ChamPrius!

With that name I found a few others. The few positive comments from Reddit:
"This is actually the car of a physics professor at umass. Hes known for being eccentric. He claims he gains an extra 5mpg on the highway."
Quote:
For anyone that's interested:

This is Champrius, a heavily modded Prius made by Kim Lumbard (you can find him on Instagram at kimlumbard). I've met him in real life (he is one of my mother's friends). That car has a solar panel, refrigerator, bed, and much more.

He recently succeeded in finishing his goal of getting a ticket in all 50 states (Alaska was the last state, we saw him right before he made his way up there).
Can someone clean up this image?

What I learned from one year of Instagram posts from the ChamPrius owner (image heavy)

First of all, I do not understand Instagram. The first time that I heard of it the silly girl said "It is like Facebook, but just pictures!" The result was that it loaded slower than something with more text.

The ChamPrius has burned oil since he bought it, he needed to replace the cat, and he installed an oil catch can to reduce oil burning.

It sounds like his belly pan originally covered the CC, but the mechanic said this would not have caused a problem, burning oil did.

The full name is Champrius Pukonversion because the cat caused a rotting smell and so did the vent hoses on the hybrid battery.

"Coroplast, which is short for corrugated plastic." I never thought about that!

The exhaust tip is connected by a flexible joint, which failed, trapping the heat inside of the belly pan.

He once accidentally left his car running for two days straight.

So, pictures:
He has a heated blanket under his mattress. If he sleeps with the engine off this half-drains his 12v battery:

His side skirts trapped a great amount of debris:

Belly pan:

Side skirts:

He put dryer hose in his side skirts to maintain their shape:

The plexiglas has cracked at least once:

The big hole is supposed to release the heat produced by the catalytic converter. The front flap is the inlet:

Heat failure:

The belly pan trapped debris, too:

His original front side skirts, which made the car quieter, but did not improve fuel economy. He removed them when he realized they floated outward, negating their benefit:

Basjoos style:

Wiper deflectors!:

Closing the wheel gap:

Parking lot hit and run:

That is it! This is the last that I am working on someone else's project! I squared up the informational image, but typed it up below:

This hybrid is named
Champrius
She used to get 40 MPG, but now gets
60+ MPG
The modifications make her more aerodynamic.

The biggest contributors to fuel economy are:
  1. This tail, reducing turbulence on the back
  2. The grill blocking in the front near the radiator
  3. Some belly pans on the underside
  4. The moon disc hubcaps smoothing the wheels
She also has many minor changes like deflectors around the windshield wipers and door handles.

The goal is to achieve triple-diit MPG. Future mods:
  • Finish the belly pans the whole length of the car
  • Put a better nose on, removing the stagnation point
  • Catamaran the wheel wells and tighten the air flow
Feel free to follow the madness: @KimLumbard.

Thanks for all that work, liberating the data.

I think front wheel skirts need to be on a four-bar linkage instead of a top hinge. Then you just add weight to the bottom or bungies to hold them down.

Lol!

EDIT: ... my blackandgreen is way simpler and gets roughly the same FE.

Thanks for posting all that, Xist! You earned that t-shirt.


If he "used to get 40 MPG", I'd like to know more about how fast he typically drives, and the highway/city mix.



I suspect it'd get waaay higher than 60 MPG driven in my typical environment (ie. mostly on the scenic route/back roads with 50 mph / 80 kph limits).
