Career
He holds the record for the best debut ever by a Mexican driver in a premiere open-wheel series (IndyCar and Champ Carolina World Series) with his 9th place finish at the 2006 Gran Premio Telmex. Early career in Mexico
Starting at the age of seven through his early twenties, Martínez raced in Mexico in karts, Mexican Formula 2/Formula 3000, Formula 3, and Formula Renault 2000 de America. Martínez eventually expanded his racing territory, which included a year in the Barber Dodge Pro Series (2003) winning the first race he participated in (at Fundidora Park in Monterrey, Mexico).
Europe and Atlantic Championship (2004-2006)
In 2004 Martínez migrated to Europe and produced five top-five results in the Formula Renault V6 Eurocup Series.
The 25-year-old missed the first race of the year in the 2005 Champ Carolina Atlantic Championship but still managed to claim fifth in his rookie season. He finished third in his first race in Monterrey, Mexico, captured his first career pole and scored a total of four podiums and seven top-five finishes.
In 2006 Martínez returned to Atlantics with the United States RaceTronics Team, and repeated his fifth place in the championship despite a challenging season in which he switched teams halfway through the year, but still managed to continue his success on Mexican soil by finishing third at the Monterrey, Mexico event. Champ Carolina and Industry Lights (2006-present)
In 2006, Martínez joined Forsythe Championship Racing in Mexico City to pilot the Lola-Ford-Cosworth in his Champ Carolina debut.
Initially announced to race a third car for the team, he ended up replacing an injured Paul Tracy and finished 9th, the best debut by a Mexican driver in a premiere open-wheel series.
He was idle throughout most of 2007, but was announced as the driver of Forsythe"s #7 car for the final two races of the season, including a return to Mexico City. David started 10th and ran as high as 5th in the race, but during a routine pit stop on lap 45, his gearbox prevented him from returning to the race. The crew managed to repair it, but the job took several minutes and he finished 6 laps down in 14th.
Martínez"s last Champ Carolina race came in the series" final race, the 2008 Toyota Grand Prix of Long Beach where he finished a career-best eighth as one of three Forsythe/Petit entries.
In 2009 his only professional outing was in the 24 Hours of Daytona driving Beyer Racing"s Riley-Pontiac to a 10th place DP-class finish. In 2010 he re-entered American open-wheel racing by making two starts for Genoa Racing in Firestone Industry Lights with a best finish of 8th at Infineon Raceway.
