What does the Hungarian Grand Prix show?

Lewis Hamilton won his first race of 2013 on Sunday at the Hungarian Grand Prix. Here's a look at five talking points from the action at the Hungaroring:

Mercedes not so tired Lewis Hamilton had written off his victory hopes after qualifying, but the new Pirelli rubber brought to Budapest clearly proved much more to his Mercedes-GP's car. He dominated the race, making passing moves, when he had to, and richly deserved his first win of 2013.

Wasted opportunity Romain Grosjean continues to frustrate. For the second successive race, he out-performed Lotus teammate Kimi Raikkonen, but what should have been at least a second-place finish was instead sixth after he clumsily hit Jenson Button's McLaren-Mercedes, earning a drive-through pit-lane penalty.

Flattering to deceive Fernando Alonso drove well to take fifth place in his Ferrari, but he was out-paced by Mercedes, Red Bull Racing and Lotus cars, and his hopes of winning a third world championship are looking unlikely at present.

Breakthrough Williams have won seven times at the Hungaroring, and on Sunday was another success for them, admittedly on a much lesser scale. The British team picked up their first championship point of the season as Pastor Maldonado finished in 10th spot.

Falling back Prior to the changes to the Pirelli tyre compounds, Force India had been on the pace, scoring 59 points in the first eight races. But their form has dropped with the changes and they had a miserable time in Hungary, with Adrian Sutil retiring and Paul di Resta the last classified runner in 18th.
