             === More technical problems for Red Bull in Jerez ===
 Jerez,  Spain  ( - Red Bull  endured a third straight day of
 technical issues with its 2014 car, the RB10, in Formula One preseason testing
 on Thursday in Jerez.
 Having  won the  F1 constructors' championship the past four seasons, Red Bull
 was  once again  forced to  have  its test  session cut  short to  investigate
 problems  with the  car, particularly  the  engine. On  Wednesday, Red  Bull's
 engine supplier, Renault, reported an energy store issue.
 Four-time  defending F1  world champion Sebastian Vettel drove the RB10 during
 the  first two days  of testing. Daniel Ricciardo, a newcomer to the team, was
 behind  the wheel  of the car on day  three and scheduled for the final day on
 Friday.  Ricciardo went on track for the first time midway through the session
 but  failed to  complete a lap when the  car came to a halt after smoke plumed
 from the back of it.
 After  extensive work on the car, Ricciardo returned to complete only two laps
 when  Red Bull opted to curtail its session and further investigate the matter
 to ready the car for Friday.
 "We  worked hard  yesterday to make the  changes it was felt were necessary to
 overcome  the problems we identified, and we were hopeful of a more successful
 day  today," said  Red Bull  race engineer  Andy Damerum.  "Unfortunately, the
 measures  we took only partially solved the issue and, as with yesterday, it's
 more sensible to stop and dig deeper into finding a solution.
 "It's  obviously not  where we  want to  be and  naturally the  whole team  is
 frustrated  by these  issues. However, we're pretty good at bouncing back from
 this  type of thing. This is where the whole team pulls together, and I'm sure
 we will get these problems fixed."
 Red Bull's RB10 has been on track for a total of just 14 laps during the first
 three  days  of testing.  Vettel made three  laps on Tuesday  and eight on the
 following day.
 Rookie  Kevin Magnussen from McLaren posted the quickest lap time of 1 minute,
 23.276  seconds during  the session. It's the  second day in a row McLaren has
 topped  the  time charts. Magnussen's  teammate, Jenson Button, was fastest on
