1,682 miles in a 2014 Audi A8 L TDI - Part 2

Interruptions like the Canadian Grand Prix, Le Mans, Pikes Peak, that ridiculous Porsche 911 GT3 and the really good, really outrageous Jeep Cherokee, are among the distractions that delayed the conclusion of this tale. If you'll remember, in Part 1 we started off in a parking lot in Sebring with an Audi A8, headed anywhere that would empty our tank, and after five days in Miami and Ft. Lauderdale and Pompano Beach we bolted in the middle of the night for a breakfast date at an IHOP a couple hundred miles away.
We last left proceedings at a Chevron pump beside the West Florida Turnpike, somewhere around midnight in the humid wilds, having done 660 miles and spent $89.40 to put 20.992 gallons in the great white whale. We had done average speed of 31 miles per hour at an average rate of 27.5 miles per gallon. Those kinds of numbers, as we demonstrated, are good enough to put you in the fuel economy orbit of the Toyota Corolla - to be precise, it only cost $6.40 more to cover that 660 miles in the A8 TDI than it would in the Japanese compact. That led us to conclude that there were just a couple of Starbucks Venti lattes between the A8 and the Corolla, assuming we conveniently ignore the two cars' purchase prices. Turns out we were wrong: it didn't take long for a commenter named "mike" to set us straight when he wrote, "It's clear you weren't lying about not frequenting Starbucks...no way could you get two venti lattes for $6.40." Mike, we salute you - our ignorance of terrible coffee has served the higher purpose of emphasizing the strong case made by the diesel Audi.
But that A8... well, the wheels were still on the damn thing and we had to drive them off. That meant five more days of pilot duty to get us from wherever the hell we were to Wildwood and Daytona Beach, FL, then Brunswick, Macon and Atlanta, GA, then Birmingham, AL, and back to Atlanta.

2013 Audi S8

Italy To Monaco In Ingolstadt's Crushing Performance Saloon
I had an engagement a while back with the Audi RS5 Cabriolet in Monaco, and getting me from my lair in northern Italy by plane connection is an utter waste of time since the first flight is always to either Paris, Zurich, or Rome, three cities not at all on the way to Monaco. So I phoned Audi Italia about a quick loan of a car for the three-hour-ish drive to this event, and they were simpatici enough to propose that I keep whatever they gave me for two weeks. And what they gave me was a loaded Audi S8 with properly chosen 20-inch Dunlop SP Winter Sport treads attached.
This was about to be a much cooler two weeks than I had planned.

2015 Audi A3 TDI Challenge

I officially gave up after 758 miles. The 15 or so miles leading up to this decision were spent in the right lane of Southern California's I-8 freeway, hazard lights blinking, climbing uphill at just over 40 miles per hour. After two days of sweating to the oldies (okay, a mix of SiriusXM Classic Rewind and First Wave), I had covered those 758 miles in a 2015 Audi A3 TDI on one tank of diesel fuel. And when I say sweating, I mean it quite literally. In order to maximize fuel efficiency, my co-driver and I kept the air conditioning off, even when the direct sunlight in the California desert had outside temperatures hovering around 90 degrees. I had been doing this hypermiling exercise for two days, the car was getting stinky, and I was ready to hear the sweet "thhhhhhhwack" of satisfaction that would finally come from peeling my sweat-soaked self off the A3's leather seat. Sexy, I know.
Audi had challenged me to drive 834 miles from Albuquerque, NM to San Diego, CA, on just one 13.2-gallon tank of diesel fuel. If you believe the EPA's highway fuel economy rating of 43 miles per gallon, this means I should have sputtered to a stop after 568 miles. But I went a grand total of 758 - that's 59.4 mpg - and I could have kept going. In fact, two teams made it the full 834 miles on their one allotted tank of fuel. That's over 63 mpg. That's twenty miles per gallon better than EPA estimates.
The TDI Challenge took me through three states over the course of two days, and the 834-mile journey wasn't just a simple highway cruise. I negotiated uphill climbs, long series of involving switchbacks through the mountains and elevations that ranged from 220 feet below sea level to nearly 8,000 feet above. I learned that super-crazy-efficient driving like this an incredibly challenging game that takes serious skill. But I also learned that if you're going to attempt to stomp all over the EPA's numbers, the Audi A3 TDI is one heck of a car for the journey.
