IndyCar championship leader Will Power isn’t thinking of glory just yet as he goes into this weekend’s race in Baltimore.

The Australian won the inaugural Grand Prix of Baltimore last year, leading 70 of 75 laps in another display of his road-course dominance.

And if he can replicate that performance this weekend, Power could possibly leave the city with the 2012 IndyCar championship locked up before the final race of the year.

Power holds a 36-point lead over American Ryan Hunter-Reay going into this weekend’s second last race after his second placing behind compatriot and teammate Ryan Briscoe in the previous race at Sonoma.

Should Power extend his lead to 54 points or more by the time he leaves Baltimore, he’ll have the championship all sewn up.

But the Queensland product says he’s not trying anything special with the title on the line.

“We will go into this week just as we do every week and that is to get a win,” he said.

“We would obviously like to repeat last year’s success and, once we get some practice time, we will be able to see how the new changes affect the way we attack the track.

“Hopefully we can follow up last week’s great wins for both Team Penske and Team Chevy with another one this week.”

Briscoe’s win over Power at Sonoma was the seventh of his IndyCar career and first since Texas in 2010.

The Sydneysider is eighth in the championship and said he’s keen to build on his Californian success.

“I’m excited to be returning to Baltimore,” he said.

“It was a very challenging course last year and, with the changes they are making, we’ll have to see how things play out this year.

“Last year, we were having a strong run after qualifying fourth so we will try and pick up from what we learned there last year.”

Qualifying for the Grand Prix of Baltimore begins on Saturday (Sunday AM AEST) with the 75-lap race to be run on Sunday (Monday AM AEST).
