Research and development of cleaner and more efficient
vehicle technologies has been ongoing for the past few
decades. Much of this research started in response to
the oil shocks of the 1970s which triggered concerns
about rising fuel costs and growing dependence on
imported fuel. The urgency of those concerns was lost as
fuel prices declined in the 1980s. At the same time,
however, rising concerns about vehicle contributions to
air pollutiona nd global climate change added a new
dimension to the issue.
