Montoya happy with his progress

The Colombian completed three tests after he last raced at Homestead in November, including his first road course outing in a stock car.

"It's good. In December we did a road course test at Road Atlanta. That was a lot of fun. It was hard," he said.

"I think we were pretty competitive, but it's hard to be consistently quick. It's a lot of work. (The car) moves a lot more than anything that I've driven before. Then we went to Lakeland. I thought it went pretty well."

Montoya claims testing of the new Car of Tomorrow, which is set to be introduced during the season, will be key to his and his team's success this year.

"At the end of the day, once we get to the two-mile racetracks, where everybody is going to have the Car of Tomorrow, it's whoever did the best job in testing, is the team that is going to be ahead," he said.

"We need to focus on that, make sure when we get there, we've got the best package."

Montoya successfully tested last Friday Chip Ganassi's Lexus Riley prototype at Daytona's road course, in preparation for his first participation in the Rolex 24 Hours.

This year he could become one of only two drivers in history to win both the 24 Hours and the Daytona 500.

"Daytona, especially in America, is a big deal. It would probably be a very nice win if you could win it before the 500. To come here with the 24-hour win, would be pretty cool.

"You can't really say you're going to win it before you even start it, but so far everything looks pretty good."

Montoya will test again next week at Daytona in preparation for the Daytona 500.
