What refrigerant is used in 2007 ES350?

R134a, standard type.

After doing alot of research, I am going to take the plunge on the 2024 UL ES350. It is clear from everything I have read that the next model (whether is likely late '25 or '26) will not have a naturally aspirated v6 which is really one of the main factors that makes this car as smooth and reliable as it is. And if they stick a more powerful turbo engine in it beyond what is in the new camry, it will likely require premium gas. So added complexity, more operating roughness and premium fuel; not interested. Hybrids are great but power is down from the V6 and they too are 4 cylinders with some inherent roughness although it will probably be well masked. The new ones will have the Version 3 of their safety system but based on the reviews I have read of the new RX, this version of the safety system can be a bit overbearing. Seems like version 2.5 which is in the current Lexus ES if probably as far as I want to go. I am not a great fan of the huge grill on the current vehicle, but that is a fairly minor issue when it comes to getting a car with a super smooth and reliable V6. The current generation is refined, quiet and well built; I don't see alot of things can could wow me on a new generation. Just my 2 cents or should I say 50 thousand+.
