Is my O2 sensor wideband?

Props to VW for thinking about economy at least sometimes.

My VW is not as efficient as it could be with a few design tweaks (especially much taller gearing -- it feels like it could use at least another 5 gears). However, VW did do a couple things right...

- DFCO happens instantly at speeds over 40mph.
- Open loop doesn't seem to get used except for a short time after the car is started.

I think I read in another thread that cars with wideband O2 sensors don't have to use open loop at WOT. Does this mean that my car has is wideband O2 sensor equipped?

I think I read somewhere that all recent VWs have wideband sensors. And this is consistent with what you noticed regarding open loop.
