The all-aluminum unibody structure is 39 percent lighter than the steel body in the outgoing model. This enables a total vehicle weight savings of up to 926lbs, depending on market and specifications. The US specification vehicle with the naturally-aspirated 5-liter V8 will be approximately 700lbs lighter than the outgoing equivalent. This new aluminum platform delivers significant enhancements in performance and agility, along with an improvement in fuel economy and reduction in CO2 emissions.
