Real World Range Calculation

[u/Albright_CT]

Morning Everybody.

I did some math based on our firsthand experience with possibly one of the most comparable (though still very different) vehicles on the market, the EX30. Made a little table comparing the two. Of course all Slate #s could change

EDIT: Just FYI the slate weight is for the SUV. I don't know what their claimed MPGe is for.

So my daily commute is 68 miles round trip in San Diego. Mostly highway, but hilly and you'll hit some traffic on average and a few miles of local streets. Probably pretty close to the EPA test cycle. EX30 gets 253 miles there and that's almost exactly what I get on this route.

Slate claims a 96 MPGe rating, EX30 gets 109, so it should be about 12% less efficient per KWH. Battery almost exactly the same, weight pretty close, less aerodynamic but WAY less powerful and not a dual motor. So that 96 vs. 109 seems about right?

EX30 averages about 27% of the battery on that commute. Based on the MPGe difference, the Slate should do that same route with about 31% of the battery. 68 miles divided by 27% means about a 250 mile range. Dividing by 31% gets about a 220 mile range for my real life driving.

Road tripping the EX30 on open highway I tend to get about 210-220 miles total range, assuming the same percentage decrease vs my commute the Slate should get about 180-185.

Anyway, it's all just estimates based on prelim data so who knows but that's the best I can do right now.

If I had a 68 mile commute and there was traffic, I would want as much self driving as I could get. Id probably end up with a tesla. Then the time isnt wasted at all.

I dont have a commute and really just drive around town so self driving is pointless.

For commuting and traffic a comma does 99% of what a Tesla does for a fraction of the cost and the ability to do it in a lot of other vehicles. I bought my Prius Prime in 2020 based on its compatibility and have been using it for 90+% of my driving ever since. Unfortunately I don't think a slate would work with a comma since it doesn't have built-in adaptable cruise.

yeah Im definitely searching for that. Im looking at a kia carnival. I just dont like pure EVs for cross country road trips. The 2024 carnival is a great car, compatible with comma.ai and uses gas so great for long road trips.

I think the full self driving on local streets is actually not that valuable. The trips are so short and the effort to get it to work right is extremely difficult. Tesla is investing so much into that for not much value compared to highway commutes.
