At Watkins Glen International, he qualified fourth, but moved into the lead on lap-2. After losing first place, Andretti was challenged by the points leader, Wade Cunningham, but held on to finish second by a margin of 0.6316-seconds.
The championship leader heading into the penultimate weekend at Watkins Glen International was the Kiwi Wade Cunningham. Cunningham was yet to collect a victory, but eight podium finishes in twelve starts put him at the top of the standings. He qualified on the pole for the Corning 100, his first of 2005. Cunningham lost the lead before the end of the first lap but would claim the final spot on the podium.
The Menards IRL Infiniti Pro Series requires the use of a spec motor. The engine used is from Infiniti’s Q45 model. The power plant is Nissan’s VK45DE, which is a V8 aluminum block with double-overhead-camshaft aluminum cylinder heads. The 3.5-liter race version of the motor was developed by TWR (Tom Walkinshaw Racing) and produced 420-horsepower. Fitted to the engine is a six-speed sequential transmission.
Entering the penultimate round at Watkins Glen International, Travis Gregg had five podium finishes, of which three were victories. However, the wins came on ovals and road courses weren’t his ‘strong suit.’ Gregg, driving the No. 7 Lucas Oil Products Dallara / Infiniti, was eighth fastest in the qualifying session. He spun in turn eight during the race and eventually lost two laps to leaders and finished in the twelfth position.
