Indianapolis 500 will be wide open

INDIANAPOLIS -- If more than a hundred years of history at Indianapolis Motor Speedway has taught us anything, it's that you can rarely predict the winner of the Indianapolis 500 (Sunday, noon ET, ABC).

Pick a winner four days out? Shoot, some years it's impossible to pick a winner four laps from the finish.

In 1912, Ralph De Palma led the second-ever Indianapolis 500 from Lap 2 to Lap 198 and had a 5½-lap margin on the field. But he didn't win.

Just last year, JR Hildebrand had an eight-second lead over Dan Wheldon three-quarters of the way around the 200th and final lap. Hildebrand learned the hard way that getting 799 out of 800 corners right during the 500 doesn't add up to victory. His last-lap crash was a $3 million mistake that left the late Wheldon crying tears of joy and chugging the traditional winner's milk.

Prognosticating this year's Memorial Day Classic is even more difficult than usual because there's been a wholesale equipment changeover. The chassis is still an Italian-made Dallara, but engines were downsized from 3.5 liters to 2.2 liters and turbocharged.

There's also competition between multiple engine manufacturers in the Izod IndyCar Series for the first time in six years, but for the most part, the 2012 engine war has been no contest. With a big helping hand from Team Penske, Chevrolet won the first four races of the season and powered Will Power to a comfortable championship lead over his teammate (and three-time Indy 500 winner) Helio Castroneves.

Meanwhile, the Honda camp, and especially flagship team Ganassi Racing, has struggled. The fastest Honda runner throughout Indy's nine days of practice and qualifying was rookie Josef Newgarden of local favorite Sarah Fisher Hartman Racing. The Honda cars have been more competitive in race trim, but a Chevy victory on Sunday is perhaps the safest prediction one could make this month.

Ryan Briscoe emerged from the shadow of his teammates to take pole position, the record 17th at Indianapolis for team owner Roger Penske. A victory on Sunday would be the 16th for Penske, also a record.

But an equally strong 1-2-3 threat comes from the five-car Andretti Autosport effort, which qualified 2-3-4 with drivers James Hinchcliffe, Ryan Hunter-Reay and Marco Andretti.

Hinchcliffe, a 27-year-old Toronto native who is driving the GoDaddy-sponsored car made famous by Danica Patrick, is having a breakout campaign and triumphing at Indianapolis would significantly accelerate his rise to stardom. And there's no question that a win for Marco, son of Michael and grandson of Mario Andretti, would be a huge boost for the sport of IndyCar racing as a whole.

Meanwhile, the Target Ganassi team of Scott Dixon and Dario Franchitti that has dominated the 500 the past four years, winning in 2008 and '09, has been flat all month, not even keeping pace with smaller Honda teams.

But at 500 miles, Indianapolis is almost twice as long as any other IndyCar Series race. It's also the first oval race for the new turbocharged engine formula. With engines designed for an 1,800-mile lifespan, reliability shouldn't be a problem, but engineers from Chevrolet, Honda and backmarker Lotus won't rest easy until the checkered flag falls.

The racing itself is another venture into the unknown; the DW12 chassis, with its rear wheels semi-enclosed by bodywork for safety reasons, creates a huge aerodynamic draft, or tow, in its wake. Drivers have noted substantially greater closing speeds in the turns and predict much more passing and jockeying for position than in recent years.

The last wild card is what is forecast to be searing heat and humidity, with temperatures expected to crest in the upper 90s. A real endurance test for (wo)man and machine, in other words.

It all adds up to what many observers are calling the most wide-open Indianapolis 500 in 20 to 30 years. Here's a breakdown of the 33 competitors set to contest Sunday's race (car number/sponsor/team/engine):
