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

[kach22i]

For an open top, open wheel car this is interesting aerodynamically speaking.

Based on a Lotus Elise perhaps?

It seems the wind tunnel smoke should go lower so it shows what's going on with the grill area.

I'm wondering if anyone has characterized the performance of the partial pontoon front fender.



No distortion in that 12ft long free-blown piece of Plexiglas, no sir.

This one is interesting to me because the air curtains are similar to what I'd do on my Superbeetle.

Public Relations shot; repetitive smoke lines are pleasing to the eye, similar rhythm also found in architectural designs (series of columns, windows etc...).

See also music and the other arts.

The messy actually stuff the engineers find useful would not be very pleasing I suspect.

The "hey look they have a problem" in lieu of "hey look isn't that fluid looking" would be counter productive to their intended purpose.

I'm sure that we have seen this before on human powered and gravity racers. Sometimes on the two wheel variety as well if I recall correctly.

I'm picturing one of those colorful CFD images right now, pretty sure I've seen a study on this before.

From 2010, a concept mini van.

The HX1 delivers an estimated 73.5 mpg (U.S.) while offering seating for six adults. It’s plug-in hybrid drivetrain is mated to a 204 horsepower turbo-diesel engine to power the front wheels, while two electric motors drive the rear wheels. Aside from the fancy hybrid tech, a low drag coefficient of just 0.28 also contributes to the slippery look and feel of the HX1.

Read elsewhere that it seats six.

Bucks the current trend of tall cars/crossovers/SUV's.

That reminds me of the Ford Evos



I suspect the Ford door-swings are better.

On the partial fender, I suspect the data was collected by Auto Union in the 1930s:

George, you show a picture of a Tesla Model X.

Here's the lowest drag Model 3:
