IndyCar is set to broaden the length of its season when it releases the 2016 calendar this week.
The series received a modicum of criticism for its abbreviated schedule this year which began on the final weekend in March and finished on the final weekend of August.
Again opening with the St Petersburg street race and ending at Sonoma in California, the 2016 season promises to be more than a month longer.
The latter part of the season will be more spread out compared to the cramped ending to this year's schedule which saw a hectic finish with the final five races from July 12 to August 30.
As previously reported IndyCar will return to Road America for the first time since 2007 with Phoenix also set to make a comeback for the first time since 2005.
IndyCar has chopped Fontana and Milwaukee while New Orleans' NOLA Motorsports Park, which made its debut on the calendar this year, will also be missing from the 2016 line-up.
The full schedule will see a balance five street events, five oval races, and five events on permanent road courses.
A new street race is also ready to join next year in Boston, ahead of the final round at Sonoma.
