Red Bull confirms new chassis for Sebastian Vettel

The four-time Formula 1 World Champion has had a difficult start to the 2014 F1 season and following the Chinese Grand Prix last month, Red Bull adviser, Helmut Marko speculated that it might be because of a fault with the chassis. However, Marshal has said Vettel was always scheduled to get a new tub for Barcelona.

"Sebastian will get a new chassis for Barcelona, which was scheduled at the start of the season and then the next one will be for Daniel [Ricciardo] at some time around Silverstone," Marshal told Red Bull's official website site.

Asked if the new chassis will be of advantage to Vettel, Marshal replied: "It shouldn't be, as the idea is that they are all the same. Drivers don't always want to change them – they can get attached to a particular chassis and when they are on a good run they like to hang on to it for as long as possible!"

"Normally we make four or five chassis during the year, maybe six, so it wouldn't be unusual for each driver to change at least once or twice during the year. Normally they would use at least two," he added.
