Next Dodge Viper will shed some rough edges

During a conversation with Dodge boss Reid Bigland at the Los Angeles auto show, Bigland told me the redesigned Viper "will appeal to a broader segment of the market." The car is expected to debut in 2012 but is not likely to appear at the Detroit auto show, he says. Today's Viper is essentially a street-legal race car.
