Who, What, Why: What's the point of scented cars?
Car manufacturers are dabbling with fragrance systems. Just what is the point of scenting a car?
Get into a minicab and it's often the first thing to assail the senses - powerful air freshener diffusing silently from a plastic tree attached to the mirror.
Some car-makers are now taking things into their own hands. Peugeot offers portable perfume diffusers. General Motors is experimenting with built-in fragrances. The Mercedes S-Class already offers a "perfuming system" as an optional extra costing £360 ($607). Its new C-Class will follow suit on its release in June.
Smell is one of the last frontiers left for car-makers. The MP3 player is there, dashboards are tactile, and no-one much cares about what's under the bonnet anymore, says motoring journalist Quentin Willson. "In the past you could put stripes on the side of your mini. Now you can personalise the interior with a smell." Aromas might help with alertness. But's an extra designed to make money, he suspects.
