The Alliance of Automobile Manufacturers, a trade group representing General Motors Co, Volkswagen AG, Toyota Motor Corp and others, said NHTSA's "report shows continued progress and higher fuel economy across the entire fleet, but it also shows the continued gap between the standards and the market. "The Alliance continues to advocate for increased standards that are attainable and reflect marketplace realities," the lobbying group said in a statement. The Trump administration gave automakers another respite on fuel economy in July, when it cancelled a rule that would have more than doubled penalties for automakers failing to meet fuel efficiency requirements.
