Here, Scott lists CdA, which is the coefficient of drag (related to shape only) multiplied by frontal area. At 12 m/s(43.2 km/h), Foil creates around 4 watts more drag than the Cervelo S5 (76 watts for Cervelo and 80 watts for Foil, excluding rider)
From the other standpoint, stiffness,

Scott Foil is listed stiffer than the Ridley Noah and the old Felt AR1. The test is 3 years old though, and only Foil and Noah were not updated until today.
So, aero and stiff. A viable alternative in my book.
I have nothing to back up that the Aeroad is stiff but I'd have thought the Aeroad was built to be stiff.
I would more than like to see other test results, and eat my words if those contradict what I say.
Sorry for the hijack.
