⚙️ Engine Specifications

Engine Type Diesel:

Likely 2.8L (3L) or 2.4L (2L) naturally aspirated diesel engines, or potentially the 3.0L (14B) diesel. Turbocharged variants may also exist.

Engine Type Petrol:

Possible petrol engines include 1.6L (AB20) or 2.2L (4Z) overhead camshaft engines.

Horsepower Range Diesel:

Typically 70-90 hp for 2.4L/2.8L diesel engines.

Horsepower Range Petrol:

Likely 75-95 hp for 1.6L/2.2L petrol engines.

Torque Characteristics:

Diesel engines offer strong low-end torque, crucial for off-road and towing.

Diesel Fuel System:

Typically rotary injection pumps (e.g., Bosch VE) with mechanical injectors.

Petrol Fuel System:

Carbureted or early electronic fuel injection systems.

🔧 Transmission

Type Standard:

5-speed manual transmission

Type Optional:

4-speed automatic transmission (less common, but potentially available on some F77 models)

Drivetrain Configuration:

Part-time four-wheel drive with manual front hub engagement or automatic locking hubs. High-range (2H) and low-range (4H, 4L) gearing.

📐 Dimensions

Wheelbase Short Wheelbase:

Approx. 2,300 mm (90.6 inches) for SWB variants

Wheelbase Long Wheelbase:

Approx. 2,600 mm (102.4 inches) for LWB variants (common for F77 models)

Ground Clearance:

Generally good, often exceeding 200 mm (7.9 inches) depending on tire size and suspension.

Curb Weight:

Varies significantly by body style and engine, typically ranging from 1,400 kg to 1,800 kg (3,086 lbs to 3,968 lbs).

🛡️ Safety Features

Crash Test Results:

Limited official crash test data available for this era and market. Focus would have been on structural integrity for off-road use rather than modern impact safety standards.

Active Safety:

Four-wheel drive system enhances traction; ABS was not standard in early models and may have been an option on later ones.

Passive Safety:

Seat belts, reinforced chassis and body structure.

💡 Technology Features

Infotainment System:

Basic AM/FM radio, optional cassette player. Limited to fundamental audio playback without modern features like Bluetooth or touchscreens.

Driver Assistance Features:

Minimal to none. Features like ABS were optional or absent. Focus is on mechanical function rather than electronic assistance.

Connectivity Options:

None beyond basic 12V power outlet for accessories.

🔧 Maintenance

Typically every 5,000-7,500 km (3,000-5,000 miles) or 6 months, depending on driving conditions.

Oil Change Interval Petrol:

Typically every 7,500-10,000 km (5,000-6,000 miles) or 6 months.

Transmission Fluid Change:

Manual: Inspect every 20,000 km (12,000 miles), change as needed. Automatic: Every 40,000-50,000 km (25,000-30,000 miles).

Engine Oil Diesel:

API CD or higher, SAE 10W-30 or 15W-40 depending on climate.
