They said driving the 836 miles from Albuquerque to San Diego on one 13.2 gallon tank of diesel would be challenging. They weren't kidding.
Audi supplied me with a car—the fuel-sipping 2015 A3 TDi—topped off and sealed the tank, then paired me with a fellow journalist for the adventure. The obvious warnings, ominous statements, and downright threats emanating from Audi personnel made it seem like this excursion would be more Apollo mission than scenic road trip, and I had no idea whether or not I could, or would, succeed.
This is what that drive was like.
