GM to stay with R-1234yf

Compiled by MACS Staff

As was reported first yesterday in Automotive News, General Motors says they will continue their plan to use the ozone-friendly refrigerant R-1234yf. Despite safety issues raised by Daimler in August 2012, GM says that their latest testing confirmed previous testing that the refrigerant is safe for use in their vehicles.

GM is currently using R-1234yf in the Cadillac XTS and the European version of the Malibu. In an Automotive News interview a GM engineer said that over the next five years GM will convert most of its North American cars to R-1234yf.

R-1234yf use is not required by the U.S. EPA but vehicle manufacturers who do use it will reap rewards in CAFÉ credits. In the European Union, vehicle manufacturers are required to begin using R-1234yf by January 1, 2013. Currently, Daimler and Volkswagen have declined to comply with the new law.

As always, MACS will be following this story.

If you attend the 2013 MACS Training Event taking place February 7-9, 2013 at the Caribe Royale in Orlando, FL you can be assured R-1234yf will be a major topic of formal presentations and informal  hallway discussions.
