Fuel Saving Tips
Hybrids like the prius have to run the gasoline engine at startup to warm up the catalytic converter. But if your commute starts with a junction onto a busy road, your gasoline engine will be running for several minutes to do this while you wait. Instead, switch to EV mode at startup, and keep in EV mode until you finally get out into the traffic. Now you need your gasoline engine to get up to speed, so it can finally warm up the cat converter now.
