Phil -- I just Googled "Honda Dream-2 solar racer" and got motorcycles and ... the usual Internet noise... Any images you can point to?

[NeilBlanchard]

Thanks Phil. The consensus of a best case Cd of 0.1 for a 4 wheeled road going car seems to be gathering...

Try:

"honda dream" -motorcycle +solar 1996

as a search term... provides some reasonably good results... though still not much.

The Dream II, at 6m long, 2m wide, 1.1m tall at the center, and 170kg:


There are a very small number of solar cars with lower Cd, and you could picture increasing their wheel count to 4 without too much drag, but I'll agree that we have yet to see >0.10 for a "car". For a "reasonably practical car", I still haven't seen anything less draggy than the Probe V.

I think Dave Cloud's Dolphin has a good chance of beating the Probe -- though it might need front wheel skirts? The overall shape beats the Prove V, hands down -- the Dolphin comes to a point at the back, fer cryin' out loud!
