This whole year has been amazing. What a great car. I've never had a car like this at Texas. We finally had one and put it in position."^[29] Johnson was happy with his second-place result, saying, "It was nice to get our car up front and get some clean air on it. We had to work really hard all day long to keep the car right. I'm very proud of the team."^[30] Third-place finisher Biffle was candid with his performance: "We worked our way all the way back to fourth, third – 15 more laps, would've passed [runner-up Jimmie Johnson] and then a little while longer we could've gotten [Gordon]. But, I just ran out of time, lost track position and weren't able to capitalize on it."^[31]

Earnhardt described his accident late in the race as him "Trying too hard and run well, and just got in to the wall down there in the middle of one and two. The car jumped sideways" and talked about his performance, "We were running pretty good all day. We were really fast."^[32] Edwards appeared to be certain that there would have been a different result had his slow pit stop late in the race not happened, saying, "I thought, 'If we can have just one more [good pit stop], we'll be all right. And then we went in leading and came out 11th, and that's what cost us the race."^[25] His teammate Kenseth commented on the lug nut fault that lost him positions and caused him to finish fifth, "You can't really do much about it. We just got to the back and it was extremely tough to pass, and we were just stuck back there racing with them guys."^[24] Stewart described his fourth-place as his team being "good today, we just weren't good enough", and said his team's vehicle was the quickest on the circuit at any time during the race after approximately 25 laps.^[23] Eighth-placed finisher Kurt Busch said his team believed that they could not challenge the major competitors, but admitted his strong result was "exactly what we needed. ... Our car was better on the long runs. We needed to be out there as long as we could and stretch it out."^[23]
