Formula One should prioritise implementing a spending cost cap if it wants to reduce the large performance gaps that currently exist in the sport, according to Williams technical chief Paddy Lowe.
The dominance of Lowe's former team Mercedes since the introduction of 1.6 litre V6 hybrid engines in 2014 has led to criticism of F1, prompting the sport's rule makers to find a path to help level the playing field. An aerodynamic regulation overhaul over the winter enabled Ferrari and Red Bull make significant gains on Mercedes, but the German manufacturer was still able to wrap up both world championships before the end of the season.
