November 25, 2009 1:40 AM Chris Winkler certainly knew what the 2010 Viper SRT10 ACR was made of..he's an engineer on the program. But he really found out what the snake could do when he slipped behind the wheel, used the racing skills he's honed and took it through a lap at the famed Laguna Seca race circuit in record time. Winkler takes us through each and every turn of the punishing course and explains just how he tamed it.
