General Motors Corp. and DaimlerChrysler AG won a U.S. court ruling that stops a California board from enforcing a requirement for zero-emissions vehicles in the state until the automakers' lawsuit against the rule is decided, according to Bloomberg News. U.S. District Judge Robert Coyle issued a preliminary injunction last week against the Air Resources Board's requirement that starting next year, 10 percent of an automaker's vehicles sold in the state emit no tailpipe pollutants. Only electric vehicles now would meet the California rules, though the board also would give credits toward the goal for lower-emissions models such as gasoline-electric cars and trucks. Automakers contend that consumers don't want electric cars because they are expensive and have limited driving range. California, the largest vehicle market among U.S. states, since 1990 has been tightening its rules with a goal of halting tailpipe emissions.
