What is the fuel consumption of Toyota 2.4 diesel engine?
In general, the 2.4-litre Toyota diesel engines deliver around 6.5–9.0 liters per 100 kilometers in combined testing, depending on variant and configuration; real-world figures vary with load and driving style.
To understand what that means, note that Toyota's 2.4-litre diesel family spans several generations and models. The most common modern unit is the GD-series 2.4-litre turbo diesel (often labeled 2GD-FTV), used in models such as the Hilux, Fortuner, and Hiace in many markets. There are older 2.4-litre D-4D variants as well, which can show different consumption. Fuel economy is influenced by drivetrain, transmission, payload, terrain, and climate control use. Official ratings come from WLTP or EPA cycles and can differ by market; real-world economy may be higher or lower based on conditions.
Engine variants
2GD-FTV / GD-series 2.4-litre turbo diesel
Overview: A modern, common-rail turbo diesel with a variable nozzle turbo and dual overhead cams. It typically delivers around 150 hp and 400 Nm of torque in the Hilux and Fortuner. Efficiency gains over older designs come from direct injection, improved aerodynamics, and transmission pairing.
Fuel consumption range: In WLTP for 2WD configurations, combined numbers generally fall in the mid-to-upper 6 L/100 km range; for 4WD or automatic transmissions, numbers commonly rise to the high 7s or low 8s L/100 km. Real-world figures can shift by up to 1–2 L/100 km depending on load and driving style.
Older 2.4 D-4D variants
Overview: Earlier 2.4-litre D-4D units were used in some Hilux/Hilux-based variants and other Toyota vans. They rely on older common-rail or indirect injection technology and typically show higher fuel consumption than modern GD-series units under similar conditions.
Fuel consumption range: Expect roughly 7.5–9.5 L/100 km in combined testing for typical configurations; real-world numbers can vary with load, terrain, and maintenance condition.
How configuration affects fuel economy
Before listing typical numbers, note that your final economy depends heavily on how the vehicle is equipped and used. The following factors tend to push fuel consumption up or down.
- Drivetrain: 2WD vs 4WD typically adds weight and drivetrain losses, increasing consumption in 4WD variants.
- Transmission: Manual vs automatic; some automatics (with gear-step optimization) can improve or worsen economy depending on rpm at cruising speed.
- Payload and roof load: Heavy loads increase energy required to move the vehicle; aerodynamics are also affected by roof racks, spoilers, and luggage.
- Terrain and driving style: City driving with frequent stops, steep hills, and aggressive acceleration raises consumption versus steady highway cruising.
- Climate control usage: Air conditioning usage can raise instantaneous fuel use, particularly in hot climates.
Conclusion: Expect a range of about 6.5–9.0 L/100 km for latest GD-series 2.4 diesel in common configurations, with higher numbers possible under load or when using 4x4 and automatic transmissions. For precise figures, consult the official WLTP/EPA ratings for your exact market and model year, or check the vehicle’s on-board computer and trip meter after a few tanks of fuel.
Real-world expectations by model (illustrative ranges)
The following are approximate ranges observed in various markets for popular 2.4-litre Toyota diesel models. Individual results vary by year, trim, and driving conditions.
- Hilux/GD-series 2.4L, 2WD manual: roughly 6.5–7.5 L/100 km on highway-heavy routes; urban/stop-and-go can push toward 7.5–8.5 L/100 km.
- Hilux/GD-series 2.4L, 4x4 or automatic: roughly 7.5–9.0 L/100 km depending on load and terrain.
- Hiace 2.4L van: typically around 8.0–9.5 L/100 km depending on passenger/cargo load and driving style.
Note: These numbers are approximate ranges to illustrate typical orders of magnitude and may not reflect a specific market or model year. Always refer to the official WLTP/EPA figures for your vehicle’s exact specification and test cycle.
Summary
There is no single universal fuel-economy figure for Toyota’s 2.4-litre diesel engine. Modern GD-series 2.4L turbo diesels tend to deliver better efficiency than older D-4D variants, but economy varies widely with drivetrain, transmission, payload, and driving conditions. For the most accurate figure, consult the official WLTP or EPA ratings for your exact model, year, and market, and consider real-world testing over several tanks to gauge typical performance.
