Unveiling the Trailblazer: The Untold Story of the Original 1973 Porsche 911 Turbo Concept

When the curtains rolled back at the 1973 Frankfurt auto show, Porsche set the automotive world ablaze, hinting at the future of high-octane exhilaration with the unveiling of a concept that prefigured the iconic 930-generation 911 Turbo. This wasn't just any concept; it was a herald of revolution, turbocharging not only its engine but the dreams of speed enthusiasts worldwide.

Fast forward several decades, and this prototype has emerged once again, gloriously restored to its inaugural luster by its current steward. The rebirth isn't just a testament to the car's enduring allure but also a fascinating journey back to its Frankfurt inception.

The twist in this tale? The concept displayed in 1973 didn't house a turbocharged engine. Developmental hiccups led Porsche to employ a stand-in: a naturally aspirated engine accompanied by a faux turbo setup ingeniously crafted from wood and painted to mimic metal. Despite this, the prototype carved a niche as the first 911 emblazoned with 'Turbo'—a tag that heralded its future prowess, albeit then represented by a hand-painted graphic adorning its sides.

Rooted in a 1973 911 S chassis (chassis number 9113300157), the concept was a glimpse into the future 911 Turbo's broader physique, featuring an ostentatious rear wing and larger Fuchs-style wheels that would become synonymous with the model's pugnacious aesthetic.

After its reveal, the concept graced additional exhibitions, later serving as a crucible for developing racing components once the 911 Turbo entered production in 1974. Its journey took a pivotal turn in 1975, catching the eye of Alan Hamilton—racing driver and Porsche's Australian importer—during a factory visit, leading to its acquisition.

This storied prototype has since passed through an array of custodians, now residing within Europe's borders, poised for a public showcase at an event slated for Hampton Court Palace in the U.K. on August 30.

While not officially the first 911 Turbo—praise reserved for a distinct, narrow-bodied variant adorned with a 2.7-liter turbocharged flat-6 and delivered to Louise Piëch, Porsche's matriarch, before the Frankfurt exhibition—this prototype's tale is steeped in the lore of Porsche's turbocharged odyssey, enshrined within the hallowed halls of the Porsche Museum in Stuttgart.
