Porsche Brands 50-Year Journey: From Audacious Beginnings to Automotive Greatness
Passion for speed, engineering brilliance, and unrelenting innovation are the Porsche brand’s legendary motorsport legacy cornerstones. This year marks a special milestone in that story. Porsche is celebrating 50 years of racing heritage, driven by the spirit of bold engineering and the unforgettable debut of the street-legal 917, a car that redefined what was possible both on and off the track.
At Porsche of Colorado Springs in Colorado Springs, CO, we’re thrilled to reflect on this chapter of the Porsche brand’s history. It reminds us that every Porsche on our showroom floor carries the DNA of a brand unafraid to dream bigger and drive further.

The Road-Going 917: A Dare That Changed Everything
On April 28, 1975, a one-of-a-kind Porsche 917 left the Weissach development center. Unlike its predecessors, this 917 wasn’t headed to a racetrack. Instead, it pointed toward public roads, a concept almost unthinkable then. What began as a daring experiment ended in Paris, hundreds of miles away, after a spirited road trip that would become a legend.
This wasn’t just 917. Chassis 30 had seen track duty but was transformed into something never seen before: a street-legal endurance racer. This modification wasn’t for mass production or corporate publicity but for a private customer with a clear vision. Gregorio Rossi di Montelera, also known as Count Rossi, was no ordinary enthusiast. He was a powerboat racer, a bobsledder, and a Porsche devotee with an appetite for the extraordinary.

Martini Silver, Paris Bound
Count Rossi’s request led to what many consider one of the boldest engineering feats in the Porsche brand’s history. Finished in Martini Silver and outfitted with features required by road law, the car wore rudimentary mufflers, side mirrors, indicators, and even a horn. A spare tire was tucked beneath the rear clamshell, meeting another requirement.
Inside, the transformation was equally thoughtful. The 917 racing roots weren’t erased; they were paired with a touch of elegance. Both seats, originally mandated by endurance racing rules, were re-covered in tan leather supplied by Hermès. The suede-lined interior added refinement, while the wooden gear knob and lightweight drilled key preserved its motorsport soul.

This blend of racing performance and road-worthy modifications made the 917 street car truly unique. It didn’t just turn heads; it turned the idea of what a road car could be on its head. Count Rossi even registered it with Alabama plates, adding yet another layer of intrigue to the tale.

Living Legacy: A Machine Still on the Move
Today, the same 917 continues to stir the senses. Now, living in the south of France, it still takes to the roads. Registered in the U.K., lovingly restored, and driven with the same joy it inspired 50 years ago, it still takes to the roads. Despite some restoration work, its original paint and interior have been carefully preserved, allowing history to live and breathe through its bodywork and cabin.
This iconic Porsche reminds us of the brand’s enduring commitment to pushing boundaries. It wasn’t just about speed; it was about turning ideas into reality, no matter how audacious. That pioneering spirit lives on in today’s Porsche race cars and production models.
