Toyota has added a workhorse bakkie to its new Hilux model

The workhorse is available with the 2.4 litre Global Diesel (GD6) engine that replaced the 2.5 litre D-4D. The new engine is said to brings with it a vast range of improvements in performance, refinement and fuel efficiency. It retains the proven DOHC 16 valve, inline 4-cylinder architecture.

Two iterations of the 2.4 litre mill are offered, with the standard version delivering 110 kW and 343 Nm between 1400 and 2800 rpm. This represents a 35 kW increase versus the old, and a colossal 143 Nm increase in torque which is a 72 percent improvement. The high-output version receives a boost in torque to 400 Nm, available from 1600 – 2000 rpm, constituting a 53 percent increase in tractive force. These significant improvements in output allow the new Hilux to punch above its weight.

An interesting note on the new 2.4 GD diesel engine is the reduction of compression ratio compared to the outgoing 2.5 D-4D powerplant. Even though diesels are designed to have high compression ratios, and high compression ratios provide efficiency, it’s not all good news.

A more forceful and violent explosion within the combustion chamber produces more noise in the form of diesel ‘knock’ and ‘rattle’, and potentially more engine vibration. High compression ratios also produce more environmentally damaging oxides of nitrogen, commonly referred to as NOx.

This reduction in compression ratio therefore contributes to a smoother and quieter running engine, which culminates in a more refined powertrain, as well as a reduction in emissions. Toyota’s engineers have managed to improve output and thermal efficiency, despite the reduction in compression ratio – creating a win-win situation.

As part of the overall grade strategy of the new Hilux line-up, “mid-grade” engines are paired with “mid-grade” specification packages, in order to provide maximum value to the customer and align the overall package with the requirements of the target market. As such the 2.4 family of engines perform duty across all three bodyshapes, in the workhorse and SRX grade models. The utility focussed “workhorse” derivatives are equipped with the standard output 2.4 litre engine, making light work of any load and offering class leading torque output of 343Nm.

The mid-grade SRX models are specified with the high output 2.4 litre GD engine, which afford them exceptional performance credentials, whilst also being able to boast with a class leading torque output – weighing in at 400 Nm.

The SRX package offers customers a host of core convenience features and strikes a perfect balance between function and form. In addition to standard creature comforts such as power windows, a 12-volt power outlet, adjustable exterior mirrors, ABS brakes, remote central locking and an all-new anti-theft system – the SRX models further incorporate steering switches, Tilt & Telescopic steering adjustment (X/C and D/C only), an economy meter, Multi Information Display, Audio system with Bluetooth and USB playback, as well as 17” steel wheels. On the passive safety front, occupants are protected by driver, passenger and driver knee airbags, with ISOFIX attachment points and a 3-point rear centre seatbelt being added to double-cab models.

Forming the link between the advanced new engines and the driven wheels, are all-new slick 5 – and 6-speed transmissions. Workhorse models are equipped with a rugged 5-speed manual transmission with the SRX versions receiving a slick-shifting 6-speed manual. The new transmissions help make the make the most of the 2.4 litre engine’s power delivery and provide an effortless drive with carefully spaced gear ratios. SRX models equipped with the 6-speed transmission proudly sport the ‘2.4 GD-6’ moniker on the fender, whilst workhorse models omit the 6 in their nomenclature, to denote the fitment of a 5-speed cog swapper.

All models are accompanied by a 5 year or 90 000 kilometre service plan (whichever occurs first) with service intervals set at 10 000 kilometres.
