The Difference Between Permobil's C-300 And 500 Power Chairs: A Lesson In Technology And Transportation


Before I begin on my latest blog, I would like to, first of all, take 

the time to give a shout-out to a few people: First, my dad, who is 

the owner of Westside Collision in Lancaster, California. For those 

of you who are unfamiliar with the Antelope Valley, Westside 

Collision not only does a detailed job on your vehicle's repair, but 

the people who own the place, including my own father, Sal, are car 

people who know the game even better than Earl Scheib, Maaco or 

any other major, auto repair brand. So the next time you have a 

scratch on your Tesla or Permobil, make sure to give Westside 

Collision a ring!

Second, I would like to take a moment to give a shout-out to Paul 

Huizenga, Mike Alexander and the rest of the crew at Power Auto 

Media in Murrieta, California. Because without their automotive 

know-how, a blog like this one would have never happened in the 

first place. So for everything horsepower online, I strongly endorse 

Power Auto Media and the webzine titles that they cover!



My third and final shout-out will be going to Permobil, and I'm 

happy to say that I and a lot of other disabled people in Los 

Angeles are proud owners of Permobil power chairs. For those of 

you who are unfamiliar with the brand, Permobil's central, North 

American office is in Tennessee, but the company is originally from 

Sweden, and for myself, I find their products to be the best in this 

market, so make sure to check out Permobil when you can!



With that, the bottom line with any power chair is that all of us are 

looking at that market in totally the wrong ways. Why?

Because for the last 40 years, we’ve been saying things like, “Oh, 

that’s way too dangerous!” Or even better, “You don’t need to go 

that fast in your wheelchair!” I can’t really speak for my 

community, but as for myself as a "car person,” I can tell you 100% 

for sure, that sometimes you just have to go fast, and as much as a 

lot of us in this community would just HATE to admit it, sometimes 

you really do just have to put-out as much “horsepower” as 

humanly possible! 




So, when you take the language of automotive and translate it to 

something like a power chair, Permobil or otherwise, you actually 

are able to put together sort of a "performance stats" list, and the 

following numbers show exactly how these "stats" boil-down:


1/4 throttle=2.4-3.0 MPH

1/2 throttle=4.3-4.7 MPH

Full throttle=5.0-5.1 MPH


So the way that the "power chair equation" breaks-down, is that 

each unit should be traveling at variable running speeds, multiplied 

by various workloads and variable terrain, but over variable 

distances.


That was the hypothesis, but the way that the actual running 

dynamic of the Permobil C-300 broke-down was Vrpm * Vwl * Vt / 

FD. In other words, the chair ran under variable running speeds 

multiplied by variable workloads and over various forms of terrain, 

but only over fixed distances.



So if anyone, disabled or not, were to try to make an argument 

about why the physically-challenged community is majorly 

screwed, then that argument would not boil-down to General 

Motors or Chrysler; the hypothesis would have to dial 

itself back to the one that we've just established regarding 

sustainability!
