I’ve been driving on the highway with HDA for over an hour and a half. Started with a full charge, so the guess-o-meter reset.
Honestly, it’s impressive to see this kind of efficiency after driving that long. Still have a couple more hours to go, though.
You’re getting great conditions there – 65mph, HDA on, and 81°F outside.

Yeah, but as soon as you go above 70mph, efficiency really drops.
Of course, if you have charging options along your route, going faster could save time since charging can be faster than what you save by driving slow. But it does cost a bit more.

Why switch between 0 and o like that?

Could be a bot at work here.

Honestly, I always thought driving manually and anticipating traffic would save more energy than HDA. When I tried HDA, it felt like it accelerated pretty aggressively whenever cars changed lanes nearby.
@CalebMiller4
With a clear road, HDA can work pretty efficiently. The trick is to still anticipate traffic – like changing lanes early to avoid getting cut off and adjusting speed for better coasting distance. On long road trips, HDA can be great, but for daily city commuting on the highway, it’s not as efficient unless you don’t care too much about saving energy.
Is it AWD or just RWD?

RWD, lol.
I usually get around 2.8 mi/kWh going 70-75mph in my I5N in N mode. Switching to Eco mode, it bumps up to about 3.0-3.2 mi/kWh at the same speed.
Honestly, not a big enough difference for me to give up the 541hp feel of N mode.
But yeah, 4.1 mi/kWh is insane .
Do you always take photos going 65 on the highway? Hope you’re not posting while driving too.

They’ve got HDA on, with nobody in front of them – a quick photo wouldn’t be a big deal.
Gonna hold back my thoughts until the person who posted this shares how far they’ve driven. I can drive about 1.5 miles downhill from my place to the highway, hit 65mph, and show 8 mi/kWh or better.
From what I know, the gauge resets after charging. If they’re at 72% SOC now, they probably started from an 80% charge.
@Morgan
With their speed, 4.1 mi/kWh is definitely possible. I just set my car to HDA at the speed limit, which is around 65-70mph in my state. In warm weather, I can get over 4 mi/kWh easily. Did a drive from Charlotte to the Outer Banks in Summer 2023 and managed 348 miles (4.49 mi/kWh), with AC on since it was over 90°F outside.
Driving below the speed limit will always give you better efficiency. Try following a semi-truck for even more savings.

I tried drafting a semi on the freeway for an hour once, and I was shocked by how much more efficient it was.
