TALLADEGA, AL - Greg Biffle and his main sponsor have renewed their contracts with Roush Fenway Racing through the 2014 season.
3M first sponsored Biffle's No. 16 Ford in 2005 and came aboard as a primary sponsor for Roush in the Nationwide Series the following year. In 2008, the company moved up to sponsor Biffle's Sprint Cup program on a full-time basis.
Since then, Biffle has won four races and reached the Chase for the championship three straight years. This deal keeps the partnership going for at least another three seasons.
The 41-year-old Biffle says he "couldn't ask for a better sponsor relationship." He's been with Roush Racing since 1998 and won 16 Cup races.
