EPA Vows Tighter Emission Testing, More Spot-Checks
The U.S. Environmental Protection Agency has advised carmakers it may subject their vehicles to new and unspecified tests to help determine if the vehicles have been rigged to cheat the normal certification process.

The U.S. Environmental Protection Agency has advised carmakers it may subject their vehicles to new and unspecified tests to help determine if the vehicles have been rigged to cheat the normal certification process.
"We're upping our game," Christopher Grundler, who heads EPA's Office of Transportation and Air Quality, tells reporters. He declares carmakers "don't need to know" exactly what additional tests the agency has in mind.
The tests also may involve spot-checks of tailpipe emissions from vehicles already on the road, according to the agency. EPA notes the expanded testing may add time to the procedure for approving vehicles for sale in the U.S.
EPA's clampdown on emissions is a result of its discovery that Volkswagen AG sold some 482,000 diesel-powered cars in the U.S. that contained secret software to switch emission controls on and off depending upon whether the vehicle was being tested. VW concedes it installed the same software in about 10.5 million other diesels sold throughout the world.
