The Shelby GT500 has always been fast, but it's never been this fast around a track. And that's all thanks to the major and minor improvements the SVT team made for the 2011 model. It's lighter, more fuel-efficient, and can actually hit a turn without making you soil yourself. Granted, you will need the SVT Performance to get the most out of this car, but with it, it's one the most enjoyable drives on the road today.
