Re: STR on ASR off what a car !!!!!!
3.0V6 manual 'box with STR switched on, I reckon I get between 25-30mpg on an open A road, 28-32 on a good motorway run. Around town with traffic I get between 15-23 mpg. Could be better, I know, but not bad considering it's my daily driver which I use for work, and my job as a building inspector invlolves lots of stop-start driving every weekday.
I only switch off the STR when its icy/snowing, or in a long slow-moving queue or traffic jam.
In my opinion, when the traffic is flowing freely, it is a lot easier to drive smoothly and sympathetically with the STR switched on. The V6 has bags of torque and a gentle touch on the throttle and gearbox is richly rewarded. The car feels sluggish and unresponsive with no STR, even a on a motorway - at least mine does - maybe yours is better. I like the security of having instant and predictible power when road conditions can change in an instant. Sure you can provoke the STR if you stamp on the throttle, but how many times do most drivers have to do that each day? It's not just overtaking, it's quite possibly every time one pulls out onto a busy roundabout or from an urban side road. Can switching off the STR and then stamping on the throttle 10 times a day really be good for fuel economy?
I can't for the life of me understand why anyone would not want to use the STR. It's an Alfa V6. If I wanted a sedate drive and fuel economy I would have kept my Passat TDI, which regularly did 50-60mpg under the same driving conditions, but nobody ever said to me 'nice car' and I never switched it off at the end of Fosse Way/ Inverness road, Brecon Beacons etc. and thought 'I really enjoyed that drive'.
If I had known how bad the economy was going to get, I probably wouldn't have bought the 166 when I did, but I did buy it and with the depreciation being so huge I'm going to continue driving and enjoying it whilst I can. Engines like this will be outlawed soon.
Switch on the STR - you might just enjoy yourself.
