Toyota Mega Cruiser: which version to buy
The Toyota Mega Cruiser was sold in one generation from 1996-01-01 to 2001-08-31, as an SUV 5-doors, with two catalogue versions. Both are named 4.1 AT. They share displacement, fuel, gearbox, drive, tank size, and ground clearance. The buying choice is not “which generation” — there is only one — but which 4.1 AT: the 155 hp tune or the 170 hp tune.

They share displacement, fuel, gearbox, drive, tank size, and ground clearance. The buying choice is not “which generation” — there is only one — but which 4.1 AT: the 155 hp tune or the 170 hp tune. The extra 15 hp and 39 Nm of the stronger unit come with 50 kg more kerb weight, a higher compression ratio, and peak torque and power at lower engine speed.
Specs that are the same on both 4.1 AT versions
Before ranking the two 4.1 AT cars, lock the numbers that do not change. Both use a 4104 cm³ Diesel engine, 4 cylinders in Inline layout, 4 valves per cylinder, Turbo, Front, transverse placement, and Distributed injection (multi-point). Bore and stroke are 108 × 112 on both. Fuel is Diesel. The gearbox is Automatic with 4 gears. Drive is AWD. The fuel tank is 108 litres. Ground clearance is 420 mm. Front suspension is Independent, spring; rear suspension is Independent, spring. Front brakes are Ventilated disc; rear brakes are Disc ventilated. Wheel sizes are not measured. Gross vehicle weight is not measured. CO2 is not measured. Eco class is not measured.
Those shared figures mean you are not choosing a different body, a different driveline, or a later generation. You are choosing a power and torque package on the same SUV 5-doors platform.
Generations: there is only one, so the comparison is inside it
1 generation (1996-01-01 – 2001-08-31) is the entire production window. Body: SUV 5-doors. Versions in this generation: 2, both labelled 4.1 AT. There is no second generation to “wait for,” and no restyling generation in the data. If a later Mega Cruiser existed, it is not in this catalogue set. The buy decision is therefore 155 hp 4.1 AT versus 170 hp 4.1 AT inside the same years.
Engines and specs: the two 4.1 AT versions side by side
| Version | hp | kW | rpm (power) | Nm | rpm (torque) | cm³ | Fuel | Cylinders | Layout | Boost | Gearbox | Gears | Drive | Compression |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| 4.1 AT (155 hp) | 155 | 114 | 3200 | 382 | 1800 | 4104 | Diesel | 4 | Inline | Turbo | Automatic | 4 | AWD | 17.8 |
| 4.1 AT (170 hp) | 170 | 125 | 3000 | 421 | 1600 | 4104 | Diesel | 4 | Inline | Turbo | Automatic | 4 | AWD | 18.4 |
The 4.1 AT (170 hp) makes 15 hp more than the 4.1 AT (155 hp): 170 − 155 = 15. In kilowatts that is 125 − 114 = 11 kW. Torque rises by 421 − 382 = 39 Nm. Compression rises by 18.4 − 17.8 = 0.6. Peak power arrives 200 rpm earlier (3000 vs 3200). Peak torque arrives 200 rpm earlier (1600 vs 1800). Displacement stays 4104 cm³ on both, so the extra output is a higher specific output of the same swept volume, not a larger engine.
Power per litre (hp ÷ 4.104 L):
- 4.1 AT (155 hp): 155 ÷ 4.104 ≈ 37.8 hp/L
- 4.1 AT (170 hp): 170 ÷ 4.104 ≈ 41.4 hp/L
That is about 3.6 hp/L more on the stronger 4.1 AT.
Performance and economy: what is measured, what is not
0–100 is not measured on the 4.1 AT (155 hp) and not measured on the 4.1 AT (170 hp). Top speed is not measured on both. City consumption is not measured. Highway consumption is not measured. Combined consumption is not measured. You cannot rank these two versions by sprint time, top speed, or mpg from this catalogue. Anyone selling a “faster” or “thirstier” Mega Cruiser using those claims is using numbers that are not in this data.
