Which refrigerants are currently used in new vehicles?

• A. R410A
• B. R1234YF and R134A
• C. R22
• D. R12

Answer: (B)

Modern automotive A/C uses refrigerants chosen to limit environmental impact. The refrigerants currently found in new vehicles are R1234YF and, in some models, R134A. R1234YF is the newer option with much lower global warming potential and has been widely adopted in newer cars. Some new vehicles still use R134A, depending on the model or production timeline. Older refrigerants like R12 and R22 have been phased out of new cars due to ozone-depletion concerns, and R410A is not standard in automotive systems (it's typical in residential/commercial air conditioning). So, the best answer reflects that new vehicles employ R1234YF and, in some cases, R134A.
