Would a factory 2014 Mustang GT beat or lose to most Mercedes AMG's? I know most Mercedes AMG's have a bit more horsepower, but given the power to weight ratio of the Mustang GT with 420 BHP it is also generally about 800 to 1000 pounds lighter than the Mercedes. I ask because where I live I get a lot of AMG's picking races with me on the highway. I want to feel confident if I choose to engage. Thanks for any input in advance.
