On the other hand understanding and development of F1 aerodynamic design is possibly reaching its peak in terms of the good ol' law of diminishing returns. Next year a lot will rest on the new formula for the power units*. There are some new variables in the mix that may be to the advantage or otherwise of the power unit engineers. The challenges for them will be to develop and integrate the V6 engines, turbo units and ERS's into the best package. They will have to engineer a host of solutions with regard to the chassis, suspension, tubs, etc. Newey will certainly be an edge for RBR with regard to the bodywork but will it be enough?
*Note: They're not calling them engines in 2014, apparently!
