INDYCAR announced that full-season IndyCar Series teams are permitted a total of 18 testing days, with the opportunity for bonus days, through the 2014 season finale at Auto Club Speedway.

The days can be used in any combination of engine manufacturer tests, team tests, Open Tests, straight line and full-sized wind tunnel tests.

“Our objective was to structure the testing rules so that everybody had equal opportunity and an equal number of days,” INDYCAR president of competition and operations Derrick Walker said. “Rather than INDYCAR designating specific numbers for each category of testing, the onus is on teams to utilize days as they feel is best for their individual program.”

Additionally, IndyCar Series teams can receive two bonus days by testing a current Indy Lights Presented by Cooper Tires driver. Teams will have two additional days for testing rookie drivers and any new entrant will have four additional offseason team test days in addition to its allotment of 18 days.

KV Racing Technology is the first on track during the initial offseason window that stretches to Dec. 20 with Sebastien Bourdais and Indy Lights competitor Mikael Grenier testing Nov. 13-14 at Sebring International Raceway. Additional drivers will be at Sebring on Nov. 18, participating in testing of the new-for-2014 twin turbo Honda engine.

Open Tests will be held at three venues that host 2014 IndyCar Series events:

• Barber Motorsports Park in Birmingham, Ala., will be the site of spring training on March 17 and March 18 for the second consecutive year. Spring training is mandatory for all Leaders Circle entrants.

• The newly modified Indianapolis Motor Speedway road course will be open on April 30 in advance of the inaugural Grand Prix of Indianapolis on May 8-10.

• The 2-mile Auto Club Speedway oval will again be the site of an Open Test on Aug. 27 in advance of the 500-mile season finale under the lights.
