Re: Twin-Air MPG

My driving has now changed to a commute including around 7 miles of stop start avg. 20 MPH town driving with loads of traffic lights, 3 miles of steady country driving and probably another 7 miles of extremely hilly country driving. My opinion of the TA has now changed from quite positive to very negative.

The TwinAir can not cope with this properly in terms of economy and the MPG has collapsed - i.e. 36 MPG average. I am not driving it really gently but not driving it very hard either, just keeping up with traffic. The performance is fine. I'm sure a small diesel could beat this by >50%.

It has conked out a couple of times a few seconds after starting on cold mornings, seems like a software problem, it doesn't give itself enough revs to maintain idle.

If you almost stall it when pulling away and then sit, there is a software problem where the engine can sound as if it is going to stall/struggling with no pedal input, you have to prod the throttle to restore the idle. Seems like another software problem. Hardly ever happens of course but you could make it happen again and again if you wanted to.

I only have another month to live with it. The car is nice with a very nice spec and is a nice place to sit (well, apart from the seats..) but the engine is unsuitable for my new commute. A car engine should be well rounded and suitable for a range of different types of driving...

I'd disagree, especially in the winter months, Diesels are awful for short journeys. Even in the summer I'd hate doing a journey of less than 10 miles in my Diesel as it still took that long to properly warm up and be at its best performance wise.

Re: Twin-Air MPG

Journey is those distances added together so about 17 miles in 40 minutes.

Useful feedback thanks for posting.

We are starting to think about which model to get next time around even though it will be some time away yet and I am increasingly even less inclined towards a TA than I was six months ago.

To me (assuming they are still around at the time) it will be a toss up between another 1.4 0r a 1.3 Multijet Diesel.

Re: Twin-Air MPG

Don't do it mate.

The real world MPG on hilly roads and in busy traffic is absolutely crap.

36 MPG indicated average for a tank driving normally (too busy to drive too fast..).

Really looking forward to March when the new car arrives
