The initial entry list for the Indianapolis 500 features a total of 40 cars set to fight for the 33 grid positions.
That tally is one more than the initial entry last year, despite the regular IndyCar Series field shrinking from 26 to 22 cars amid the financial downturn.
Several of the full-time teams are adding extra cars for Indy, with the highest-profile being Paul Tracy's return to the 500 with KV Racing. The team has also submitted a third entry for an unidentified driver to join Tracy and regular driver Mario Moraes.
Penske's #12 car will make what is currently its last scheduled appearance of 2009 with Will Power, who had to step down from the full-time #3 car when Helio Castroneves was acquitted in his tax evasion trial last weekend.
Although it has been unable to fund a full-season programme, Rahal Letterman Racing will run one car for Indianapolis, with Roth Racing also making a comeback with a two-car Indy entry.
Former driver Bryan Herta's new Bryan Herta Autosport Indy Lights team is to attempt to make its IndyCar debut at the 500, running a single car in conjunction with Vision Racing.
Also running an additional car in collaboration with a well-known name is Dreyer & Reinbold, which is entering John Andretti in association with Richard Petty Motorsports. The D&R squad is set to bring four entries in total to Indianapolis, with Andretti, Davey Hamilton and one other - possibly Milka Duno - joining team regular Mike Conway.
Ganassi protege Alex Lloyd will make a second attempt at Indy, this time run by 500 regular and Indy Lights front-runner Sam Schmidt Motorsports.
Other teams adding additional cars for Indianapolis are Panther with former 500 pole-winner Scott Sharp, Conquest, AJ Foyt Enterprises - where AJ Foyt IV is returning after losing his Vision drive - and Dale Coyne Racing, while Hemelgarn Racing will make its usual Indy run and part-time owner/driver Sarah Fisher will enter a second car alongside her own.
