Despite having just two new engines left from his season's allocation of eight, Formula One world championship contender Sebastian Vettel insists that he is not going to worry himself with the prospect of further failures.
The German, who suffered two failures over the European Grand Prix weekend alone, unsurprisingly limited his Friday running at Spa-Francorchamps, but confirmed that he will be running a fresh Renault V8 in Saturday practice, hoping to use the extra potential to secure a good grid position for the Belgian GP as he looks to prolong his title battle with Red Bull team-mate Mark Webber and Brawn twins Jenson Button and Rubens Barrichello.
"I do not expect a dramatic change, as the season so far has shown that the engine does not lose too much power with a higher mileage," Vettel, who also has just two 'used' engines available, told the official F1 website when asked whether he had any concerns about another engine change, "It should be okay tomorrow. Pole position is the aim.
"Today, the times where closer together than you would have expected at a track like Spa and, although the Brawns where a bit in the back today, they will be strong again tomorrow. Let's wait and see what happens, but clearly we want to put in a good time and bring the car to the front of the grid.
"I think today was quite okay, as I think that some of the guys in the front were running on a really low fuel load. At the end of the session we also tried to run a little lower to find out what is possible and I think that was no bad idea.
Asked whether he would be listening more carefully for any tell-tale signs of further problems, the German insisted that nothing would change in the cockpit.
"No, not really, because, if you do, then probably what you want to avoid is really happening - some sort of self-fulfilling prophecy," he reasoned, "You concentrate on running and, as long as there is a sound behind you, everything is okay."
Despite the limited running on Friday, however, Vettel remained confident that Red Bull could be a factor in both qualifying and the race.
"It was clear that I would make less laps then the others, but still I think it went well for me," he assured, "We have to see tomorrow, as you can never be exactly sure about the fuel loads used by the other teams and where you realistically are. I think this circuit suits the RB5 but, today, it was tricky to make a final statement of where we are. The gap to the Brawn looks bigger than it is in reality and my prediction for tomorrow is that it will be very close. But, again, we are in good shape and should do well in qualifying."
