In an era when speed records were chased with near-obsessive intensity, few machines captured the imagination quite like the Auto Union Lucca. Now, more than 90 years later, Audi has brought that legend back to life. Recreated by Audi Tradition and unveiled in the Italian city where it made history, the Auto Union Lucca stands as both a tribute to engineering brilliance and a reminder of one of motorsport’s most daring eras.

The original car earned its place in history on February 15, 1935, when it blasted down a stretch of autostrada near Lucca at an average speed of 320.267 km/h, with a recorded top speed of 326.975 km/h (about 203 mph). At a time when the world was captivated by speed, this achievement made headlines across Europe. It wasn’t just about numbers, it was about prestige, national pride, and technological supremacy. Auto Union, the precursor to modern Audi, was locked in fierce competition with Mercedes-Benz, pushing innovation to its limits in pursuit of dominance.

Motorsport Experimentation

The 1930s marked a golden age of motorsport experimentation. With the introduction of the 750-kilogram Grand Prix formula, manufacturers were forced to rethink design, leading to radical engineering solutions. Auto Union responded with mid-engine layouts, advanced aerodynamics, and powerful engines that challenged conventional thinking. The Lucca car, known at the time as a “Rennlimousine,” or racing sedan, was a direct product of this environment. It wasn’t just a race car; it was a purpose-built machine designed to slice through the air at unprecedented speeds.

To achieve its record-breaking performance, Auto Union engineers turned to wind tunnel testing, a relatively new approach in automotive design at the time. Working with the Berlin-Adlershof Aeronautical Research Institute, they developed a streamlined body that prioritized aerodynamic efficiency. The result was a striking silhouette defined by a long, tapered tail, enclosed cockpit, and smooth, uninterrupted surfaces. Every detail served a purpose, from the covered wheels to the carefully shaped air intakes that fed the engine.

16-Cylinder Power

Under the skin, the Lucca featured a 16-cylinder engine derived from Auto Union’s Grand Prix cars. While early versions produced around 343 horsepower, later developments would push output even higher. Combined with its lightweight construction and aerodynamic body, the car was capable of speeds that seemed almost unimaginable for the time. It wasn’t just fast, it looked fast, embodying what many would describe as the pure “aesthetic of speed.”

The road to its record wasn’t straightforward. Initially, Auto Union planned to challenge Mercedes-Benz’s benchmark on a stretch of road in Hungary, where rival driver Rudolf Caracciola had set impressive records the previous year. But poor weather conditions forced the team to relocate multiple times, eventually settling on a section of highway near Lucca. This adaptability proved crucial. In an era without modern logistics or forecasting, success often depended as much on quick decision-making as it did on engineering.

Record Attempt

When the record attempt finally took place, it drew significant attention. Thousands of spectators gathered, and official timekeepers used advanced chronometric equipment to verify the results. With driver Hans Stuck behind the wheel, the Lucca delivered on its promise, securing its place as one of the fastest road-going racing machines of its time. The achievement was immediately leveraged as a marketing victory, reinforcing Auto Union’s reputation as a technological leader.

Yet, as was often the case in motorsport, success was fleeting. Just a few months later, the Lucca and its sister car appeared at the Berlin Avus race, where they faced intense competition from Mercedes-Benz. Despite their speed, reliability issues prevented them from finishing, highlighting the relentless challenges of racing at the cutting edge. Still, the lessons learned from these machines would go on to influence future designs and solidify Auto Union’s legacy.

The Recreation

Fast forward to today, and the Auto Union Lucca has been painstakingly recreated by British specialists Crosthwaite & Gardiner. Using historical photographs, archival documents, and engineering expertise, the team spent more than three years bringing the car back to life. Every component was handcrafted, from the intricate bodywork to the complex mechanical systems. The result is a near-perfect recreation that captures both the look and spirit of the original.

Interestingly, the modern version incorporates subtle updates to ensure durability and functionality during demonstration runs. For example, it uses a later 6-liter V16 engine from the Auto Union Type C, which closely resembles the original unit but offers improved reliability. Minor adjustments to cooling and ventilation systems were also made, ensuring the car can perform safely in modern conditions without compromising its historical authenticity.

Advanced Design

The recreated Lucca also demonstrates just how advanced its original design was. Wind tunnel testing conducted during the restoration process revealed a drag coefficient of 0.43, an impressive figure even by modern standards. This underscores the ingenuity of the engineers who, nearly a century ago, were already exploring principles that continue to shape automotive design today.

Beyond its technical achievements, the Auto Union Lucca represents something deeper, the relentless human pursuit of progress. It embodies a time when engineers and drivers pushed boundaries with little regard for comfort or safety, driven by a desire to go faster than ever before. That spirit is captured in every curve and contour of the car, making it more than just a historical artifact, it’s a symbol of ambition and innovation.

Auto Union Lucca Future

Today, the Lucca takes its place among the legendary Silver Arrows in Audi’s historic collection, filling a gap that had long existed in the brand’s preservation of its racing heritage. Its debut in Italy, followed by appearances at events like the Goodwood Festival of Speed, ensures that a new generation of enthusiasts can experience the beauty and drama of this remarkable machine.

In many ways, the Auto Union Lucca is a bridge between past and present. It connects the daring experiments of the 1930s with the technological advancements of today, reminding us that innovation is a continuous journey. For Audi, it’s a chance to celebrate its roots while showcasing the enduring relevance of its engineering philosophy.

Ultimately, the Lucca is more than a record-breaking car, it’s a masterpiece. It combines breathtaking performance with elegant design in a way that feels timeless. And as it returns to the spotlight nearly a century after its original triumph, it serves as a powerful reminder that the pursuit of speed, beauty, and innovation is as compelling today as it was in 1935.
