Iannetta's motorsport roots trace back to the early 1990s, when he began karting in France. Between 1993 and 1998 he competed in the French Karting Championship in the Yamaha class, recording fifteen podium finishes, while also attending the ACO flying school at Le Mans. His diverse background extended beyond conventional circuit racing: from 2000 onward he worked with the automotive stunt team CINE CASCADE, directed by Jean-Claude Lagnes, performing vehicle sequences for major French and international feature films including Taxi, The Bourne Identity, Ripoux 3, and 36 Quai des Orfèvres.
Iannetta received the World Stunt Award in the United States for the best vehicle sequence of 2003, earned for his work on The Bourne Identity. Alongside his racing commitments he has served as an instructor at the flight school PRO'PULSION, with locations in Dreux and Issoire, and has worked as a launch driver for major automotive manufacturers including Volkswagen, Audi, Citroën, Renault, and Alfa Romeo, evaluating new vehicles ahead of market release.
Iannetta's circuit career began in earnest in 1999 when he entered the French Formula Renault Elf Campus series and won the ten-hour Soucy Karting event. The following year he placed fifth in the French Formula Ford Promotion Championship, claiming three podiums.
His breakthrough at single-seater level came in 2002, when he became Champion of the French Formula Ford Promotion class with eight wins from nine races, while simultaneously finishing as vice-champion of the broader French Formula Ford series with nine podiums from nine starts. That same year he was tested by Welter Racing for potential Le Mans and Sebring entries.
From 2004 onward Iannetta transitioned primarily to GT and sports-car competition. He raced in the Spanish SEAT León Supercopa and the French Touring Car Championship in 2004. In 2005 he campaigned in the Le Mans Endurance Series with two separate teams: Noel Del Bello Racing on a Courage C65-Mecachrome and Paul Belmondo Racing on a Chrysler Viper GTS-R.
Iannetta made three starts at the 24 Hours of Le Mans. In 2005 he raced the Mecachrome Courage C65 for Team Noel Del Bello Racing. He returned in 2006, finishing sixth in the GT2 class aboard a Porsche 996 GT3-RSR for Ice Pol Racing Team while also contesting two rounds of the Le Mans Series in the same car. His third Le Mans start came in 2007, again with Noel Del Bello Racing, this time in the LMP2 category in a Courage AER. A final appearance followed in 2009 with Creation Autosportif, driving a Creation-Judd in the LMP1 class.
In 2006 Iannetta won the World Cup Fun Cup at Jarama with Optimum Racing. He also contested three rounds of the Andros Trophy ice-racing series that year on a Citroën C4 Silhouette. In 2007 he placed eighth in the Spanish SEAT León Supercopa, with three podiums and two wins, and finished fifth in the World Cup Fun Cup.
Later in his career Iannetta competed in the GT4 European Series, driving the No. 77 Audi R8 LMS GT4 Evo for Full Motorsport. He also raced part-time in the NASCAR Whelen Euro Series, contesting the EuroNASCAR PRO class in the No. 46 Chevrolet Camaro for Marko Stipp Motorsport.
Iannetta represents a rare crossover between professional motorsport and the film stunt industry, accumulating credible results at Le Mans across three different prototype and GT classes while simultaneously building a parallel career as one of France's more decorated automotive stunt performers. His family connection to the Le Mans paddock through his uncle Alain, combined with his own four appearances at the Circuit de la Sarthe, places him within a notable tradition of French endurance racing.
