So far, the 2013 season has produced two Sprint Cup Series races on two entirely different tracks and this weekend the teams are in Las Vegas, with yet another different type of track for the drivers. Daytona is a super speedway and Phoenix is considered a one-mile short track.

But the most widely raced track on the Sprint Cup circuit is the 1.5-mile intermediate track, and that’s what drivers will race for the first time this season at Las Vegas Motor Speedway with their new generation six cars. Although it’s not their first Gen6 test on a 1.5-mile track, Las Vegas does represent their first full race on an intermediate venue.

How important is the extra test time scheduled for Thursday?

“Without a doubt the 1.5, two-mile tracks can make your entire season. That test day is going to be huge,” said Steve Letarte, crew chief of the No. 88 driven by Dale Earnhardt Jr., who finished in the top-ten in every 1.5- and two-mile race he ran in 2012. “As a crew chief, you are trying to figure out what area you should be working in.”

Rodney Childers, who oversees the No. 55 Toyota that Mark Martin put on the pole a week ago at Phoenix, agrees.

“With it being an intermediate track and a place that’s really fast, the aero part becomes the biggest thing that you fight and I think everybody in the garage needs to learn a little bit [more] about this new car and where the splitter needs to be compared to the race track,” Childers said.

Although teams tested the Gen6 car in Charlotte, also a 1.5-mile track, in January, there are some differences presented to drivers for their test at Las Vegas. The most obvious difference being weather conditions. But there’s more for drivers to consider as well. Continue reading →
