WASHINGTON (Reuters) -An influential consumer organization on Wednesday urged Republican lawmakers to drop a plan to impose a proposed $250 annual fee on electric cars to pay for road repairs.

Consumer Reports, which also tests and rates new vehicles, noted that Republican Senator Bernie Moreno has called for boosting the proposed yearly fee to $500 for EVs and $250 for plug-in hybrids versus the tax and budget bill over the fee in the bill approved by the U.S. House in May. The fees would mean consumers would pay anywhere from three to seven times as much as owners of similar conventional gasoline vehicles in federal gas taxes, Consumer Reports said.
