| Factory Tow Package | Optional |
The 2022 INEOS Grenadier launched with a braked towing capacity of 7,716 lbs (3,500 kg), supported by a full box-section ladder frame chassis shared with all subsequent model years. The heavy-duty solid beam front and rear axles contribute directly to towing stability under load. The Grenadier’s suspension — using a five-link layout with coil springs — is tuned to maintain axle articulation and wheel travel even when towing near rated capacity.
Towing Equipment and Setup
Tow Package and Hitch Interface
The INEOS Grenadier uses a proprietary vertical towing interface that accommodates multiple hitch formats, including fixed towballs, NATO pintle hooks, 50 mm jaw couplings, and Class III NAS hitches. Selecting the factory towing attachment ensures the rated tongue weight of 350 kg (772 lbs) is structurally supported by the chassis mounting point. Using non-approved aftermarket hitches may reduce tongue weight capacity and void towing-related warranty coverage.
Trailer Brake Controller
Any trailer exceeding 750 kg (1,653 lbs) gross trailer mass requires brakes on at least one trailer axle in most markets. A compatible electronic brake controller should be installed and calibrated to match the trailer’s loaded weight. Proper calibration reduces stopping distance and prevents trailer push during emergency braking.
Trailer Stability Assist
The Grenadier offers electronic Trailer Stability Assist in certain markets as a listed towing safety feature. This system monitors trailer sway and applies individual wheel braking to stabilize the combination. Trailer stability control does not substitute for proper weight distribution and tongue weight management.
Transmission Cooler
The 8-speed automatic transmission fitted to all Grenadier variants includes an integrated oil cooler as standard. Sustained high-load towing in hot ambient conditions places additional thermal stress on the transmission fluid. Monitoring transmission temperature and allowing cooling periods during extended grades protects the drivetrain.
Tire Load Ratings
Tires must carry a load rating sufficient for the vehicle’s Gross Vehicle Weight Rating (GVWR). When towing near maximum capacity, tire inflation pressures should follow the placard specifications for a fully loaded vehicle. Under-inflated tires reduce braking effectiveness and increase heat buildup during long towing runs.
Normal vs. Heavy Towing Equipment
| Item | Normal Towing (Under 3,500 lbs / 1,587 kg) | Heavy Towing (Above 3,500 lbs / 1,587 kg) |
|---|---|---|
| Hitch Type | Standard Class III towball | Class III NAS or pintle hook |
| Trailer Brakes | Not required (market dependent) | Required |
| Trailer Stability Assist | Recommended | Strongly recommended |
| Transmission Cooler | Standard unit sufficient | Monitor temperature on grades |
| Tire Pressure | Standard loaded pressure | Maximum placard pressure |
| Load Distribution | Standard tongue weight | 10-15% of trailer weight on ball |
Frequently Asked Questions
What is the maximum towing capacity of an INEOS Grenadier?
The INEOS Grenadier has a maximum braked towing capacity of 3,500 kg (7,716 lbs) across all model years from 2022 to 2026. This rating applies to the Station Wagon, Utility Wagon, and Quartermaster variants. The unbraked towing limit is 750 kg (1,653 lbs).
How much can an INEOS Grenadier tow with the tow package installed?
With the factory towing attachment installed, the Grenadier reaches its full rated capacity of 3,500 kg (7,716 lbs) for braked trailers. The vertical towing interface is designed to handle the maximum tongue weight of 350 kg (772 lbs) at the coupling point. Using a non-rated aftermarket towbar may reduce the permissible towing limit.
Does engine choice affect INEOS Grenadier towing capacity?
The rated maximum towing capacity of 3,500 kg (7,716 lbs) is identical for both the petrol and diesel engine options. The diesel engine produces more torque (406 lb-ft vs. 332 lb-ft), which benefits towing at lower engine speeds and on grades. The diesel engine’s additional weight, however, reduces the vehicle’s available payload compared to the petrol variant.
What trailer weight is safe for an INEOS Grenadier?
Trailer weight is safe when the gross trailer mass stays at or below 3,500 kg (7,716 lbs) with trailer brakes fitted and the tongue weight does not exceed 350 kg (772 lbs). The combined weight of the Grenadier and trailer must remain within the GCWR of 7,000 kg (15,432 lbs). Exceeding either limit stresses the chassis, transmission, and braking system beyond their design ratings.
Do I need a weight-distributing hitch for an INEOS Grenadier?
The INEOS Grenadier is not designed for weight-distributing hitch systems due to its rigid solid-axle suspension layout. The vertical towing interface accommodates conventional fixed towballs and pintle-style couplings suited to its rated tongue weight. Owners towing caravans or trailers near the 3,500 kg limit should use a trailer with a properly adjusted coupling height to maintain level tow vehicle stance.
What is the GCWR of an INEOS Grenadier?
The Gross Combined Weight Rating (GCWR) of the INEOS Grenadier is 7,000 kg (15,432 lbs). This figure represents the maximum allowable combined weight of the vehicle and the fully loaded trailer. Exceeding this combined mass limit compromises braking performance and chassis structural integrity.
Conclusion
The INEOS Grenadier maintains a consistent maximum towing capacity of 3,500 kg (7,716 lbs) across all model years from 2022 through 2026. This rating applies to both the Station Wagon and Quartermaster configurations and is unchanged between petrol and diesel engine options. The GCWR of 7,000 kg (15,432 lbs) and a tongue weight limit of 350 kg (772 lbs) define the outer boundaries of the vehicle’s towing system.
Payload capacity varies across configurations, ranging from 689 kg in a fully optioned diesel Trialmaster to 932 kg in lighter base variants. Operators should account for passenger weight, cargo, and fuel when calculating available payload before hitching a trailer. The factory towing attachment and Trailer Stability Assist system, where available, provide the strongest foundation for operating near rated towing limits.
