Built to showcase Porsche's stature as a world leader in automotive technology, the Porsche 959 utilized every ounce of brilliance within Porsche R&D when it appeared as the "Gruppe B" at the 1983 Frankfurt Auto Show. It left behind the traditional engineering of the Porsche 911 (which still showed evidence of the Volkswagen Beetle) and embraced the future: a turbocharged, liquid-cooled flat-6, six-speed transmission, all-wheel drive, double-wishbone suspension and even run-flat tires.
