The NASCAR Sprint Cup Series heads to Auto Club Speedway in Fontana, Calif., this weekend to race its new “Generation 6” cars on a 2-mile track for the first time.

The first four races of the season were on tracks that were 2.5 miles (Daytona), 1 mile (Phoenix), 1.5 miles (Las Vegas) and a half-mile (Bristol).

Stafford Township native Martin Truex Jr. said the best comparison for Fontana’s 2-mile D-shaped oval is Las Vegas.

“I think California is going to be a place where we can run well based on how we raced at Las Vegas Motor Speedway,” Truex, who finished eighth at Las Vegas, said in quotes provided this week by his team, Michael Waltrip Racing. “I think we are going to see a very competitive race. This new car is going to change some things up. It’s got more downforce and more speed. Auto Club Speedway is already really fast.”

Truex said he expects to see unusually fast speeds there.

“I think the really good thing about this track is the groove,” he said. “It is all over the track. It’s going to allow us to put on a great race for the fans. It’s going to allow us to pass a lot.

Truex has finished eighth and 12th the past two weeks after mechanical failures the first two races. He is 18th in the standings but wants to keep moving up.

“My plan is to keep it simple and just be faster than everyone else. That’s it. How hard can that be?” he said.
