This weekend’s Iowa INDYCAR 250s will be the second straight weekend that the NTT INDYCAR SERIES will conduct doubleheader races, but the first at an oval since 2011.

There have been 10 previous oval doubleheaders in INDYCAR history, the most recent being the Firestone Twin 275s at Texas Motor Speedway in June 2011. But Iowa will be the first to host races on consecutive days.

Other oval tracks to host INDYCAR same-day doubleheaders are Langhorne Speedway (1968), Autodromo Ciudad de Rafaela (Argentina) (1971), Trenton Speedway (1973-74), Ontario Motor Speedway (1973-75) and Atlanta Motor Speedway (1979 and 1981).

Here are some Frequently Asked Questions to prepare you for the Iowa doubleheader.

What is the race distance?

Each Iowa INDYCAR 250 will be 250 laps or 218.75 miles on the 7/8-mile oval.

How will the field for each race be set?

Qualifying for the Iowa INDYCAR 250s will utilize a unique qualifying format for the first time.

NTT P1 Award qualifying will still consist of two timed laps around the 7/8-mile oval, but the first lap of single-car runs after the green flag will set the field for Friday’s first race, while the second lap -- following the white flag – will set the field for Saturday’s Race 2.

The pole winner for each race will receive the NTT P1 Award and earn a bonus point that accompanies the award.

How are points awarded?

Each race will be a full points-paying NTT INDYCAR SERIES race, with the winner earning 50 points as usual. A bonus point will be given to the NTT P1 Award winner for each race and any driver who leads a lap in either race, and two bonus points will be given to the driver that leads the most laps in each race. A driver could earn a maximum of 108 points this weekend.

How are the pits assigned?

Pits are based on entrant points entering the event. Teams with more than one car have their points averaged and are ranked by their average point total. They will not have to move their pit equipment between races.

How much track time will teams get?

There are two practice sessions this weekend. Friday’s 90-minute practice session (2 p.m. ET on NBC Sports Gold) will be open to the three rookie drivers (Oliver Askew, Alex Palou and Rinus VeeKay) and two first-time competitors (Pato O’Ward and Jack Harvey) for the first 30 minutes, then to all cars starting for the final 60 minutes. There’s a one-hour practice session Saturday (3:30 p.m. ET on NBC Sports Gold).

How much fuel/tires can drivers use?

Each driver has 14 sets of Firestone Firehawk tires to use during the race weekend and approximately 75 gallons of Speedway E85 fuel in their pit tanks for each race.
