Firstly, this site is fantastic! Well done Tomba, CFDruss et al.
Well. I think the R24 is the most elegant F1 car released thus far - it's just pure eye-candy. Renault has optimised chassis package space to a degree that rivals that of the new McLaren, and together with logical, much improved, aerodynamics the R24 looks a winner. The change to a 72 degree engine config. seems to be a logical step too. Ok, to my questions:
Do side chimneys (ala FW26 and R24) offer the best return (cooling) vs aerodynamic penalty? And what are the aerodynamic penalties of having chimneys (+ the exit stream of post coolant air)?
What advantages does the implementation of 'shark grills' offer?
And why does Renault test the R24 with covered chimneys (see below)?
