I have this feeling on my MINI, but the detent is not present on our 2013 2.0 You can really mash on the peddle and get a 2 gear downshift no problem, but not it sounds as if mazda put a slight tactile feel in there to help differentiate downshifting 1 v s 2 gears. It makes sense, with how quickly these cars upshift; if you need to go-go just press harder, not you know you are pressing harder.
