The U.S. National Highway Traffic Safety Administration said it will delay until 2018 a planned jump in fines for automakers who fail to meet fuel efficiency requirements in response to concerns from the sector over their impact. Two major auto trade associations representing carmakers including General Motors Co, Toyota Motor Corp and Volkswagen AG had urged U.S. regulators to reconsider plans to more than double fines for failing to meet fuel efficiency requirements, saying the move could have boosted industry compliance costs by $1 billion annually. In 2015, Congress ordered federal agencies to adjust civil penalties to account for inflation and, in response, NHTSA proposed to raise fines to $14 from $5.50 for each 0.1 mile per gallon each vehicle is below required standards.
