With my 156 2.0 TS I average 28-30 mpg and that’s only occasionally being heavy footed, so I suppose that's about right for a 2.0 Alfa, but I wish I could get more though. My old cavalier ecotec and Toyota Celica both 2.0, use to average 36 mpg and both were as quick if not faster than the Alfa. But did I love those cars like the Alfa? No, there's just something special about the car and driver relationship with Alfas, but if I had to change my 2.0 petrol in the future I would definitely look at the 2.4 diesel. It just seems the most obvious way to go, more mpg and the performance gains from twigs like remaps, make a much bigger difference over the petrol engines, they just seem more tuneable. The petrol 156 would need a bucket load of money thrown at it to make a real difference. a remap produces very little extra bhp, along with air intake mods, these just add up to a slightly more responsive engine with more linear power.
With regard to electric cars, I think they have a fair way to go yet, I think hydro technology is the way forward, but then we would be taxed just the same on water! It wont be long until we are taxed on the air we breathe, as so called global warming is blamed for poor air quality in the future.
But there we go, nothing is ever really new, all is just a circle, ever evolving, the machine of life just moves on relentlessly, while the rich rule over the poor and each little bee contributes to societies beehive. All we can do is make the best of our little blink in time and history. So, lets do it, lets get together in our masses and make our voices heard! How long will we be pushed around by these infidels in government, the time is coming for the peoples revolution!
