MB2 Motorsports was a NASCAR Cup Series team based in Mooresville, North Carolina, near the sport's hub in Charlotte. The team was founded by Read Morton, Tom Beard, and Nelson Bowers, from which the original team name derived. Bowers was the longest tenured of the original owners, and the listed owner of the teams' entries when resort and real-estate developer Bobby Ginn bought out the team in 2007, renaming it to Ginn Racing for that season only. The Valvoline corporation co-owned the No. 10 car with the principal owners from 2001 to 2005 as MBV Motorsports, while the No. 36 entry was co-owned by Centrix Financial, LLC owner Robert Sutton as MB Sutton Motorsports in 2005.

Virgil Earnest "Ernie" Irvan, occasionally referred to as Swervin' Irvan, is an American former professional stock car racing driver. A retired NASCAR competitor, he is perhaps best remembered for his comeback after a serious head injury suffered from a crash during practice at Michigan in 1994 that left him with only a 10% chance of survival. Irvan has been inducted into numerous halls of fame and was named one of NASCAR's 50 Greatest Drivers in 1998. After a series of injuries in the late 1990s, he retired from racing in 1999.
