In my case, one such recent experience involved being in a convoy of 2014 Audi R8 Coupes and Spyders on a nighttime run in the Tyrollean Alps. While it's true that I had achieved higher velocities on a racetrack earlier in the trip in a V10 Plus, it was the speedy ascents and descents on that stretch of pitch-dark alpine road that have stuck with me. The sounds of our groupe's V10s ricocheting off the rock walls and snowpack was, to appropriately employ a criminally overused word, epic.
I have since decided that I very much need the Audi V10 as an alarm clock sound on my phone. Crank the volume on the 550-horsepower video below and see if you don't agree.
