Highway efficiency climbing from sea level to 2800 feet?

Just tested my truck’s highway efficiency going from sea level up to 2800 feet. Curious if anyone has any data or thoughts on how elevation affects efficiency.


Going uphill at highway speeds can hurt efficiency, but it’s hard to tell without knowing the roundtrip numbers. That said, the truck looks great!

Didn’t track every detail, but I started with 80% charge and reached the summit with about 42%. Got to a Tesla supercharger near my place with 12% left and charged up to 35% before heading to work.

@Mikel
Based on quick math, it looks like you got around 2 miles per kWh on the way back. Might be worth considering a full charge if you’re doing this route in colder weather.

At least you’ll get some of that energy back coasting down.

Is the truck leveled?

Yep, it’s leveled.

How much leveling did you do in the front?

What was the outside temperature? It can make a big impact on your range.

Interested to see if a full charge could handle the trip in snowy conditions!
