The TA is using some innovative way of manipulating intake timing, but uses the cheapest way possible of doing it.
Manipulating intake timing is not new, other manufacturers have been doing it for ages, but using an electrical on-off device like a solenoid to do it is something new for sure, let alone how long these solenoids will last in there.
In fact, using an on-off device and trying to modulate that (quickly switch it on and off continuously) in order to achieve something that could resemble analog variation, which is what you would want to have in the first place, just shows that the primary system design limitation is something like "make it work (sort of) and cost next to nothing" because everybody else has it and we must appear to have it as well, although we can´t really pay for it.
And in the process of doing that, why not lose one camshaft as well, these cost money too, lose a couple of cylinders and all associated parts that also cost money, bring the displacement at exactly half that of popular 4-in-lines so parts are already available and cheap, add a turbo and we are done.
What I am saying is that Fiat could market this thing as "look at our new engine, it is so cheap and it still works". Instead, they seem to think that consumers do not know enough to tell the difference, and they price the car accordingly. Well, I just don´t like that.
