Plenty of star power at final day of testing

On NASCAR's part, this year's season-opening test was a sharp contrast to that of 2012, when the sanctioning body spent three days tinkering with the superspeedway rules package in an attempt to break up two-car drafts and to scale down speeds that exceeded 206 mph.
 
Even though the Cup series is transitioning to a new Generation-6 race car, the 2013 sessions required little manipulation on NASCAR's part. Average lap speeds in the draft topped out at the 199.650 mph achieved Friday afternoon by 2011 Daytona 500 winner Trevor Bayne, and NASCAR was comfortable with the results.
 
"We're in the ballpark," said Robin Pemberton, NASCAR vice president of competition. "We know the teams will go back, and they'll work and they'll bring a little bit better ‘this' and better ‘that.' … We're right in the ballpark, and we don't foresee any changes."
 
Pemberton acknowledged that one consideration in designing the Gen-6 cars was breaking up the tandem racing, which was not a fan favorite.
 
"When it was new, it was cool," Pemberton said of the aggressive two-car push-drafting. "When it was a couple races old, the coolness wore off of it. It was something that wasn't very normal for us.
 
"If you saw us last year at this time, we left this race track drafting at 206 miles an hour and went back and made rule changes based on trying to minimize the advantage of doing that (tandem drafting) and to minimize the appetite to do that, knowing that -- if it was the fastest way around -- you would do that late in the race to win the race."
 
Ryan Newman was first to top 194 mph in single-car runs Saturday afternoon, posting a lap at 194.083 mph as the session moved toward conclusion.

Greg Biffle finished with the top time of the day, posting a speed of 194.936 mph on his 23rd and final lap.

Matt Kenseth, who posted the top time in the morning session, was second in the afternoon session. Joe Gibbs Racing teammate Kyle Busch was third on the afternoon.
