Poor fuel ecomony on a 2013 1.6 VAG diesel
Discussion
My wife took delivery of a 1.6 TDi Audi A3 as her company car earlier in the year, for her spec was priority over engine size hence the 1.6, being truthful it's more than adequate and will happily sit at M-Way cruising speeds.
She is currently sitting on an average of 55mpg, this is after 18k miles in 9 months so the engine is well and truly run in, tyre pressures on the 18" wheels are fine and her driving style is best described as 'sedate' Of her 50 miles to work 40 miles are on M-Way and she has no need to to anything other than sit at 75mph.
I waasn't expecting to achieve the mid 70s claimed figure but mid 50s is disappointing, especially as she drives in such a chilled out manner.
I'd be interested to hear what other owners are achieving.

Won't the extra-urban manufacturer figure be calculated at about 60mph?
If she tries her drive at that speed then she may get closer to what she's wanting, but 55mpg sounds there or thereabouts to me?
Although I have to say this thread is doing nothing to move me back to diesel, on a very, very long motorway drive at 70mph (and assuming no heavy traffic) I get 41mpg from a 2006 Mondeo 2.0 petrol.
Granted my 21mpg round town figure is more painful

I have the engine in a Golf which is used for deliveries. Daytime doing longish runs at a cruising speed of 60mph I only get 50/55mpg. At night it's short stop/start stuff and the mileage drops below 40mpg. The average (I do about 30k a year) is 43mpg. Never believe the makers' claims, and tell your wife to ease back on the motorway to 60mph and it'll get a whole lot better. Just leave home earlier.
(BTW she could try using the computer calculator on the end of the wiper switch which will tell her what she's averaged on that journey, and what she's getting at that precise moment).

Have a look at this current thread - Average speed for the Extra urban cycle is 63kph

My brother in law has that exact same car, but on an 11 plate, he gets mid/high 40's all in. Not having a 6th gear kills it he says.
Also, you have to give it a good old toe-full to get it moving, which doesn't help matters at all. The few times I've been in it it's felt pretty underpowered, albeit it 4 up with luggage being taken to the airport etc. Easy to get caught out of that small power band.
I think getting 60's/70's mpg from it would be nigh on impossible on the typical ebb and flow of a British road these days.

Accelerate to 70mph and then slow down to 33mph for 4 miles averaging 39mph over the journey. This is in ambient temperatures and with the car already up to temperature, a diesel can take 30 minutes to get to temp in the winter.
I was lent a 1.4tfsi sportback and that returned 48mpg over the time I had it, which was exactly the same as the 2.0tdi 3 door I was lent the week before.
It was up to mid 50's on a steady motorway run, very impressed.
