Everything seems to be DOHC lately, even the cheap stuff. Does anybody still sell a new SOHC 16 valve engine?

Was the Fiat 1.4l engine the last SOHC 4-cyl engine sold here?
Edit: I'm not positive, but I think the 1.3l engine in the fiat 500x is SOHC. In general, Fiat seems to have some SOHC, some DOHC engines.
I thought the Fiat was SOHC but with that freevalve setup or whatever they were calling it on the intake side. Solenoid controlled valves.
In general, I think SOHC with 4 valves per cylinder has gone away because VVT can be used as a fairly strong lever for emissions while retaining great power delivery characteristics. It is much harder to vary LSA with SOHC than it is with DOHC. Without varying lobe separation, SOHC makes more sense if you can get the rocker lever arrangement set up well.
