THE AUTO UNION LUCCA
REBORN
Before the modern hypercar, there was the “Rennlimousine”. Audi Tradition has painstakingly recreated the 1935 Auto Union Lucca—a 16-cylinder, 326 km/h testament to absolute engineering madness.
The Golden Age of Speed
In the 1930s, motorsport wasn’t just entertainment; it was a visceral, heavily funded proxy war between nations and engineering giants. Mercedes-Benz (the star) and Auto Union (the four rings) were locked in a brutal arms race, pushing physics and human bravery to their absolute limits. Out of this fiery crucible emerged the Auto Union Lucca, a vehicle so radical it was dubbed the “Rennlimousine” (racing sedan).
On February 15, 1935, driven by legendary hill-climb specialist Hans Stuck, this streamlined missile hit a measured top speed of 326.975 km/h on an Italian autostrada. Now, after three years of painstaking work by British restoration specialists Crosthwaite & Gardiner, Audi Tradition has brought this masterpiece back to life. And we at Nitro Cartel are here to dissect what makes it so special.

Design & Aerodynamics: Sculpted by the Wind
This is where the Auto Union Lucca diverges drastically from the open-wheel Grand Prix cars of its era. It represents one of the earliest applications of rigorous aerodynamic wind-tunnel testing in European racing. The original body was crafted entirely from light metal, featuring an enclosed cockpit (a rarity at the time), a tapered fin-like tail, and teardrop-shaped wheel arches covering the spoked wheels.
The recreated 2026 model is visually flawless, finished in a stunning “Cellulose silver.” During testing in Audi’s modern wind tunnel, the recreation registered a drag coefficient of 0.43. While that might sound high compared to a modern EV, for a 1935 vehicle generating massive cooling drag, it was revolutionary.
The Powertrain: 16 Cylinders of Fury
The original Lucca car ran a 5-liter, 343 PS engine. However, to ensure the 2026 recreation can survive modern demonstration runs without melting down, Audi Tradition made a brilliant swap. They installed the monstrous 6.0-liter, 16-cylinder supercharged engine from the 1936 Auto Union Type C.
Visually identical to the 5-liter unit, this mechanical leviathan produces a staggering 520 PS (382 kW) at just 4,500 rpm. Keep in mind, this engine is bolted into a chassis that weighs a mere 960 kg. It doesn’t run on standard pump gas, either. The fueling mix is a highly volatile cocktail: 50% methanol, 40% premium unleaded, and 10% toluene. The sound of this supercharged 16-cylinder firing up is less “car” and more “low-flying aircraft.”
Driving Experience: Raw, Unfiltered Terror (and Glory)
While modern hypercars rely on torque vectoring, traction control, and ABS to manage 500+ horsepower, the Lucca has none of that. You are sitting inches ahead of a screaming mid-mounted V16, gripping a massive steering wheel, wrestling with skinny tires that offer minimal grip.
It requires a level of mechanical sympathy and bravery that modern driving simply doesn’t demand. When Bernd Rosemeyer drove a similar “Rennlimousine” at the Avus race in May 1935, a tire burst at 290 km/h. This car demands absolute respect. Audi wisely integrated some cooling modifications from the later Avus races into this recreation to prevent the thermal nightmares that plagued the original drivers.
The 1930s Record Landscape
| Vehicle | Year | Engine / Power | Notable Top Speed |
|---|---|---|---|
| Auto Union Lucca (Original) | 1935 | 5.0L V16 (~343 PS) | 326.975 km/h |
| Mercedes-Benz W25 Rekordwagen | 1934 | Inline-8 | 316.592 km/h |
| Auto Union Type C Streamliner | 1937 | 6.0L V16 (520 PS) | Over 400 km/h |
| Mercedes-Benz W125 Rekordwagen | 1938 | 5.6L V12 (736 PS) | 432.7 km/h |
Pros & Cons of the Recreation
The Good
- A flawless, handcrafted visual recreation of a lost piece of motorsport history.
- Utilizes the legendary 6.0L V16 from the Type C, ensuring blistering performance and reliability.
- Incredible attention to aerodynamic detail, resulting in a verified 0.43 drag coefficient.
- Not just a static museum piece—it will be driven in anger at the Goodwood Festival of Speed.
The Challenges
- It is a one-off project; you cannot buy one.
- Requires a highly specific, toxic fuel mixture (methanol/toluene) to run properly.
- Safety standards remain firmly rooted in the 1930s—driving it is an exercise in extreme risk management.
Enthusiast’s Guide
Why You Should Care
Because modern supercars are often sanitized by electronics. The Auto Union Lucca reminds us of a time when speed required massive displacement, terrifying aerodynamics, and drivers with absolute nerves of steel. It’s the genesis of the modern hypercar.
Where to See It
While the original made its mark on the Italian autostrada, you can witness this V16 monster in motion at the Goodwood Festival of Speed (July 9-12, 2026). Seeing and hearing it run up the hill will be a religious experience for any gearhead.
Best For
Automotive historians, engineering nerds, and anyone who thinks modern Formula 1 cars are too quiet. This is raw, mechanical violence wrapped in a beautiful, silver, aerodynamic shell.

Nitro Cartel Final Verdict
You can’t buy it, and you probably wouldn’t have the courage to drive it at its limits anyway. But the recreated Auto Union Lucca is a 10/10 achievement by Audi Tradition and Crosthwaite & Gardiner. By fusing the stunning aerodynamic shape of the 1935 record breaker with the brutal 6.0L V16 from the Type C, they have created a rolling, fire-breathing monument to human ingenuity. It is a terrifyingly beautiful reminder of why we fell in love with motorsport in the first place.
HISTORIC MASTERPIECE
About the Evolution of Luxury & Speed
Before modern luxury car brands debated the merits of the audi electric car or an audi ev, the pursuit of performance looked very different. Today, whether you walk into an audi dealership near me to check the latest audi q3 price or configure an audi q8 etron, that legacy of engineering lives on. The DNA of 1930s record breakers can be traced directly to modern performance machines like the audi rs6, audi r8, and audi rs 5.
While the top most expensive car in the world today might be heavily computerized—often found among maybachs, maseratis, or a rolls royce phantom—true enthusiasts still revere the raw mechanical power of the past. From affordable luxury cars to navigating the world of used luxury cars, understanding the history of the four rings gives new context to every audi a4, audi q5, or audi sq8 on the road today.
