The member may contest the imposition of the penalty pursuant to the procedures and timelines detailed in the review and appeal procedures of the Verizon IndyCar Series rulebook.
As for what the rules mean, from the rulebook, here’s the actual language (h/t to James Black of 16th and Georgetown who had these posted up to his site, as well).
11.2 Torque Control – The only means by which the driver may control the engine torque is via a single chassis-mounted foot pedal or on-board fuel mixture switch. Designs which allow specific points along the pedal travel range to be identified by the driver or to assist in holding a position are not permitted. The minimum and maximum pedal travel positions must correspond to the engine throttle minimum (normal idle) and maximum open positions.
It is permissible to take control of the engine torque away from the driver during any of these events only:
a) When a stuck throttle is detected
b) During a gearshift
c) For pit lane speed limit control
d) For engine rev limit control
e) To control over boosting
12.1 Traction control – Traction or launch control is not permitted.
INDYCAR also announced that the race winning car of Simon Pagenaud was fined $1,000 for violating Rule 188.8.131.52 (Underwing splitter) and Team Penske’s No. 3 entry was fined $1,000 for the violation of Rule 14.15.7 (Differential assembly).
Those read as follows:
184.108.40.206. All of the remaining underwing parts (splitters, sidewall extensions etc.) must remain as supplied with the exception of adding extra fasteners or the permitted trim to the underwing sidewall.
14.15.7. All parts of the differential assembly must be used as supplied by Xtrac.
