NASCAR drivers aren’t typically keen on making jokes regarding their sponsors, understandable given the corporate and PR oversight dictating such partnerships. Still, Matt Kenseth couldn’t help himself when thanking his sponsors at the 2011 NASCAR Awards Banquet, including toilet parts brand Fluidmaster.

“Glad we finished No. 1 in that car instead of No. 2,” Kenseth said. With the crowd remaining silent, he followed up with, “I didn’t think anyone would get that joke.”

Despite Kenseth’s joke falling flat, he was undoubtedly pleased during his time in his 2011 Roush Fenway Fluidmaster Ford Fusion. It may have only run once, making it a one-hit wonder, but as Kenseth noted, it earned the No. 1 spot in its only race.

Kenseth’s No. 17 red and green Fluidmaster Ford competed at the 2011 Bank of America 500, the second race at Charlotte Motor Speedway that season and the fifth race in the Chase for the Sprint Cup.

Kenseth, who entered the race fifth in the Chase standings, qualified second for the race.

Fellow Roush Fenway driver Greg Biffle had the car to beat early and led 68 of the first 128 laps. However, Biffle lost a lap to replace a missing lug nut (he later crashed with 35 laps to go with a flat tire after contacting the wall). Kenseth took over the lead a few laps later, but on lap 200 Kyle Busch took over the top spot and maintained his lead for the next 110 laps. This included a restart with 36 and 31 laps to go. Kenseth started fourth on both occasions, and with 28 laps to go Kenseth began to reel in Busch for the top spot. “Dirty air” had been on the lips of many that weekend, but Kenseth maneuvered under Busch coming out of the fourth turn with 26 laps to go to take the lead.

Jimmie Johnson and Ryan Newman were battling with 18 laps to go when Johnson lost grip and eventually made hard contact with the outside wall, bringing out another late caution. Racing resumed with 12 laps to go with Kenseth getting the outside edge on the restart over Busch. That restart proved to be Busch’s final hopes of reclaiming the lead as Kenseth maintained about a second lead in the final laps to claim the win and do some doughnuts (or, swirlies?) on the frontstretch.

The Bank of America 500 win marked Kenseth’s third victory of the year. He snapped a 76-race winless streak early in the year at Texas and, after four consecutive finishes outside the top-20, won again at Dover.

Though the win propelled Kenseth to third in the Chase standings, just seven points behind Carl Edwards, the Cambridge, Wisconsin, driver followed his win with an 18^th and Talladega and 31^st at Martinsville. Though Kenseth finished the season with two top-fives in the final three races, a 34^th at Phoenix in which he won the pole but crashed after being hit from behind by Brian Vickers, the No. 17 settled for a fourth in the final Chase standings. That year marked Tony Stewart’s incredible run of five wins in the playoffs, which earned him the tiebreaker over Carl Edwards for the 2011 Cup title.

Kenseth’s 2011 Fluidmaster ride was only made in 1/24 scale and, after the Raced Win version DNP’d, only available in the ARC line. The production run included 936 examples, though finding one of these Kenseth rides isn’t easy or relatively cheap. The 2011 Fluidmaster Fusion regularly hovers well above the $100 mark when sold. For example, one sold on eBay in June for $149, while another buyer got a comparatively good deal in August with another model selling for $87.

Though it wasn’t made in 1/64 scale, plenty of custom makers have recreated the Fluidmaster scheme. One example sold on eBay in September for $35.
