic lights etc).

How does that sound against other GTD owners and more importantly petrol GTI and R owners ? I would expect the quicker warm up of the petrol engines to have a significant benefit, and certainly against a GTI, wouldn't expect much of an advantage (maybe a few MPG better on the GTD only) ?

Like I said, for no other reason (honestly  ) than my own curiosity, as whilst I have a couple of years left on the GTD (and in no hurry to change it), I honestly think with the governments change in stance over diesel engine cars getting stronger, this will most likely be my last diesel engined car as petrol engine vehicles have made such great advances over the years, and my thinking is that in a few years time, they won't be far behind where diesels are today (and cleaner to boot) ?

Morning Sootchucker

With owning a GTI, I do get a little less MPG than you, at the moment I'm averaging around 30-33 mpg on my run to work also depending on red or green lights, and its a mixture of driving just like yours (mines 15 miles about 30 mins)

Did an airport run for family member at 5 am yesterday at -2 degree

About 10 miles each way and mixed driving with some traffic lights and Queuing at Airport end.

the outbound run was 25.8 MPG and the combined run home totaled 30.2 MPG

To be honest its hard for me to tell how much the weather is effecting as only had the car since late October at 2700 miles (900 miles a month)

My average figure over all driving in that time and maybe 65% local is 24.9 MPG - expect a few 100 mile each way journeys through next year and particularly in summer as visit daughters so given understand the car now confident that figure will climb into 30's

My high was 39 MPG on motorway of which think could push over 40 if tried as that 39 MPG was achieved without any eye on economy.

My low is 17 MPG over an extended fun distance

The R is not bought for economy but if you stretch its legs a reasonable amount of the time you will achieve plus 30 to mid 30 MPG and for a car of this performance that's pretty decent

However if you stay local expect mid 20s and no higher as an average the average mileage only starts climbing when you are rolling along at constant speeds.

My GTD was giving me 37 MPG at times where was predominately local and 55 MPG on long runs.

No regrets getting the R though its a amazing car and aside from commenting on these forums on fuel as we share our experiences for others do not really give the fuel much of a thought as its just a little more each month from GTD (as would expect) and am just enjoying the experience of the best car personally driven.

Forgot to comment on Diesel cars as think you a spot on, what with the London air quality warning yesterday there is a scapegoat going to be sacrificed and that is ever increasingly going to be the Diesel engine.

Think the current Diesel engines may miss first wave but 3 years from now? a real clampdown, not just on C02 but Nitrous Oxide also.

Of course technology moves at a pace and maybe new tech will clean up diesels to new levels but think more likely petrol tech reduces emissions to new lows and hybrids replace the diesel as most economical drive as well as being cleanest on road.

This weighed into my decision to get an R now as even though emissions are 159 and comparable with some standard Vauxhall you can see anything over 90-100 being hammered in future years and there was a now or never feeling for me in a lot of areas including this.

Going to be interesting to see how plays out.

Hi.

Doncaster to Dumfries 220 miles avg 39.9 mpg. It just would'nt push over. GTI PP 6500 miles on the clock.

Home to work. 7.5miles avg from cold 32

19 miles each way to work, some stop / start traffic, 50/50 urban / dual carriage way, according to the computer see regular 37 - 40 mpg's to work and back depending upon how heavy traffic is or how much I put my foot down.  On longer trips - did Keswick last week (75 mile trip each way) - low 40's mpg in winter.  In summer add a few mpg extra.

Manual, non PP

Ignoring the colour quote as obviously red is best in every way

In the spirit of assisting a fellow forumite, I undertook an unnecessary detour on my way to Tesco today (other supermarkets are available though not round here ). Started from cold, no ice scraping required just a wipe over to remove that that had already defrosted. 2C on leaving, 6C on arrival at destination. Didn't need the rear screen demister but put it on for a while anyway. 15 miles, some stop/start, mostly 40 mph roads and a brief peak at 80. No motorways. Average was exactly 35mpg. Had it not been for some traffic in the last half a mile then 36-37 would likely been the result. Real bonus though was that finally they had my undyed kippers back in stock

Could be true but everyone knows Red is the fastest..

9 mile journey to work: 30-40mph zones start-stop at lights then quick 3 mile blast on motorway then another 40-30 zone + lights, 15-18 mins, get around 37-39 mpg in my GTD. A/C is never switched off, auto 22degC.
