This is the question we get more than any other, and for good reason. Lasting 2 to 4 weeks is a specific claim, and specific claims deserve a specific answer about what that actually looks like day-to-day.
The short version: most Drive scents remain clearly noticeable for the full 2 to 4 week range, with the exact number depending on a few real-world variables, not a flaw in the product, just how fragrance and airflow interact.
Climate is the biggest factor. In hotter climates, or during summer specifically, fragrance diffuses faster because heat accelerates evaporation. A scent hung in a Miami summer will diffuse somewhat faster than the same scent in a cooler climate in fall or winter, which is simply how volatile fragrance compounds behave, not something specific to any one brand.
Driving frequency matters too. A car driven daily gets more airflow and more temperature cycling than one that sits in a garage most of the week, which means daily drivers will generally move through the 2 to 4 week range faster than occasional drivers.
Placement affects perceived intensity more than actual lifespan. A fragrance hung close to a vent or in direct airflow will feel more present sooner, since it is being circulated more actively, even though the underlying fragrance is diffusing at the same physical rate either way.
Here is what the actual timeline tends to look like. Week one: strongest and most noticeable, especially the top notes. Week two: the fragrance has settled into its heart notes, still clearly present but slightly less intense than day one. Weeks three and four: base notes carry the remaining scent, softer but still detectable, especially to anyone who was not already used to it.
Compare that to a traditional single-note freshener, which tends to peak in the first day or two and noticeably fade within a week, since it lacks the layered structure that allows a real fragrance to diffuse in stages rather than all at once.
If you are hanging a new scent, do not judge it entirely by day one. The first impression is real, but it is only the top notes. The fragrance you will actually be living with for most of those 2 to 4 weeks is the one that emerges after that.