What you can rank is the measured output and mass. The 4.1 AT (170 hp) has more peak power, more peak torque, and those peaks at lower rpm. The 4.1 AT (155 hp) has less output and less kerb weight. Without a measured 0–100, the extra 15 hp and 39 Nm are the only performance argument for the stronger car; they are not a substitute for a timed run.
Dimensions and weight: 50 kg for 15 hp
| Version | Kerb weight | Gross weight | Ground clearance | Tank | Wheels |
|---|---|---|---|---|---|
| 4.1 AT (155 hp) | 2850 kg | not measured | 420 mm | 108 L | not measured |
| 4.1 AT (170 hp) | 2900 kg | not measured | 420 mm | 108 L | not measured |
The 4.1 AT (170 hp) is 2900 − 2850 = 50 kg heavier. Ground clearance does not change: 420 mm on both. Tank does not change: 108 L on both. Wheel size is not measured on both, so you cannot pick a version by tyre diameter from this table. Gross weight is not measured on both, so payload cannot be compared.
Mass per horsepower (kerb ÷ hp):
- 4.1 AT (155 hp): 2850 ÷ 155 ≈ 18.4 kg/hp
- 4.1 AT (170 hp): 2900 ÷ 170 ≈ 17.1 kg/hp
The heavier 4.1 AT (170 hp) still has the better mass-to-power figure: about 1.3 kg/hp less. The 50 kg penalty is smaller, in proportion, than the 15 hp gain: 50 / 2850 ≈ 1.8% more mass versus 15 / 155 ≈ 9.7% more power, and 39 / 382 ≈ 10.2% more torque.
Power-to-weight in hp per tonne of kerb mass:
- 4.1 AT (155 hp): 155 ÷ 2.850 ≈ 54.4 hp/t
- 4.1 AT (170 hp): 170 ÷ 2.900 ≈ 58.6 hp/t
Difference: about 4.2 hp/t in favour of the 4.1 AT (170 hp).
Which version to choose
There is no generation-to-generation upgrade path in this data. 1 generation is the whole model. The choice is only between two 4.1 AT diesels.
Choose the 4.1 AT (155 hp) if you want the lighter kerb mass (2850 kg), the lower compression ratio (17.8), and the same AWD, Automatic 4-speed, 108 L tank, and 420 mm clearance as the other car, without paying for the extra 15 hp. You give up 39 Nm and you accept a worse 18.4 kg/hp figure. You do not give up body type, drive, tank, or clearance. You also do not get a measured economy or 0–100 advantage, because those figures are not measured on this version as well.
Choose the 4.1 AT (170 hp) if you want the higher output of this catalogue pair: 170 hp / 125 kW at 3000 rpm and 421 Nm at 1600 rpm, compression 18.4, and the better 17.1 kg/hp and 58.6 hp/t arithmetic, while keeping 4104 cm³, Diesel, Turbo, Inline 4, AWD, and Automatic 4. The cost in the data is 50 kg extra kerb weight (2900 kg). There is no measured fuel-use penalty in the data — consumption is not measured — so you cannot treat the stronger tune as “thirstier” from these numbers. You also cannot treat it as quicker to 100 km/h, because 0–100 is not measured.
Do not choose by generation, restyle, mpg, 0–100, top speed, wheels, or gross weight. Generation count is 1. Consumption, 0–100, top speed, wheels, gross weight, CO2, and eco class are not measured on both 4.1 AT versions. The only measured differences that separate the two catalogue cars are power (155 vs 170 hp), torque (382 vs 421 Nm), power rpm (3200 vs 3000), torque rpm (1800 vs 1600), compression (17.8 vs 18.4), and kerb weight (2850 vs 2900 kg).
If you need a single default: the 4.1 AT (170 hp) is the version that improves every measured output metric in this set. It is 15 hp and 39 Nm stronger, peaks 200 rpm earlier for both power and torque, and still wins mass-per-horsepower despite 50 kg more kerb weight. The 4.1 AT (155 hp) is the version to take only when the lower mass and lower compression are the priority and the missing 15 hp / 39 Nm are acceptable. Both remain the same Toyota Mega Cruiser 1 generation SUV 5-doors AWD Automatic 4.1 AT — distinguished only by those numbers.
