Renault's all in one mirror and sidepod panel
The new Renault R27 mirrors are one of the most eye-catching novelties on the 2007 contenders. After Ferrari came up with the idea to put the mirrors on the outer side or the sidepod, several teams investigated the idea. Together with the sidepod panels that Renault introduced at Canada last year they make for a good combination of minimising drag. The new mirror position is especially beneficial because it is behind the front wheel and not visible on a front view of the car (and thus also not in the main air stream). The most important disadvantage is the distance of these mirrors from the driver's head, possibly combined with decreased stability.
It\'s these sort of seemingly trivial pieces of ingenuity that really make me love Formula 1 and engineering in general.
