Dale Earnhardt Jr. fans will pick the No. 88 team's paint scheme for next month's NASCAR Sprint Cup Series race at Michigan, choosing between one of four designs related to July's release of The Dark Knight Rises.
The Batman film has a tie-in with Earnhardt Jr. sponsor Diet Mountain Dew, which gives the driver's "Dew Crew" a chance to vote on which car they like best.
Check out the four possibilities below:
Earnhardt Jr.'s Dew Crew is an online hub for No. 88 team and Diet Mountain Dew fans where the sponsor offers an opportunity for supporters to have their voices heard. It's located on a Facebook page linked from DewCrew.com.
The site gave away Earnhardt Jr.'s Daytona 500 firesuit from this season and lets fans help make decisions such as the Michigan paint scheme.
So why Michigan and why the tie-in? It's because on the morning after the Michigan race (June 18, to be exact), Mountain Dew is kicking off a huge promotional push related to the Dark Knight movie.
It includes a site called DewGothamCity.com, which gives fans an inside look at the film, and a Batman-themed flavor called "Mountain Dew Dark Berry."
To vote on Earnhardt Jr.'s car, you'll have to join the Dew Crew by liking its Facebook page. Here's a video Dale Earnhardt Jr. made to explain more:
