We take a look at 79 Series V8 Fuel Consumption
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.
Frequently Asked Questions
What is the fuel consumption of a 79 Series V8?
Highway 11-13 L/100km. Urban 14-16 L/100km. Towing 18-22 L/100km. Off-road in low range 25-35 L/100km.
Is the V8 more economical than the 2.8L?
No. The 2.8L is approximately 15-20% more economical unladen. The V8 is preferred for pulling character rather than economy.
How can I improve V8 fuel consumption?
Correct tyre pressure. Regular air filter service. Highway speed 100 km/h vs 110 saves 1-2 L/100km. Smooth driving style.
