The IZOD IndyCar Series announced on Monday that it has updated its rules regarding engine changes. The changes address power plant failures that occur during an on-track test. According to Rule 15.5.8 (approved engine change outs), an engine may be changed without a penalty when it fails during a team test, a rookie test, an engine manufacturer test or a straight-line test.
However, the rule does not apply to engine failures at upcoming open tests. Engines failing during these tests will be subject to another rule that pertains to unapproved engine change-outs at the Pocono Raceway on July 4, at the Mid-Ohio Sports Car Course on July 31 and at the Sonoma Raceway on August 21. Rule 15.6 (unapproved engine change outs) will be the governing rule during these one-day activities.
