Weekend review and results round-up

It was a very, very busy weekend off-track too, and it started early Thursday morning with the news that not only had Ferrari extended Fernando Alonso's contract, but that the deal now stretched right through 2016.

For the first time in a while, there was also a technical row brewing. Ferrari's new rear wing was swiftly banned on Saturday morning, but the question of whether off-throttle exhaust-blown diffusers are legal looks set to run on to Monaco, where there might even be a protest.

Expect F1 2011 to keep changing shape too. Pirelli revealed it is working towards a situation where two stops rather than the current three or four become the most sensible option, and the FIA announced that there would be two DRS zones on each track from Montreal onwards.

The main non-F1 event of the weekend was Indianapolis 500 qualiying, and in the most competitive and unpredictable Pole and Bump Days in years, underdogs Alex Tagliani and Sam Schmidt Motorsports took pole on a largely depressing weekend for the usual big guns. Ganassi rued a fuelling error, Penske lacked pace, and Andretti Autosport struggled so much that two of its cars did not even qualify.

Elsewhere in America, Kimi Raikkonen's arrival in NASCAR Trucks gathered as much attention as Carl Edwards' victory in the non-points All-Star race at Charlotte.
