So I sold my Ro last month and decided to do something diffrent.
The oil burning shit box turned up a couple of days ago with it's 2.2 dci motor.
My Ro did about 23mpg on a standard work run. The 'economical' option does 29.8mpg.
This on a car with about 1/3 of the power of my old Ro!
When speed increases to 90mph on 'German Motorways' the fuel economy drops to 24/25 mpg.
A Monaro will do at least that - and as speed increases I bet the Ro is more economical at like for like speeds.
So you can quote me on this :- A Monaro is more economical than a 2.2 diesel!

I am so pleased that you have posted this up at this point in time.

Last week my son and I bought in a 2l HDI car, and ever since buying it my son has been moaning that it does less miles to the gallon than his old Jap V6 3L.

Now, we were expecting to get 55 to the gallon out of this car, as that is what it said on the box. so with that in mind I went off to the main dealer to have a good old moan, and get what was ever wrong with it fixed.

Now the very nice person on the service desk said, Sir! you will never get the stated MPG figure, it will be at least 10-15 mpg less, WHAT!!!!

So delving into it a bit further, it turns out this manafacturer puts the car in a wind tunnel on a moving road so there is no rolling resistance, and calculates the MPG from that so they can come to the right emissions figure.

Sucks don't it, and yes you are right the faster you go in ro, the better the fuel consumption, I therefore suggest we lobby for a 100mph speed limit!

Have a great Christmas guys

I know, I know - 150 miles now, i'm sure it will improve but by how much 10%?
If so point still valid

Ive friends who run VAG Tdi cars ( Passat, Seat Altea, Audi A6 1.9 etc ), and my Dad has a new auto tdi Golf.

You would need to seriously abuse any of these cars to get less than 40mpg. Even the automatic Golf averages about 43mpg ( Although you could get less than that with abusive driving )

The others would be closer to 50mpg during normal driving. One even managed over 60mpg in his 110 Passat Estate, with some very frugal driving for a few weeks.. ( figures based on what the dash displays as an average )

There must be something seriously wrong with a modern 2.0 tdi that cant get above 40mpg ( unless you are stuck in heavy traffic all the time )

Even my crappy old mechanical turbodiesel 4speed automatic Volvo estate averages 31mpg. ( which is very surprising )

Sounds like you got the wrong 2.2 weasel.

We have an E class Merc 2.2 CDI and it does an overall avg of 46mpg compared to about 18 for my Monaro.

I have had this happen on a few diesels when they are brand new, after the first tank they tend to improve quite a lot.

Got a brand new Corsa CDTI 1.7.

Apart from having a steering problem which i`m taking to VOSA next year the car`s only doing 40mpg despite the book figure of nearer 60.

Vauxhall (local dealer) have said `yup that`s about right`

Hmmmmm!

Before the 'ro I had an Alfa 159 2.4jtdm. The best I ever got from it was 38mpg, the Q4 3.2 petrol averages 18mpg!

However, my wife's diesel Focus averages 50mpg. It seems if you get a "performance" diesel the fuel economy is the first thing to go.
