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

I suspect that the ReVendo'n could be aerodynamic if converted to electric.

Then all the air breathing or massive drag holes for cooling a V-12 could be closed off.

This idea came about one day while looking at a mold for a Bugatti Veyron kit car knock off. Pretty sure this discussion was in this forum about two years ago.

EDIT: I could be wrong about something - oops.

The closest car I could get C of D numbers on is the Lamborghini Aventador, amazingly it's number is a very low. How low is still debatable.

Source-1: Cd = 0.23

Source-2: Cd = 0.33

Source-3: Cd = 0.35
http://www.svtperformance.com/forums...-the-Aventador

Lamborghini Gallardo LP 560-4
(A) 1.93 m²
(cd) 0.35
(cd × A) = 0.67
at 200km/h
downforce front 4kg
lift rear 37kg

Let's toss out the low and high numbers, that's a decent Cd is you ask me (0.33), not the same exact model but close enough for now.

for trains. Here's the McKeene motorcar

One of these ran on the West Salem/Dallas/Falls City line a few miles from where I grew up, 30 years before I was born. Growing up, my all-time favorite train was this one. It turns out they ran up the Columbia River Gorge, right past Rooster Rock.



arcosine -- That is one long post ....but worth it.

Edit the Second: aerohead has thanked me already but there's more. Hope he sees it.

Just a car guy : the biggest Tempo Matador ever made, an RV by the Mikafa Coachbuilders (Karosserie Minden Karosseriefabrik)

The Tempo Matador had front wheel drive by a 36hp VW flat four:

Fantastic article, I did a college/class room speech on this topic in a public speaking class about 30 years ago.

One of the vehicles mentioned I just had to Google.

I think that photo supports the statement made earlier by someone else that low speed vehicles like tractors are exempt from being aerodynamic as a matter of function.

Boy, 36 HP, I bet that was not a "Get Up And Go'er"...

Yup (spitting out a big load of tobacco juice),that'd be enough power for an electric toothbrush in Dallas.

Pursuing the idea of a Schlorwagen/Inrekor clone for another thread I was reading this: <<Porsche Type 64>> Wherein you find:

Why call it the Type 64? The model number came about because the car was built mainly from design drawings for the Type-64 "record car". Most mechanical parts came from the 38 prototype series. The chassis was heavily reinforced and the engine also reworked to produce around 100 horse power... Its flat-four engine produced 50 bhp and gave a top speed of around 160 km/h (99 mph).

That's on the basis of the original sub-1 liter engine with 21hp. By 1963 Porches came with the Super 90 engine. In the mid-50s when this motorhome was new, big bore kits, Okrasa dual-port heads and roller bearing crankshafts were available for the 1200cc 36hp engine. And Judson superchargers. That rust-out Matador fore-body is from an old truck, not the motorhome.

OTOH this bad boy isn't all that much larger than a camper, no larger than a South African class-C motorhome, and it has an aluminum body.
