Morbidelli drove a Lamborghini in several grand tourer races in 2005, and moved back to touring cars for 2006. Competing in the World Touring Car Championship for N-Technology, he managed two second places in an Alfa Romeo 156. Not as competitive as when he was driving the BMW, he moved back to GT racing for 2007, winning two races in the ADAC GT Masters series. He has had considerable success in the Italian Superstars Championship, where Morbidelli won the title with both Audi RS4 and BMW M3 three years in a row from 2007. The short-lived Speedcar Series gave him another championship title, where he won the 2008–09 championship. The season featured a close fight with defending champion Johnny Herbert, with Morbidelli finishing one place ahead in the final round to win the title.
