Hyundai's new HX520 L is powered by a 331-kW (445-hp) Scania D13 engine, which is compliant with the Stage IV emissions standards. Hyundai has chosen a combined EGR and SCR technology solution that it says results in a reduction of fuel consumption of 3 to 6% depending on work cycles.

The 52-t (57-ton) HX520 L comes with a 3-m³ (4-yd³) bucket as standard. The bucket has a digging force of 280.5 kN (31.5 ton) and 11,870 mm (470 in) maximum digging depth, making it suitable for large building and excavation tasks. The South Korean manufactured excavator also accepts a wide selection of attachments.

The cabin has also been re-designed—a new larger front screen has been incorporated and the driver's door is now easier to open from the inside with an additional handrail. The interior of the HX-cab offers 10% more space for the operator. A newly developed air conditioning system provides better air circulation in the cab.

Considered by the company one of the most important innovations on the new HX series is the new and larger 8 in interactive touchscreen monitor—which can be operated when wearing gloves. It’s also easy to read and the main view of the screen can be adjusted according to the preferences of the driver. It can be controlled via touch control and/or new haptic control switch, which is common in passenger cars. The connection to a mobile phone is easy, as is the connection with external cameras for complete 360°-visibility. Also maintenance and engine data such as fuel consumption, engine rpm, hydraulic pressure, etc. can be checked immediately by the operator.

New on all Hyundai HX excavators is the Intelligent Power Control (IPS). This new device monitors the pump performance and adjusts it to the actual flow patterns in the hydraulic system. Many new components have been integrated into all HX excavators—this includes swing and travel motors, which Hyundai now designs inhouse.

The first HX models are expected to be available first for the European market by the end of 2015. The HX series ranges from 12.5 to 90 t (13.8 to 99 ton).
