Note from the CRB:
When the P1 and P2 classes were inaugurated in 2014, they were intended to occupy
different spheres of competition, with P1 conceived as the premier class promoting advanced
technology and innovation, and P2 envisioned as a lower-cost alternative through restrictions
on chassis materials, engine power, and vehicle aerodynamics, but the contrasting class
philosophies have not translated into the expected difference in lap times. Despite making
various adjustments to specifications over the past five seasons, the front-running P2 cars
remain capable of producing lap times that to most observers are essentially indistinguishable
from the lap times of P1 cars. Accordingly, effective March 1, 2019, additional changes are
being made to the leading P2 platforms to achieve an appropriate lap-time gap between the
P1 and P2 classes, while leaving the specifications of the P2 spec line cars unchanged to
promote more equal competition between the different types of P2 cars. The CRB will continue
to monitor class performance and make further adjustments as necessary.
