Red Bull Racing has confirmed that it will replace the Renault engine in Mark Webber's car ahead of qualifying for the Belgian Grand Prix. The team had fitted a brand new power unit to Webber's RB5 car on Saturday morning, but a problem with it was detected early in the session.

A decision was taken for a fresh Renault to be brought into play for the rest of the weekend, which will be the seventh new engine out of a total of eight that Webber has used this season. Team principal Christian Horner said it was too early to judge whether or not the problem engine this morning had a terminal problem, or if it was something that could be fixed so the unit could be brought back into action later this year.
