Biffle was born on December 23, 1969 in
Vancouver, Washington, and grew up in
Camas. He began his racing career driving on
short tracks around the
Pacific Northwest. He first gained attention as a driver when he raced in the nationally televised
Winter Heat Series in the winter of 1995–1996. Biffle dominated the series championship that winter, leading former ESPN announcer and NASCAR champion,
Benny Parsons, to recommend the driver to
Jack Roush. Biffle entered the first two races of the 1996
Winston West Series, finishing thirtieth at
Tucson and fourth at
Altamont. His debut in one of NASCAR's national divisions came later that year when he ran the final two
Busch Series races of the season. Driving a
Chevrolet for Dick Bown, he finished 23rd at
Rockingham but lost an engine the following race at
Homestead and finished 36th. In 1997, Biffle competed in the now-defunct
NASCAR Northwest Series and won the Most Popular Driver Award.
Truck Series Roush Racing promoted Biffle to a full-time driver in the
Craftsman Truck Series in 1998. Despite not winning a race that season, his four pole positions are the most by a Truck Series rookie to date, and they helped him earn an 8th-place finish in the final standings and the
Rookie of the Year Award. He followed it up with a stellar
1999 season in which he recorded nine wins, the single-season Truck Series record that stood (until
Corey Heim broke his record with 12 wins in
2025). He finished second in the final standings, just eight points behind champion
Jack Sprague. In
2000, Biffle won the
Truck Series title with another five-win season, beating his Roush teammate
Kurt Busch by 230 points. It was Biffle's first championship in one of NASCAR's three major series. It was announced that Biffle would move up to the Busch Series for 2001; however, he ran four more Truck races for Roush that season and won at Phoenix. Biffle made a Truck Series start in 2004 for another long-time Ford team,
Circle Bar Racing, at Homestead. at
Texas in 2019 On March 28, 2019, Biffle announced he would be testing with
Kyle Busch Motorsports the next day at
Texas Motor Speedway in the No. 51 truck. He was eventually tabbed to drive the truck for the
SpeedyCash.com 400 at Texas. Biffle started sixth and won in his series return, leading 18 laps and holding off
Matt Crafton while winning $50,000 in a promotion with
Gander Outdoors; it was his first Truck victory since 2001. On August 27, 2020, it was announced that Biffle would make another one-off start in the Truck Series, this time in the No. 24 for
GMS Racing at
Darlington. He went on to finish nineteenth.
Nationwide Series Biffle joined the Busch Series full-time in 2001 and won the Rookie of the Year Award with five wins and a fourth-place finish in the final standings. The following season, he won another four races and earned 20 top-five finishes out of 34 races en route to his first Busch Series title and the second NASCAR national championship of his career. Biffle ran only part-time in Busch competition in 2003 as Roush moved him up to a full-time ride in the
Winston Cup Series for that season, but he returned to contend for the Busch Series championship again in 2004. He placed third in the standings behind
Martin Truex Jr. and
Kyle Busch. From 2005 to 2009, Biffle raced part-time for Roush Fenway Racing in the Busch (now O'Reilly Auto Parts Series) every year. He won twice in 2009, at
Las Vegas and
Phoenix, after going winless the previous two seasons. Biffle returned to the Nationwide Series in 2010, driving the No. 27 Ford for
Baker Curb Racing.
