The introduction of DRS and rapidly-degrading tires in 2011 boosted on-track overtaking levels in Formula 1 to unprecedented highs. Since then, overtaking has steadily decreased again, culminating in a 60-percent reduction in 2017. In this paper, using a Poisson model on individual-level overtaking data from 2011 to 2018, it was found that about half the decrease can be attributed to the cars, 20 to 30 percent to the reduction in field size and about 20 percent to more uniform race strategies. Keywords: Formula 1, overtaking, quantitative analysis 1. Introduction Bridgestone pulled out of the sport and was replaced by Pirelli. The 2011 season would become the start of Overtaking is an essential ingredient in motor rac- the high-tire-degradation era, as Pirelli was required ing. However, in Formula 1, overtaking has been to artificially increase tire degradation. Along with somewhat difficult since at least the 1980s due the change of tire suppliers, DRS (Drag Reduction to the strong reliance on aerodynamic downforce, System, a driver-adjustable rear wing to increase top which creates wake turbulence (Mafi, 2007; Newbon, speed) was introduced to boost overtaking.
