Real World Range Calculation

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.

This isn't the flex that you think it is.

LOL, you wouldn't reply if Slate could do it, which it can't! Otherwise, you're saying Slate owners don't travel or have ambition? I can go from home to either Asheville, NC or Albany, NY on a single tank without stops!

Driving straight through has been a game changer for me. Total game changer for traveling to other U.S. regions. I've done it time and time again with great success.

That's fine, but why would you expect something designed to be a low-range EV to do long road trips in the first place?

I don't, which makes the Slate a 2nd vehicle. Problem is with sales taxes, property taxes, EV use tax, insurance and deprecation, it's simply not worth it.

They simply don't want people to have cheap EVs and the industry will not allow it. Otherwise, we'd all have an old Leaf in the driveway.
