Britain's first fast-charging electric buses will be launched on Wednesday.
There are three of them and they are going to transport passengers through Coventry in the city's park and ride scheme.
The buses have been part funded through the government's Green Bus Fund.
The BBC's Business Correspondent, Emma Simpson, has been given a sneak preview of how they work.
