Jerez: Red Bull have unveiled the car they hope Sebastian Vettel will steer to a fifth consecutive Formula One world championship, adapting to a major switch to six-cylinder engines.
Four-time defending world champion Vettel and new teammate Daniel Ricciardo pulled the tarp off the RB10 on Tuesday at the Jerez circuit, just before the start of preseason testing on Tuesday. They then posed for photos with team boss Christian Horner and chief designer Adrian Newey.
F1 tweaks the rules governing the engineering of cars each season, but this year's changes have required a major change in design. That has led to speculation Red Bull may have trouble to extend its four-year dominance of the competition, which last year saw Vettel match Michael Schumacher's record of 13 wins in one season as he cruised to the title.
