Auberlen was born in Redondo Beach, California, located in the Los Angeles metropolitan area and attended Rolling Hills High School. His career started in the 1970s in motocross, with Auberlen moving to IMSA GTU in 1987. He stayed there until 1997, his last year resulting in him winning the championship. During his time in the IMSA Series he had also become the 1996 Peruvian Formula Three champion and took part in several Formula Atlantic races.

Auberlen mentioned in a 2020 edition of the Marshall Pruett Podcast that he was in advanced negotiations with Hogan Racing for a drive in the 1998 CART series but chose to pursue an opportunity with BMW instead.^[2]

Other competitions Auberlen has competed in during his career include the 24 Hours of Le Mans and the American Le Mans Series (1999-2003), driving a BMW V12 LMR in 1999 and 2000 for Schnitzer Motorsport. During the Petit Le Mans at Road Atlanta in 2000, his BMW did a spectacular back flip^[3] over the same hump over which Yannick Dalmas backflipped in a Porsche 911 GT1 in 1998.

Auberlen briefly stepped up to Grand-Am's Daytona Prototype class in 2003, in addition to driving a BMW 325i for Turner Motorsport in World Challenge touring. Auberlen won both the 2003 and 2004 Speed World Challenge Touring Car Championship behind the wheel of a Turner Motorsport BMW 325i. By doing so, Auberlen ended an eight-year Honda / Acura domination of the series.

For 2004, Auberlen dedicated himself to the production-based World Challenge GT class for BMW Motorsport's Prototype Technology Group team, earning the series championship for BMW.

In 2005, Auberlen continued to drive for BMW PTG in Grand-Am's GT series, while also driving for Panoz Racing in IMSA's American Le Mans Series.

In 2006, Auberlen once again exclusively drove BMWs — an M3 for Sigalsport's Grand-Am GT team, an M3 for Turner's Grand-Am team and an M3 for BMW PTG's ALMS team.

It is believed that Bill Auberlen has driven BMW cars in more races than any other driver in the world. He has won six professional auto-racing championships, four with BMW power. He has competed in over 500 professional races to date, 339 in BMWs. His results include 91 race victories, 188 podium finishes, 56 pole positions, 83 fastest race laps and 110 records.

For four seasons (2014-2017), Auberlen drove full-time for Rahal Letterman Lanigan Racing in the IMSA GTLM class of the WeatherTech SportsCar Championship; first in a BMW Z4 GTE then BMW M6 GTLM. In November 2017, Auberlen was named a BMW Brand Ambassador, but stepped down as a full-time driver in GTLM for 2018.^[4] He continued to compete part-time for RLLR in the endurance races, while driving for Turner Motorsports in the IMSA GTD class in shorter events, driving a BMW M6 GT3.

In 2019, Auberlen returned to full-time competition for BMW, partnering with Robby Foley in the Turner BMW #96 in the GTD class.^[5]

In addition to his racing success, Auberlen has designed and built fast boats and bikes. Using motorsport technology, he developed X Power Drive, a high-performance boating outdrive, engineered a custom 1554-hp Chevrolet engine that powered his open-bow Carrera catamaran to numerous world speed and acceleration records. He also built a custom turbocharged 420 hp motorcycle.