Cup Series in 2005 Biffle began his Cup Series career in the 2002 season. He attempted to qualify in a Roush Ford for the
2002 Daytona 500 but failed to make the race. He would make his first Cup debut nine races later at
California, a race in which he finished thirteenth. That was his best finish in seven races that year as he also drove four in a Chevrolet for
Andy Petree Racing and two in a Dodge for
Petty Enterprises. Biffle began competing full-time in NASCAR's top division in
2003, with sponsorship from
W. W. Grainger, who had previously sponsored him in the Busch and Truck Series. He earned his first win in the
Pepsi 400 at
Daytona that season and finished second to
Jamie McMurray (who would later join him as a teammate at Roush) for Raybestos Rookie of the Year. His Daytona win made him the first Winston Cup winner to succeed in all three of NASCAR's national series in succession (as opposed to others who won in the Busch or Truck Series after graduating to Winston Cup); a feat which has since become quite common for young stock car drivers climbing the ladder. Biffle placed twentieth in the final points standings. Biffle made an immediate impact in his sophomore season in 2004, earning the pole in the Daytona 500. However, Biffle was forced to start at the rear due to an engine change. Despite missing NASCAR's first-ever
Chase for the NEXTEL Cup, Biffle won twice that season, at
Michigan and Homestead en route to a 17th-place finish in the final points standings. 2005 was Biffle's breakout season. He won six races (at California Speedway, Texas, Darlington, Dover, and Michigan along with the season finale at Homestead), the most of any driver that year, and qualified for the Chase for the first time in his career, bringing home a second place finish in the standings, 35 points behind champion
Tony Stewart; Biffle tied with his teammate
Carl Edwards in points but won the tie-breaker based on race wins. Biffle regressed in 2006, missing the Chase for the Cup despite winning twice at
Darlington Raceway and
Homestead-Miami Speedway (both of which were tracks at which he had also won in the previous season). He finished thirteenth in the standings, third-best of the drivers not to qualify for the Chase. He also missed the Chase the following year, in a season marred by the No. 16 team's new primary sponsor
Ameriquest Mortgage suffering financial difficulty and having to sell off a number of its race sponsorships. Biffle won only one race in 2007, at
Kansas Speedway. As Biffle was doing burnouts on the track, third place
Jimmie Johnson and second place
Clint Bowyer accused Biffle of not maintaining speed under a final lap caution, but this was denied by NASCAR, which said Biffle had pace car speed. In 2007, Biffle finished 14th in the standings, second-best of the non-Chase drivers as the Chase expanded to a twelve-driver format that year. in 2008 In June 2008, Biffle signed a three-year-long contract extension with Roush Fenway Racing. Despite going winless during the 26-race regular season, Biffle made for the Chase for the Sprint Cup that year and won the first two Chase races, at
New Hampshire and
Dover. In doing so, he became the first driver to win the first two Chase races in a season. Biffle qualified for the Chase for the second year in a row in 2009 but, for the first time since 2002 (when he ran a limited schedule), failed to record a win. During a test in January 2009 at Texas World Speedway, Biffle managed to reach in a test for
Roush Fenway Racing as part of evading NASCAR's testing ban. This became the fastest time ever achieved on this track by any competitor (amateur or professional). In 2010, Biffle qualified for the third year in a row for the Chase despite spotty performance in the regular season. He won twice at Pocono and Kansas. In 2011, Biffle's season improved, thanks in part to the implementation of Ford's new FR9 engine. However, crew chief
Greg Erwin was replaced after Kentucky by Matt Puccia. The addition of Puccia helped Biffle's performance late in the season, despite the team missing the Chase and finishing sixteenth in points. Biffle missed the Chase in 2011 for the first time since 2007. In 2012, Biffle and Puccia remained at RFR and gained the points lead after Las Vegas after three consecutive third-place finishes. At the
2012 Daytona 500, Biffle found himself second coming to the white flag for the third time in two years and again finished third. Eerily, the third place at Vegas came in Biffle's 333rd Cup start. Biffle's first win of the 2012 season came at
Texas Motor Speedway in the
Samsung Mobile 500 after passing
Jimmie Johnson with thirty laps left in the race. Biffle won at Michigan holding off Brad Keselowski after Jimmie Johnson blew an engine. Biffle started off 2013 by being in the same position for the third time in four years; in second place coming to the white flag in the
