Analysis: DPi and P2 Balance of Performance

The big talking point for the 2017 IMSA WeatherTech United SportsCar Championship season is the introduction of the Daytona Prototype International (DPi) class. Much like 2014, where IMSA officials tried in vain to balance the performance of the now retired Daytona Prototypes and the fresh crop of LMP2 cars, the 2017 Prototype class will again be defined by its BoP.

Second, I wanted to do a sound comparison of the new-for-2016 GTLM cars. Two raucous V8s were replaced by turbos; I thought it would be interesting to compare.

Analysis: Timing Data From The Continental Tire Monterey Grand Prix

Mazda Raceway Laguna Seca rewards smooth and committed driving. Without the top speeds of Daytona or the stop-and-go cornering of Long Beach, cars and drivers need to keep their momentum up and maintain a high minimum speed through the corners. On paper, this should play right into the hands of the LMP2-based machinery.
