Red Bull troubles continue in Bahrain

Red Bull's 2014 troubles continued on the first day of the second pre-season test in Bahrain. The world champions, whose first test was disastrous, completed just 14 laps with Sebastian Vettel at the wheel. Red Bull were delayed by five hours because of problems building the car. When they did start running it broke down with over one hour remaining. Force India's Nico Hulkenberg was fastest from Ferrari's Fernando Alonso and Mercedes' Lewis Hamilton. McLaren's Kevin Maussen was fourth quickest from Vettel, who was 3.344secs off the pace. It is not yet clear what caused the Red Bull to stop on track but there was a burning smell coming from the car when it was returned to the pits on the back of a lorry. Red Bull have brought two different bodywork packages to Bahrain in an attempt to find a solution to the chronic overheating that, along with severe problems with the Renault power-unit, caused their troubles at the first test. "Obviously we're not happy with where we are right now but we still have a long way ahead of us," said Vettel. "It's difficult to judge where we are. I haven't had much of the car yet. The first gut feeling is OK but we need more to judge the car. It is not that easy to find a quick fix. I think we understand the problems but it's not easy to find a solution. "We had a problem with temperature in Jerez which we seemed to fix, at least with the couple of laps we could do. But very often you fix one problem and another one pops up."
