I have had my RX350h for about 2 weeks. I have kept it in normal driving mode. Does anyone in the forum use eco mode? Is fuel economy that much better in eco? I think in eco mode, the car cuts back on A/C use so in hot weather it may not be a good idea? I can't see using sport mode. Has anyone configured a "custom mode" they like?

 

All personal preferences. I suggest you try them all to decide which is best for your driving habits and expectations.
