New Nissans will keep you looking young

The forthcoming Nissan Leaf will feature an air conditioning system that moisturises the skin. The technology blows out air enriched with vitamin C, which, according to Nissan, keeps skin moisturised.

The in-car skincare system is one of a variety of safety and convenience innovations that will soon appear in new Nissans. The company calls it a Health and Well-Being concept.

As well as spraying vitamin C into the cabin, the new air conditioning system will detect bad odours and neutralise them, as well as reducing bacteria so the atmosphere within the car is fresher than the outside.

Seat technology that improves blood circulation is also on the cards, utilising NASA research to reduce back pain during long drives. Known as the Comfortable Captain Seat, it supports the legs to avoid swelling and spreads body weight.

The seat heaters warm the driver's legs and backside first, before moving onto the back. Nissan says this shortens the time it takes to feel warm and is therefore more comfortable.

There's also a system on the cards that could prevent pedestrian impacts, which uses cameras to sense people near the car and, if necessary, apply the brakes automatically. It will sound an audible warning, too.

"The emotional aspect of a car has become increasingly important," said Nissan engineer Kenichi Tanaka.

With that in mind, a 'friendly' speedometer that stores important dates - birthdays and anniversaries - will remind drivers to pick up presents while they're out and about.
