- 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.
However, the exact acceleration will not be known until the complete car is taken for its first test drive.
"It's nearly there and the plan is to drive it when the show is over," said Mr Parkin.
The £1.9m project to build the Lifecar, part funded by the UK government, has taken nearly three years.
"The basic concept was to build an entertaining and fun sports car that would act as a showcase for the technology and would deliver 150 miles to the gallon," said Mr Parkin.
"Everything else has tumbled out from that."