2013 Daytona 500, but this time ended up sixth. In the
2013 Quicken Loans 400 at Michigan, Biffle won his fourth race at the track and the 1,000th victory for Ford. At the
2014 Coca-Cola 600, Biffle surpassed
Clint Bowyer's record for most consecutive races without failing to finish with 84, tying
Herman Beam's record, dating back to the
2011 Ford 400. The following week at the
FedEx 400, he broke Beam's record by finishing the race 108 laps down in 38th. Later in the season, he finished with a DNF for the first time in 89 races after a wreck in the
Coke Zero 400, finishing 29th. Biffle began the pre-season with an announcement that he would stay at
Roush Fenway Racing to help the team with a new sponsor
Ortho. Biffle began 2015 with a tenth-place finish in the
Daytona 500. Unfortunately, that was as good as it could get for Biffle as he faded outside the top twenty in points. He struggled mightily before picking up a second-place finish in the
2015 Coca-Cola 600, after starting fourth. He went on to pick up a fifth-place finish at Pocono in the
2015 Windows 10 400 and a fourth-place at New Hampshire in the
2015 Sylvania 300, finishing twentieth in points. Ortho announced it would depart Roush following the 2015 season, leaving Biffle without a primary sponsor for the
2016 season. KFC then announced it would sponsor Biffle throughout Speedweeks and in the Daytona 500. He earned his first pole position in four seasons during qualifying for the
Coke Zero 400 at Daytona and went on to finish eighth in the race. After finishing 23rd in points in
2016, Biffle and Roush Fenway mutually parted ways, making Biffle a free agent for the upcoming 2017 season. He did not sign on with a ride for the 2017 season. Biffle returned to the series in
2022, driving the No. 44 for
NY Racing Team at the
Daytona 500 and the remainder of the team's races that year as well. He was originally rumored to drive the No. 44 for
NY Racing Team in the
Daytona 500 in 2024, although he announced that he would not be in the car due to "unfulfilled contract obligations" from 2022, and would not drive any races for the team until said obligations are fulfilled, and was replaced by
J. J. Yeley, despite his name still displayed on the car and firesuit.
Stadium Super Trucks in 2018 On August 21, 2018, Biffle tested a
Stadium Super Truck that was driven by fellow ex-NASCAR driver
Casey Mears. A day later, he announced he would make his series debut at
Road America. He finished seventh and second in the weekend's two races, though he did not receive points in the standings as he drove the No. 57 truck in place of
Bill Hynes, who received the points earned by Biffle under series rules. Biffle returned to SST for the 2019 season, sharing a
Continental AG-sponsored truck with
Sheldon Creed and
Ryan Beat. He ran his first races of the year in late July at
Mid-Ohio Sports Car Course. In the weekend's first round, he battled with
Gavin Harlien for the lead until Harlien began suffering mechanical trouble; on the final restart,
Cole Potts passed Biffle to take the race win. The second round saw Biffle pit under caution for damage, but was able to finish fourth. In October, he ran his first SST race in Australia at
Surfers Paradise Street Circuit. In practice, he was the fastest in the ten-driver field but did not set a qualifying time after flipping his truck when he hit a tire barrier. He ran in second for much of the first race before falling to fourth after an erratic landing; the second race saw a late spin drop him to eighth. After not racing in 2020, Biffle rejoined the series at the 2021 Mid-Ohio NASCAR weekend. He finished second in Race 2.
Superstar Racing Experience In 2021, it was announced that Biffle would pilot the No. 69 car in select
2021 Camping World SRX Series races. He started his season off at the inaugural SRX race at
Stafford Motor Speedway, winning the first heat but getting caught up in a wreck in the second heat. For the main event, he switched to a backup car and drove to second by the end of the race, behind only
Doug Coby.
Other racing In 2003, Biffle competed in the
International Race of Champions. He recorded a best finish of third at Talladega and finished seventh in points. Biffle, along with Roush teammates
Kurt Busch and
Matt Kenseth, raced at the
2005 24 Hours of Daytona for
Multimatic Motorsports. The team lost a halfshaft during the race and finished 27th. In 2018, Biffle started the Sand Outlaw Series for racing
UTVs. Since then the series has grown into a popular multi-class drag racing championship featuring hill climbs and flat track events. He competed out of his own UTV shop, Pace Offroad. ==Personal life==
