"I think you guys are expecting me to go out and win my very first race, but I don't think that's going to happen," Montoya cautioned. "But I'm 100 percent committed to this - it's the only thing I'm going to be doing - and we're going to need to make this work."

Montoya has another test scheduled for Iowa Speedway later this week, and team boss Chip Ganassi plans on making a decision regarding the driver's racing debut based on Montoya's performance.

"I think for starters, what Juan said earlier was pretty important," Ganassi said. "He said he makes changes on the car and the car reacts to changes. He is here today learning about driving this type of car, not only on this type of circuit, but it's about interacting with the people on the team. It is about his interaction with Donnie. It is about them getting on the same page in terms of communicating. Every time you bring a new driver to a new crew chief, or a new engineer, even though they speak the same language, you'd be surprised how difficult it is to communicate some things that happen in cars. So, it is about getting in a comfort zone with that level of communication.

"We are just scratching the surface of the iceberg here in terms of communication today, just getting a feel for what drivers like, what they don't like, what they really mean when they say the car is "tight." Is that a big tight, not a lot tight, a little tight? There are all levels of that. You might divide that word 'tight' into about 50 different subsets. So, when you talk about what the next race is going to be and what is going to determine it, that is all part and parcel of what goes into that decision, if that makes sense.

"We will evaluate the tests, see how he is feeling about the transition and make a decision regarding other tests and possible races based off that information," Ganassi said.
