Good point about Wind Resistance. I didn't think of that!
Combined with non-use of the brakes because of regen-braking, that makes those hole-less wheels look a hole not better.
To my amazement the best seats that I've owned in any car -- and it's not even close -- were in a 1998 Chevy Prizm. Long road trip? No problem!
Slate's new Seat Designer should find a junkyard '98 Prizm and use those seats as a template because Chevrolet (Toyota?) absolutely nailed it. That's...
Big time.
Among all of the Battery Buzzkills I've looked into, highway-speed driving is the biggest surprise.
As speed doubles, the power needed to overcome drag increases by a factor of eight.
Driving at high speeds affects EV range waaay more than I expected.
The shape of the Slate Truck...
It's more difference than you'd expect, yes.
[Edit: and for good reason! Miscalculation.]
Another way of looking at it:
If you can get 40 miles of range on an overnight 110v charge of a Standard battery, the same charge would only get you 35.7 miles if you have an Extended battery...
Maybe I should have chosen a better word.
Slate is claiming, by publishing those numbers, that the same energy that gets you 100 miles with a Standard battery only gets you 89.3 miles if you have an Extended battery.
I wouldn't call that negligible.
[Edit: Calculation error spotted by @Driven5. Now re-calculated here.]
So I crunched some numbers....
The standard battery has a capacity of 52.7 kWh and the extended battery has a capacity of 84.3 kWh. The ranges are 150 miles and 240 miles respectively.
240 miles on 84.2 kWh is 2.85 miles...
My only reasons for buyer's remorse would be a major design or production flaw. Or maybe customer-predatory subscription features (*fox-growl sound*).
Other than that I'll be golden if the Truck performs as advertised.
I don't have much of an opinion about Projected Pricing because I realize that market equilibrium price will be determined by basic economic principles (cross elasticity of demand, price elasticity of demand, really just supply and demand forces in general) in a future market that doesn't exist yet.
And they almost certainly limit charging so 100% indicated is really less than 100%.
I forgot about that. I learned it from a guy who sells lithium golf cart batteries. FWIW, he made 100% on the controller actually be 97%.
Good catch!
3.2-2.85=0.35 kWh in lost efficiency by hauling the extra weight of the extended battery everywhere you go. Could that be right?
Edit:" What does that translate to in dollars-per-mile?" would be the question for determining cost-of-ownership of the bigger battery.
