2013 Cadillac XTS First to Use Next-Generation A/C Refrigerant

Cadillac XTS is being used to debut the latest technologies GM has to offer. One more is the first use in the US market of R-1234yf refrigerant. Mandated in Europe since January 2011, the XTS will be the first US product to make the switch. XTSProdR-1234yf will slowly replace R-134a (which became standard in cars in 1994) in automotive applications. The reason for this change is to reduce the 'global warming potential' vs the current substance. In fact, the new chemical has a GWP number 335 times less than R-134a. In addition to the XTS, Cadillac will also equip the new ATS with R-1234yf when it goes on sale in the summer. Source: Green Car Reports
