WASHINGTON (AP) -- Leaders of a House committee are requesting more details and documents from Volkswagen after federal regulators said the car maker cheated a second time on emissions tests.
The Environmental Protection said this week that VW programmed about 10,000 cars with larger diesel engines to emit fewer pollutants during tests than in real-world driving.
The charges follow VW's admission in September that it rigged emissions tests for four-cylinder diesel engines on 11 million cars worldwide, including almost 500,000 in the United States.
Leaders of the House Energy and Commerce Committee sent a letter Tuesday to Volkswagen's U.S. CEO, Michael Horn, requesting additional information about so-called defeat devices designed to skirt emissions controls.
The bipartisan letter set a Nov. 16 deadline for Horn to respond.
