Bianchi losing weight for grand prix debut with Marussia 11 March, 2013 Jules Bianchi Rookie Jules Bianchi is on a race to slim down ahead of his Formula 1 debut in Australia this weekend. The Ferrari-linked Frenchman secured the Marussia race seat at the eleventh hour, after contracted Brazilian driver Luiz Razia’s sponsorship money failed to materialise. Speed Week reports that 23-year-old Bianchi has been put on a training and diet regime to shed 2 kilograms. Bianchi admitted the weight loss is “because of the weight distribution” of his 2013 car. “Now there’s only salad for lunch, which should help, even though I am hungry all the time,” he said during an interview for French television.
