Chrysler adopting R1234YF

by David Zatz on

Ignoring former parent Daimler’s objections to a new refrigerant, Chrysler plans to start building new vehicles with “R1234YF” in the air conditioning system. R1234YF has a minimal “greenhouse effect” when compared with the current R134a, and has been mandated by the European Union.

At this time, R1234YF is scheduled to be used in the 300/300C, Challenger, and Charger starting in late October. Allpar does not know whether the refrigerant will be used in export-bound cars (e.g. Lancia Thema) or domestics as well, but it’s likely that it will be used universally, since it requires different compressors, hoses, and other components.

Daimler, AG claims that R1234YF is a fire hazard in certain collisions; their internal tests could not be replicated by numerous other groups, including the Society of Automotive Engineers.
