This car was built for the 1967 Indy 500. It was designed by Jim Hurtubise, the chassis was welded by Bill Henderson, the body was formed by Paul Cozard and the engine was prepared by Don Shepard.
He qualified for the 1967 race at 162.411 mph, but was later bumped and missed the race.
In 1968, despite suffering engine problems throughout the month of May, Hurtubise qualified the Mallard for the Mallard for the Indy 500 in 30th position with a speed of 162.191. Hurtubise completed nine laps before a burned piston put him out of the race. This was the last time a front engine car would ever qualify for the Indy 500.
On July 6, 1968, Hurtubise set a Worlds Closed Course record at Daytona International Speedway with the Mallard running a lap at 191.938 mph.
On September 5, 1970 Hurtubise qualified the Mallard for the inaugural Ontario 500 at Ontario (CA) Motor Speedway. He lasted only one lap before hitting the wall and dropping out of the race.
Hurtubise continued to bring the Mallard to Indy each May, however, It became increasingly more difficult to remain competitive each succeeding year.
In 1972 Hurtubise qualified a rear-engine car for the 500 but still practiced with the Mallard. On the last day of time trials, the Mallard was rolled into the qualifying line. When the gun went off the signify the end of time trials the Mallard was still in line and Hurtubise opened the hood to reveal, not an engine, but five cases of Miller beer (his sponsor) all iced down and ready to be consumed.
The Mallard continued to be entered by Hurtubise at Indy through 1981 and was wildly cheered by fans at the Speedway every time Herk rolled it out for some practice laps.
