We take a look at 79 Series V8 Fuel Consumption

Quick Answer: Real-world fuel consumption on the Toyota Landcruiser 79 Series V8 1VD-FTV 4.5L turbo-diesel (sold 2007 to late 2024): highway sealed road unladen ~11-13 L/100km, urban driving ~14-16 L/100km, touring with modest mods ~13-15 L/100km, towing 3,000 kg caravan at 90 km/h ~18-22 L/100km, full off-road work in low range ~25-35 L/100km. Toyota's claimed combined cycle ~10.7 L/100km (manual) is a rare achievement in real-world use. The new 2.8L 1GD-FTV is approximately 15-20% more economical unladen.

The V8 79 Series fuel consumption is one of the platform's most-discussed practical aspects. This guide covers realistic figures.

1. Highway Sealed Road, Unladen

11-13 L/100km is typical for a stock V8 79 Series Dual Cab on sealed highway at 100-110 km/h. Single Cab marginally better due to lighter kerb. Manual transmissions slightly more economical than auto on steady-state cruising.

2. Urban Driving

14-16 L/100km in suburban stop-start use. The V8 is at its least efficient in city traffic - large displacement, conservative throttle calibration and high gear ratios combine to push consumption up.

3. Touring with Modifications

13-15 L/100km with bull bar, snorkel, modest suspension lift and touring tyres. Each accessory adds drag and weight but the V8 absorbs the impact better than smaller engines would.

4. Towing

18-22 L/100km towing a 3,000 kg caravan at 90 km/h. Heavier loads or steeper terrain push toward 24-28 L/100km. The V8's wide torque band keeps consumption manageable even under heavy tow - the truck does not have to be revved hard.

5. Off-Road in Low Range

25-35 L/100km in sustained low-range work. Sand driving with low tyre pressures, heavy mud and rock crawling all push consumption higher because the engine spends time at relatively high rpm at low road speed.

6. V8 vs 2.8L Comparison

The new 2.8L 1GD-FTV is approximately 15-20% more economical unladen. Highway typically 9.5-11 L/100km. Towing margin narrows to 10-12% improvement. Combined cycle Toyota figure ~9.5 L/100km.
