#14-Tony Stewart - Chassis No. 14-731: This car debuted in impressive fashion last June at Sonoma as 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 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 returns to site of its debut race when it competes in this weekend’s Toyota SaveMart 350k.
