While browsing the orgy of videos over at YouTube this afternoon, I stumbled upon a rather impressive display of top speed tests involving a Mercedes SLR, Ferrari Enzo, Lamborghini Murcielago, Porsche Carrera GT and Aston Martin DB9.

Although I'm sure you can already guess which vehicle took top honors, the SLR performed admirably, sharing second place with the Porsche Carrera GT after achieving a top speed of 207.5 mph.  As for the Enzo, a top speed of 220.59 mph garnered it king of the supercars.
