A ghost from Zwickau: rebuilding the soul of a Pre-War roadster

The elegance of 1930s German roadsters is hard to resist. Think of icons like the legendary Autobahn Kurier or, like today, this impressive Horch Spezial Roadster. It stands before us as if it could take off at any moment—radiating speed and power, even at a complete standstill. Its flowing lines invite you to trace them with your fingers, much like a child discovering a pedal car for the first time.

 

We're in an unassuming neighborhood of a European capital. After passing through three gates and a heavily secured entrance, we arrive at a stunning garage. And there it is: a car that recently hit the market and instantly captured our attention. In person, it’s even more striking than in the photos. A graceful presence—regal, yet sporty. A sculpted tiger stands guard over the vehicle, as its visibly proud owner begins to tell its story.

 

A rebirth with soul

What we’re looking at is a unique machine: a fully rebuilt Horch 853 Spezial Roadster, featuring a body designed by the famed coachbuilder Erdmann & Rossi. The original factory in Zwickau began operations as early as 1898 and would later produce exclusive bodies for the wealthiest clients. Only five to seven of these Spezial Roadsters were ever commissioned by Horch itself.

Sadly, much of the original documentation was lost—Horch’s factories and archives were completely destroyed during World War II. What is known is that this car was converted into a utility vehicle during the war and eventually ended up on a farm in Ukraine. That’s where Horch Classic found it. In partnership with the modern-day Erdmann & Rossi, a new body was crafted in 2014, built on the original chassis and following historical specifications to the letter. The project took over seven years and more than 5,000 hours to complete.

 

Engineering and performance

Beneath the long hood lies an impressive powerplant: an inline-eight engine with a displacement of 4,911 cc, delivering 100 horsepower. Featuring an overhead camshaft and ten main bearings, it was a technical marvel for its time. Everything about this car breathes quality. Even opening the hood requires real strength; the heavy sheet metal speaks of durability—though we do wonder if that might compromise performance somewhat.

The 853 was a forward-thinking vehicle in its day, equipped with independent rear suspension and a De Dion axle.
For comfort, a modern ZF five-speed gearbox has been installed—similar to those used in postwar Horch models—but the original transmission is still present. The engine and chassis are still a matching-numbers combination, which is highly sought after today, though we personally find that detail less important for a car of this stature.

The current owner acquired the car four years ago through a trade involving a Jaguar and two Bentleys. Since then, he has meticulously maintained it, even commissioning a custom-made travel bag to match the interior. And yet, he drives it far too little, and is now considering parting with his jewel.

A unique detail: this Horch is the only Erdmann & Rossi vehicle officially certified by the coachbuilder and restored under Audi’s supervision.

 

Unmistakable class

When we ask the owner to start the engine, he briefly disappears to fetch the key. “It hasn’t run in a few weeks,” he warns. But as soon as he presses the starter button, the engine comes to life effortlessly. A deep growl fills the space. “What a machine,” he says, smiling broadly.

 

We estimate the value of this car between €1.3 and €1.6 million. For context: a comparable Spezial Roadster by Gläser was sold last year for $3.3 million at the Junkyard Collection Sale. Considering the quality and provenance of this particular example, that valuation seems realistic—the restoration alone cost more than twice that amount.

Thanks for your remarks and let me try to answer your questions:

As far as the historical documents from Horch and Erdmann & Rossi confirm, about 7 Spezial Roadsters were manufactured. Only the very last one being a 855, all the others being 853’s. The first Spezial Roadsters were built in 1936/1937, the 855 did not exist. Only years later it made its introduction.

From #853177, this specific car, little is known about its early history yet. Since the specs (notably the wheelbase!) matched the Spezial Roadster configuration, Horch Classic decided to recreate this version with use of as many of original parts as possible. The ‘no expense spared’ project was sanctioned by Audi Tradition and executed with the research and support from Erdmann & Rossi. It is the only Horch 853 Spezial Roadster in the world certified by Erdmann & Rossi.

Thank you for the explanation - very much appreciated. Indeed, a slightly shorter 853A wheelbase was also used for the later 855 "Spezialroadster" according to the literature (Kirchberg/Pönisch, Horch - Typen, Technik, Modelle). However, roadster versions were manufactured also on the basis of the earlier 853A, not just by Erdmann&Rossi, but also by Voll& Ruhrbeck, for example. These looked different and not quite as appealing as the one used as a model for the reconstruction of the "Spezialroadster". According to the older literature (Peter Kirchberg, Bildatlas Auto Union), the "Spezialroadster" body was also offered on the standard wheel basis of the 853A. Hence, the combination of a shorter wheel base Horch 853A and a reconstructed "Spezialroadster" might not be the only possible solution, but a solution well consistent with historical evidence.

You’re very welcome and your input is spot on.

The ‘A’ in 853A stands for ‘Autobahn’. It indicates only that the car was equipped with the optional 5-speed transmission.

Where Mercedes-Benz went for the Kompressor solution (resulting in a lot of reliability issues), Horch went for straightforward torque and an overdrive to reach high speed cruising. The original 4-speed ZF Aphon however, was the most silent gearbox of its era, hence the ‘noiseless’ name.

Is that car really a Horch 853? I thought this particular "Spezialroadster" by Erdmann & Rossi was sold as a Horch 855. Or are we dealing with an ordinary 853 originally that was just rebodied as a 855?
