The second photo was before the tape was removed from the canopy and the stickers applied. I ran out of time to fabricate a fairing for both the rear axle and the steering arms, but otherwise I think it is relatively aerodynamically clean.

Just took a few more photos of the car in my classroom (i'm a high school teacher) which show off the side profile a little better.






Wooly, do you have any pics with the shell off? I'm curious about the frame, steering, and brakes.

Took a while, but downloaded great! This is the only link that showed exactly what happened to me in a panic stop on my Pod (tadpole) velomobile- front hit the road, back flew up several feet. Great pictures!

Some 3-wheel car plans, some 4-wheel cars, some about aerodynamics, some electrics, ending with velomobiles. Like looking throughout time! Excellent for 3-wheel fanatics like me!

let engineers design cars!, and stylists decide what color the seats will be.
Because real cars have other requirements, like carrying 4-5 people, having an engine, and being safe

I like this shape- but it obviously will not carry more than 1, and only has 1 (human) engine. It had safety in mind- note the neat roll bar!
