Rolling down your vehicle window to get a breath of fresh air may be unnecessary in your next Nissan. The Japanese automaker just announced the development of its new "Forest AC" air conditioning system, an automotive climate control setup designed to control humidity, aroma, and other ambient factors in addition to the temperature and air cleaning features found with current systems. According to Nissan, the Forest AC is the first automotive system in the world created to make driving more comfortable based on the driver's mental activity. The development of the optimal artificial atmosphere for driving was based on Nissan's studies of how surroundings influence the physiological state and senses of test subjects.
Researchers found that when humans were exposed to certain aromas (e.g., fragrant wood and leaves) combined with ventilation simulating natural breezes, they were alert and focused yet free from unnecessary tension. While there is no word if the scent of freshly baked waffle cones has the same effect, Nissan says we'll see Forest AC on the new Fuga scheduled to debut in Tokyo later this year.
