@RedBullNASCAR tweeted earlier today that they had finally brought new 2011 Kasey Kahne merchandise onto their website. This is where fans found out that he will be in the 4 car.
After splitting from Richard Petty Motorsports back in October after an off-track incident, Kahne went directly to Red Bull Racing for the remainder of his season. All in all, it was a success: two top 15s and a sixth-place finish at Homestead- Miami, where he also got the pole.
Kasey Kahne and Red Bull Racing hope that this early start will give them momentum into the 2011 season. Hopefully, we will be seeing that new 4 car up in the front!
P.S. Here is a sneak peak of the car: http://plixi.com/photos/home/62788954.
