Hyundai has revealed that the Nexo has cleaned more than 900kg (918.75kg) of air on London roads during Clean Driving Month. That is the same amount of air that one adult breathes in 60 days or 1,455 adults breathe in one hour. The brand new next generation hydrogen fuel cell electric vehicle took to the streets of London across 31 days culminating in a weekend where the public had the opportunity to get behind the wheel.

With a total of 560km driven overall, the car - which actually cleans the air as it drives - was driven along London's dirtiest driving route throughout the month. The route was mapped in partnership with University College London who reviewed open source data from a King's College London pollution study to look at NO₂ levels and Particulate Matter (PM) levels with particularly congested roads including Marylebone Road and Park Lane.

The Nexo, which is available next year in Europe and emits nothing but water, has an advanced air purification system, which filters 99.9% of very fine dust (PM2.5), which is then retained in the Nexo and not expelled back into the air. As well as being a zero-emissions vehicle, the Nexo also features an adjustable regenerative braking system that recuperates additional energy when possible and significantly reduces other pollutants like brake dust.
