A "zero-emission" sports car with a top speed of nearly 100mph is set to be unveiled at the Geneva Motor Show.
The hydrogen-powered Lifecar, based on the design of the Morgan Aero-8 roadster, produces little noise and only water vapour from its exhaust.
The lightweight model packs advanced fuel cells and an energy storage system that gives the car a range of 250 miles (400km) per tank of hydrogen.
It has been developed by a consortium of UK companies and universities.
"Figures suggest the car should be capable of doing 0-60 [miles per hour] in about seven seconds," Matthew Parkin of classic sports car manufacturer Morgan told BBC News.
