Ineos Grenadier: which version to buy
There is one Ineos Grenadier generation (from 2022-06-01, still in production) and two 3.0 AT versions of the same SUV 5-doors body: a Diesel 3.0 AT with 249 hp / 550 Nm, and a Gasoline 3.0 AT with 286 hp / 450 Nm. The petrol 3.0 AT is 37 hp stronger, 1.3 s quicker to 100 km/h (8.6 vs 9.9), and 75 kg lighter at the kerb (2665 vs 2740 kg).

The petrol 3.0 AT is 37 hp stronger, 1.3 s quicker to 100 km/h (8.6 vs 9.9), and 75 kg lighter at the kerb (2665 vs 2740 kg). The diesel 3.0 AT has 100 Nm more torque, 38 g/km less CO2 (308 vs 346), and the same 160 km/h top speed, 8-speed Automatic, AWD, 264 mm ground clearance, Euro 6, and 3500 kg gross weight. Combined fuel consumption, tank size, and wheel size are not measured for either version, so they cannot decide the choice.
Ineos Grenadier engine options: two 3.0 AT versions, not two cars
Both listed engines share the catalogue name 3.0 AT. Distinguish them by power, or the modification pages collide.
The 3.0 AT at 249 hp (183 kW at 3250-4200 rpm) is Diesel, 2993 cc, 6 cylinders, Inline, Turbo, Front, longitudinal. Peak torque is 550 Nm at 1250-3000 rpm. Compression ratio is 16.5. Bore and stroke are 84 x 90. Fuel is Diesel. Fuel system is not measured. Gearbox is Automatic, 8 speeds. Drive is AWD.
The 3.0 AT at 286 hp (210 kW at 4750 rpm) is Gasoline, 2998 cc, 6 cylinders, Inline, Turbo, Front, longitudinal. Peak torque is 450 Nm at 1750-4000 rpm. Compression ratio is 11. Bore and stroke are 82 x 94.6. Fuel is 95. Fuel system is Direct injection (direct). Gearbox is Automatic, 8 speeds. Drive is AWD.
Displacement differs by 5 cc (2998 − 2993). Cylinder count, layout, boost, engine position, gearbox type, gear count, and drive are identical. The choice is not “six versus eight” or “auto versus manual”; it is diesel torque versus petrol power on the same AWD Automatic layout.
Ineos Grenadier specs: version table
| Version | hp | Nm | Displacement (cc) | Fuel | Cylinders | Layout | Boost | Gearbox | Drive |
|---|---|---|---|---|---|---|---|---|---|
| 3.0 AT (249 hp) | 249 | 550 | 2993 | Diesel | 6 | Inline | Turbo | Automatic (8) | AWD |
| 3.0 AT (286 hp) | 286 | 450 | 2998 | Gasoline | 6 | Inline | Turbo | Automatic (8) | AWD |
Ineos Grenadier horsepower and torque: what the extra 37 hp costs in newton-metres
Specific output:
- 3.0 AT 249 hp: 249 / 2.993 ≈ 83.2 hp per litre; 550 / 2.993 ≈ 183.8 Nm per litre.
- 3.0 AT 286 hp: 286 / 2.998 ≈ 95.4 hp per litre; 450 / 2.998 ≈ 150.1 Nm per litre.
The petrol 3.0 AT makes about 12.2 hp per litre more. The diesel 3.0 AT makes about 33.7 Nm per litre more. Absolute gap: +37 hp and −100 Nm if you take petrol instead of diesel.
Peak power arrives later on petrol (4750 rpm versus the diesel band 3250-4200). Peak torque starts later on petrol (1750 rpm versus 1250). For low-rpm pull, the 3.0 AT 249 hp diesel is the denser torque engine. For peak horsepower, the 3.0 AT 286 hp petrol is the denser power engine.
Compression: 16.5 (diesel) versus 11 (petrol). That is a 5.5-point gap, consistent with Diesel versus Gasoline and 95 fuel. It is not a reason to mix the two 3.0 AT names.
Ineos Grenadier 0-100 and top speed
- 3.0 AT 249 hp: 9.9 s to 100 km/h, 160 km/h maximum.
- 3.0 AT 286 hp: 8.6 s to 100 km/h, 160 km/h maximum.
The petrol version is 1.3 s faster to 100 km/h. Top speed is the same 160 km/h, so extra horsepower does not buy a higher listed maximum. If the buying question is “which is quicker off the line,” the 3.0 AT 286 hp wins on the only acceleration figure given. If the question is “which goes faster at the top,” the data say neither does.
