Ineos Grenadier Portal Axle Edition Hits Production

The rugged Ineos Grenadier, already renowned for its off-road prowess, takes a monumental leap forward with the introduction of its production portal axle variant. Developed in partnership with German specialist LeTech, this enhanced Trialmaster edition delivers unprecedented ground clearance of 17.7 inches, transforming it into a beast capable of tackling the most demanding environments.

Engineering Marvel: How Portal Axles Revolutionize Off-Roading

Portal axles represent a pinnacle of off-road engineering, featuring gearboxes mounted at the wheel hubs that elevate the vehicle’s body above the axle centerline. This design effectively raises ride height without compromising suspension travel or drivetrain geometry. For the Grenadier, LeTech’s implementation adds approximately 7.3 inches (186mm) to the standard 10.4-inch clearance, resulting in a total of 17.7 inches (450mm).

Beyond height, portal axles improve approach, breakover, and departure angles, crucial for navigating steep inclines, deep ruts, and rocky outcrops. They also enhance wheel articulation, allowing tires to maintain contact with uneven surfaces. Wading depth surges from 31.5 inches (800mm) to 41.3 inches (1050mm), enabling crossings of substantial water obstacles without risk to the undercarriage.

Core Upgrades in the LeTech Conversion Package

Starting from the factory Trialmaster models built in Hambach, France, vehicles are shipped to LeTech’s Stuttgart facility for transformation. Key enhancements include:

• Heavy-duty five-link suspension: Front and rear setups optimized for extreme loads and articulation.
• 37-inch BFGoodrich Mud-Terrain tires: Mounted on 18-inch forged beadlock wheels from Hutchinson Industries for superior grip in mud, sand, and rocks.
• Integrated tire pressure control system: Allows real-time adjustments for varying terrains, from high-pressure highway runs to low-pressure off-road traction.
• High-performance braking: Upgraded components to handle the added mass and speeds.
• Front winch system: Robust recovery tool for self-extraction in sticky situations.

Additional practical additions like extended fenders, off-road running boards, a multi-function rear ladder with jerry can mount, spare tire carrier, LED rear working lamps, MAXTRAX sand ladders, and a loadspace drawer box with lockable storage elevate usability.

Preserved Powertrain and Performance Specs

The Grenadier retains its potent BMW-sourced engines: a 3.0-liter turbocharged inline-six diesel (B57) or petrol (B58), both paired with an eight-speed ZF automatic transmission and full-time four-wheel drive. Towing capacity holds at 3,500kg (7,716 lbs) braked, while payload reaches up to 540kg for the Station Wagon and 642kg for the Quartermaster, supported by an uprated Gross Vehicle Mass (GVM) of 4.2 tonnes.

Despite the modifications, the wider track and optimized weight distribution improve stability without sacrificing the original’s on-road composure. The footprint expands slightly for better leverage over obstacles, and axle articulation gains significantly for superior terrain conformity.

Luxury Meets Ruggedness: Interior and Protection Features

Inside, the cabin blends premium comfort with durability. Leather-trimmed seats with heating (in Black or Grey/Black), safari windows for expansive views, a premium sound system, carpet mats, and privacy glass come standard over the Trialmaster baseline. Roof racks, LED spotlights, and comprehensive trail armor—including underbody protection—shield vital components from abuse.

These vehicles appeal not just to adventurers but also to professional users like rescue services, aid organizations, and fleets in harsh conditions, with over 1,000 expressions of interest reported.

Pricing, Availability, and Warranty Details

Order books opened on July 8 for European customers, with Station Wagon pricing from €170,000 and Quartermaster from €171,000 (excluding VAT and taxes). First deliveries follow shortly after. Orders are placed via local Grenadier retailers, who coordinate with LeTech for conversion, homologation, and delivery. In Germany, LeTech handles end-to-end.

Warranty coverage includes the standard five-year, unlimited mileage from Ineos on mechanical components, plus a two-year warranty from LeTech on conversion parts. Global expansion to other markets awaits future announcements.

From Prototype to Production: A Quick Evolution

Prototypes wowed crowds at the 2024 Goodwood Festival of Speed, paving the way for rapid series approval. This collaboration underscores Ineos’s commitment to pushing Grenadier boundaries, building on its Land Rover Defender-inspired heritage while incorporating modern engineering.

Owners gain a vehicle optimized for deep sand, flooded paths, and jagged rocks, with retained highway manners. The portal setup’s durability has proven itself in testing across extreme scenarios.

Who Should Consider the Portal Axle Grenadier?

• Extreme overlanders seeking maximum capability without custom builds.
• Professional operators in rescue, mining, or humanitarian roles.
• Enthusiasts wanting factory-backed upgrades over aftermarket mods.

While the premium price reflects the exclusivity and engineering, it positions the Grenadier as a premium contender against vehicles like the Mercedes G-Class with portal options or military-grade 4x4s.

Frequently Asked Questions (FAQs)

What is the ground clearance gain from the portal axles?

The LeTech conversion adds 7.3 inches (186mm), elevating total clearance to 17.7 inches (450mm).

Are the engines modified in this edition?

No, both diesel and petrol BMW inline-six options remain unchanged, preserving original power and efficiency.
