Hilux 2012: Upgraded 2wd 2.5 d-4d, Hilux 2012 engine range now euro v compliant

Through the introduction of variable nozzle turbocharging, Hilux 2012 2WD, 2.5 D-4D models now benefit from a 24 hp increase in power. The improved 2,494 cc, 16 valve, DOHC four-cylinder common-rail unit now develops 144 hp at 3,600 rpm and 343 Nm of torque at 2,000 rpm, matching the output of 2.5 litre four-wheel drive variants.

This power increase has been achieved through the adoption of a DC motor-actuated, variable nozzle vane-type turbocharger and the use of new injectors. The new injectors offer more precise fuel injection, improving throttle response and performance.

Durable, reliable and quiet, the 2.5 D-4D engine further benefits from several performance and efficiency enhancing measures. A high-performance turbo-intercooler not only increases power but also enhances emissions performance. A sophisticated Swirl Control System optimises the air-fuel mixture at low engine speeds, increasing torque availability without the need for acceleration. And an Exhaust Gas Recirculation (EGR) cooler optimises EGR gas temperature to improve emissions performance.

As a result of the 24 hp power increase, the Hilux 2012 2.5 D-4D 2WD accelerates from 0-100 km/h in 14.1 seconds, and has a top speed of 170 km/h.

Despite these significant performance increases, combined cycle fuel consumption has been reduced by 1.0 l/100 km to 7.3 l/100 km and CO₂ emissions lowered by 26 g/km to only 193 g/km.

Complimenting this power increase, Hilux 2012 2WD versions are now equipped with the more robust chassis design of 4WD models. This not only improves vehicle ground clearance, but also increases the two-wheel drive models' towing capacity to 2.5 tons.

The 3.0 D-4D engine, a 2982 cc, 16 valve, DOHC four-cylinder common- rail turbodiesel, develops 171 hp at 3,600 rpm and 343 Nm of torque from 1,400 to 3,400 rpm when mated to a 5-speed manual transmission. Equipped with an optional, 5-speed automatic gearbox, the unit's maximum torque rises to an impressive 360 Nm from 1,400 to 3,200 rpm.

Only available in 4WD format, the 3.0 D-4D with manual transmission will accelerate from 0-100 km/h in 12.1 seconds, and has a top speed of 170 km/h. It returns an average fuel consumption of 7.6 l/100 km, and generates CO₂ emissions of 199 g/km.

Mated to the 5-speed automatic gearbox, the 3.0 D-4D's 0-100 km/h acceleration improves to 12 seconds, and top speed rises to 175 km/h. Average fuel consumption is 8.6 l/100 km, with CO₂ emissions of 227 g/km.

The manual transmissions of both the 3.0 and 2.5 litre D-4D engines are especially smooth at tick-over, which makes driving in 1st gear on engine idle a smooth and controlled, walking-speed experience. This allows steep descents in rugged terrain to be made without losing control of the vehicle. This superior control and high torque output allows the Hilux 2012 to climb steep slopes on engine idle only with equal ease.

Both units benefit from high torque output across a wide engine speed range -the 2.5 D-4D generating 343 Nm between 1,600 and 2,800 rpm, manual versions of the 3.0 litre engine matching this figure between an even wider, 1,400-3,400 rpm band- offering optimum performance at any speed, across any terrain.

Thanks to the adoption of a Diesel Particulate Filter (DPF) both 2.5 D-4D and 3.0 D-4D engines are now EURO V compliant. The DPF system collects and regenerates PM (Particulate Matter) in exhaust gas and efficiently oxidizes carbon monoxide and hydrocarbon.
