Powerful new diesel engines
The powerful new diesel engine range in the 007 Toyota Hilux, and the option of automatic transmission on the new 3.0 D-4D engine, offers customers a broad choice of powertrain to suit their work and leisure needs. The new engines are refined and quiet, with high torque output for maximum power both on- and off-road. They deliver smooth power throughout the rev range and, thanks to high efficiency turbochargers, balance this increased power output with low fuel consumption and reduced emissions.
Both engines comply with Euro IV emissions and have been integrated into the Hilux range to enhance driving pleasure, especially in the growing leisure pick-up market.
2007 Toyota Hilux
Outstanding performance: 3.0 D-4D
The new 3.0-litre D-4D in the 007 Hilux is the latest derivative of the renowned diesel engine which also appears in the flagship Toyota Land Cruiser. It features second-generation common-rail technology, variable nozzle turbocharger and a swirl control system for maximum efficiency.
Equipped with this hi-tech advanced engine, the Toyota Hilux is the ultimate leisure and adventure vehicle with outstanding off-road capability while also delivering refined on-road driving pleasure with low levels of noise, vibration and harshness.
In its latest derivative the 3.0 D-4D ( KD-FTV engine) delivers 171 DIN hp (126kW) of power at 3600 rpm and has a flat torque output of 343 Nm right across the engine range from 1400 to 3400 rpm. This engine gives the 007 Toyota Hilux at top speed of 170 km/h (M/T) while delivering excellent fuel economy of 8.3 l/ 00km (M/T) on the combined ECE-cycle.
The 3.0-litre engine is a technically advanced iron-alloy block unit with an aluminium alloy cylinder head and four valves per cylinder. Two separate input ports of different shapes help promote fuel mix and optimise swirl.
The five journals crankshaft has eight balancing weights and there are two counter-rotating balancing shafts to reduce engine vibration, contributing to the excellent driving pleasure. The engine mounts, front and rear, have been optimised to reduce vibration transmission to the chassis and enhance ride comfort.
The second-generation, common rail system develops a high injection pressure, allowing the use of injector nozzles with smaller diameter holes to create a more homogenous air-fuel mix, improving the efficiency of the combustion process. This translates into more performance with
lower emissions and lower fuel consumption.

Over a wide range of engine speeds (800- 3000 rpm) the common-rail system performs a double pilot injection per cycle (prior to the main injection), distributing the most suitable amount of fuel with three distinct injections each. This reduces the combustion noise and engine vibration, from this high performance diesel.
One key to the impressive power and torque output of the 3.0-litre D-4D is the sophisticated, variable vane, turbocharger which balances exhaust back pressure and boost pressure based on the precise demands of the engine. Toyota uses an electric DC (direct current) motor to activate the variable nozzle vane mechanism, instead of the conventional step motor. The result is sharper response from the turbocharger, particularly at lower speeds and higher precision of vane activation.
The engine also benefits from a Swirl Control System. Each cylinder is supplied with air/exhaust gas mixture through two different independent ducts. Butterfly valves operated by the Swirl Control System can shut off one of these ducts according to the engine speed and load, increasing the mixture’s swirl rate.
Further improvements to the emissions performance, particularly at cold start, are achieved by fitting an Exhaust Gas Recirculation (EGR) cooler with integrated bypass and a switching valve to optimise EGR gas temperature.
At low engine speeds this device improves the air-fuel mixture, thus further increasing torque availability at low speeds along with lower emissions. The new 3.0 D-4D engine will be exclusively available for the 4x4 Double Cab body style in SR
grade and above.
Power boosted: 2.5 D-4D
More power, reduced emissions and lower noise levels are key enhancements to the 2.5-litre D-4D engine that remains at the heart of the Toyota Hilux appeal and have made it a best-seller worldwide. The power-boosted .5 D-4D, with remarkable torque output, will give the 2007 Hilux more performance and more driving pleasure.
2007 Toyota Hilux
Maximum engine power of the 2.5 D-4D has been increased by seventeen per cent to 120 DIN hp (88kW) at 3,600 rpm with the introduction of a high performance turbo-intercooler and other developments. As a result top speed is now 165 km/h (4x manual transmission) and 155 km/h for 4x4 version.
At the same time the torque output from this engine is now at 325 Nm. Torque output is above 300 Nm from 1600 rpm to 2600 rpm, giving the 2.5-litre D-4D Hilux a very good balance between excellent driving pleasure and low fuel consumption in real world driving conditions. On the combined cycle, the 2007 Hilux 2.5-litre D-4D will deliver from 7.4 l/ 100 km to 8.3 l/ 100km, depending on the model.
The high performance, lightweight intercooler is positioned above the engine for maximum effect. It not only increases power but also offers enhanced emissions performance. Low speed torque is boosted by the inclusion of a two-stage swirl control valve, similar to the 3.0 D-4D, in the intake manifold which improves the swirl rate at low intake pressures.
Just as with the 3.0-litre engine, additional improvements to the emissions performance are achieved by fitting an Exhaust Gas Recirculation (EGR) cooler with integrated bypass and a switching valve to optimise EGR gas temperature.
These changes, and optimisation of the oxidation catalytic converter, ensure that the 2.5-litre D-4D is now fully compliant with Euro IV emissions standards. The 2.5-litre D-4D Hilux also offers customers excellent refinement and low noise levels, thanks to a series of measures to reduce noise and vibration. As with the .0-litre D-4D, improvements to the combustion process allow the compression ratio to be reduced to 17.4:1, giving more performance and reduced noise
