Terex Trucks brought its new Stage V TA300 and TA400 articulated haulers to the Hillhead Digital exhibition, which took place at the end of March. The machines have been updated with an EU Stage V emission-compliant engine – and now deliver an improvement in fuel efficiency, an even stronger performance, as well as low total cost of ownership.

Both haulers now boast a reduction of up to 7% in fuel consumption when compared to the Stage IV engine. Customers in Europe will also benefit from the haulers’ strong engine performance and excellent responsive power in all conditions. Equipped with a Variable Geometry Turbo (VGT), the new Stage V engine allows for faster response at all engine speeds and an efficient combustion performance. All of this helps improve operators’ efficiency while keeping the total cost of ownership low.

The TA300 and TA400 Stage V engine’s effective aftertreatment system uses selective catalytic reduction (SCR) technology, removing the need for exhaust gas recirculation (EGR). This way, no exhaust gas is returned to the combustion chamber of the engine, helping to improve efficiency and durability of the machine. The diesel oxidation catalyst (DOC) and a large-capacity diesel particulate filer (DPF) ensure the engine meets the latest EU emission standards.

Just like the firm’s Stage IV haulers, the new Stage V TA300 and TA400 are equipped with Scania DC9 and DC13 engines. Thanks to a drivetrain that’s perfectly matched with the engine, the trucks deliver a powerful performance and excel in demanding work environments. For heightened levels of operational safety and control, an engine exhaust brake is installed as standard; this also reduces brake component wear. The haulers come with three-stage aspirated air filtration, which provides increased engine protection to lengthen maintenance intervals. All of this helps deliver strong, durable engine performance and keeps the total cost of ownership low.
