Red Bull's speed in Spain left its rivals reeling, and this time it turned that pace into a dominant victory - at least for Mark Webber, as it was Sebastian Vettel's turn for a rocky afternoon.
Much of the news focused on tyre plans for 2011, with the teams eager for a decision by Monaco at the latest, and still optimistic of persuading Bridgestone to stay.
F-Ducts were a talking point too: Ferrari had one all weekend for the first time, but by Sunday night it was clear that no one would be running one next season...
While the Spanish Grand Prix generated slightly more excitement than Catalunya's critics had feared, the action was undeniably spectacular elsewhere in motorsport. Sebastien Loeb and Sebastien Ogier grabbed the headlines in the Rally New Zealand, but it was Jari-Matti Latvala who finally won one of the most exciting events in World Rally Championship history.
Amid chaos, changing weather and even power cuts at Spa, Peugeot won its first head to head of the year with Audi in round two of the Le Mans Series.
Pal Verhaug and Alexander Rossi will go down in history as GP3's first ever race winners, while 'big brother' class GP2 kicked off for 2010 with victories for newcomers Charles Pic and Fabio Leimer, and disappointments for the anticipated title favourites.
