The Commission

Bespoke Style, Iconic Finish

The Helderburg 110 “Acrux” stands as an extraordinary blend of classic design, modern luxury, and custom engineering. This Beluga Black D110, highlighted in the latest Helderburg test drive video, sets itself apart not only through its striking appearance but also as a rare Helderburg build with an automatic transmission—a true accomplishment for Defender enthusiasts seeking ease without sacrificing authenticity or performance.

Finished in Beluga Black with a subtle Chorus Gray Metallic roof, Acrux emanates a bespoke, understated luxury. This dual-tone combination creates a visual statement—refined yet adventurous. The interior is equally impressive, featuring 100% saddle-colored cowhide that delivers luxury and durability far beyond the original Defender’s utilitarian roots. The Italian Alcantara suede headliner in Austin Black and billet aluminum details further elevate the tactile experience, while stainless steel accents and premium materials run throughout the cabin.

The Automatic Transmission Advantage

Land Rover never offered an automatic transmission in the “rest of world” (RoW) Defender 110 models, making Acrux a truly unique offering. Unlike North American versions that used old petrol GM engines and automatics, this Defender boasts a modern, custom-fabricated automatic paired to the legendary 300TDI turbo diesel engine. The result is convenience and reliability—a Defender that anyone can drive, whether navigating city traffic or seeking a daily driver for stop-and-go commutes. The transmission upgrade makes Acrux perfect for those who do not wish to drive a manual, ensuring driving ease in any situation.

Comprehensive Restoration and Engineering

Acrux is more than a cosmetic restoration; it’s a frame-off, nut-and-bolt rebuild. Every major component is brand new, including the engine, transmission, transfer case, differentials, prop shafts, doors, fenders, hood, glass, and seals. The new doors use Helderburg’s advanced weather-sealing system for improved comfort and longevity. Inside, noise-dampening insulation ensures a quiet, refined ride—unusual for vintage Defenders and essential for modern driving expectations.

Suspension, Brakes, and Performance

This D110 features a Bilstein suspension system with polyurethane bushings and progressive coil springs, providing remarkable comfort and responsive handling. The Helderburg performance brake package includes large cross-drilled rotors, six-piston “big red” calipers on the front, and four-piston rear calipers, ensuring top-tier stopping power. Kahn wheels fitted with Cooper STT all-terrain tires combine classic Defender looks with all-around street and trail capability. Performance enhancements such as the VNT turbo, performance exhaust, and upgraded cylinder head ensure robust, reliable power and fuel efficiency—up to 28-32 mpg—a remarkable figure for such a capable vehicle.

Seating, Practicality, and Adventure-Ready

Acrux accommodates up to eight passengers with stadium second-row seats for improved visibility, a central cubby, and classic rear benches. This makes it perfect for family adventures, camping in remote Maine forests, or road-tripping up to Nova Scotia. The thoughtful interior layout and robust mechanicals mean Acrux is ready for daily driving, long-distance travel, or rural escapes.

The Helderburg Legacy

With only a handful of these automatic transmission builds ever produced by Helderburg, Acrux is a rare opportunity for collectors or enthusiasts seeking the ultimate Defender experience. Every detail is addressed for comfort, performance, and style, making it as at home on the boulevard as it is off the beaten path. Its combination of modern convenience, classic Land Rover style, and bespoke craftsmanship ensures Acrux will be cherished for decades, continuing the Defender legacy in a distinctly modern way.

Four Styles, One Custom Process

A Helderburg is not one look. It is your own.

Acrux is one direction. Every Helderburg is custom, designed around the owner rather than chosen from a catalogue, and most commissions draw from one or two of these four. The expedition build is the one most people picture first. It is only the beginning of what a custom Defender by Helderburg can be.

Why a Helderburg Drives Differently

The difference is not cosmetic alone.

The architecture itself has been re-engineered. If you want the full picture of what is under a Helderburg before you speak to Paul, two doorways.

The Twelve Systems

Acrux carries twelve proprietary Helderburg systems, found in no other restored, custom or restomod Defender. The drivetrain on the original block. A suspension with the body roll engineered out, widened at the chassis, not with spacers. A cabin built for the eighth hour, not the first.

Three Approaches. Only one is a Helderburg.

A classic Defender can be restored, restomodded, or re-engineered. A restomod replaces the body and drops in a GM V8 crate motor, no longer numbers matching. Respectfully, a kit car. A Helderburg keeps the original chassis and block, and re-engineers everything else.
