Oil pressure to blame for Kvyat retirement - Red Bull

Red Bull have completed an investigation into why Daniil Kvyat failed to start the Australian Grand Prix after he was unable to select a gear on the way to the grid.

The team had initially blamed the Renault power unit, which it thought was vibrating, damaging the gearbox. However an investigation into the exact cause back at their Milton Keynes factory identified a drop in a oil pressure.

"After investigating post-race, we found that the reason Daniil's gearbox overheated and was unable to select a gear on the way to the grid was due to a lack of oil pressure," said chief engineer Paul Monaghan.

He is confident the issue won't strike again: "As a factory we have been working hard to make sure it doesn't happen again.

"Last year the progress we made from the third test to the first race was significant and one of our strengths is our development rate.

"We have the best team in place to repeat our success and we are working as hard as we can to improve as much as possible ahead of Malaysia."
