As we drive around in our cars, it is largely our perception that determines the driving experience: The road manners of the car, the sound of the engine, the texture of the touchpoints, the functioning of the controls, the way the interior looks are all different from vehicle to vehicle and provide the "feel" of the car.

Those elements, which luxury carmakers tune towards their brand identity, encompass three senses: Sight, sound and touch. Lincoln's designers are trying something new and expanding into a fourth sense, smell. "Lincoln engineers and designers have studied how the senses can impact mood, as well as physical and mental wellbeing, and how that translates into a relaxing experience for the client," the company writes. "The sense of smell is of special interest, as scents and the power of aromatherapy can affect overall mood."

"Scent is one of the five senses that has one of the strongest connections to not only memory, but emotion and can play a significant role in creating an experience for our clients on the road," said Flore Tramblin, visualization designer for Lincoln.

To that end, they've rolled out these scent cartridges created by perfumiers:

Mystic Forest: an earthy blend cedarwood, rich notes of patchouli, amber and yuzu citrus

Ozonic Azure: a crisp fusion of aromatic patchouli and traces of freesia and spice

Violet Cashmere: a harmonization of rich violet, grapefruit, and golden citrus

Cloud Balsam: an invigorating blend of lush pine needles, oak moss, crushed tonka and vanilla beans

Serene Seashore: hints of juicy melon, fragrant lily, musk and bright lemon combine in this radiant mixture

Twilight Embers: An enchanting suite of patchouli, floral jasmine, fresh apple, and deep leather undertones

Sunlight Retreat: Sandalwood and rose highlight this union and are accented by crisp red fruit and balsamic notes

The cartridges are inserted into a panel under the lid of the center armrest.

The driver selects the scent via the center touchscreen, and the scent then diffuses through the center console—independently of the heating and cooling vents, interestingly. There are three different levels of dispersion and "separate profiles can also be created to customize how the scent is dispersed throughout the drive," the company writes.

The Digital Scent feature is rolling out in the 2024 Nautilus.
