In my latest blog, I delved into why Indycar pitstops are slower than their F1 counterparts. The primary reason is the difference in manpower; Indycar only allows six crew members, while F1 permits about twenty. Consequently, more tasks in Indycar stops are performed sequentially instead of simultaneously, leading to lengthier stops. Furthermore, Indycars have refueling during pitstops, which F1 phased out in 2010, adding to the duration. Lastly, the design of the Indycar, with its larger tires, also adds a few valuable seconds to pitstop times.
