I sold my 2010 560-4 Spyder and just got this 2018 R8 V10 Spyder. This is my first outing into the mountains of Angeles Crest.
I don't know what the precise capacity of the gas tank on my new Spyder is but I filled up in Sunland before I got on Big Tujanga to go up to Angeles Crest and the smiles did not let up until I got this message "Would you like directions to the nearest gas station?" I thought to myself: HELL NO! I'm having way too much fun. Then I saw my range. 8 miles. It turns out I ran through almost an entire tank of gas. At an indicated 8 mpg and about a 20 gallon tank that should be 160 miles of mountain driving.
Here are the videos:
