Takuma Sato has been issued a 10-place grid penalty for an unauthorized engine change going into Sunday's IndyCar race in Sao Paulo, although its impact is negated by the fact that he would have started from the rear of the grid anyway after failing to make it out for qualifying.
The Rahal Letterman Lanigan team opted to make the change after second practice, and the weekend's condensed scheduled did not leave enough time for the job to be finished for qualifying.
"In the second practice I only ran a few laps before we had an engine problem which led to us not being able to take part in qualifying because of the amount of time it took to change the engine," said Sato. "The long straight with heavy braking here means you can overtake but starting from the back it is going to be tough."
Sato is one of two drivers to have been penalized for an engine change going into this weekend, with Dragon Racing's Katherine Legge having a penalty carried over from the previous round in Long Beach.
