Williams expects trial by sand

Despite the high level of computer-based circuit simulation available to F1 teams, Michael admits there are still plenty of unknowns that could trip Williams up in the middle eastern desert - despite the fact test driver Marc Gene completed a handful of laps there recently.

"Strategy may prove different to the trend of three short stint pitstops we've seen in recent races because we have no information on the amount of time we'll lose in the pitlane, tyre degradation or what the fuel penalty will be," said Michael. "The inaugural Bahrain Grand Prix will pose plenty of challenges that we have not faced before. In particular, the area is surrounded by fine, coral sand that can cause many operational and on-board mechanical problems. Hopefully there won't be any sand storms, not least because the paint work on the cars will definitely take a battering in these conditions."

Although encouraged by the team's Malaysian Grand Prix performance, Michael cites many other variables that will have a big effect.

"We have made some minor improvements to the car since the Malaysian Grand Prix where we were competitive during the race, although not competitive enough to win," he added. "Michelin will bring two known tyre choices as they did for the last race, being a new circuit the compound choice will be interesting.

"From the circuit layout, the track seems to be quite twisty with predominantly slow speed corners but there are three straight sections that may offer overtaking opportunities. Judging by the shape of the first corner, the start of the race could be interesting."
