Scania’s heavy rigid gets more torque

The Scania 6×4 G-series rigid is now being offered with a larger engine, with the Scania G 540 XT now available across Australia.

With its 540hp six-cylinder SCR-only Euro 6-compliant engine delivering 2700 Nm of torque, the G 540 XT is designed to deliver more power and better fuel efficiency for tipper and dog operations.

Riding on an elevated chassis for superior ground clearance, the XT is equipped with quarry and construction site friendly features to protect the lights and the front of the truck, including a 150mm protruding steel bumper with integrated tow-hook, as well as a front under bumper bash-plate.

Aimed at the booming construction, civil engineering and infrastructure sector, Scania launched the XT range in late 2018 and the company says it’s been very well received by builders and contractors.

Building on those earlier renditions, the 540 XT is equipped with the most powerful six-cylinder engine in Scania’s family of lightweight, fuel efficient modular engines.

Scania’s typical tipper and dog specification for the G 540 XT has a 25,900kg GVM and a 75,000kg GCM.

As with the 540hp engine fitted to Scania’s intra and interstate haulage prime movers, in the 540 XT, the 2700 Nm of torque out-muscles its closest rivals by 100 Nm, which means hauling up an access ramp out of a quarry or out of a construction zone is made that much easier, as well as prompting smoother acceleration away from the traffic lights in built up areas.

Peak torque is available between 1000 and 1300 rpm. The engine majors on low-down driveability, with the torque to make shifting loads uphill seamless.

The 540hp engine is ideally suited to operations where there is a high demand for power and driveability, and where front axle weight is critical. The inline six-cylinder engine saves around 300kg over the front axle compared with the Scania V8s which have been very popular with tipper operators to date.

The 540hp engine adds 40 extra horsepower and 150 Nm more torque to the previous six-cylinder flagship, which nonetheless continues to be offered.

The performance enhancement to boost output from 500 hp to 540 hp comes from Scania’s XPI fuel injection, and a new ball-bearing fixed geometry turbocharger which delivers more useable grunt while retains exceptional fuel efficiency.

Updates include new friction-reducing coatings on pistons, rings and bores, increased compression rates and higher cylinder pressures, the adoption of smart auxiliary pumps, and modified inlet and exhaust manifolds, all of which work to reduce fuel consumption by up to 2.5 per cent.

Exhaust software control and updated aftertreatment also contribute to the overall fuel savings.

The 540hp engine is mated to a Scania GRSO905R overdrive 14-speed gearbox, with ratios selected via the Scania fully automated Opticruise gearshift, and braking is assisted by the Scania R 3500 Retarder. The G 540 XT is fitted with a class-leading cooling package for hilly terrain and heavy loads.

The G 540 XT tipper is also fitted with active and passive safety systems, including side curtain roll-over protection airbags and a steering wheel-mounted airbag as standard.

Further advanced safety features include advanced emergency braking (AEB), electronic stability program (ESP), lane departure warning (LDW), adaptive cruise control (ACC), driver and passenger seat belt pretensioners, auto hill hold, and LED head and taillights.

“Scania is very pleased to add the 540hp engine to the very successful XT family for construction and civil engineering tipper work. We expect this combination to be very popular as it offers an excellent mix of performance and economy,” said Dean Dal Santo, Director of Truck Sales for Scania Australia.

“Scania continues to provide greater torque than its rivals at identical horsepower outputs and the new 540 XT is no different, giving our customers an advantage in terms of driveability and fuel efficiency.

“The Scania 540 engine has proven itself to be frugal and powerful on Australian roads in the eight months that it has been available for haulage operations. We know that construction and infrastructure work has equally tough operating environments: high payloads, gruelling city driving in congested streets as well as for the drivers, long hours behind the wheel. That’s why the combination of Scania’s traditional strengths of comfortable and quiet operation will be enhanced further with the addition of this more potent, higher output engine,” he said.
