One of the enduring lessons of the car game is that good vehicles don’t always sell well. As a car writer who took on news analysis before ever getting manufacturer-sponsored time behind the wheel, this lesson can’t help but tinge my impressions of a road test. So when my first weeklong tester arrived in the form of a Q7 TDI, I felt no desire to justify Audi’s decision to bring the thing to market. After all, by any reasonable analysis, the brand built by Quattro wagons should have been the primary beneficiary of America’s SUV craze. Or, at least its worst enemy. Instead the Q7 showed up for the party fashionably dressed but fashionably late. And very few wanted to buy it. With the high price of luxo ute party fuel already killing the festive vibes, is switching to a new drink enough to make Audi’s SUV sales party like its 1999?
