In 2009 Filippi competed in the European KF3 championship where he finished 40th in a Vortex powered Tony Kart.

After six years of karting John Filippi made is autoracing debut in 2007 at Circuit Paul Armagnac.

The Corsican was entered by Equipe Palmyr in the amateur Single-seater V de V Challenge driving a Tatuus FR2000.

On March 19, 2014 it was announced that John Filippi would race in the World Touring Car Championship.

In Thailand, it was much the same story with a strong qualifying but a Race 1 incident with Tiago Monteiro forced him to retire once again.

Filippi is currently the youngest driver ever to have started from pole position in a WTCC race at 20 years and 331 days old.

It was also announced that 4-time world champion Yvan Muller would be accompanying Filippi as a driver coach for the season.
