Previewed as a prototype at the 2024 Goodwood Festival of Speed, the portal-axled Grenadier has now been approved for series production.

Developed and supplied exclusively by LeTech, the conversion is based on Grenadier and Quartermaster Trialmaster vehicles, which are transferred from the Hambach plant to LeTech’s facilities near Stuttgart.

Here the vehicles are fitted with a new heavy-duty five-link front and rear suspension layout, portal axles with wheel hubs offset from the main axle and larger 37” BFGoodrich mud terrain off-road tyres. The drivetrain remains unchanged.

The conversion package also includes 8.5×18” ET55 Hutchinson Industries forged beadlock alloy wheels, high performance brakes, extended wheel arches, off-road running boards with jacking points, and front winch mounting system with a 4.5t capacity winch.

Additionally, there is a multi-function rear ladder with jerry can mount, roof rack with planking and LED marker lights, lightbar with six x LED spotlights, spare wheel carrier and ‘Trialmaster X LeTech’ door sill scuff plates and A-pillar badging.

LeTech also offers a fully integrated tyre pressure control system, Loadspace drawer box with two lockable drawers, LED rear work lamps and a Maxtrax sand ladder kit.

Available with either 3.0-litre turbocharged inline-six-cylinder BMW B57 diesel or B58 petrol engines, all models come with a leather interior with heated front seats in either black or grey/black, safari windows, premium sound system, carpet floor mats and privacy glass over and above the usual Trialmaster standard equipment.

The modifications increase ground clearance by 186mm to 450mm and wading depth from 800mm to 1.05m. They also result in a wider vehicle footprint.

The Grenadier’s towing (3,500kg braked trailer) capacity is retained, and payload capacities (up to 540kg for station wagon; up to 642kg for Quartermaster) are enabled by uprating the vehicles’ GVM to 4.2t. The standard five-year, unlimited mileage mechanical factory warranty remains, and LeTech offers a two-year warranty on the conversion parts.

“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,” comments Lynn Calder, CEO, Ineos Automotive.

“With such strong interest from customers (over 1,000 registrations of interest) we were very keen to respond quickly and collaborate on bringing the LeTech-enhanced Grenadier to market, starting with Europe and quickly expanding to other key markets.”

LeTech will manage vehicle order, the full conversion, individual homologation for road use and shipping to the end customer’s retailer for local registration and delivery. Order books are open now, with prices starting from around €170,000 for the Grenadier station wagon and €171,000 for the Quartermaster. All prices exclude VAT.
