The newer mustang vehicles get their attitude from the oldschool passion of the early model mustangs. Really muscular body lines and great V8 engines , place the car into the category of muscle cars.  Mustangs have a lineage of street cars with steroids they are meant to be driven hard and have inherited in their DNA a street credibility. Other manufacturers are bringing alive old symbols of the muscle era, thus inviting a new generation to be part of that particular era in time.
