Any real limit to running REX?

It’s an app available on Apple

The mi3 app is iOS-only. The Android-only "electrified" app has similar functionality.

Just of interest what is im3 rex runtime readings all of your i3 rex's? We have a 2016 with 104K Km (65K Mi) on the clock and the rex has done 11k km (6.8k mi) on the clock. does BMW have a basic expected runtime on the rex? What's the highest anyone has reported on their Rex?

I've driven for 600+ miles in one day with 550 miles of it on the rex, I added an extra fuel tank so my rex range is roughly 250 miles.

I did need to stop for gas, but other than that it's gone just fine. It keeps up pretty well as long as you're not going 70+ the entire time. I would turn it on at 75% and leave it until I was within 50 miles of home and use the battery for the last bit of my trip.

You can drive on the rex so long as you have fuel.

Can you give us details on your extra fuel tank?

People install tanks in the frunk. Done right, they don't throw codes but require some pretty sophisticated mods with proper venting, pumps, hose etc. There's also a contingent that just puts a fuel can in the frunk.

That said, you will get a huge reaction from posters here. Most say "frunk is a crumple zone, you are asking for a fire" and other say, "nah, no problem." I'm in the "not worth the risk" category.

This dude showed that if the gas station is on the exit ramp (or you hit a green light), from leaving highway to re-entering highway after fill-up is two minutes. And he wasn't trying for a NASCAR or Formula One stop, he just kinda sauntered.
