My new car has a dial to select Eco, Normal, or Sport mode. I can clearly feel the difference in acceleration when I change modes, and see the difference in the mpg, but I know nothing about engines and was wondering what the modes are actually doing. Camry Hyrbid if that matters.

They can do various things, but probably the main thing they do is change the shift points for the transmission. There isn’t an exact RPM or speed that shifting gears has to occur at, there’s a small range of them. “Sport” will usually wait until a high RPM is reached before shifting up , and “eco” will usually shift up at a lower RPM.
