Red Bull Racing's up-and-down season continued with Mark Webber and David Coulthard narrowly missing out on points in Hungary, but the team is hopeful of bouncing back to its Nurburgring form when the campaign resumes in Istanbul this weekend.

The team has been hard at work preparing for the Turkish event, even finding time to defy the test ban and get some running under its belt in an effort to ensure its cars are reliable.

"Unlike many of the other teams, we have been running during the summer break, with an aero test and a shakedown before sending the cars to Istanbul," Renault engine guru Fabrice Lom confirmed, "That allowed us to calibrate some components ahead of the weekend, and to be in a position to get the most out of our package."

It's not only Istanbul Park that is playing on RBR's mind, with the next three races all under the microscope duwing its Turkish preparations.

"We are preparing for three very demanding races for the engines, with Istanbul, Monza and Spa," Lom revealed, "Each circuit is challenging in its own way. In Turkey, there are a number of long straights, which means long periods spent at full throttle - which is always a challenge.

"Secondly, there is a fine dust all round the circuit, and that can pollute the engine unless precautions are taken. Finally, the temperatures are generally very high, which must be taken into account when planning how to run the engine. All of that makes the Turkish Grand Prix an interesting challenge for our engine team.

"However, we don't have any particular worries. At this stage of the season, we know the engine well, and its reliability has already been well tested. The drivers want a tractable, powerful and reliable engine at Istanbul, and the RS27 meets those criteria. We should be able to perform strongly this weekend and, of course, will be doing our maximum to achieve that."
