Gravity 75 mph Range

[ilyabu]

All I will say is my 2023 quad R1S routinely gets that 2.4 mi/kwh. I will be disappointed if the Gravity doesn’t beat that as one of the reasons I want it is for range and efficiency. Granted, that’s not a top three reason, but it’s important.

All these other numbers being quoted confuse me. Everyone drives differently.

Porsche EVs are so overpriced they’ve never been something I’ve seriously considered. My opinion, of course.

so far I'm getting about 2.7 on the Gravity

2.7mi/kWh equates to (roughly) 330 mile range, about 74% of the claimed range (450mi). These metrics are similar to what the Air achieved. But we need more data and controlled efficiency/range tests to pin it down for the Gravity.

note that I have the DE with the largest (22/23") wheels. I will be doing some longer drives in it next week so expect to get more data points.

That would be great! Please share your data with us. Keep a log on your speeds as well. Speed, elevation change, temperature, and AC usage are key modulating factors.

Yes, wheel size matters. Need to derate the achievable range accordingly.

I am also getting 2.7 pretty consistently, with a DE and mid-size wheels.

2025 Rivian R1T Tri-Max data point for comparison. This is at slightly above sea level, certainly not at OOS elevations.

It will be interesting to see how much better the smaller wheel GGT models do. Although I am surprised you are not getting better efficiency even with those wheels.

As others have pointed out, so many factors impact efficiency. But speed is especially important. Is 2.7 really the 75-mph efficiency, or is it possible you are going faster? Spurts well above 80 will have a significant impact. In my data, I set the cruise for 79 mph. The average is lower due to traffic. In this drive I never exceeded 79 mph.

The DE large wheels I believe is EPA at 370 miles.

I have a GDE with the smallest wheels and am seeing around 3.2-3.3mi/kWh over the first 300 miles or so.

What kind of driving? Speed? City? Hwy?
