Maxi is the older Formula 1 type racing car who was the star of Silver Hatch before Roary arrived. He is temperamental and expects the best of everything - including first use of the tyre warmers. He wears sunglasses and a blue cap and sports the number 5. Maxi is Italian and is the favourite of Mr Carburettor. Maxi's catchphrase is "Mamma Mia!" He speakes in a Mock Italian accent. When starting a race Maxi can make flames erupt from his exhaust. There is a healthy sibling-rivalry between Maxi and Roary.
