#14- Max Papis - Chassis No. 14-731: This car debuted in impressive fashion last June at Sonoma Raceway as Tony Stewart took Chassis No. 14-731 from its 24th-place starting spot and rallied it to a strong second-place finish. Its second and final start of 2012 came at Watkins Glen International in August. It qualified ninth and Stewart wheeled it up to second, but on lap 71, he spun off the final corner of the 2.45-mile, 11-turn road course and backed into the Armco barrier lining the inside of pit road, sustaining heavy damage. Several trips to the pits allowed the crew the opportunity to repair the car enough to finish the race, and that’s just what Stewart did, rallying from 29th on lap 74 to finish 19th when the checkered flag dropped after lap 90. With 2013 Chevrolet SS bodywork covering it, Chassis No. 14-731 was tested May 28 at Road Atlanta in Braselton, Ga., with road-racing standout Ron Fellows. The car returned to the site of its debut when it raced at Sonoma in June. It qualified a respectable 11th and was en route to a top-10 finish before an accident with Jeff Burton in treacherous turn 11 dropped Stewart from ninth to 28th when the checkered flag waved. In preparation for the year’s second and final road-course race at Watkins Glen, Max Papis tested Chassis No. 14-731 July 30 at Road Atlanta. Now, as Stewart recuperates from a leg injury sustained in a Sprint Car crash Monday night, Papis is back behind the wheel of Chassis No. 14-731 for this weekend’s race at Watkins Glen.
