The Bio-Bug has been converted by UK engineers to run on methane gas.
Excrement flushed down the loos (toilets) of just 70 homes is enough to drive it 10,000 miles - a year's average motoring.
The two-litre VW Beetle convertible is said to be the first gas-powered car that does not suffer reduced performance.
Mohammed Saddiq of Bristol-based sustainable energy firm GENeco, which developed the prototype, says it will pave the way for a green motoring revolution.
He boasts that it drives like a conventional car and will "blow away" electric models.
I don't want to be following that car...
Just an observation...
