Staying grounded: Castroneves knows goal of IndyCar changes
FORT WORTH, Texas (AP) Helio Castroneves has no desire in being airborne and upside down again at Indianapolis. Neither does IndyCar, which is making changes in hopes of preventing those kinds of scary flips at high-speed tracks.
''For safety, that's what we're looking at,'' Castroneves said during testing Tuesday in Texas that included curved plates affixed to the bottom of cars to help prevent them from flying into the air after spins. ''It doesn't matter what car it is.''
Those domed skid plates are among significant changes the IndyCar Series has made since last year, when Castroneves, Josef Newgarden and Ed Carpenter - all driving Chevrolets - went airborne in separate incidents at the Brickyard leading up to the Indianapolis 500 last May.
There have also been the additions of NASCAR-looking flaps behind the chassis and more tethers to keep pieces from flying off the car, like what happened at Pocono last August when British driver Justin Wilson was struck in the head by debris and died the following day.
Castroneves, Newgarden and Carpenter were among 15 drivers from five teams who took part in a day-long test at Texas Motor Speedway. There had been previous tests at California and Indianapolis with the curved plates that add downforce and help keep cars grounded if they get sideways.
Honda drivers have complained that those domed skid plates, which also raise the car, make their cars difficult to handle.
''They make a difference. My car is like pretty loose here today, it was really loose at testing in Indy,'' Graham Rahal said of his Honda. ''It definitely affects my car a lot.''
Even though the 1 1/2-mile high-banked Texas track is different than the 2 1/2-mile layup at Indianapolis, Castroneves said teams will benefit in Indy from the testing in the Lone Star State with the same aero package.
''I don't think it's that big of a deal,'' Carpenter said of the added domed skids. ''I think it's just something our competitors really like to talk and complain about.''
Newgarden, sitting next his teammate and team co-owner, responded, ''I agree.''
Rahal said he hates that domed skids have become a topic of conversation leading up to the 100th running of the Indianapolis 500 later this month.
''We should just be talking about how great the Indy 500 is. Instead, we're talking about domed skids, which nobody even knows what the heck that is other than us,'' Rahal said. ''But it does affect the car, and we're going to have work hard to make up for it.'''
Marco Andretti and Ryan Hunter-Reay, two other Honda drivers testing in Texas, never appeared as expected at the media session during the midday break.
Along with changes made before last year's Indy 500, IndyCar mandated the use of closure panels on the rear wheel guards for the remaining three superspeedway races of 2015. Those panels were first used at Texas, and later at California and Pocono Raceway.
Scott Dixon had a dominating run at Texas in June, winning by 7.8 seconds over teammate Tony Kanaan in the fastest IndyCar race ever at the track. Dixon led 97 of the 248 laps in his Chevy with an average speed of 191.940 mph in an accident-free race that had only two cautions.
Dixon pointed out that the domed skids aren't new to IndyCar. The feature was part of past generations of the cars, and last used in 2011.
''You've got to look how much greater it is for the safety side of things. ... You can't ignore that,'' Dixon said. ''Yes, it's going to be more difficult to drive, but you have a right foot and you have a team to try and work out the differences. Whether it affects one manufacturer more than the other is yet to be seen.''
