Gas copy of PAC CAR II:


BYU probably has the PAC CAR book on how to build one; I know the CAD data is available for purchase.

Heh. I went back to to look at it again--I did not watch the video the first time--because I remembered "tricycle/vehicle."

No, not pedal-powered.

Wouldn't a velomobile beat it in every category?

By the way, "Burn and coast." Genius!

these "vehicles" are ridiculous. I could win this competition on a mountain bike with knobby tires. if it can't leave the parking lot it is not a car.

Frank, is it a copy or is it just that they are achieving the same optimized shape as the PAC CAR?

To many questions, there really is only one right answer.

No, they aren't.

They are a wonderful educational opportunity for students- the one project has planning, budgeting and/or fundraising, designing and engineering, learning how to select and fabricate with the chosen materials, testing and development, competition... they have their hands full working on a project of that scope, believe me. The time frame from beginning to completion is rather short.

I worked on student SAE cars and they were one of the highlights of my whole danged college career.

As noted, the folks who did PAC CAR sell the CAD data for the body. This one has the same size and shape, with only the cutlines and windows differing.

Clarification: "up to" 25 mph.

15 mpg "on average" says the person in the video.

My Metro/Firefly is a fuel hog by comparison: ~104 mpg US using burn & coast over a long distance at ~20 mph average. But I got to sit in a comfy seat and listen to the radio while driving. And I had suspension.

Yes, but I think that the driver is cute!

How big was the fuel bottle? Half a liter? Good for a hundred and seventy miles?

I still want to see a distance competition between this and a velomobile.
