For serious 4×4 fans and Isuzu enthusiasts, a rare opportunity has just appeared: The 2017 Isuzu D-MAX LS-Terrain “Concept X” show car is officially up for sale. 

Far from a run-of-the-mill dual-cab ute, this one-off build was conceived as a factory-backed exploration of what the D-MAX platform could achieve when pushed to the extreme. Developed in Australia by Team Isuzu as part of their precision driving and engineering program, the Concept X was never intended for private ownership. 

Vehicles like this were primarily built for displays, promotional events and public appearances, making it an exceptionally rare chance to acquire a genuine manufacturer-backed concept. It’s important to note that this vehicle is sold unregistered and is not able to pass roadworthy in its current form. Any prospective buyer would need to undertake modifications or rectifications to meet state road legislation.

Built from the ground up

It’s based on the flagship D-MAX LS-T, but almost every visible and mechanical component of the Concept X has been custom engineered. Guards, bonnet, bullbar, suspension, and even structural elements were hand-fabricated. 

Sitting proudly on massive 38-inch Toyo Open Country M/T tyres – said to be the largest ever fitted to an Isuzu passenger vehicle – the Concept X features a seven-inch lift and a fully redesigned suspension with remote-reservoir shocks. Its extreme approach and departure angles (around 50° and 38°) place it firmly in the territory of purpose-built off-road machines.

Underneath, the rear leaf springs have been swapped for a custom MU-X-style five-link coil-spring setup, dramatically improving articulation for technical terrain. It also features a motorsport-grade braking system with oversized floating discs and multi-piston calipers. Plus, it’s loaded with functional off-road features including integrated front and rear winches, a fully custom alloy tray, and dedicated storage for spare wheels and fuel containers.

At its heart, the Concept X retains the proven 3.0-litre turbo-diesel engine paired with a six-speed automatic transmission. Aside from minor tuning, the drivetrain is untouched. Inside, the LS-T interior offers comfort and convenience, contrasting sharply with the radical exterior.
