Volkswagen said that in October it will propose a fix to the diesel cars it rigged with manipulative software to fool regulators into believing the vehicles were corresponding to emissions regulations.

The automaker said that it will begin notifying owners of the 11 million vehicles affected by the software, which causes the cars to emit harmful pollutants at rates of up to 40 times U.S. standards. But there is still no information on how long it expects the fix to take or whether it plans to offer compensation to vehicle owners.

It's unclear how the fix will affect the fuel economy and general performance of the cars involved in the scandal, though some industry experts expect the cars' fuel economy ratings to fall. 

In the U.S., the deceptive software affects the four-cylinder diesel versions of the 2009-15 Jetta TDI, the 2009-14 Jetta SportWagen TDI, the 2010-15 Golf TDI, the 2012-15Beetle TDI, the 2012-15 Beetle Convertible TDI and the 2012-15 Passat TDI.
