Fear the Mustache: The Iowa Preview

Ryan Blaney has never finished worse than fourth at Iowa. He won here in 2024 leading 201 of 350 laps and ran fourth last year. He and William Byron are the only drivers averaging inside the top 3 in the two Cup races this track has ever hosted. The sim respects the record: Blaney sits second on our table with a median finish of 6th and the most projected laps led in the field at 47.5.

So with two 24th-place finishes back to back, why is Denny Hamlin above him, first on our table? Because everywhere else, his flat-track season has been close to perfect. He won at Nashville and Pocono, ran second at Martinsville and North Wilkesboro, and took fifths at Phoenix and the Brickyard, six flat tracks without a finish worse than fifth. Experience is the honest explanation for the Iowa gap: of his 744 career starts, exactly 2 came here. Our sim ran Sunday's race 10,000 times and sided with the season, putting Hamlin first with a median finish of 5th and a 15.2% win chance, the best number in the field. Those two 24ths are the entire case against him.

Iowa itself is why nobody can be sure. It is the longest short track on the schedule at 0.875 miles, and the fastest one by a lot: the field averages 128 miles per hour here, against 117 at Bristol and 108 at Richmond. The extra length is what makes the speed. Drivers get short-track corners at speeds no other short track produces, and only two years of history exist for anybody to learn from.

The drivers who have learned it fastest make a short list. Seven hold a two-race average finish inside the top 10: Byron at 1.5, Blaney at 2.5, then Keselowski, Logano, Bowman, Elliott, and Berry. That is four Fords, three Hendrick Chevrolets, and zero Toyotas. This year, Toyota has been the class of the series, and Iowa is the one wall it has not climbed. Byron is the defending winner, and the trophy flatters the defense: he took last year's race on fuel strategy after leading 141 laps. He holds the second-best win chance at 10.2% but projects a median finish of 8th.

If a Toyota finally breaks through, the history says it will be Christopher Bell or Chase Briscoe. Toyota owns exactly two top-five finishes in Iowa's Cup history, one each year: Bell ran fourth in 2024, and Briscoe put his car on the pole last year, led 81 laps, and finished second to Byron's fuel call. That is the closest Toyota has come to winning here. Briscoe is also the driver our readers kept telling us we were underrating, and they were right. He beat our projected finish by five or more spots in each of his last three non-plate races, and this week we found out part of the reason: a data error in how our model read his car history, which we fixed Thursday morning. On the corrected table he ranks third with a median finish of 7th, one spot clear of Byron and Larson, and a 9.5% win chance. The surge was real. Our model finally sees it.

The Heat Check above measures exactly that kind of run: average finish over the last five races against the full season. Bell, Logano, Briscoe, and Gibbs all sit on its hot side, and all four project inside our top 10 this week. Shane van Gisbergen at +6.9 is the interesting name. Everybody knows the road-course record, but his four best oval finishes this season have all come at braking tracks in Iowa's class: fifth at Nashville, fifth at North Wilkesboro, and 11ths at Phoenix and Martinsville. If he qualifies well and stays out of the wrecks, a solid finish would not surprise us. Austin Cindric at +4.4 has quiet Iowa credentials of his own: he started fourth here last year and led 20 laps before finishing 12th. And Alex Bowman deserves his flowers. His season average sits around 21st and his last five average 16th. Iowa has been kind to him too, 8th and 7th in the two runnings. The cold side of the chart is making our table's argument for us. Reddick, second in the points, is the coldest driver in the field at minus 12.2, and we project him a median finish of 11th this week.

Joey Logano sits on both lists: the hot side of the chart and the seven names above. He finished sixth and ninth here and gained exactly five spots from his starting position in both races. His last three weeks went like this: ninth at Atlanta, a win at North Wilkesboro leading 323 laps, and third at the Brickyard with the race's fastest lap. The schedule is about to reward that form. Iowa, Richmond, and Loudon are three consecutive races in the same flat-track class, and four of the next six points races run on it.

There is one thing nobody has data on yet: Goodyear brings a new left-side tire to Iowa this weekend, and with practice and qualifying both compressed into Saturday afternoon, this preview is a snapshot from before anyone has turned a lap on it. The Practice Lab in Turn Four Racing Pro charts every Saturday run as it happens; that is where we will be reading the tire.

For DFS players, the shape of this race is the opposite of the Brickyard. At 350 laps, the laps-led pool is worth 87.5 DraftKings points, more than double Indy's 40, and the fastest-lap pool is bigger still, so dominators decide this slate. Blaney's 47.5 projected laps led is the biggest single number on our table, Hamlin is right behind at 44.3, and Briscoe at 31.5 comes at a friendlier salary. Saturday's practice will move all of this, and the dynamic projections page re-sims as it does.

Saturday's HyVee Perks 250 has Ross Chastain dropping down from Cup duty in a JR Motorsports car, and he tops the win odds at 19.3% with a median finish of 6th. Justin Allgaier holds the best projected finish on our O'Reilly table, a median of 5th, with an 18.2% win chance and 40.1 projected laps led. His Iowa book is the deepest in the field, eighteen starts with a 2018 win from 182 laps led. The last two visits went 30th and 16th. Sam Mayer ranks third on our O'Reilly table with a median finish of 6th and the second-most projected laps led at 29.9.

These tables are Thursday's snapshot, from a sim run before practice and qualifying. The sim keeps re-running through practice, qualifying, and driver news, right up to the green flag.
