When the conversation turns to limited-run performance convertibles, Renault is rarely the first name on anyone's lips. Yet, isn't it the quiet ones, the outliers, that often hold the most captivating stories? Every so often, a machine emerges that shatters preconceptions entirely. I stand before one such legend: the one-off Alpine GTA Turbo Cabriolet. It is a symphony of contradictions—quintessentially French in its soul, yet fearlessly reimagined by German engineering audacity. This is a car Renault itself never dared to build, a dream made tangible by those who believed the original GTA coupe was just the beginning.

My journey with this car begins with its ancestor, the original GTA coupe. Produced from 1986 to 1991, it was a lightweight, turbocharged grand tourer, an aerodynamic marvel that was an outlier in its own time. Sleek, purposeful, and razor-sharp. But what if it could breathe the open air? Alpine never intended for the GTA to go topless. Yet, a little-known German tuning house, Autohaus Pahnhenrich, gazed upon the French sports car and asked a different question: Why not? Their vision was one of more flair, more power, and far fewer roof panels.

Blessed with a steel backbone chassis and a glass-fiber body, the GTA’s structure was a canvas waiting for transformation. Removing the roof wasn't an act of vandalism, but of surgical precision. Pahnhenrich’s engineers reinforced the bulkhead, integrated a discreet rollover bar, and crafted a masterpiece that retained its roadworthiness. The result? A fully street-legal Renault GTA Turbo convertible, certified by Germany’s notoriously strict TÜV—a badge of honor proving this was no backyard hack job, but a legitimate work of automotive art.

But they didn't stop at simply removing the top. Oh no, this was an extreme reimagining. Their vision demanded more:

• A Dramatic Wide-Body Kit: Flared arches that hug the asphalt, giving the car a planted, predatory stance.

• Bespoke Engine Cover: Sculpted to perfection, hinting at the enhanced power within.

• Monstrous BBS Wheels: 15-inch three-piece alloys, with the rears stretching a massive 11 inches wide.

• Heart Transplant: The 2.5-liter turbocharged V6 was coaxed to produce an extra 20 horsepower, bringing the total to a potent 220 hp.

This power bump transformed an already quick coupe into a convertible rocket. The sensation of 0-60 mph in under six seconds, with the wind in your hair and the turbo’s whistle in your ears, is nothing short of transcendent. It matched the pace of Ferraris from its era, a French-German underdog whispering threats to Italian aristocrats. Can you feel the rebellion in that?

What makes this specific car utterly mesmerizing, however, is its state of preservation. With only 17,121 miles on its odometer, it is likely one of the lowest-mileage Alpine GTAs in existence, let alone a hand-built unicorn like this. Its allure is visual as much as it is mechanical:

I trace the lines of its bodywork, each curve a testament to its careful guardians. Its most recent custodian, acquiring it in 2023, treated it not as a static museum piece, but as a living legend. A new soft top was commissioned, a comprehensive mechanical refresh undertaken—no expense spared to keep this dream alive and eager for the next winding road. Every step of its life is captured in a dossier of devotion: the all-important TÜV paperwork, the V5 registration, and detailed service invoices. This isn't just a car; it's a documented biography of passion.

As I sit inside, the scent of aged leather wraps around me. The steering wheel feels alive in my hands. This machine is a question answered—a “what if” made real. It represents a moment when convention was ignored and passion was allowed to engineer its own reality. In 2025, as the automotive world charges headlong into an electric, homogenized future, this Renault Alpine GTA Turbo Cabriolet stands as a glorious relic of a more audacious, individualistic age. It is a poem written in steel, fiberglass, and horsepower, waiting for the next verse to be driven into existence. Who will be its next author?
