By 2005 he had added a further four world championship titles to his collection, with titles number eight and nine following in 2008 and 2009. Rossi continued to do battle for the world championship crown regularly after that. 'The Doctor' has also long been committed to youth development with his VR46 Rider Academy – a 'school' that helps young Italian riders with the goal to bring them to MotoGP. Rossi also took part in testing in various racing cars early on – including a Formula 1 Ferrari and Mercedes. There were also starts at the Monza rally (ITA) in 2009 as well as two races in the World Rally Championship, one in 2006 in New Zealand and one in 2009 in Wales. In 2019, Rossi competed in an endurance race in Abu Dhabi (UAE). After retiring from active motorcycle racing after the season finale in 2021, Rossi embarked on a new chapter of car racing. He contested the GT World Challenge Europe with Team WRT in the 2022 season. Fanatec GT World Challenge Europe Powered by AWS – 4.
