Biffle: Hendrick hard to match

Biffle suggested at Lowe's Motor Speedway that Hendrick have completed far more miles of testing with the new car than rival teams, leading to the domination they have shown so far.

"They say that Hendricks have almost 100 days of testing in the CoT car," Biffle said. "I don't know if that's true or not. I don't know if that's double what they have. I have no idea.

"It seems pretty far-fetched to have that many days of testing in that car to date. I do know that they have done a tremendous amount of testing and spent a lot of time working with that car."

Given the advantage shown by Hendrick Motorsport with the Car of Tomorrow so far, the 2005 Nextel Cup Series runner-up believes it will be very hard to match them during the rest of the season.

"The hardest thing about catching up is it just like trying to catch up to somebody that's older than you in age," he added. "You're not going to get any closer because the more that they learn, the more you're learning.

"So you're both learning at the same acceleration, but you're behind them, so it's really hard to leapfrog and then get to their level. It's difficult to do."

The Roush Fenway driver was also critical of the new car, because it has not equalled the field as he expected.

"Everybody said that this car was going to level the playing field for everybody," he said. "That's the whole key to this CoT car, is it's going to level the playing field and put everybody on the same even keel. It hasn't done that to this point.

"It has, though, raised a few of the other teams, which it intended to do. So maybe it has brought the teams a little bit closer together. But it's not the great equalizer that everybody suspected it was going to be in the beginning."

Biffle has won the last two events held a Darlington Raceway, where the Nextel Cup will race next Saturday with the Car of Tomorrow. He says the unique nature of the 1.3-mile oval may provide an opportunity to beat the Hendrick teams.

"I think that what Hendrick kind of have dialed in as much may not be as big a factor there, since it's a faster place that is slick and you're on and off that bump stop - if that kind of makes sense."
