SAO PAULO — One of the most enthralling seasons of racing in recent memory finished with one of the most exciting races ever. Surely, Formula One cannot get much better than in 2012. Our hearts surely wouldn't stand it. But next year could be special, too. Unpredictable to the last lap. Competitive. Largely fair. With a deserving champion, Sebastian Vettel, pushed to his limits by a noble loser, Fernando Alonso, who might have finished as the 2012 champion himself with just a smidgen more luck. This year, F1 delivered everything one can reasonably expect from sport, and all at dizzying speed. Ridiculously expensive and gas guzzling, F1 may seem like an anachronism at a time when governments and families are counting pennies and cutting back. But, wow, what a show. With 20 races from March to November, this was the longest season in 62 years of F1. But it never felt overlong, because the outcome remained so uncertain. The tension of not being able to be sure who would finish as champion built up nicely through the year, becoming exquisite by the last race in Brazil Sunday, where only Vettel and Alonso remained in the chase for the world title. Seven different winners in the first seven races made this a year of exceptional variety. Having been so dominant last year, greedily winning 11 of 19 races, Vettel didn't really get his nose ahead this year until the F1 circus swung in September and October through Asia, where he won four successive races in Singapore, Japan, Korea and India. To the end, Alonso was on Vettel's tail. After thousands of kilometers of racing around the world in 19 different countries, the gap between them at the checkered flag at Interlagos Sunday had withered to just three points, in Vettel's favor — 281 to Alonso's 278. The Spaniard climbed out of his bright red Ferrari and stared long and hard down the track with blank, faraway eyes. Had he won that last race in Sao Paulo, instead of finishing second, or had his German rival finished just two spots lower than his 6th place, it would have been Alonso, not Vettel, being crowned as a three-time world champion and the Red Bull driver painfully ruing what might have been. But of the two drivers, Alonso was most impressive in 2012, because he made his Ferrari seem far quicker than it was. From the day in February when heavy snow at its factory in Maranello, Italy, forced Ferrari to cancel the unveiling of its F2012 model, so little this year went to plan for the most famous team in F1. The car looked a dud in preseason testing. That Alonso got to Brazil trailing Vettel by just 13 points was testimony both to his skill in squeezing every last drop of performance out of the car and Ferrari's relentless work improving it as the season progressed. The car's fundamental problems were also why Alonso hoped for a chaotic race in Brazil, because he knew his Ferrari had less chance of unsettling Vettel's superior Red Bull in a run-of-the-mill Grand Prix. Alonso got his wish, and more and the wacky race surely aged him. “The most difficult race we faced,” Vettel said. But it was edge-of-your-seat entertainment for spectators. “The most exciting race that I ever saw in Formula One,” said Nelson Piquet, F1's champion in 1981, 1983 and 1987. One of the most visible differences in the cars next year will be purely aesthetic: They'll be allowed to hide the kinks on their noses that were so ugly in 2012. Wonder-designer Adrian Newey will be looked to, to deliver another quick Red Bull, further refining his RB-series car that gave Vettel the platform to become the first driver since Michael Schumacher to win three successive world titles. Schumacher will be back in retirement, after three ho-hum years at Mercedes where he didn't get even within sniffing distance of being able to challenge for an eighth world title. His replacement is Lewis Hamilton, the Briton with a fragile temperament so keen to add to his world title of 2008. The pressure will be on Mercedes to give Hamilton a better car than its slug of 2012, so he doesn't quickly get frustrated and regret his move from McLaren. At McLaren, 2009 world champion Jenson Button is licking his lips at the idea of now leading that team. Button won Sunday's race, with what looked like speed to spare. “To end on a high is fantastic and it bodes very well for 2013,” Button said. Ferrari also is already working on its car for 2013. It hasn't had a championship driver since Kimi Raikkonen in 2007 and hasn't been able to deliver Alonso the third world title his talent surely deserves. “We need to build a quicker car,” Ferrari chassis director Pat Fry said. The biggest downer? That the next race isn't until March, in Melbourne. — AP
