Porsche track days prove refueling never looked so good. YouTube user AlwinSV has just uploaded an incredible video of a Porsche track day. Make sure you stick around until the end, as the GT3 RS 4.0 makes one mean sound when it is full of the black drink.Even the tailights on some of these racers are show-worthy.The Porsches seen in this video were filling up in between runs on the racetrack. We honestly can\'t think of a better way to spend an afternoon - even for the guy at the gas pumps.
