Hey Dave,
I just got a new Hyundai Ioniq, and I’m looking forward to the fuel economy savings.
I’ve noticed that the way that I drive affects how often it’s running off the battery vs. gas (although I guess that’s obvious).
Are there any general driving habits I should try to develop to improve the gas mileage?
Thanks!Yes! Driving habit #1: Use the bar graph on the left side of the instrument panel to try to optimize the amount of regenerative braking and minimize the friction braking. The harder you press on the brake pedal, the more blue bars you light up, but any braking beyond max # of bars (in the down direction) is friction and represents energy you don’t get to put into the batteries. This will mean look ahead and plan you braking when you can.
tip#2: You will notice that in normal driving, the car goes into EV mode whenever you lift off the gas pedal or get into very light loads. When you have to accelerate, the lighter you press on the gas pedal the longer you will stay in pure EV mode. The point that the car transitions between engine on and off is very dependent on the state of charge of the battery pack (gauge on the right). While you are getting used to the car, use display screen that shows the hybrid system diagram so you can understand what mode you are in in different driving situations.
tip #3: Minimize use of AC. Even though the Ioniq has electric AC compressor, it is still a major energy draw and can cut your fuel economy by more than 10%. In all but warm weather (when you really need AC), stay out of automatic climate control and choose to turn the AC off, because in automatic mode, the AC compressor runs more than it really needs to. Also in cold weather try disabling the automatic defrosting mode, because that also turns on the AC compressor. I do find the automatic defrost useful in warm rainy weather.
tip #4: Do not warm up the car before driving (like with remote start). Just get in and drive. Modern engines do not need more than about 10 seconds of warm-up before you start driving. Idling is the slowest and least efficient way to warm up the engine.Enjoy your Ioniq!
