- AJ Allmendinger has the most starts in #84 with 38 for Red Bull Racing. AJ first piloted the #84 in 2006 at Atlanta motor Speedway driving a Dodge Charger for the new Red Bull Team, but he failed to qualify due to rain.
AJ and the Red Bull team would field Toyotas full time in 2007. After a crash in his Duel Qualifying race, AJ failed to make the 2007 Daytona 500 and thus struggled to acquire enough owners points to be locked into races. AJ found the most success in the races with the “Car of Tomorrow” which was being phased in during the 2007 season. Allmendinger started 17 races that year.
In 2008 Allmendinger again failed to qualify for the Daytona 500. He would be replaced by Mike Skinner for 5 races to help the team gain qualifying consistency. After returning to the team, AJ and the team were able to win the “Sprint Showdown” and qualify for the 2008 All Star Race.
AJ started 21 races for the team in 2008, but just 2 days after his best finish of 9th at Kansas he was released from the team. Mike Skinner (7 total starts) and Scott Speed (4 starts) would drive the car for the remainder of the season. Brian Vickers made 1 start in the car at Homestead in 2008. He and Scott Speed switched cars in an effort to qualify both for the race. For the 2009 season the team would renumber the car to #82.
- Cole Whitt had a long-standing partnership with Red Bull, and drove the #84 car for Red Bull Racing in his days in the K&N Pro Series. In the final 2 races of 2011, Team Red Bull revived their #84 car for Whitt to drive in the Sprint Cup Series. Following the 2011 season Team Red Bull sold all their assets to the team now known as BK Racing.
- During the 1989 season Dick Trickle started the #84 car 28 times. This would be Trickle’s first full time year in the Cup Series, after many successful years in the now defunct American Speed Association. Trickle was named Rookie of the Year for the 1989 season.
- Jody Ridley started the #84 in 25 races- one in 1977 and the rest between 1983-1984. In these starts Ridley earned 6 top-10 finishes, but also 11 DNFs.
- Kyle Busch started 6 of 9 attemped races in #84 in the 2004 season. Busch was driving for Hendrick in the Busch (XFINITY) Series at the time, and started #84 (reverse of Jimmie Johnson’s #48) in preparation to take over for Terry Labonte in the Hendrick #5 the next season. His best finish in the number was 24th at California Speedway.
