The car was ordered in October 2014 and prior to delivery read every review I could find and watched every Youtube video so I knew as much about the car as was available. Still much to learn though. Here goes.

Took delivery of the (very high spec) car 7 days ago and so far so good. Local mileage all done on electric (ie 300mpg which is the max the DIS will indicate) having had the charging point installed by Chargemasterplc. Very good service so no complaints at all. Check out the grants available on the OLEV website.
Took the car on my 50 mile each way commute today with a maximum electric range of 26 miles at the start. The maximum achievable electric range on a full charge was 24 miles when the car was delivered but is slowly improving as the battery is charged and discharged. I achieved 64 mpg on the way to work and 67 mpg on the way back with almost 60% of each trip being emission free (ie no engine running). The engine is still very tight so more to be gained when it loosens up. No charging point at work (which is a power station!) so had to manage the electric bit very carefully. Most impressed with the hybrid auto function to achieve good mpg automatically. My journey is part fast A and B roads, dual carriage way and some motorway. 3 urban pinch points too which benefited the hybrid nature of the car very well. I drove it the same as my BMW 320D auto (E91 164bhp) which achieves about 45mpg.
With a little planning ahead and using the paddle shift to increase the regenerative engine braking as necessary (shifting the gear into sport also does the same thing) the car simply does not lose speed without putting energy back into the battery. Very impressive.
I was worried about the coast function but needn't have been. If the car is coasting having lifted off the accelerator completely it will not exceed the speed you were initially at. For example going down a long hill into my local town at 30 mph and lifting the throttle the car simply started charging the battery (akin to engine braking) without exceeding 30.
Very happy with the ride and handling too which I can declare is not too dissimilar to my former A3 2.0 Turbo sport quattro. Happy to take questions and to try things out on the car if you ask me. Else a further report in a few weeks.

I'm also most impressed with hybrid auto, which is the only mode I've used for longer periods.

Most of my trips are between 150km and 200km. With one full charge before the start of such a trip I end up with 50/50 fuel / emission free most of the time.

Today I drove 225.6 km, most of it with adaptiv cruise set to 90 km/h, 49% emission free and 51% on fuel and still 4km on battery available according to the meter. Fuel consumption on this trip was 4.2 l / 100km, a number my dealer told me should decrease a tad after some more thousand kilometers.

Just completed 350 miles with most of it emission free. MPG 89.9. As in my earlier thread my wife runs about locally and uses no petrol at all. I do a 50 mile each way commute and do about 55% emission free. Hence 89.9mpg.
 
Very interesting thread @TonyH50....

Just considering replacing my F30 320d with either Golf GTE or e-tron. What I get will depend on what my company car scheme will let me have. The GTE is on there and expecting e-tron to be added soon. I'd prefer the e-tron :yum:

My company scheme currently has the 320d Efficent dynamics at £120 a month tax and £70 personal contribution. The GTE comes out at £15 tax and £60 personal contribution (that's with every option box ticked!). Quite a saving! I'd hope the e-tron would be similar.

My commute is 50 miles round trip. I have a wall box charger at home and would be able to plug in the car at work on a 3 pin connection. I would hope with the electric mode I can save some £££ on my commute.

Do you use the e-tron as a family car? Is the reduced boot space an issue?
 
The boot space isn't really significantly reduced, most of the space cost is absorbed by not having a tyre well. beyond that it's negligible, you lose an inch or two floor to ceiling height, but it's yet to present anything I can't fit in that I could get in the 2014 A3 I had as a courtesy car while waiting for mine.
 
I've had the car now for about 5 weeks and totalled 900mi and have used around 50L of petrol which was mainly for longer trips. The remainder has been purely on electric, including a 2x per week commute to work in central London (Westminster), 15mi each way. Fortunately I can charge at work using the SourceLondon network and normally a space becomes free during the day.

I've done some longer trips in the car which is comfortable to drive with the family (2 adults, baby + all the paraphernalia - boot was full with pram, travel cot, large suitcase, large duffel bag + more crap in the front seat)

434mi return journey North London - Swansea (topped EV up at service stations twice and once at hotel). Motorway hybrid-auto mpg was hovering around 65mpg, with no AC.
140mi return journey to North London - Gatwick, hybrid-auto 50mpg - was driving with heavy right foot with AC.

Average mpg to date ~75-80mpg

I'm currently sitting with about 40mi range with the ICE with no intention of using it for the next few months, so hopefully the overall mpg will only go up :D
 
I would be interested in precisely how you are calculating those figures. After 3 weeks ownership I've done my sums and I am disappointed. Typically I will do several days of short all electric trips then 100 miles home on motorways, hybrid hold, and then a few more days of short electric trips. Between the first topped up tank and the last top up i subsequently did 879 miles and put in 70 liters, but 191 miles were pure electric so those 70 liters (15.4 gal) were burnt over just 688 miles. This gives 45 mpg
My 1st gen Insight now sits sadly in the garage but smugly reminding me that it would happily return 70 at 70, or 90-100 mpg at lorry speeds.
 
Figures were calculated using the onboard trip computer and verified by the amount of petrol I've topped up with. With now a few extra 100mi on the clock and mainly EV trips my average mpg is 95-100mpg.

I think your problem is that you are using hybrid hold, which basically relies on the ICE to do all the hard work and will return around 40-45mpg. Try sticking to hybrid auto and you'll see 65mpg at 60mph. As for the insight - are you sure the 100mpg is correct for a hybrid? I've only read reports of high fuel efficiency by tottering along at 20-30mph.
 
I'm not sure you are deducting your EV miles to calculate the petrol consumption. As you've found "a few extra 100mi... mainly EV trips " and your mpg goes up. If we only did EV trips this calculation would give you infinite mpg. Thanks for the tip re hybrid hold. I'll try that.
I've had the insight from new and done 120k miles. It is quite easy to achieve 90 mpg without being a nuisance on the motorway. And I have just the once pulled up at home with it showing 101.5 mpg after driving back home to the East Midlands from Gatwick. I have to confess that there was a tailwind.
 
No I'm not deducting the EV miles from my calculation and the metric mpg is not really suited for plug in hybrid electric vehicles. Maybe miles/££ would be better suited. Unfortunately the trip computer in the car is based on a combination of EV and petrol consumption and the only other indication for EV usage is kWh/mi - great if you are only in EV mode but messy in hybrid settings.

Basically I treat the EV use as free miles since at least 50% are topped up away from home and at around £1 for a full charge giving 20-30mi is pocket change (my commute to and from work) I'm glad I'm not spending 4-5x the amount on petrol.

That's basically the approach I'm taking, EV wherever possible, because even if it's not a free charge it's a fraction of the cost of petrol, despite charging almost every night it's not made a significant impact on my electricity bill so far, but obviously it's been over summer when usage should have been a bit lower anyway.
