Nissan unveiled an intelligent air-con system which stops unpleasant smells getting inside a vehicle.

The system uses odour sensors on the outside of the car. When the sensors detect an unpleasant aroma, the system automatically closes the intake vents to stop the air getting in.

It can then release a leafy 'forest' smell, created using essential oils, into the car to combat any whiffs that manage to get through.

Once the sensors no longer detect the offensive odour outside, the vents open again to allow fresh air in.

A Nissan spokesman said: 'The system is designed to recreate the refreshing climate, fragrance and natural breezes of relaxing forest settings.

‘It utilises an automatic intake control system, coupled to multiple wide-range, highly sensitive micro-sensors, to prevent the inflow of unpleasant air into the cabin.

‘In addition to a conventional exhaust sensor, the system includes the world's first sensor system for detecting various other odours, such as from animals, from outside the vehicle.

‘It will then start opening or closing the intake vents as needed without constant driver input.’

The system will first feature on the new Nissan Fuga saloon car, which will be released later this year in Japan.

Nissan says it developed the 'Forest AC' system following a joint research study with Professor Kikunori Shinohara of the Tokyo University of Science, Suwa, Japan.
