Yes, you are probably right. I just relooked at the published numbers and my current 3.2L NA engine is thirsty, so probably nothing to do with natural aspiration in my case. My efficiency with the smaller turbo is probably because it is mostly used for the daily grind, where it doesn't often have to work hard.Bit of a myth actually...
My previous Ford 4L NA straight 6 was more efficient.
Other models using the same 4L engine were more thirsty, with the biggest difference being the transmission (getting me halfway back on topic). I'm guessing an extra gear or two can make a big difference to efficiency.
