What Is A S550 Mustang? - What Is A S550 Mustang?

The “S550” codename is the model of the 6th generation of the Mustang family and spans from 2015 to present. This is the first Mustang to be marketed and sold globally, and also the first time that they have been produced as right-hand drive as well as the traditional left hand that we are accustomed to. This is all part of Ford’s “One Ford” business plan which applies to other Ford vehicles. In the article we will go over every aspect of the S550 incredible design and how it has been improved from earlier versions.


BACKGROUND


This model was released on December 5, 2013 with same-day media events in cities all over the world. This 2015 Mustang marked the 50th anniversary of Mustang production that first began in March of 1964. Development for the S550 began in 2009 under chief engineer Dave Pericak and exterior design director Joel Piaskowski. In December of 2010 an exterior design theme was proposed by Kemal Curic from Ford’s Cologne, Germany design studios and was selected by Ford’s design management team. So, Ford relocated Curic to their design studio in Dearborn on January 2011. During the middle of development, the original design made by Curic was rejected by Ford’s executives, which resulted in rapid changes. 3 different exterior design proposals were made in September 2012 which resulted in the first proposal being approved by Ford management. The final design was locked in on December 2012 which was 20 months ahead of schedule. The interior design program had begun in Spring of 2010 under Doyle Letson and by late 2011 the final interior proposal was settled on and combined exterior theme proposals 1 and 2. As of June 2012, the final exterior was locked. So, the first test mules in 2010 model year bodies were spotted earlier in June 2012, and the first S550 prototypes were built five months later in May 2013.
