Interesting Aerodynamic Cars (Mike Vetter's ETV, also Avion)

[serialk11r]

I went to the Blackhawk Museum a few days ago and snapped these pictures of the Alfa Romeo BATs

some_other_dave -- Isn't it? You know what they say about confirmation from a 2nd source. It may have to do with the post-Colani changes in the design.

I think the Trev has been seen here on EM, but not in this thread:






Picasa Web Albums - Team Trev

It weighs under 800 pounds, and goes up to 155 miles on a charge, and seats two people in tandem.

Another interesting aerodynamic car that has been mentioned on EM, but not in this thread - the Urbee:



The Urbee has (at least) two very interesting features: rear wheel steering (hence no need to hinge the front wheel skirts) and a "3D printed" shell:

Sharing a very narrow aero-efficient, Lumeneo Smera. The distinction; the narrow, tall configuration and high driver position/vision is still very stable in dynamic handling because of it's tilt lean capability.

Now imagine if they lowered the H-point, skirted the front wheels and fully boat-tailed it!

[NeilBlanchard]

By 'H-point' do you mean high point? Smooth front wheels would be a good thing, and my guess is that slightly convex sides would be better than the slightly concave sides. Fully skirted wheels would also lower the consumption; but frankly it is already pretty impressive!

I've asked what capacity the Trev is, but they mention a 3-4 hour charge and that seems to to indicate 8-12kWh? So 155 mile range means it is already (well?) under 100Wh/mile which puts it into pretty lofty company of the Edison2 eVLC, the early Aptera Typ 1's, and the Bochum University SolarWorld GT.car - which was also driven around the world.

The caption to that first picture is along the lines of: "when a 2 year old can push your car, you know it is light enough".

H point is Human point, design jargon for where your butt goes. Meaning, if you sat lower and more reclined it would have a smaller frontal area.

I'll have to go back and carefully read their build thread

"Hip" point.