Ineos Grenadier mpg: not measured; CO2 is the only economy number
City, highway, and combined consumption are not measured for both 3.0 AT versions. Tank capacity is not measured. Wheel size is not measured. Do not treat missing mpg as “there is no consumption”; it is simply not in this dataset.
CO2 is measured:
- 3.0 AT 249 hp: 308 (Euro 6).
- 3.0 AT 286 hp: 346 (Euro 6).
Petrol emits 38 more CO2 units than diesel on this sheet. Eco class is the same Euro 6. If the buying filter is listed CO2, diesel 3.0 AT 249 hp is the lower figure. If the filter is mpg, both versions fail the same way: not measured.
Ineos Grenadier specs weight and payload
Kerb and gross:
- 3.0 AT 249 hp: kerb 2740 kg, gross 3500 kg. Payload by subtraction: 3500 − 2740 = 760 kg.
- 3.0 AT 286 hp: kerb 2665 kg, gross 3500 kg. Payload by subtraction: 3500 − 2665 = 835 kg.
The petrol 3.0 AT is 75 kg lighter at the kerb and has 75 kg more payload to the same 3500 kg gross. Mass per horsepower:
- Diesel: 2740 / 249 ≈ 11.0 kg per hp.
- Petrol: 2665 / 286 ≈ 9.3 kg per hp.
The petrol 3.0 AT carries about 1.7 kg less per horsepower. Ground clearance is 264 mm on both. Front brakes are Ventilated disc on both; rear brakes are Disc on both. Front and rear suspension are Dependent, spring on both. Weight and payload change with the engine; clearance, brakes, and suspension labels do not.
Ineos Grenadier dimensions: what this sheet does not give
Length, width, height, wheelbase, inches, millimetres, and feet are not measured. Size comparison with other models is not measured. The measured size-related figures here are kerb weight, gross weight, and 264 mm clearance. A dimensions-in-inches or dimensions-vs-Defender decision cannot be made from these data.
Ineos Grenadier generations: one generation, no restyle to pick
1 generation, key 7410, from 2022-06-01, end date not measured (still listed without a stop). Body: SUV 5-doors. Modifications: 2, both 3.0 AT, both from 2022-06-01, both without a stop date.
There is no second generation and no restyling generation in the data. You cannot buy a “later Grenadier” by generation number. The only version choice is inside this generation: 3.0 AT 249 hp Diesel versus 3.0 AT 286 hp Gasoline.
Quartermaster, used-market trims, engine swaps, and engine-bay upgrades are not measured here. Reliability is not measured. Interior is not measured. Price and for-sale listings are not measured and are not used below.
Which version to choose
Choose the 3.0 AT 249 hp Diesel if you want the higher torque (550 Nm vs 450), the earlier torque band (1250-3000 vs 1750-4000), the lower CO2 (308 vs 346), and you accept 9.9 s to 100 km/h, 2740 kg kerb, 760 kg payload to 3500 kg, and 83.2 hp per litre. Fuel is Diesel. Fuel system is not measured. Combined mpg is not measured.
Choose the 3.0 AT 286 hp Gasoline if you want the higher power (286 hp vs 249), the lighter kerb (2665 kg vs 2740), the higher payload to the same 3500 kg (835 kg vs 760), the lower mass per hp (≈9.3 vs ≈11.0 kg/hp), and the quicker 8.6 s to 100 km/h. You give up 100 Nm, take 346 CO2 instead of 308, and run 95 with Direct injection (direct). Combined mpg is still not measured. Top speed remains 160 km/h.
Do not choose by name alone. Both versions are labelled 3.0 AT. The 5 cc displacement gap does not separate them in a catalogue search; 249 hp versus 286 hp does.
Do not choose by generation. There is one generation from 2022-06-01. Nothing in the data records a later generation that changed engines, weight, or clearance.
Do not choose by mpg, tank, wheels, or price. Those values are not measured. The arithmetic that is allowed is only on the numbers above: +37 hp, −100 Nm, −1.3 s to 100, −75 kg kerb, +75 kg payload, +38 CO2, same 160 km/h, same AWD, same 8-speed Automatic, same 264 mm clearance, same Euro 6, same 3500 kg gross.
If the job is towing-style pull and lower listed CO2, the diesel 3.0 AT 249 hp is the version the numbers favour. If the job is quicker 0–100, more hp per litre, and more payload inside 3500 kg, the petrol 3.0 AT 286 hp is the version the numbers favour. That is the whole choice on this sheet.
