Today, NASCAR fans will get a sneak peek at Dale Earnhardt Jr.’s new-look paint scheme for the 2012 Sprint Cup Series season. Earnhardt, currently fifth in Sprint Cup championship points, will help introduce his 2012 Diet Mountain Dew paint scheme today at 1:40 p.m. ET on ESPN’s “SportsCenter.” Images of the car, which Earnhardt designed, will be available to fans of the Diet Mountain Dew Facebook page beginning at 2 p.m. ET.

If you remember, Diet Mountain Dew was featured on Earnhardt’s No. 88 Chevy at the inaugural Sprint Cup race at Kentucky Speedway in July. A variety of Diet Mountain Dew-themed paint schemes will run later this season at Loudon, N.H., on Sept. 25, Talladega, Ala., on Oct. 23, Martinsville, Va., on Oct. 30 and Phoenix on Nov. 13.

As it has since joining the No. 88 Hendrick Motorsports team in 2008, PepsiCo (20 points-paying races) will share co-primary sponsorship of Earnhardt’s Chevrolets with the National Guard (16 points-paying races) in 2012. A detailed schedule of paint schemes has not yet been determined.

The new No. 88 Diet Mountain Dew/National Guard Chevrolet will debut at the 2012 Daytona 500.
