Cummins unveils integrated powertrain

In recent years, Cummins has gone through a remarkable transformation, becoming a genuine powertrain supplier – from engine to transmission to axles and brakes.

Now for the first time, Cummins will showcase its new integrated powertrain at the upcoming Brisbane Truck Show next month.

This world-first display will feature the integration of a Cummins X15 engine, Eaton Cummins 18-speed Endurant speed transmission, and Meritor driveline and axles.

Cummins’ acquisition of Meritor in 2022 was a critical step for the company to be able to roll out a completely integrated powertrain.

The Brisbane Truc k Show will be the first opportunity for the brand to display the combined forces of Cummins and Meritor at an Australian truck show.

While the Meritor business now operates under the banner of Cummins Drivetrain and Braking Systems (CDBS), the Meritor brand is retained for axles and brakes.

“The Brisbane show will be a great opportunity to see the result of the Cummins-Meritor integration and the benefits it offers customers as we bring together complementary power technologies to seamlessly enhance efficiency, performance and lower emissions across the powertrain system,” said David Cole, Managing Director of CDBS Australia.

“For customers this means lower total cost of ownership and having confidence in system dependability, backed by comprehensive Cummins support across the powertrain.”

HELM innovation

Cummins’ fuel agnostic HELM capability with its X15 engine platform will also be showcased at the Brisbane Truck Show.

“HELM – higher efficiency, lower emissions, multiple fuels – highlights the innovation that is powering us forward,” said Sean McLean, Director and General Manager of On-Highway Business for Cummins Asia Pacific.

The HELM engines are an important element of Cummins’ Destination Zero strategy to go further, faster to reduce the greenhouse gas (GHG) and air quality impacts of its products.

The industry-first HELM platform basically comprises one block and three-cylinder head options – a compression ignition head for diesel, and spark ignition heads for natural gas and hydrogen (a zero carbon fuel at the tailpipe).

This will be the 15-litre platform for future diesel development and will be released in OEM (original equipment manufacturer) applications for the Australian market in coming years.

The natural gas version of the X15 – the X15N – is now in full production, at Cummins’ Jamestown engine plant in the US, while the hydrogen version – the X15H – is expected to become available later in the decade.

The X15N, the first natural gas engine to be designed specifically for heavy-duty truck applications, is offered with maximum outputs of 500 hp and 1850 lb ft of torque. The X15H will have higher peak outputs of 530 hp and 1900 lb ft of torque.

New X10 engine

Cummins’ new HELM X10 engine will also be displayed at the show.

The X10 is a brand new 10-litre platform to be launched in North America and Europe in 2026 and other global markets at a later stage.

While the X10 has fuel agnostic capability and is able to run on hydrogen and natural gas, the diesel version will be available first, compliant with the ultra-low U.S. EPA 2027 and Euro 7 emission regulations.

Diesel will remain a critical technology for the on-highway market for years to come, and Cummins will continue to support it.

“We are committed to advancing diesel technology while our markets and our customers need it to run their businesses,” said Sean McLean.

The diesel X10 will be available with ratings up to 450 hp and peak torque of 1650 lb ft, outputs that will suit short haul and regional trucking operations as well as bus and coach applications.
