Fumanelli, after just two years of national karting races, made his single-seater debut in 2008 in his native Italian Formula Renault 2.0 series, driving for RP Motorsport.

During the last event in Valencia he was involved in a violent airborne accident with Spanish driver Carmen Jordá, which resulted in a vertebra trauma which forced him to a 6 months stop.

Following a successful test at Jerez in December 2011, Fumanelli graduated to the GP3 Series in 2012, racing for MW Arden Team.

[1] His rookie season was very strong, many top-5 qualifyings brought him to a podium finish at the European GP in Valencia Street Circuit and a 4th place in Monaco Gran Prix.

Despite some very strong winter tests, the Italian duo struggled with performance during the season and they decided to split up one round to the end of the championship.

They debuted together at Bathurst 12 hours, first round of the Intercontinental GT Challenge with a Mercedes AMG GT3 finishing 3rd in Pro Am class.

He raced for Mercedes Black Falcon Team in the last round of Blancpain GT Endurance, finishing 2nd in Silver class and 7th overall.
