There’s off-road capable. And then there’s this.

INEOS Automotive has just greenlit the production version of its portal-axled Grenadier — the Trialmaster X LETECH — developed in partnership with German off-road engineering maestros, LETECH GmbH. Orders open this July, starting in Germany and rolling out to European markets.

If you’ve ever looked at a stock Grenadier and thought, “That’s good, but can it ford a canal?” — this one’s for you.

Ground Clearance Like a Monster Truck

Portal axles aren’t just a bolt-on gimmick. They lift the entire differential higher by offsetting the hubs, pushing ground clearance to a phenomenal 450 mm — that’s +186 mm over stock. Fording depth shoots up from 800 mm to 1,050 mm. Translation: you could wade past stranded SUVs without a second thought.

This isn’t a factory “appearance package.” These rigs are built for real-world punishment — in deserts, jungles, mountains, and flood zones. And with over 1,000 customer enquiries, plus demand from aid agencies and rescue services, INEOS knew they had to move fast.

“With such strong interest from customers,” says Lynn Calder, CEO of INEOS Automotive, “we were very keen to respond quickly and collaborate on bringing the LETECH-enhanced Grenadier to market, starting with Europe.”

From Hambach to Stuttgart – Then Into the Wild

The conversion starts with the Grenadier or Quartermaster Trialmaster spec, fresh off the Hambach production line. From there, vehicles are shipped to LETECH HQ near Stuttgart, where the real work begins.

The key hardware includes:

• Portal axles with full heavy-duty five-link suspension
• 37-inch BFGoodrich Mud Terrains
• LETECH high-performance brake system
• Forged 8.5×18” Hutchinson Beadlock wheels
• Extended arches, running boards, and jacking points
• WARN Zeon 10 winch and dedicated mounting system
• LETECH roof rack with plank deck and marker LEDs
• Rear ladder with jerry can mount
• LED lightbar with DRLs
• LETECH spare wheel carrier
• Custom badging and scuff plates with ‘Trialmaster X LETECH’ branding

Still not hardcore enough? There’s an option list, too: integrated tyre pressure control system, MAXTRAX recovery gear, lockable drawer system, and rear work lights.

Diesel or Petrol — Pick Your Poison

The LETECH rigs come with your choice of BMW’s 3.0L inline-six in diesel (B57) or petrol (B58) flavours. Inside, they’re fitted to Trialmaster spec with heated leather seats (black or grey/black), safari windows, carpet mats, privacy glass and a premium sound system. Yes, you can get luxury and axle articulation.

Off-road geometry has been dialled in across the board — wider stance, longer travel, and improved articulation for better performance on gnarly terrain. Towing capacity? Still 3,500kg braked. Payload? Up to 642kg (Quartermaster, with gear). The GVM has been uprated to 4.2 tonnes.

Warranty? You Bet

The full INEOS five-year, unlimited-mileage mechanical warranty still applies. LETECH adds two years on their conversion hardware — including the portal axles and custom running gear. Not just a show pony. This thing’s built to work.

Orders & Availability

Prices start at around:

• €170,000 (ex VAT) for the Station Wagon
• €171,000 (ex VAT) for the Quartermaster

Orders are open now in Germany and across Europe via INEOS retailers, who will coordinate with LETECH directly. In Germany, LETECH handles the process end-to-end. International rollout is in the works, with more regions to follow.

“The Grenadier Trialmaster X LETECH is the perfect example of how the off-road fundamentals of the Grenadier makes it the ideal base for epic conversions,” says Calder. “We’re starting with Europe and quickly expanding to other key markets.”
