Could someone explain this twin-keel thing? I've been trying to understand it but no articles really explain it that well; they primarily blow it off. Sauber went back to the single keel for '04 after using the twin for a couple of years.

In retrospect, it was all downhill from here. RIP, CEG.

Well, it took me a while to dig up some information on this twin-keel thing, but I think I have it answered.
The new twin-keel design actually serves two very important purposes. First, and perhaps most importantly, it is specifically designed to do more damage to the other cars when Juan Pablo slams into them from behind. Second, the new design doubles as a front loader to regrade the kitty litter when Ralf and Juan have an off.

From http://www.grandprix.com/ns/ns12323.html"The effect of this is that the airflow is cleaned up much more than was previously the case and is then further compartmentalised by the use of the "twin-keel" layout under the nose. Cleaning up airflow means that the air is less disturbed (and therefore more efficient) further back in the car - and specifically around the rear wing. The channelling of the air means that the sidepods are not as wide as previously, which means that drag is probably reduced."Originally posted by bigMoneyRacing:

Yep, understand that, sort of. It'll probably take pictures for me to really get it. They need to start introducing cars like the America's Cup yachts.

AFAIK, "twin-keel" refers to the underside of the chassis (body), which appears concave when viewed from the front (like an inverted U). "Single-keel" designs are either flat or slightly convex. I think some suspension components are mounted to each keel in a twin-keel design.

Seems sort of like "ground effects" to me.
