Hydrogen city car hits 300mpg and 30g/km CO_2

摘要

With politicians and carmakers waxing lyrical about electric vehicles, the squat hydrogen fuel cell car with a top speed of 50mph introduced by start-up Riversimple in June is definitely bucking prevailing trends.rnBut what the Urban lacks in pzazz, it makes up in green credentials. Thanks to its super-light carbon composite body (just 350kg), fuel efficiency reaches an impressive 300mpg. It gives off no exhaust pipe emissions, and, says Riversimple, it's also a lower carbon' car than the all-electric G-Wiz. The carbon emissions resulting from generating the electricity used to produce its hydrogen fuel work out, per kilometre, as half as much as those emitted in producing the power for the G-Wiz (30g/km as opposed to over 60g/km).
