After the Brazilian Grand Prix was in the books, Sebastian Vettel and Mark Webber headed to the garage for a ceremonial final engine start that not only signified the close of the 2013 campaign, but the end of F1's V8 era. And it was awesome.
The ensuing sensory carnival is spectacular, with red-hot glowing headers and apocalyptic screams from the RB9's V8 as it revs to 22,000 RPM. Turn it up and listen. Your co-workers may hate you afterward, but you'll feel too good to care.
