Which refrigerants are currently used in new vehicles?

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

Answer: (C)

The main idea here is understanding which refrigerants automotive air conditioning systems use today due to environmental rules and industry changes. Older refrigerants have been phased out because of ozone depletion or high greenhouse impact, and the industry has moved toward lower-GWP options. Currently, new vehicles use refrigerants that include R1234YF, a low-GWP option adopted to replace higher-impact substances, and R134A, which is still used in some new models as part of the ongoing transition in certain regions. R12 and R22 are legacy substances no longer used in new cars, and R410A is not used in automotive systems (it’s common in some home air conditioners). So the combination of R1234YF and R134A reflects the real-world mix seen in new vehicles today.
