Beautiful sunny and dry conditions greeted the drivers for a straightforward half hour Sunday morning warm-up practice, ahead of this afternoon's Edmonton Indy.
The session ran without any stoppages, although there was one moment when Helio Castroneves appeared to give Ed Carpenter a wake-up bump for getting underfoot in the closing minutes that raised eyebrows and won him a drive-thru rap on the knuckles from race control; and Ryan Briscoe had a big lock-up while trying to get past Simona de Silvestro through turn 1 late in the session..
Few cars appeared to be really pushing to the limit during the 30 minute track opportunity and were generally treating the session as a shakedown lap to check for race worthiness rather than logging fast times.
Birthday boy Scott Dixon was one exception to the rule as he went fastest, ending up the only man to duck under the 1:17s mark with a lap of 1:16.9006s over half a second clear of Rubens Barrichello and Mike Conway.
Will Power pushed early and had a few run-offs during the session as a result, but without setting a strong lap time: he finished down in 20th on the timesheets with a lap of 1:18.5801s - as he bedded in the #12's new engine that had been fitted overnight following Saturday's qualifying session. That was after Penske opted to make the change in order to take advantage of the newest specification Chevrolet unit for the race.
As a result, Power will start from 17th place on the grid, alongside Scott Dixon who takes a similar grid hit after an engine change post-Toronto. Power's main rival for the 2012, Ryan Hunter-Reay, also has a grid penalty and will start from 11th after winning pole position on Saturday.
Oriol Servia was another driver added to the list of those on the penalty step for the start of the Edmonton race for a new engine, which will likely drop him to the back row of the grid alongside Simona de Silvestro who was the final one of the five drivers to be demoted on the grid. Servia was another driver looking to bed in his engine, even if it meant being a regular visitor through the run-off sections of the track in the process.
With so many cars out of their natural starting positions thanks to penalties and getting caught out in the rain-hit qualifying session, it should be an entertaining time watching drivers fighting their way back through the field during the 75 laps of the 2.24-mile, 13-turn temporary circuit constructed on the runways at Edmonton City Center Airport.
The corners that presented the most problems for the drivers during the practice sessions should also give them the most opportunities to pounce on the mistakes of others for overtaking chances in the race itself.
