Okay. Thanks Jochen. Alex, just to add a little bit more color on your question. I think in Q1, gross margin came in at 31.2%, which compares to 35.8% in the prior year. So obviously, as you look at that, a decrease of about 450 basis points, that was driven by lower operating leverage and the revenue factors that we walk through on Page 7 in the deck. So we have some more materials on that. We obviously -- as we look at the gross margin, as we move forward, we do envision modest cost inflation of something that's around 2%. So about where we were last year, maybe up a tiny bit from an inflation standpoint, certainly down pretty meaningfully from 2022.
And hang with me here, as I explain some of this, but the majority of the units that we ship in the first quarters. So think about 2024 and 2023, those were produced in the preceding fourth quarters in advance of the new model year launch. As we sort of try to put this into perspective, production volumes in the fourth quarter of '23 were down about 24% compared to the fourth quarter of 2022, which results in a higher fixed cost per unit on motorcycles that end up getting shipped in, in the respective quarters.
That unfavorable impact of the lower operating leverage is offset through productivity savings in the latest quarter were primarily related to logistics. There was also a little bit of mix noise in this quarter between motorcycle, P&A and A&L. And so the kind of complexion or makeup between motorcycle P&A and A&L causes some uniqueness as we analyze the dollars, so favorable dollars and unfavorable percent that really expresses the additional dollars from the motorcycle mix with a decreasing mix from A&L and P&A which have typically favorable margins.
So good question. I think, a unique situation in terms of where we are. And then as Jochen touched on, when we sort of flow that gross margin guidance, all the way through to sort of OI margin and what we envision on that front. We came in at 16.2%, which is above our full year expectations, and as Jochen touched on, in line with expectations for the quarter. So hopefully, a little more color probably than you asked for, but hopefully, that helps explain where we are.
