A new fuel economy standards for passenger cars will be released in 2019 and 2021, but the first official data is expected to be released later this year, a US auto industry official said.
The new standards will aim to cut air pollution and improve the quality of life for motorists, the official said, speaking on condition of anonymity because the work is confidential.
Car companies have been lobbying for longer than any other industry for a more stringent fuel economy test, but progress has been slow because there are many technical challenges, including a lack of common standards.
The American Automobile Association, the trade group for U.S. automakers, has long advocated for a mandatory fuel-economy standard that would require all vehicles to be equipped with sensors that measure the energy they use, like those found in electric cars.
But the industry has struggled to find a single standard that will be widely accepted.
One issue is the lack of industry standards for measuring the amount of CO2 emissions from vehicles.
Some countries have made significant strides toward setting the amount and duration of emissions tests, but it is unclear whether such a requirement would be mandatory or voluntary, or whether there would be some kind of incentive for companies to adopt the tests.
In addition, there are concerns that new technology could make it easier to cheat emissions tests.
The US National Highway Traffic Safety Administration, the federal government’s top safety regulator, has been working on developing a standard for air pollution sensors, which would allow automakers to record information about the emissions of a vehicle on a dashboard, a small scale device that measures air pollution.
“This is a critical technology for our economy,” said David White, the executive director of the American Automotive Dealers Association, a trade group.
It is also an important technology for the world.
If it is adopted by all, it would be a huge win,” he said.
However, the US auto lobby has been opposed to air pollution tests for decades.
Even in the US, a federal court in 2009 upheld the ban on air pollution testing, saying it was “intended to protect public health.”
