Here’s the news from Sky Sports News;
Red Bull are flying out a new chassis for the final two days in Barcelona armed with a series of high-profile and critical upgrades as the testing season goes into dramatic overdrive.
Sky Sports F1 understands that the World Champion’s aggressive new package will include a new rear wing, a new front wing and a heavily-revised exhaust.
The revisions are so extensive that the team have had to bolt them onto a new chassis after round-the-clock work at their Milton Keynes HQ. The ‘new car’ is being flown out overnight, with Team Principal Christian Horner and Chief Designer Adrian Newey, conspicuous by their absence at the Circuit de Catalunya on the opening two days of the third-and-final winter, also flying out from England.
