CAPITOL HILL (AP) - Dozens of auto dealers and executives have been courting undecided senators on Capitol Hill.
They want the senators to oppose an energy plan that would raise fuel efficiency standards to a degree they say would hurt their businesses.
The auto industry is trying to win support for an alternative that would seek more moderate increases than what the current bill would require.
Under the current plan, the fleetwide average would have to meet 35 miles-per-gallon for cars and trucks by 2020, an increase of about ten miles-per-gallon from current levels.
Backers of the plan contend the auto industry is simply rehashing old arguments against increased gas mileage requirements.
The Senate is expected to take a key vote on fuel efficiency standards Wednesday.
