He added that more changes might be on the way with the series looking at the possibility of introducing standing starts later in the year.
Other regulations announced at the ongoing State of IndyCar summit in Indianapolis include a ten-place grid penalty for any car that has an unapproved engine change for a unit failure or team decision to switch units as a precaution.
It was also confirmed at the summit that this year's cars will not have any sort of KERS energy recovery system, but that they will have anti-stall measures. Rev limiters will be set for 12,000 rpm with the electronic control unit preventing any over-revving during an event, and there will be an initial ban on the use of an "overtake" button at least for the start of the 2012 season while the new cars and engines bed in. The engines will have a projected target life of 1850 miles per unit.
It was also announced that the new 2012 IndyCar had now passed all the FIA crash tests of November 2010 (when the car specification was signed off) and that the expectation was of speeds of up to 2mph faster on road and street courses than the comparable 2011 times, although it still appears that the DW12 is slower than ideal on ovals and is struggling to reach speeds in the area of 225mph at Indianapolis.
