With little chance of rain today, there are two main factors that we must consider ahead of the Hungarian Grand Prix - three if you consider the possibility of Michael Schumacher and Juan Pablo Montoya eliminating one another at the first corner.

As ever, the first thing we must consider is strategy, with many saying that pole-man Michael Schumacher is running light and therefore on a three-stop strategy. At the post race press conference the Colombian seemed very confident, however Ross Brawn is, without doubt, the best strategist in the pitlane.

The other thing to consider is the 'Trulli factor'. It's well known that it is virtually impossible to overtake here, though we all remember that wonderful move Nigel Mansell made on Ayrton Senna - courtesy of Stefan Johansson - back in 1989. Indeed, that was the only time in the history of the Hungarian event that a driver starting outside the first five places on the grid has won the race.

The best example of how notorious this circuit is - even after its revamp - is to go back to 1990 when Thierry Boutsen made life - and overtaking - absolutely impossible for Ayrton Senna, the Belgian holding up the Brazilian for lap after lap after lap, eventually crossing the line to win by 0.288s. All the Williams driver had to do was keep his car on the line, the onus was on Senna, who as we all know was no slouch and up there with the best of them when it came to balls-out racing.

Add to this the fact that contemporary aerodynamics regulations make overtaking even more difficult that in the early 90s, and you'll understand why today's start is so important.

In recent races, Jarno Trulli has become a (high speed) mobile chicane and therefore anyone behind him at the first corner today, and that will probably include World Championship leader Fernando Alonso, can give up any hope of challenging for the win. Therefore, it's not simply about what Michael and Juan Pablo get up to at the first corner, it's about who fails to get past Trulli's Toyota.

Even before the warm-up lap there's drama, as Montoya driver over a BAR generator as he takes his place on the grid. He damages the vanes on his car but they are quickly replaced. Question is, was there any other damage?

As the drivers wait on the grid to begin the warm-up lap, the air temperature is 34 degrees C, while the track temperature is 47 degrees. It's hot!

They head off on the war-up lap, everyone getting away cleanly. Nobody is starting from the pitlane.

Michael gives it some serious 'welly', as he takes his place on the grid.

Michael makes a brilliant start as does Montoya, while Raikkonen gets ahead of Trulli and the Colombian. However, further back there's a collision which sees Klien's Red Bull somersault off the track - he appeared to touch wheels with Villeneuve.

At the end of the first lap, Barrichello and Alonso pit, having touched at the first corner, though they were not involved in the Klien incident. Sadly for the Milton Keynes team David Coulthard is also out having spun off after losing a wheel running over Alonso's wing which was in the middle of the track.
