This weekend at Las Vegas will be the first time this season the new Generation 6 car gets a test on a mile and a half track, so drivers were on the track on Thursday for testing to get a better idea how it going to handle on intermediate tracks.  They’ll also practice Friday and Saturday as well.

Las Vegas is the first of 11 Sprint Cup races at mile and a half tracks this season.
After two races this season drivers have already noticed the Gen-6 car is faster with more downforce and better grip than in the past, but passing is tougher to do and there’s not much side-by-side racing.

But it could be different story this weekend because it’s a wide racetrack.
Jimmie Johnson holds an eight-point lead after winning at Daytona and coming in second at Phoenix.  He has the most wins at Vegas with four including three in a row.

Tony Stewart is the defending champion.

Stewart, Jeff Gordon and Mark Martin have the most Top Five finishes each with six.

It’s a 400-mile race, 267 laps.  Green flag around 3:15 Eastern.

Nationwide drivers are also at Vegas on Saturday where Kyle Busch looks to extend his career win total to 53 at his home track.
