Nissan has created what it calls 'the scent of the future', representing what Planet Earth might smell like in an imagined world where everyone drove zero-emissions vehicles.
By teaming up with master perfumer and Aroma Academy scientist Dr George Dodd, the firm has created its 'aromatic blueprint' for the future.
Dr Dodd, reportedly inspired by long walks in the Scottish Highlands, has created an in-car fragrance that he says is proven to inspire 'a positive sense of well-being' in people who smell it.
It uses essences taken from cut green grass, myrtle oil, natural orange and the ineffable "light as air" molecule, which is perhaps the most mysterious element of the perfumer's business.
Dr Dodd grew up downwind of the Guinness brewery in Dublin, and credits this with the development of his nasal expertise at an early age.
Nissan has recruited him to create a light-hearted gift for electric car fans. The fragrance will be infused into in-car air-fresheners and given away.
Nissan said of the project: "The innovative yet light-hearted gift celebrates the pioneering steps Nissan is taking towards an emission-free future and reminds recipients of what they are contributing to when driving their LEAF."
Dr Dodd commented: "We are very proud to have been asked to create such an abstract and innovative scent with Nissan. When Nissan came to me and asked me to create a scent of the future it was quite a scary thought, but it was a challenge I thoroughly enjoyed.
"This bespoke, futuristic aroma embodies a palate of smell sensations that have never before existed together and represents a future Nissan is helping us drive towards."
