What is the fuel consumption of Land Cruiser V8 engine?
In commonly sold gasoline Land Cruisers, V8 models typically return around 15 miles per gallon (mpg) combined, with city driving near 13–14 mpg and highway driving near 17–18 mpg. The older 4.7-liter V8 usually falls in a similar band, while the newer 5.7-liter V8 tends to hover around the same overall figure but with different driving characteristics. Diesel variants—where offered in certain markets—often achieve higher highway efficiency, though official U.S. numbers are scarce.
Origins of the V8 options in the Land Cruiser line
The Land Cruiser’s gasoline V8 history centers on two main engines used across generations: the 4.7-liter V8 (2UZ-FE) in the 100 Series and the 5.7-liter V8 (3UR-FE) in the 200 Series. A diesel V8 option was also available in some markets (notably a 4.5-liter turbocharged design) but is less common in North America.
4.7-liter V8 (2UZ-FE) — Land Cruiser 100 Series (1998–2007)
The following figures reflect typical EPA-era ranges for U.S. and similar markets during the 1998–2007 period, with variations by drivetrain and model year.
- City: 13–14 mpg
- Highway: 17–18 mpg
- Combined: 15–16 mpg
These numbers illustrate the mid-2000s reality of a heavy, full-size SUV with a large naturally aspirated V8. Real-world results could vary based on handling, cargo, and terrain.
5.7-liter V8 (3UR-FE) — Land Cruiser (J200, 2008–present in many markets)
The 5.7L V8 has powered the modern Land Cruiser through most of the 2010s and into the 2020s, delivering substantial torque for off-road capability. EPA ratings for typical configurations in their era commonly fall in this range.
- City: 13–14 mpg
- Highway: 18–19 mpg
- Combined: 15–16 mpg
As with the 4.7L, real-world numbers depend on transmission, drivetrain (2WD vs 4WD), payload, and driving style. The 5.7L often behaves noticeably differently from the 4.7L in terms of throttle feel and acceleration, which can influence perceived efficiency.
Diesel and other V8 variants in international markets
Beyond the gasoline V8s, some international markets offered a diesel V8 option (not widely sold in the U.S.). These engines typically provide better highway economy thanks to higher torque at lower revs, but official EPA-style numbers are rarely published for these variants. Where available, diesel V8s generally show higher highway efficiency but similar or slightly better overall efficiency depending on load and terrain.
Market-specific figures vary considerably, and diesel variants may not be offered in all regions or model years. If you’re evaluating a specific truck, check the exact model year’s fuel economy data from the local Toyota publication or EPA labeling for that vehicle.
- Diesel V8 (where available): typically higher highway efficiency than gasoline V8s, but exact figures depend on market and configuration
Because diesel engines and testing standards differ by country, it’s best to refer to the official local ratings when considering a diesel-equipped Land Cruiser in your region.
What to expect in real-world driving
Actual fuel economy for any Land Cruiser V8 will depend on factors such as vehicle load, driving terrain (hills, deserts, highways), maintenance, tire choice, and driving style. Off-road use or heavy towing can significantly lower economy versus highway-only cruising.
Drivers who prioritize efficiency often balance payload and comfort with driving habits to approach the lower end of these ranges, while spirited or off-road driving will typically sit higher in terms of fuel consumption per mile driven.
Summary
Across generations, gasoline Land Cruisers with V8 powertrains have generally delivered around 15 mpg combined, with city figures in the low to mid-teens and highway results in the upper teens. The 4.7-liter and 5.7-liter V8s offer different driving personalities, but both sit in a similar overall efficiency band for typical on-road use. Diesel V8 variants, where offered, can improve highway efficiency, though exact numbers vary by market and year. For precise figures, consult the EPA ratings or the official specifications for the exact year and region of the vehicle you’re considering.
Does a V8 engine consume more fuel?
Yes, a V8 engine generally consumes more fuel than a V6 engine due to its larger size, more cylinders, and greater displacement, which means it processes more air and fuel. While a V8 can produce more power and torque, leading to better acceleration and hauling capabilities, its higher fuel consumption makes a V6 a more fuel-efficient option for many drivers, as explained in sources like Capital Chrysler Dodge Jeep Ram of Indian Trail, Tutton Chrysler Dodge Jeep RAM of Jasper, and Nissan USA.
Reasons for higher fuel consumption in V8 engines
- Larger displacement: A V8 engine has a larger volume for air and fuel to mix and combust with each cycle compared to a V6.
- More cylinders: More cylinders mean more combustion events per rotation, leading to higher overall fuel use, especially at idle and low speeds, according to Reddit users.
- More friction: A V8 engine has more moving parts, which can lead to increased internal friction and heat loss compared to a smaller V6, further contributing to higher fuel use, as noted on Quora.
Where a V8 might be comparable or even more efficient
- Heavy loads: In some trucks or heavy vehicles, a V8's torque can allow it to operate in a lower, more efficient gear and at lower RPMs when under a heavy load, potentially matching the fuel economy of a smaller engine that is working much harder, say Reddit users.
Trade-offs to consider
- Performance: A V8 engine delivers more power and torque, making it better for performance and towing.
- Efficiency: A V6 engine is generally more fuel-efficient, provides better gas mileage, and has lower maintenance costs due to fewer moving parts, according to Nissan USA.
What is the fuel consumption of Toyota Land Cruiser 100 4.7 V8?
Fuel efficiency
Most country drives will see a return of 16-18 litres/100 km, while in town you'll be doing very well to better 20 litres/100 km, and could easily reach 25 litres/100 km.
What is the fuel economy of a Land Cruiser V8?
While Toyota's estimates are around 14.7L/100km for city use and 10.5L/100km on highways, your actual figures may be slightly higher, especially on demanding routes. Many GCC drivers have noted figures in the range of 16.2-18.5L/100km in city conditions and 11.8-13.4L/100km on highways.
Which is better, Land Cruiser V6 or V8?
V8 is only required if you do TOWING or for HEAVY OFF ROADING as these require higher torque otherwise better go with V6 for better fuel efficiency and lower maintenance.
