Both diesel cars and light trucks are receiving a
lot of attention in the United States as a near
term strategy to achieve fuel economy and climate
change goals.

The renewed interest in diesel as of late stems
from its potential to improve passenger vehicle
fuel economy. The best diesel passenger vehicles
of today are more efficient on fuel than their
gas counterparts, helping to reduce carbon
emissions by 30 percent or more.

There are some auto makers that are talking about
re-introducing diesel into light duty markets as
a solution for reducing global warming pollution
from both cars and trucks. Another important
reason is that the higher efficiency of diesels
will provide a quick fix for manufacturers who
are struggling to meet federal fuel economy
standards for light trucks.
