Also, neither Penn, Schoen and Berland nor the NACS indicated how their questions were phrased. As we pointed out in our report on the Audi study, the wording of questions can easily predispose respondents to a particular set of answers.
On the other hand, the NACS doesn't have much to gain from this study -- in fact, the results seem to paint a moderately bleak picture for the convenience-story industry. Audi, however, has a lot of money and product at stake in selling diesels, which makes its commissioned study seem suspect, at the very least.
For now, we'll simply take this survey as more evidence that the diesel vs. electric battle is not as clear-cut as pundits would have us believe. Hopefully, someone will publish a more thorough study of consumer habits down the line.
