Gregory Jack Biffle, nicknamed "the Biff", (born December 23, 1969) is an American semi-retired professional stock car racing driver.

After racing in the NASCAR Winter Heat Series in the mid-1990s, he was recommended to Jack Roush by former racer and announcer Benny Parsons.

Biffle dominated the series championship that winter, leading former ESPN announcer and NASCAR champion, Benny Parsons, to recommend the driver to Jack Roush.

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.

In 2000, Biffle won the Truck Series title with another five-win season, beating his Roush teammate Kurt Busch by 230 points.

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.

[4] 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.

[6] 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.

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 3 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.

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.

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).

[citation needed] In 2007, Biffle finished 14th in the standings, second-best of the non-Chase drivers as the Chase expanded to a 12-driver format that year.

He Won At Kansas During The Chase In 2007 In June 2008, Biffle signed a year-long contract extension with Roush Fenway Racing.

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.

The addition of Puccia helped Biffle's performance late in the season, despite the team missing the Chase and finishing 16th in points.

[9] In 2012, Biffle and Puccia remained at RFR and gained the points lead after Las Vegas after three consecutive third-place finishes.

Biffle's first win of the 2012 season came at Texas Motor Speedway in the Samsung Mobile 500 after passing Jimmie Johnson with 30 laps left in the race.

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.

[17][18] On August 21, 2018, Biffle tested a Stadium Super Truck that was driven by fellow ex-NASCAR driver Casey Mears.

[21] Biffle returned to SST for the 2019 season, sharing a Continental AG-sponsored truck with Sheldon Creed and Ryan Beat.

[26] 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.

[32] Biffle, along with Roush teammates Kurt Busch and Matt Kenseth, raced at the 2005 24 Hours of Daytona for Multimatic Motorsports.

[34] The series has since grown into a popular multi-class drag racing championship featuring hill climbs and flat track events.

He is of German and English descent as his ancestor, Johannes Büffel (1728–1804) came from Contwig in Western Germany and settled in North Carolina.

[42] On February 17, 2017, Biffle announced that instead of racing full-time in 2017, he would join NBC Sports' NASCAR America as an analyst beginning March 1, 2017.
