What is the fuel consumption of the lx450d?
Typically around 10 L/100 km on a combined cycle, which equates to roughly 23–25 mpg UK. This provides a general reference for the LX450d’s fuel efficiency in standard testing.
The LX450d is Lexus’s diesel variant of its large LX SUV, powered by a 4.5-liter turbo-diesel V8 and sold in several international markets. Fuel economy numbers vary by market and by the regulatory test cycle used (for example WLTP or the older NEDC). The model is not offered in the United States, so there is no EPA rating for this variant. The figures below summarize common market values and note real‑world considerations.
Fuel economy by market and test cycle
Note: Official numbers are expressed on different test cycles and can differ from real-world driving. The ranges below reflect typical published figures for common markets and cycles.
- WLTP combined: about 10.0–11.0 L/100 km (roughly 25–28 mpg UK)
- NEDC (older European cycle): about 9.0–9.8 L/100 km (roughly 29–35 mpg UK, depending on configuration)
- Real-world driving: commonly around 12–14 L/100 km for mixed use; higher with heavy payload, towing, or frequent stop-and-go conditions
- North America: LX450d was not offered in the United States; no EPA rating exists for this variant
In practical terms, drivers can expect that highway cruising on the LX450d tends to approach the lower end of its WLTP range, while urban driving or towing situations push consumption higher. Real-world results will vary based on factors such as load, terrain, and maintenance.
Factors that affect fuel economy
- Driving style and speed consistency (aggressive acceleration increases consumption)
- Vehicle load and towing (heavier payloads raise fuel use)
- Terrain and route (hills and rough terrain raise fuel consumption)
- Tyre selection and wheel size (tyres with higher rolling resistance can raise use)
- Maintenance and condition (regular servicing, clean filters, and proper tyre pressure help economy)
Overall, the LX450d delivers a reference point around 10 L/100 km in standardized tests, with real-world figures commonly higher depending on usage. For the most accurate numbers, check local Lexus specifications and regulatory data for your country.
Summary
The LX450d’s fuel consumption typically centers around 10 L/100 km on standard combined testing, with real-world figures often higher depending on driving conditions, payload, and towing. Availability varies by market, and there is no EPA rating because the model isn’t sold in the United States. For precise figures, refer to your local Lexus brochure or regulatory publications.
