Renault compromise front aero for tyres

As of the beginning of tyre testing with Bridgestone, Renault realised the weight bias had to move forward compared to what the team used with Michelin. However, as testing went on, it appeared more was needed, and so the team decided on a redesign of the highly efficient nose to a cone with more internal volume. The nose of the R27 (above part of image) resembles more to the nose of the R25, which afterall was the predecessor of the R26 (lower part of image). The solution that Renault came up with allows for the race engineers to put more ballast into the nose and is similar to what Ferrari came up with after they introduced their F2004M. Back then it was the beginning of an uncompetitive season for Ferrari in 2005.
