Awesome video comparison here of the Porsche 911 GT3 RS 4.0 and the Mercedes-Benz C63 AMG Black Series against the BMW M3 GTS. Have a look!
Chris Harris recently took it up on himself to line up a three very expensive, very powerful German track-bred machines for a little showdown. With names like the Porsche GT3 RS 4.0, BMW M3 GTS and the Mercedes-Benz C63 AMG Black Series, the half-hour clip all but guarantees some giggles. Since these are all coupes that are supposed to be able to pull double duty on the street and on track, Harris puts one and all through a two-day drive.
