can i ask another question the manual and the alfa boffens state a standard gtv will only do 30mpg so how are you quoting more then what they say it could do ?
i do very small commutes about 8 miles a day and only average 25mpg and when i was in england travelling down motorways between 80-100 mph only manage about 27mpg
on the reserve note the booklet says the we have an 8 litre reserve
I assume that was aimed at me?
Don't know what your GTV/Spider handbook claims but mine says 6.8L/100km for the "extraurban cycle which includes frequent accelerations, in all gears, simulating normal extraurban use of the vehicle. The speed varies between 0 and 120km/h." 6.8L/100km - divide 6.8 by 4.54 litres to get 1.498 British gallons. 100km is 62.1 miles. Take 62.1 and divide by 1.498 - that's 41mpg.
As I stated I can't use 120km/h speeds, and I accelerate gently, avoiding braking. Therefore, I get 43mpg. It does seem, though, that it would be tough to get any more than that.
The petrol I use is 91 octane, it's cheaper than 95. We can get 98 too.
I'd be horrified if I got less than 30mpg - come on, a Japanese car would be about that bad (Legacy, Diamantť, Maxima, Accord V6, all really thirsty). I've always found the Italian cars to be more economical than anything else the same size - not surprising when petrol in Italy is so expensive.
You could buy a diesel and I suppose lots of people in England do. Per litre, diesel is cheaper than petrol here, and yet we have few diesel cars on the road. Personally I don't like diesel - even when it's turbocharged, it's still like driving a truck (small usable RPM range) and doesn't 'feel' powerful (feels like it runs out of breath) though it is appropriate for something like the 1.9JTD Multipla I drove recently. I don't like the extra vibration and characteristic roar. I'm not convinced diesel is essential for fuel economy. A friend has a diesel Golf 4 (2003 I think) and it returns the same mpg as my 156. I know which one sounds nicer...
I think the point of this thread is to try and establish how much difference exists between the TS and the V6. Personally I've found a huge difference between the TS and the V6 but only in other Alfas. I haven't had a GTV/Spider V6 to compare against. I did have a chat to someone with a 3.2L Spider recently, and they said it was diabolical (18-20L/100km) but that's only anecdotal.
Hopefully we can compile more accurate knowledge.
As for my super-economical 156, it is a different version of the 2.0TS, with the electronic throttle, and seems to have more torque below 3000 than the one in my Spider. I think those higher revs needed are counting against my Spider's fuel economy, but I'm happy enough with it - 43mpg is what I used to get out of my 1116cc Uno 60 I had as a student
Petrol was much cheaper back in 2000 though!
