Had my first noticed GPF regeneration the other day. On a stretch of my commute, about where the engine comes up to temp in our weather, the fuel consumption started rising, where it always starts falling. At first I figured it could have been a head wind, but flags were hanging down, no wind at all.
I ended up with 15% more consumption before it started dropping. The car didn't do this the morning before or after btw.... But with the cold weather, dropping fuel consumption in general and low traffic at the time allowing for an efficient drive I can see how the GPF might not have gotten hot enough on it's own for a while.
