The psychological effect of the new car smell is undeniable, but it's difficult to explain because there are multiple layers of psychosexual factors involved. The most basic level is that we associate the smell of something clean and fresh with safety. We feel safe when we know where things are, what they look like, and how they work. This applies to anything from food to clothing to cars. When you open the door to your brand-new car, the scent fills the space around you, enveloping you with feelings of cleanliness and security. It feels good to be surrounded by something so pure and untouched. On top of this base comfort level comes an underlying feeling of power. We all want to control our environment, especially in relation to things that move. There's something inherently attractive about being in charge of a machine with no personality attached. You can go anywhere you want without having to worry about someone else telling you how to behave or what to do next. This sense of autonomy is amplified by the fact that driving represents a major milestone in many people's lives.

We have our sexuality. The sound of the engine revving up, the smoothness of the steering wheel, and the overall sleek design of the vehicle stimulate our senses and make us think of ourselves as sexy drivers who command respect on the road. As such, we may find ourselves becoming more attentive to our appearance and behavior behind the wheel as well as seeking out partners who share our enthusiasm for automobiles.

The new car smell has been studied extensively by researchers looking at human arousal and eroticism, but there is still debate over whether it actually contributes much beyond providing novelty value. Some say that humans are simply hardwired to enjoy fresh scents because they signal safety and fertility, while others argue that the psychosexual factors involved play a larger role in shaping our response to them. Regardless of which side you come down on, though, it's clear that new cars hold special appeal both as objects of desire and symbols of status. They offer a way to express our personalities and impress others, even if only briefly before they lose their charm. For those of us who love them, though, keeping the smell intact is crucial; not just for nostalgia's sake but also because it serves as a reminder of why we fell in love with them in the first place.
