What is the fuel consumption of a Lexus LX450D?
The Lexus LX450d typically records a combined fuel consumption around 8.8–9.4 liters per 100 kilometers on WLTP testing, with real-world results varying by market, driving style, and conditions.
About the LX450d and how fuel figures are published
The LX450d is the diesel variant of Lexus’s full-size LX, built on the Toyota Land Cruiser 300 platform. It uses a 3.3-liter twin-turbo diesel and is primarily offered outside the United States, where the model lineup differs. Official economy figures are published under WLTP in many markets, and can differ from older cycles or other regions.
Official WLTP figures by region
Below are typical WLTP figures used in many markets. They illustrate the expected efficiency split between city, combined, and highway driving.
- Combined: 8.8–9.4 L/100km
- City: 9.5–11.0 L/100km
- Highway: 7.8–8.6 L/100km
Note: These ranges reflect market and model-year variations, tire choices, drivetrain configuration, and test-cycle differences.
Real-world driving and caveats
In everyday use, the numbers can vary widely. Factors such as payload, towing, off-road work, climate control, and driving style can push observed consumption above or below WLTP figures. Diesel engines often perform closer to their WLTP highway numbers on long highway drives and rise in urban, stop-and-go conditions.
What affects fuel consumption in practice
Several real-world factors play a big role in actual fuel economy for the LX450d. Understanding them can help set expectations and optimize efficiency.
- Payload and towing load
- Terrain and driving terrain (hills, off-road, sand, etc.)
- Tire type, pressure, and rolling resistance
- Climate control usage and auxiliary electrical loads
- Driving behavior, including acceleration style and average speed
Owners often report that sustained highway cruising yields lower consumption than city-centre driving, especially when the vehicle is lightly loaded and tires are properly inflated.
Where to find the exact numbers for your market
To get the precise figures for your region and trim level, check the official Lexus specification sheets for your country, the WLTP-certified window sticker, and contemporary press materials. Market-specific data can vary due to local testing protocols and available equipment.
Summary
The Lexus LX450d tends to hover around the high 8s to low 9s L/100km in WLTP terms, with real-world results influenced by load, terrain, and driving habits. Prospective buyers should consult the exact figures for their market and review owner experiences to gauge what to expect in daily use.
What years to avoid Lexus LX 470?
There are no specific LX470 years to definitively "avoid," as the model is known for high reliability. However, some early models (pre-2003) may have transmission issues related to earlier gearbox design, and the 2001 model has some documented issues with idle and startup. The 2000 model year is mentioned for occasional cold-start problems and the potential need to replace an engine start-related part.

Specific model years to be aware of
- 2000: A few complaints about the car failing to start on very cold days.
- 2001: Some owners report issues with idle stalling and unstable RPMs.
- Pre-2003 (non-facelift): While still reliable, some pre-2003 models had a four-speed automatic transmission (A343F) that was more prone to transmission backlash issues than the improved five-speed (A750F) in later models.
General advice
- Check for maintenance history: Since the LX470 is a capable off-road vehicle, some wear and tear can occur, especially on the drivetrain.
- Look for signs of wear: Check for backlash in the transmission and front hubs, which can be exacerbated by demanding use and may require expensive repairs.
- Consider the benefits of later models: Post-2003 facelift models feature a stronger five-speed automatic transmission and a more robust gearbox, making them a great option.
- Don't let minor issues deter you: For a luxury SUV known for its durability, many of the issues mentioned (like the 2000 cold-start problem) are relatively minor and can be addressed with proper maintenance. Some issues are only reported after very high mileage, such as a 2005 model requiring a new brake master cylinder at 300,000 miles.
