What is the best driving mode and battery cooling for long highway trips?

Tenss10 · Feb 19, 2025

With Eco, B, and eStep modes available, alone or combined, which one gives the best balance of comfort and efficiency for a 6-hour highway drive at 62-68 mph in 27°C weather? Also, does using A/C to cool the battery help with fast charging, and is the battery heater even necessary in these temps?

Eco mode is the best for what you need. You have comfort and efficiency.
Battery heater isn’t needed at 27°C, and A/C cooling helps with fast charging if you just leave it on the highest setting.
Cruise control works fine unless you have lots of hills.

Thanks, I’ll stick with Eco for the drive. Good to know about the A/C for fast charging. I’ll keep cruise control on unless the terrain gets tricky.

The car's automatic battery cooling system should be left at the highest setting. Battery heating is only needed below roughly 15°C. I find normal mode and cruise control to be the most effective. Mode changes don't signifcantly affect cruise control on flat roads, but AWD systems might be an exception

For a 6-hour highway drive at those speeds, I'd say Eco mode is your best bet for a good balance of comfort and efficiency. It’ll help conserve energy while keeping things smooth. As for the A/C cooling the battery, it can help with fast charging, but it’s usually not needed unless you're pushing it hard. In 27°C, you probably don’t need the battery heater either, it’s more useful in colder temps

Battery heater really only heats the pack to about 8 or 9 C. Thus you can use it pretty freely because it just shuts itself off after a while. In my own experience, my pack will run about 5-7 C over ambient temp so you can see, much above 0 C, the battery heater is probably moot. I’m still going to use it up to about 5 though, just to be safe.
