High Regen vs Low Regen on Road Trip

[Electrified Outdoors]

You get better efficiency driving so regen doesn't have to activate. (The exception being extremely long descents which don't exist in my area) Rivian doesn't blend regen in on the brake pedal though, so if you are touching the brake pedal, you're reducing your efficiency.

This! You don't get all the energy back on regen that you expended to get moving at the speed before regen was engaged.

It will vary based on where you are driving. Also, having it in high on long descents may result in regen being reduced quicker so depending on the decent you may capture more energy in standard or low settings.

It's the same as driving an ICE ....avoid using the brakes except....

You want to avoid slowing down period but if you have to slow down prefer regen over friction brakes where safe, reasonable, and possible.

I prefer high regen at all times because it gives me max slowing power when I need it. Even in high regen if your experienced you don't go into regen unless you want to slow down.

I did a trip from South Florida to Orlando (220+ miles) back in May with STD regen on (2024 R1T PDM STD+), using ACC and Driver+ for a few parts of the trip at 75-85 mph My efficiency was ~2.20 mi/kWh. I did the same trip a few days back but in High regen. A similar type of driving and I got ~2.38 mi/kWh.

To me, as I usually drive on ACC at ~80 mph and then slow down to 65-70 mph if I encounter a slow car or truck, the amount of energy captured was higher on High and thus better efficiency (I noticed the regen bar going further in high compared to STD)

However, what others have said makes sense: Driving behavior, ACC-drive+ on/off, type of road, and traffic, could give you different results.

he turns off his Regen when on a long drive and gets more mileage.
