Mabellini finished third overall in both the Junior ERC and ERC4 championships this year whilst driving a Toksport-prepared Renault Clio Rally4.
The 23-year-old previously told FIAERC.com about his hopes to graduate into the championship’s top-level category in 2023 and, while his plans for next season remain unconfirmed, Mabellini’s latest announcement links him with championship-winning squad Team MRF Tyres.
Rally del Brunello is a one-day gravel event based in Montalcino - and Mabellini took to social media to confirm he will contest the fixture with an MRF-backed Fabia alongside co-driver Virginia Lenzi.
