The Art of Rethinking the Automobile

With passion, a keen sense of style, and technical sophistication, Jochen Arden has been creating automobiles for over 50 years that continue to captivate Jaguar enthusiasts and collectors to this day.

What began as Jochen Arden’s fascination with Jaguar led to a unique success story—defined by a pursuit of technical perfection and timeless elegance.

From the original AJ 1 to today’s AJ 50 V12, these vehicles have combined design, performance, and craftsmanship. The brakes, suspension, and aerodynamics have been continuously refined, while the interiors have been custom-crafted from premium materials. The AJ 50 V12 carries on this tradition—as a modern interpretation of the legendary Jaguar E-Type, whose form continues to fascinate to this day. Synonymous with exclusive design, technical precision, and masterful craftsmanship, Arden embodies the rare balance between heritage and modernity—a true hidden gem in the world of luxury automotive manufacturers.

A restomod for
drivers and collectors

With 50 years of experience in Jaguar customization, the Arden AJ 50 V12 is an E-Type designed for the autobahn, Goodwood, and Highway 1. This V12 restomod goes far beyond classic Jaguar E-Type tuning: it combines Arden Jaguar tuning, craftsmanship in Krefeld, and a revolutionary 12-cylinder engine into a vehicle for drivers and collectors alike.

AJ 50 V12

State-of-the-art technology, custom design, and a newly developed 6.3-litres V12 engine—perfectly balanced for performance and character.

Fully digitized

The Arden AJ 50 V12 was fully digitized to reinforce the chassis and structure with precision and to develop bespoke components such as the Arden hardtop.

Precision in
every line

The Arden AJ 50 V12 takes its final shape in the wind tunnel. Here, airflow, balance, and stability are optimized down to the last detail until every element combines form and function. This project draws on decades of engineering experience in the customization of road and race cars.

Tradition meets
innovation

Every detail of the bodywork is a testament to precision craftsmanship—especially the custom-made aluminum hood, crafted with the same dedication that defines every Arden model. The entire body has been reinforced and tested according to the strictest standards of the German TÜV. As a result, the AJ 50 V12 not only meets the highest standards of design and build quality, but also of structural integrity and safety.

The complete digitization of the AJ 50 enables precise development, customization, and production of the vehicle. Using CAD scans, Arden creates complex designs such as the elegantly shaped Arden hardtop. The custom-made aluminum hood combines traditional craftsmanship with state-of-the-art technology.

Reworked with the highest level of precision and enlarged to 6.3 litres, the V12 combines the fascination of classic mechanical engineering with the efficiency of modern technology. Whether in carburettor or fuel-injection specification, each engine is individually calibrated and paired with a 6-speed gearbox specifically designed for the twelve-cylinder engine, bringing performance, consumption and torque into a well-balanced relationship.

The engine operates noticeably more efficiently and economically while meeting the requirements of a contemporary, sustainably conceived powertrain.

For track day events and motorsport use, the engine is also available on request in Group C specification with more than 700 hp – a version that has already proven its performance in racing.

What makes the AJ 50 V12 so unique? Its presence. Every line, every detail, and every proportion embody 50 years of Arden engineering—all brought together in a vehicle that proudly carries on its heritage. One glance is enough to see: The AJ 50 V12 is more than just a car. It is Arden—in its purest form.
