Last week, I went on a cross-country road trip from SC to CA in my 2014 A6 TDI.
It was a solo drive, but it was a similar trip length to the one Audi did with a bunch of bloggers/press people in a TDI fleet.
I averaged 37.64 mpg.
More importantly, I managed to travel 2,451.6 miles
. I took several breaks and made frequent stops for fuel and food. Starbucks was the biggest time waster of all.
I left SC at 11:30pm (EDT) Wednesday and arrived at my destination in CA at 8:09pm (PDT) Friday, making the entire trip in 47h:39m
- accounting for the time zone changes. I don't recall how much of that time was spent actually driving, but I will let you know that my average speed was somewhere in the 72mph range
. Keep in mind, I had 70, 75, and 80 mph speed limits to enjoy in most of Texas - and it still took an entire day to cross that state.
I wasn't hauling *** as much as I was using ACC and lane keeping assist most of the trip.
The major differences between my trip and the one Audi did, was that I didn't have my tires set to 51psi and I didn't have four adults in the car.
As far as fuel stops, I stopped at these mileage intervals (because of safe areas, decent fuel prices, and proximity to food and coffee) :
350.5 miles = 8.87 Gal (Tuscaloosa, AL)
307.3 miles = 8.21 Gal (West Monroe, LA)
511.9 miles = 14.05 Gal (Roscoe, TX)
394.5 miles = 10.75 Gal (El Paso, TX)
564.2 miles = 14.66 Gal (Tucson, AZ)
323.2 miles = 8.59 Gal (Los Angeles, CA)
I was also dollar cost averaging since I was going from one of the most inexpensive states to fuel-up to one of the most expense. To my surprise, when I got to my destination, I filled up the tank to get my final trip stats, and found that diesel is 2 cents more than 87 octane. It happens in Los Angeles once in a while, but I didn't expect diesel to be so much cheaper than 91 octane. Contrast that with the diesel fuel shortage on the East Coast, and the prices I paid to cross the country were within a decent range (until I got to CA).
