Title: ED30 MPG
Post by: Snooze on 20 May 2012, 10:59
Hi guys, please could someone tell me what the book mpg figure is for the ED30?  The book mpg figure for the regular Gti is 35.3

I will be getting a new car in December and just wanted to compare the ED30 to the regular Gti in terms of running costs.  I currently average about 30mpg in my Gti.  Cheers

I cant imagine it will be must more. Probs a couple MPG lower as its the same engine just with a bigger turbo on it.

I can tell you what it really does if you like around London 17-18MPG :sick:

My morning commute is about 11 miles and the computer shows I get 33 ish. On a longer run I can often achieve 37 ish. That's doing a steady 50-60.

Thanks for the replys. Looks like I'll be able to get an Ed30 at Xmas then, so long as I can find a gd one!

I just had mine serviced and noticed a considerable increase in mpg... bonus  :laugh:


let me know and mine may be up for sale then  :wink:

Er no, cold air equals more fuel request unfortunately ... Cold fresh air gives better performance, thus will use greater fuel request to boot.

Lifetime average fuel consumption for my old ED30 was 18.7mpg over 30k miles. Although my old ED30 was far from average :laugh:

Im not sure I follow. If the air is colder i.e. more dense, then should the engine not run more efficiently? I can see why it would use more fuel if it was pedal to the metal, but for everyday driving would you not see increased mpg?

I was about to try and write this all myself but then tought someone else can do a better a job so looked on Google

All vehicles have an optimum operating temperature, and the colder it is, the longer it takes to get there. While modern engines make very efficient use of the fuel mixture entering the engine, they rely upon the oxygen sensor to monitor the O2 content of the exhaust, as well as sensors for manifold pressure, mass air flow, throttle position, and coolant temperature, among others. All of this information is communicated to the vehicle’s computer that continually adjusts ignition and valve timing as well as fuel injector pulse width, to fine tune the amount of fuel delivered to each cylinder. This is done many times per second. But here’s the caveat—this engine-management system is only at tip-top efficiency when the engine is at full operating temperature. And when the mercury’s showing low, all vehicles require longer periods of time to reach that full operating temperature—and it’s in that warm-up period that efficiency is lost.

Add to that the common practice of making short trips (to minimize running to and fro in sub-zero temps and wind chills), and each time your vehicle cools down it has to come back up to optimal operating temperature. It all takes its toll.


There are also loads of little things like using the heater, the windscreen electric heater, the heated seats and the colder temperature also lowers your tyre PSI, all the little things then add up to take away that extra MPG.

So... if in both situations the car is upto running temp. Which would run more economically?? in cold or warmer air?
Title: Re: ED30 MPG
Post by: AlanD on 06 June 2012, 12:51
Warmer, colder air means its more dense which means there is more oxygen which means there is more combustion which means there is more power which means more fuel is used.

Prof Brian Cox doesnt have sh!t on me.

Im not so sure... more power available from the fuel used would mean that you would need less 'go' to achieve the same speeds.  :undecided:

Anyway... what do you know diesel boy  :laugh:

Alan , you are correct
Title: Re: ED30 MPG
Post by: Saint Steve on 06 June 2012, 17:04
warmer air temps will result in the engine getting to optimal temp quicker, thus resulting in more efficient fuel economy.

Colder days will do the reverse . ECU will alter the amount of fuel induced Due to the density of the air being more dense.

Gilly, if you still don't understand, then google performance of a petrol engine in terms of efficiency fella.

I can't think of a better way to explain it. All I know is I get at least 3mpg better dueing the summer months. :nerd:

Because its a company car. The A3 emits 119g/km which means get a nice healthy £405 a month towards the car. The ED35 / GTI emits 188 g/km which means I get (I dont have the PDF on this laptop but its hardly anything).

The lower the CO2 output, the more money I get towards to motor (hence it has to be a diesel).

If you get a prius do they have to pay you to drive it?

Mine is a mkv with a K04 +, about 335 bhp(290whp), and I'm averaging 28.6 mpg for the last 2300 miles.

Nice figures. I've just gone and checked and for this current tank of V-Power, I've averaged 28.6 also! I will probably get around 360 miles to the tank.

The other day I filled up and drove from Bow in East London to Salcombe in Devon, in somewhat of a frantic dash. 241 miles in total. 3hrs and 5m total duration. Average mpg = 19.1. Total mileage from tank = 246

And it was whole lot more fun than ambling along 70mph trying to breach the 30mpg+ barrier!

A day at the track usually brings my mpg down to 20 average real quick. Must have had loads of fun that day, yes?
My mileage was reset last week when I had the DSG filter and oil changed, but it again is right at 28.6 mpg at 480 miles.

Are you saying you can get 480 miles from one tank?
Title: Re: ED30 MPG
Post by: R32UK on 20 July 2012, 15:03
I doubt you could see 480 miles. ALthough i did get something like 440 from my mk6 gti.


Best I have had on the ed30 is 390... had to coast into the petrol station  :lipsrsealed:

Post by: carl1 on 20 July 2012, 16:04
I got 440 out my ed35 down to cornwall, a boring 70mph most the way but 3 up and lots of luggage. Computer said 38.7, not bad really as same trip in my mk6 gti was 480 (before refill). Ed35 has over 10 % more power and apparently a higher ratio final drive than the standard mk6 gti. So maybe the mk6 is not as efficient as we all think.

No No No. I'm just saying that since the battery was disconnected, thus clearing the memory 2 - (over 3k miles were on the memory 2 and avg. mpg), that now over the last 500 miles it is again averaging 28.6 mpg.
I think we got 440 miles/tank on a trip last year where we avg'd 31.9 mpg for 1200 miles. I get 400 mi./tank now.
