Red Bull have denied suggestions that the world drivers' champion Sebastian Vettel's early season struggles have been due to his car having a crooked chassis.
The 26-year-old German was given a 'new' chassis for last weekend's Spanish Grand Prix in Barcelona and charged to fourth despite starting 15th following a five-place penalty for a gearbox change.
Media reports in Germany have suggested the previous chassis was crooked but the team said there was no evidence of that.
Vettel, the winner of the last four championships and the final nine races of 2013, has been fighting more for points than podiums so far this year, and he's complained of a lack of 'feel' from the car.
