Will Power opened this weekend's IndyCar season finale at Fontana by setting the fastest time in the first practice session.
Penske driver Power set the 220.889mph benchmark right at the beginning of the 90-minute session and it held right through to the end.
KV's Tony Kanaan came closest to matching it, but the Indianapolis 500 winner's best effort was still 1mph shy of the Australian's time.
James Hinchcliffe and AJ Allmendinger were third and fourth-fastest, the latter having been entered in a third Penske car for the weekend to assist with Helio Castroneves' title bid. The Brazilian finished the morning with the fifth-best time, putting him one place ahead of championship rival Scott Dixon.
The session was red-flagged twice following heavy accidents at Turn 4.
Pippa Mann, who takes over the second Dale Coyne Racing entry this weekend, caught a seam and crashed heavily into the wall on her seventh lap; her badly damaged car eventually spinning to a stop on the track's apron.
Later, Takuma Sato did almost exactly the same thing, and with more or less identical results. Both drivers were checked and cleared by IndyCar's medical team.
Meanwhile, Carlos Munoz was confirmed as the stand-in for EJ Viso in Andretti Autosport's #5 car. The Venezuelan withdrew from the race last night citing an illness. Munoz was 24th fastest.
